    MEADS at Crossroads – Or Not?

    http://defpro.com/daily/details/561/ | It is fairly normal (isn’t it?) for major defence programmes to hit a serious bump or two along their development and procurement road. But beyond this, for some unfathomable reason, certain programmes appear to be both cursed by a whole series of hiccups and resulting repeated attempts at folding them down, and blessed by an uncanny ability to survive against all odds and endure unscathed through technical difficulties, budget cuts and waning operational requirements. In this particular category, a prominent place must certainly be reserved for the MEADS (Medium Extended Air Defence System) programme, being pursued (well, sort of) in international cooperation involving the United States, Germany and Italy.

    Retracing the ups and downs of the MEADS effort over the past years would take a massive book, so let’s go straight to a synthetic description of the latest bump. Basically, another billion dollars or so of taxpayer’s money would need to be pumped into the development phase, if this is ever to be completed. Now, cost increases are hardly a new experience in defence, but in this specific case there is a palpable lack of enthusiasm amongst the three partners towards coughing up the required money. Most particularly, the pursue-strings holders in Germany have made it officially clear that the money simply isn’t there, period.

    Which brings us straight to the respective advantages and pitfalls of international cooperation programmes in defence procurement under the multiple operational, political and industrial points of view.

    The US Army seems to have very little residual interest in MEADS, and it even tried (unsuccessfully, as it was) to dump the programme onto the Missile Defense Agency. Basically, under the current situation of tight money, the Service’s medium-range air defence and tactical ballistic missile defence requirements could sort of be satisfied by the combination of the existing PATRIOT (possibly further upgraded beyond the current “Pure Fleet” effort) and THAAD systems. Germany could also accommodate itself to a roughly similar arrangement, should THAAD eventually be selected (which looks like a foregone conclusion) for the NATO’s upcoming missile defence programme. Italy does not currently deploy the PATRIOT, and thus abandoning MEADS would necessarily imply extending the current SAMP/T procurement and joining France for the development of an ATBM version of the ASTER 30 missile. Now this would admittedly force the Italian Air Force into the outrageous proposition of having to deploy the same air defence system as the Army, but, hey, nobody ever said life is fair.

    Given the above, the official glue that still keeps MEADS together is largely political. International cooperation programmes are notoriously difficult to kill (this being arguably one of the main reasons for selecting this approach in the first place), and furthermore it now so happens that MEADS is the last surviving major trans-Atlantic effort. It is thus only too understandable that Washington, Berlin and Rome would be very wary of being perceived as the unreliable partner that renounces its commitments and leaves the others in deep trouble; and would be willing to keep MEADS alive even through and beyond circumstances, that would be more than enough to cause the demise or a purely national effort.

    Plus, of course, the, say, varied picture of industrial interests, and the impact these interests might or then might not have on the governments’ attitudes and decisions. It is no secret that a certain US defence major would have a vested interest in sending MEADS down the drain in favour of a further revamped PATRIOT, and it is actively exploring ways to ensure that this will indeed be the case. As for the MEADS International consortium, there are unmistakeable signs to indicate that the European part of it has already started formulating a “Plan B”. This would involve most notably finding ways to complete the development programme as currently underway for the MEADS radar, and identifying a possible alternative operational use for it that would justify procurement in at least limited numbers.

    Be this as it may, in political terms Germany now appears to hold the keys for whatever future is in store for MEADS. Washington would almost certainly not wish to cancel the programme on its own and be seen as “betraying” Europe, while a conceivable unilateral departure of the Italian 17 per cent would not be enough to kill MEADS. But if Germany’s 25 per cent goes, for whatever reason, then that’s it.

    But even from a political point of view, it is a fair bet that on the European side industrial considerations would have an even larger influence on the decision-making process than it is usually the case. Both the German and Italian governments are firmly in support of close ties with Washington, and they can thus be counted upon being more than prepared to save a trans-Atlantic programme for its own sake if they only can decently do so without imperilling domestic support. Given this, if industry this side of the pond starts crying foul and threatening that the demise of MEADS would lead to job losses, plant closures and the like, then the beancounters’ resistance will easily be broken, and money to save the programme will be found. But if, on the other hand a least a solid majority of the European industries currently involved in MEADS can accommodate themselves to a “Plan B”, then the future of the programme looks uncertain indeed.

    What is lamentably missing in the whole affair is a serious analysis as of whether or not the operational requirements that did originally lead to the three countries joining forces for the MEADS programme still stand in the current scenarios, together with an in-depth discussion on the roles MEADS (which along its development path has metamorphosed into a very different beast than originally envisaged) will or would play. But this is, I’m afraid, an only too common occurrence in contemporary defence procurement – whereby the needs and ideas of the Services play a very distant third fiddle to political and, increasingly, industrial issues.

    In a world where the British Defence Secretary finds its quite normal and logical to present an order for two additional ASTUTE-class SSNs (for the not totally insignificant cost of £300 million) without even mentioning the Royal Navy’s operational requirements, and rather by commenting at length about the situation of the British shipbuilding industries and the need to preserve jobs and skills there, it would certainly not be surprising if MEADS finally meets its fate, or rather is once again saved like the perpetual Phoenix, for reasons that have a precious nothing to do with what the US, German and Italian military might think or wish.

    Economic Downturn Forces Malaysian MiG-29s to Continue Flying

    1993 – 2009 16 years i guess (the first ones atleast)

    Defence Ministry decides to upgrade MiG-29Ns for continued operation until 2015
    http://www.defpro.com/daily/details/518/

    defpro.com | The Malaysian Government last week announced that it would continue to operate ten of its 16 MiG-29N interceptors, reversing plans announced late last year to decommission the entire fleet of by the end of 2010. The original plan by the Ministry of Defence to replace the MiG-29N fighter jets with the ‘Multi Role Combat Aircraft’ (MRCA) has been delayed by the economic downturn, a ministry official told reporters. As defpro.com previously reported in November last year, the Royal Malaysian Air Forces’ (RMAF) plan to purchase a new fleet of fighter aircraft faced serious financial obstacles (see: http://www.defpro.com/daily/details/438/). On Wednesday last week, the defence ministry confirmed that due to the postponement of the purchase of new fighter jets, the retirement of its Russian-made MiG-29N would be delayed for at least five years.

    “We have decided to continue using ten of the 16 MiG-29N jet fighters after sending them for repairs and upgrades,” the New Straits Times quoted Defence Minister Datuk Seri Dr Ahmad Zahid Hamidi as saying. “We initially wanted to ground the [MiG] jets and sell them to a third country, but after much thought and deliberation, we have decided to hold on.”

    The global economic downturn appears to have put a damper on Malaysian defence procurements. Since 2008, Kuala Lumpur has been careful not to announce any major orders but, rather, proceed with ongoing commitments. The defence procurement budget remains under strain as the government focuses on economic recovery.

    The 10th Five-Year Malaysian Plan (2011-1015), which is to be submitted to Parliament in June 2010, is expected to propose procurement and development funding of RM7 billion ($2.07 billion / €1.51 billion) for the entire defence and security sector, with approximately RM5 billion being allocated for defence proper. It is further understood that nearly half the total amount would be invested to replenish war stocks (missiles, bombs and ammunition), with relatively little money being left for new procurement efforts. Also, at least 30 per cent of the available money would be reserved for purchases from the national defence industry. Clearly enough there is no way the purchase of 18 new generation aircraft could be financed under these conditions.

    The MiG-29N aircraft played the role of interceptor jets and 18 of the fighter jets were purchased for the RMAF in 1993 for $380 million. However, two of the aircraft crashed in 1998 and 2005 while six others have been decommissioned. Malaysia was the first non-Soviet block country to acquire Russian combat aircraft and was expected to float a request for proposal (RfP) for 18 new-generation fighter aircraft to replace the MiG-29Ns.

    In December last year, former premier Mahathir Mohamad criticised the phasing out of the jets as a waste of money. In his blog, he said the aircraft have a life span of at least 20 years and could remain in service till 2013/2014. He also compared the purchase of the MiG fleet to the Boeing F/A-18D Hornets, which are also in service with the RMAF. He said that the US fighters have longer life spans but are too costly compared to Russian aircraft and have too many restrictions, as the entire technology of the aircraft is kept secret.

    However, by keeping ten MiG-29s in service the Defence Ministry will have major expenditures for repairs and upgrades of the aircraft, as well as costly maintenance. The aircrafts’ engines need to be overhauled every year and the maintenance costs may rise to over €60 million (~$82 million) annually. Beyond that, the weaponry for the fighter jets has reached the end of its life span and extending the life span would not be viable.

    Further, the plan to acquire new aircraft could be back on the table in 2015, the Defence Minister said. “After the global economy shows signs of recovery, we may be able to proceed with the plan,” he noted.

    US KC-X Tanker Competition: Just Once More, Please

    US DoD issues revised request for proposals for new US Air Force aerial tanker
    http://www.defpro.com/daily/details/516/

    defpro.com | Yesterday, US Air Force and Department of Defense (DoD) acquisition officials informed Congress and members of the press on the revised request for proposal (RfP) for the competition for a new aerial tanker. The officials claim that RfP for the controversial KC-X programme, which is now entering its second attempt of finding a solution for the future of US Air Force air-refuelling, is designed to promote fair, open competition. However, it is still questionable if there will by any competition, as the Northrop Grumman-EADS consortium, having been awarded a contract in 2008 which prompted a protest from rival bidder Boeing, threatened that it would not solicit a bid, should it be convinced that the competition is not fair.

    The $50 billion programme to replace the ageing KC-135 Stratotanker fleet of the US Air Force, has turned out to be a political-industrial marathon, with an exceptionally strong focus on the basic parameters and proceedings, rather than on the aircrafts’ performance and . In particular the Air Force, which has an urgent requirement for a new refuelling aircraft, was pushed to the limit of its patience. Putting it in a nutshell, then-Commander of the Air Mobility Command (AMC), General Arthur Lichte, exclaimed: “I don’t care which tanker wins, I just need a new tanker!”

    With the long awaited release of the final terms of the competition, the US officials attempt to provide a more transparent process and answered 350 separate questions, as the Financial Times reported yesterday. The highly details RfP includes 372 mandatory requirements and incorporates 230 mostly technical charges in response to comments on a draft document issued in September. According to Deputy Defense Secretary William J. Lynn III, the new RfP recognises the high stakes in the determination in terms of jobs as well as revenues and “buffeting” from both competitors, Boeing and the Northrop Grumman/EADS team.

    According to different news reports, an EADS spokesman said the company would study the new terms when they were issued. Despite Northrop Grumman’s threat to withdraw from the competition, Defence Secretary Robert Gates expressed his hope that both competitors would participate in the bidding. In a step which might not be the wisest, EADS receives support from French Defence Minister Hervé Morin, urging Washington to give the consortium a fair chance. Defence experts have repeatedly expressed the opinion that the Northrop-Grumman/EADS solution would have a hard time in the competition due to the fact that a European industry partner is involved, while Boeing would appear to be the more “patriotic” choice. While during the first bidding, EADS was omnipresent in the news, promoting its solution wherever it could, it may be politically wiser to place Northrop Grumman into the focus this time.

    Should the transatlantic consortium decide to enter the race for a second time, it will do so with a strong platform. While both platforms are designed to meet the requirements of the Air Force, the KC-45 by far exceeds many of the requirements. In fact, the 2008 decision in favour of the KC-45 is primarily attributed to its capacity, carrying about 45,000 lbs more fuel than the current KC-135. As a consequence, Boeing used the delay in the competition to revise its strategy and put the larger 777 platform into the race. The Boeing 777-based tanker is comparable in size to the Airbus A330, which is the basic airframe of Northrop Grumman’s KC-45, but delivers 54,000 lbs, or 23 per cent more fuel.

    In an ongoing voting at defpro.com, the Northrop-Grumman/EADS solution maintains a significant lead with 54.29% over its competitor, Boeing. The latter received support by only 33.8% of the voters while a mixed solution is favoured by 11.91% (see http://poll.fm/1ai5f). However, while this poll represents international opinions, the decision will be made in the US and will include (next to the requirements of the Air Force) domestic factors such as employment, distribution of the manufacturing activities, and the shaping of US aerospace industry’s future.

    Eurofighter Typhoon Heads to India for MMRCA Evaluation

    Eurofighter Consortium eyes $10.4 billion contract for future Indian fighter aircraft
    http://www.defpro.com/daily/details/508/

    defpro.com | Coinciding with the starting signal for India’s largest defence exhibition, DEFEXPO 2010 (15-18 February 2010), a German Air Force Eurofighter fighter aircraft will be heading to India today. However, this aircraft will not be making acrobatic manoeuvres for the visitors of the show but, rather, will be thoroughly examined by the Indian Air Force (IAF) as part of the medium multi-role combat aircraft (MMRCA) MMRCA programme. The Eurofighter will join India’s ongoing programme, which has been initiated in August 2007 and is currently in the process of testing all participating contenders, to undergo trials until March in Bengaluru as well as in Jaisalmer and Leh. The two latter stations will demonstrate the Eurofighter’s desert and high altitude performance.

    As 8ak.in recently reported, the prospects for a success of Eurofighter in India still are difficult to judge, as the European consortium is receiving mixed signals from Indian officials. While there is general consent that the performance of the aircraft is up to the expectations, the pricing reportedly is an issue. Reuters news agency quoted India’s Ambassador, Arif Shahid Khan, saying Eurofighter Typhoon is leading the race to win the new fighter deal with the Indian Air Force. The Ambassador stressed the top position held by Eurofighter Typhoon during a meeting in late January with Italian Prime Minister Silvio Berlusconi in Rome.

    However, a technical triumph of the Eurofighter in the evaluation phase would not automatically mean that the Eurofighter consortium will be awarded the contract for the 126 required aircraft, worth an estimated 10.4 billion. As 8ak.in explains, EADS (holding 46% in the four-nation Eurofighter consortium) has already had bad experiences with Indian procurement procedures in the past. Despite the IAF’s full approval of the procurement of Airbus tanker aircraft, the Indian finance ministry brought these plans to a sudden end, saying it would be too expensive.

    The Eurofighter is competing against Dassault’s Rafale, Saab’s JAS 39 Super Gripen IN, Boeing’s F/A-18E/F-IN Super Hornet, Lockheed Martin’s F-16IL and Russia’s MiG-35. According to the Eurofighter Press Office Blog, the Eurofighter Typhoon offers a broad spectrum of operational advantages to India, such as its adaptability to severe weather conditions, high mission effectiveness and survivability in threat situations as well as considerable in country economic benefits.

    Bernhard Gerwert, chairman of the supervisory board of Eurofighter GmbH and CEO of Military Air Systems, a business unit of EADS Defence & Security (DS) said: “We are well positioned in the ongoing tender […] because the Eurofighter Typhoon is the ideal answer to the threats that India faces.” He added “The aircraft’s outstanding operational performance, coupled with low life-cycle costs and a tailor-made industrial partnership offer, make the Eurofighter Typhoon a key contender in India’s competition.”

    Eurofighter will attempt to demonstrate the aircraft’s claimed advantages at the DEFEXPO show, where its stand will showcase a Eurofighter simulator. A success in the Indian fighter race would be a bonanza for the consortium which is searching for additional export customers since quite a while. Enzo Casolini, CEO of Eurofighter GmbH, told the Indo-Asian News Service: “We evaluate the global demand for combat aircraft in the next 20 years at around 800 units. For Eurofighter Typhoon, we target 300 additional export contracts, with Asia representing a substantial part of these orders.”

    So far, the only export successes for the Eurofighter have been Austria and Saudi Arabia. While the Austrian procurement programme suffered from a controversial political and financial debate, resulting in the procurement of only 15 aircraft, the Saudi Kingdom ordered a total of 72 aircraft in late 2007.

    As 8ak.in points out, the engine question (always being one of the most prominent field of interest in a fighter aircraft programme) may further support Eurofighter’s position in the MMRCA race. EUROJET Turbo GmbH is not only providing the engine for the Eurofighter but is, furthermore, interested in extending its industrial presence in India (see http://www.defpro.com/daily/details/502/). EUROJET recently announced that, if required, they are willing to transfer their single crystal turbine blade technology to India. According to company sources, the technology transfer is currently not under the scope of the Light Combat Aircraft (LCA) engine request for proposal (RfP). However, the news service states “it makes commercial sense for India to choose the same engine for the MMRCA that they would choose to power the Tejas.”

    Part 2 of a comprehensive overview on Sukhoi’s 5th generation fighter

    http://www.defpro.com/daily/details/506/

    06:53 GMT, February 11, 2010 On 29 January 2010, the Sukhoi PAK-FA (Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsy, literally “Future Front line Aircraft System”), which could variously be described as a technology demonstrator, the first prototype of the future T-50 fighter, or an intermediate step between the two, took to the air for the first time from the freezing runway of Dzemgi Air Force Base (shared with the KnAAPO plant) at Komsomolsk-on-Amur in the Russian Far East Siberia (see also http://www.defpro.com/daily/details/497/). A fundamental step has at last been accomplished in the development of the long-expected Russian response to the American F-22 RAPTOR air dominance fighter.

    (Part one of the article can be viewed here: http://www.defpro.com/daily/details/505/)

    Airframe

    The aerodynamic configuration of the PAK-FA maintains a vague reference to the Su-27 as regards the fuselage and the location of the engines, which are installed in widely separated nacelles forming a tunnel with the flat bottom of the fuselage. The general planform is a tailed delta, similar to the F-22, with the all-moving horizontal tailplanes close-coupled and on the same plane to the wing without any gap. The twin vertical surfaces, canted outward by perhaps 25°, are also all-moving. This solution has been used rarely in recent times; in particular the ill-fated Northrop YF-23 had a pair of all-moving butterfly tailplanes. The all-moving verticals however had been fairly used in supersonic designs dating back to the late 1950s or 60s, in particular the SR-71 which used a pair of all-moving verticals canted inward to reduce the induced roll moment when the surfaces were rotated, and most of the North American design of the period – the RA-5C VIGILANTE, its contemporary YF-107 and the unique XB-70 – as well as the British BAC TSR 2 used a similar solution. In the PAK FA design, their reason d’être arguably consists in enabling the smallest possible vertical surfaces for the sake of reduced radar signature and supercruise drag, while at the same time also maintaining (in combination with the 3D TVC nozzles) excellent manoeuvrability.

    The underfuselage tunnel between the engine nacelles contributes significantly to the overall aerodynamic lift generation, just as in the Su-27 and MiG-29 as well as in the F-14 – arguably the real originator of the “centreplane lift” concept. This lift is added to that provided by the large wing and should enable excellent manoeuvrability even at high altitude – a potential advantage of the F-22 and now the PAK FA over all their rivals. The widely separated engines also offer much better survivability in the event of battle damage or accidental fire/explosion.

    The fuselage sides have marked “chines”, again like the F-22 and its unfortunate competitor, the YF-23. This shaping can be assumed both to contribute toward reducing radar reflectivity and to develop, at high angles of attack, favourable lift-enhancing vortexes flowing above the inner wing upper surface just above the engine nacelles. The wing has dropping leading edges providing for a variable camber airfoil and separate flaps and ailerons, these latter contributing towards enhanced TO/landing performance (this should anyway be very good, given the huge lift generated by the aircraft configuration as a whole). The inner part of the wing leading edges is stepped longitudinally with a much longer chord which blends forming, in part, the engine nacelles’ upper “lips” and then merging into the fuselage to enhance the lift generating characteristics of the overall aircraft configuration, somewhat akin to a lifting body. Possibly for this reason, but also to ease a smooth airflow into the engines at very high angle of attack, the upper intake projecting false “lips” appear to be hinged parallel to the sweep real intake lips, thus providing a variable camber like the wing leading edge. In this way, the upper surface of the air intake contributes to overall lift generation. It is also possible that the movements of these peculiar elements, when linked to the full authority digital flight control system, could contribute in some way to the aircraft’s longitudinal control, acting like a third control surface (in line with the Sukhoi tradition as exemplified in the three-surfaces Su-30MKI). It seem however clear that the “lips” cannot move as fully independent control surfaces, due to their primary role in ensuring a correct airflow to the engines.

    The possible rationale behind the fuselage “chines” and wing strakes could be to generate two vortexes over each wing upper surface, thus enhancing lift (via more diffused vortex lift) at high angle of attack (AoA). In particular, the two inner vortexes (those generated by the fuselage “chines”) would energise the airflow over the inner wing upper surface blending with the fuselage above the engine nacelles. The two outer vortexes (those generated from the wing strakes outboard the intakes lips) would transfer their kinematic energy to the upper outer panel wing airflow. Furthermore, given the expected path of such latter vortexes, they would also interact with the upper airflow over the all-moving horizontal tailplanes – thus replicating the superior longitudinal control provided in the Su-27 by its peculiarly located slab tailplanes.*

    Summing up, lift appears to be generated by following elements, working in a synergic way:

    • Wing outer panels (outside the engine nacelles) with dropping leading edges (variable camber airfoil);
    • Engine nacelles upper surface blended with outer wing panels and fuselage with dropping intake upper false lips/leading edges (variable camber);
    • Fuselage tunnel between the engine nacelles;
    • Vortexes generated from the front fuselage “chines“, enhancing the engine nacelles upper surface lift and possibly the all-moving verticals’ control authority at very high AoA;
    • Vortexes generated by the wing strakes outboard the engine nacelles, enhancing the outer wing panels lift and possibly the all-moving horizontal tailplanes control authority at very high AoA.

    The fuselage has the already mentioned flat bottom and a straight tapered upper part ending in a flat and somewhat smaller “sting” between the engine exhausts. The installation of a braking parachute in a bay in the upper part of the sting makes room for the rational introduction in the extreme tailcone of a wide-scanning ECM antenna or perhaps a rear hemisphere surveillance/tracking radar (experiments were carried out a few years ago on a modified Su-32FN). The second prototype, which was used for taxi trials on 23 January appears to have a different tail cone, for unclear reasons.

    The rear fuselage beavertail appears wider than in the Su-27/-30 albeit with a similar layout, and should offer more freedom of movement to the multi-axis thrust vectoring control (TVC) exhaust nozzles which will most certainly be fitted to the engines of the T-50 (although their current presence on the PAK FA is not certain). This configuration with the widely exposed round engine exhaust nozzles is however detrimental in terms of rear-emisphere IR and radar signature.

    The PAK FA is claimed by Sukhoi to offer “unprecedented small signatures in the radar, optical and infrared range”, and this is certainly true as regards Russian combat aircraft and quite possibly all existing non-American designs. At the same time, it is evident that the PAK FA has been designed with a close attention to stealth characteristics, but is not intended to be an uncompromising stealth aircraft à la F-22. When certain design features detrimental to low observability were deemed to be all-important, these were adopted nonetheless. It would be extremely interesting to watch the eventual results of this approach in terms of maintainability and operational availability, particularly in the light of the in-service experience so far with the F-22.

    An element which maintains some similarity to the Su-27 family is the landing gear. All the members retract forward, easing the emergency extension which in this way can be accomplished simply by gravity and air pressure. The main tyres, again like the previous Sukhoi design, when retracted lays flat in bays partially above the air intakes and partially inside the thick wing root fairing born out from the air intake upper part and as a continuation of the sweep surface linking the fuselage side to the outer wing, running above the upper air intake lip.

    The PAK FA appears to be built with a significant percentage of composites, including most of the wing, horizontal tailplanes and dropping intake lips skin, centre-forward engine nacelles, most of the fuselage skin and the doors of the weapons bays and landing gear bays. Metal parts seem to include the dropping wing and intake lips leading edges (with the exception of the inner sections where the conformal aerials are expected to be installed, and which should thus be built of dielectric material), the engine intakes and the wide fairings blending the outer wing panels to the fuselage. Press reports suggest a 75% (being weight) being made of titanium alloys and 20% by composites, which sounds plausible.

    Powerplant

    The planned engine for the T-50 is understood to be the new Saturn AL-41F, expected to offer about 17.5 tons of thrust in full afterburning mode and somewhere in the range of 12 tons in dry mode. The latter figure would comfortably enable supercruising (i.e., supersonic cruise flight without afterburner) at around Mach 1.5, thus in the same class as the F-22. The prototype/technology demonstrator now flying was expected to be powered by the Saturn 117S, a much improved version of the AL-31F intended for the Su-35 but still less powerful at 14.5 tons in full afterburning than the AL-41F. There however are some indications to suggest that the aircraft already has the new engines.

    The engines are fed by two-dimensional raked air intakes with the upper lip generating an oblique shock wave favourable to dynamic pressure recovery in the supersonic regime, which for the PAK FA could approach Mach 2.3÷2.5. While in appearance of fixed geometry, it is possible that a variable-position upper ramp, to generate multiple oblique shocks is part of the system for a further better dynamic pressure recovery in the high supersonic speed regime.

    The tight shape of the engine nacelles and the position of the ventral “venetian blind” auxiliary intakes seem to suggest that the PAK FA does not feature a serpentine air duct to the engine compressors, as typically adopted for low-RCS aircraft. It is possible that the Sukhoi designers have preferred to limit the compressors’ strong radar reflection by inserting a grill in front of them, while optimising the air intakes for higher max. speed and supercruise performance.

    The engines are mounted with a slight forward convergence (some 3°). This, in twin-engine aircraft with conventional exhaust nozzles, would typically reduce thrust asymmetry in the event of an engine flame-out – although with the drawback of reduced controllability. Given however the installation of TVC nozzles, the choice of converging axis built into the nacelles could be the outcome of an aerodynamic local airflow optimisation due to interaction of all the aircraft elements.

    A large fuel capacity in line with the previous Sukhoi fighters is certainly provided, let’s say in the order of 12,000 litres. A fully-retractable in-flight refuelling probe is installed on the left side of the fuselage in front of the windscreen.

    Armament

    The standard air-to-air armament is carried internally in two identical tandem weapon bays, which can be estimated at about 5m x 1.2-1.3m. The bays’ position inside the tunnel between the engine nacelles ensures a discrete opening of their doors at weapons launch, otherwise a drawback for a stealth aircraft. In addition, the doors have saw tooth-shaped edges to further reduce radar signature. The size of the bays can be assumed to allow internal carriage of eight R-77-class radar-guided AAMs with folding wings, i.e. the same figure as for the F-22.

    Similar to American 5th generation types, for the “second/subsequent” days of war operations, four additional underwing hardpoints can be installed under the outer wing panels. However no wingtip store positions appear to have been foreseen. A dark area to the right side of the upper front fuselage under the cockpit betrays the installation, similarly to the Su-27, of a single cannon (a 30mm GSh-30-1?) for close combat engagements.

    Avionics

    The combat avionics of the T-50 has been under development for some time, and some elements will almost certainly be installed in the Su-35 interim fighter. The main sensor will be a Tikhomorov NIIP X-band radar with active AESA antenna, which was unveiled at the latest MAKS Air Show in August 2009. The 1m-dia. antenna contains some 1,500 solid stat transmit/receive modules by NPP Pulsar, which places it in the same class as the F-22’s APG-77. Tikhomorov claims an exceptional range of ~400km against a 1m² equivalent radar surface target. The radar entered bench testing in November 2008, and a flyable operational prototype will be completed by mid-2010.

    In a very innovative development, the main X-band antenna will be supplemented by auxiliary L-band antennas installed in the wing inboard leading edges. In addition to the obvious IFF/SSR functions, this arrangement (which is also being offered for retrofit on the Su-27/-30 family as well as the Su-35), has a very clear anti-stealth search function. Most current stealth or semi-stealth designs – and most particularly the F-35 JSF, although not the F-22 – are optimised to reduce radar signature against X-band fire control radars as the main threat, and their low-observability features and shapings do not work as well against L-band radars. Of course, the lower the frequency the higher the wavelength the poorer the accuracy of distance and angular measurements, and thus even apart from excessive volume, weight, power and cooling requirements a fighter aircraft could not possibly rely on a main L-band system alone. However, the presence of the additional L-band antennas will provide an important early warning function against at least some low-observable targets, and it may also enable a “mini-AWACS” role. It is additionally conceivable that these antennas could also be used for the detection and disruption of sensors and digital communications systems operating in L-band, including e.g. the all-important JTIDS/MIDS/Link-16.

    While the PAK FA has no functioning radar yet, it already sports the protruding head of an electro-optic IRST system in front and to the right of the cockpit’s windscreen. This will maintain the excellent mixed solution (radar/IRST) used in all modern Russian fighters, event tough the IRST seeker’s “ball” is at odds with the search for a reduced radar signature in the front emisphere. The decision to add the L-band antennas while maintaining the IRST reinforces the perception of the T-50 being mainly intended for air defence roles against intruding low-observable strike aircraft.

    The Indian Factor

    Back in early 2007, Russia and India reached an agreement to cooperate on a Fifth Generation Fighter Aircraft (FGFA) based on the PAK FA for the Indian Air Force. The programme is officially described as involving a 50-50% split as regards both financing and R&D activities, but it is nearly universally understood to rather cover a scheme, under which India will fund a substantial portion of the PAK FA’s development bill in exchange for access to the relevant technologies.

    The Indian Air Force’s requirements do differ rather substantially from the Russian Air Force’s, and are reported to demand a twin-seat configuration as well as possibly a different wing and control surfaces. Hindustan Aeronautics Ltd is expected to become responsible for some 25% of the total development workload for the FGFA programme, involving modifying the PAK FA single-seater airframe to a twin-seater configuration as well as the mission computer, navigation system, cockpit displays and ECM dispensers. HAL will of course also take care of eventual series production of a tentatively planned total of some 200-250 aircraft.

    Indian sources have ventured into suggesting that the FGFA could be in service by 2015, but this is quite obviously not feasible given that development has not yet started. A logical date would be well into the 2020s.

    Conclusions

    As a first tentative assessment and on the basis of the basis of the scarce information as currently available, the PAK FA (T-50-1?) looks like a mix of well-proven solutions from previous Sukhoi designs married to several new ideas, in particular as regards the still superior quality of Russian aerodynamic research.

    It is also possible that the significant delay suffered in developing a Russian counterpart to the F-22 could have turned into a blessing in disguise, giving Sukhoi designers a period of reflexion to generate a well balanced design. This would relate in particular to the decision not to push for extreme low observability characteristics at the expense of everything else, including not only flight performance but also acquisition costs and most importantly maintenance requirements and thus operational availability.

    Sukhoi PAK FA comprehensive overview on defpro.com

    Part 1 of a comprehensive overview on Sukhoi’s ambitious 5th generation fighter
    http://www.defpro.com/daily/details/505/

    defpro.com | On 29 January 2010, the Sukhoi PAK-FA (Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsy, literally “Future Front line Aircraft System”), which could variously be described as a technology demonstrator, the first prototype of the future T-50 fighter, or an intermediate step between the two, took to the air for the first time from the freezing runway of Dzemgi Air Force Base (shared with the KnAAPO plant) at Komsomolsk-on-Amur in the Russian Far East Siberia (see also http://www.defpro.com/daily/details/497/). A fundamental step has at last been accomplished in the development of the long-expected Russian response to the American F-22 RAPTOR air dominance fighter.

    The aircraft, with Sukhoi test pilot Sergey Bogdan in the cockpit, remained airborne for 47 minutes, enabling an initial evaluation of its controllability, engine performance and primary systems operation, including retraction and extraction of the landing gear. “The aircraft performed excellently at all flight-test points. It is easy and comfortable to pilot”, said Sergey Bogdan.

    “Today we’ve embarked on an extensive flight test programme of the 5th generation fighter,” commented Mikhail Pogosyan, Sukhoi Company Director General. “This is a great success of both Russian science and design school. This achievement rests upon a cooperation team comprised of more than a hundred of our suppliers and strategic partners. The PAK FA programme advances Russian aeronautics together with allied industries to an entirely new technological level. These aircraft, together with upgraded 4th generation fighters will define Russian Air Force potential for the next decades.

    “Sukhoi plans to further elaborate on the PAK FA programme which will involve our Indian partners”, Mr Pogosyan added. “I am strongly convinced that our joint project will excel its Western rivals in cost-effectiveness and will not only allow strengthening the defence power of Russian and Indian Air Forces, but also gain a significant share of the world market”.

    Some Russian sources have suggested that the T-50 will enter service in 2015 (e.g. Russian 5th-generation fighter deliveries delayed until 2015), but this is but wishful thinking. Only another flyable PAK FA prototype and a ground test item exist thus far, while Sukhoi has indicated they will complete five prototypes for initial testing. These are scheduled for completion in 2011-12, with the company expecting to then produce an initial batch of pre-series aircraft for operational trials by 2015. A more credible projected IOC date for the T-50 would thus be towards the end of the decade – i.e. some 12-15 years after the F-22. Such a delay would be roughly in line when not with the scientific and technological potential of the Russian aerospace industry, then certainly with the Russian MoD’s financial muscle and the irredeemable time loss of the “black years” following the collapse of the USSR. There are persistent rumours of the PAK FA programme being largely financed directly by Sukhoi (some 75%, with the remaining 25% being provided by India), and in any case it is quite obvious that it could only progress thanks to the substantial revenues from export sales of Su-27/-30s.

    Much has already been written and speculated about this first Russian 5th combat aircraft, but virtually nothing is known for certain. The few photos and the couple of videos documenting the first flight are all that is available for a first assessment of the aircraft’s characteristics, analysing its overall external configuration and trying to deduct the Russian Air Force’s requirements on which the PAK FA design can be assumed to be tailored.

    Operational Considerations

    As expected, the twin-engine PAK FA is a large aircraft, with roughly the same physical size and weight class as the Su-27/-30 family it is aimed to replace. The aircraft’s general configuration strongly suggests a design optimised primarily for the air superiority role, even though the T-50 will almost certainly eventually go along the same road as the Su-27 and evolve into a very capable multirole fighter-bomber. This emphasis on air-to-air combat is arguably due to both the Russian Air Force perceiving its main roles in a very different way than the USAF, and the fact that the Service’s deep strike requirements are satisfactorily covered by the very capable (although admittedly not stealthy) Su-34s currently being delivered.

    Even though it is nearly automatic to think of the PAK FA/T-50 in terms of a direct confrontation vs. the F-22, and this may indeed have been the original goal when the programme was first launched in the late 1980s, in the current global strategic scenario it is perhaps more likely that the Russians are rather interested in maintaining an air superiority edge over China’s current J-11s/SU-27s/-30s and future J-12. Also, the expected future worldwide usage of the F-35 JSF attack aircraft with its low observability qualities requires an interceptor capable to deal with this peculiar threat.

    Further considerations can be done as regards the expected future place of the T-50 in the Russian Air Force’s inventory, and thus the overall combat aircraft programmes in Russia. When first information on the PAK FA project started to circulate, the programme was widely reported to be intended to replace both the Su-27 and the MiG-29, thus leading to a single-type combat aircraft fleet not unlike the French Air Force’s with its RAFALE. Whether this was purely “disinformacija”, or the Russians were actually planning in that direction back then, it is impossible to ascertain. The fact is, the T-50 given its size and expected avionics complexity will most definitely be an expensive aircraft both to procure and operate, and it is very difficult to imagine how the Russian Air Force could ever be able to acquire it in large number – not to mention the type, for all of Mr Pogosyan’s rosy forecast, having a rather limited potential export market. Current Western and unofficial Russian estimates are of a production run of some 250 aircraft for the Russian Air Force, and even this may prove to be overoptimistic. The combination of the T-50 as the spearhead of a tactical combat fleet composed largely by modernised 4th generation types, as suggested by Mr. Pogosyan, does certainly make sense – but it is rather doubtful whether it could really last for “decades”, apart from the Su-35. Also, the upgrade programmes currently underway do not involve the MiG-29.

    Hence, and although the notion of the Russian MoD and national industry being able to sustain the simultaneous development and eventual procurement of t w o different 5th generation fighters does admittedly defy imagination, the eventual launch of a programme for a smaller and less expensive “lo” fighter in a “hi/lo” mix with the T-50 looks virtually compulsory. Failing to do so would leave the Russian Air Force critically crippled in quantitative terms, and would consign the future export market for “affordable” fighter aircraft to Western and Chinese designs.

    i dont think they will cancel the A400M program now, to much has been invested in the aircraft, and the first production aircraft are already on the production line (i think).

    A good friend of mine working for Germany’s most powerful union had recently a chat with Tom Enders who said that the entire programme would be cancelled if the customer nations are not willing to pay the extra costs !!

    Boeing’s new US tanker bid strategy

    Source: http://www.defpro.com/daily/details/337/

    11:15 GMT, June 22, 2009 During the recent Paris Air Show 2009 Boeing has hit the news with a new strategy presentation for the pending US tanker bid. This new strategy is primarily based on a change of the tanker platform: Boeing is considering to give new momentum to the race for the much desired contract award by offering its larger 777 platform along with the 767 of the prior contests. This was acknowledged by Jim McNerney, CEO of Boeing, at the beginning of this year’s Paris Air Show.

    The US tanker bid, scheduling the procurement of 179 tankers worth some $35 billion to replace the aging Air Force fleet of aerial refuelling aircraft, preoccupies the aerospace industry, the political decision-makers and the media since quite a time. Back in 2001, Boeing had been awarded the first Air Force tanker contract, which was afterwards cancelled due to an acquisition scandal. In February 2008, a team of EADS and its US partner Northrop Grumman won the much discussed second contest with their A330 tanker. However, this deal was cancelled by Defense Secretary Robert Gates in late 2008 after Boeing protested the procurement process as unfair and the Government Accountability Office (GAO) decided in favour of the Seattle based company.

    Now, Gates plans to restart the process in the course of the following weeks. The request for proposals will most likely be issued by midsummer 2010 and will show up new requirements and procedures for the contest. According to UPI, the contract is expected to balloon to more than twice the initial size with fresh orders for tankers in the future. It had also been discussed in Washington and suggested by several veteran lawmakers to split the contract between Boeing and Northrop Grumman-EADS. Yet, this alternative was explicitly dismissed by Gates saying that a split contract would be “bad public policy and bad acquisition policy” as well as “a bad deal for taxpayers.”

    Bigger, better, faster?

    By offering a tanker on the basis of the commercial 777 jet, Boeing aims at improving its bidding position in view of the Airbus A330 MRTT being larger than the 767. The 777 capacity significantly surpasses the A330’s. According to Boeing’s spokesman William Barksdale the aircraft “definitely, is much more capable than the A330.” Dave Bowman, Boeing vice president of tanker programmes, confidently states: “We’re ready to build America’s next tanker in whatever configuration and to whatever requirements the [US government] desires.”

    McNerney revealed that Boeing will not leave the field to the EADS/Northrop Grumman team without a struggle. If necessary, the company’s CEO says, Boeing could develop a new aircraft from scratch which would then be available as of 2016. If the US Government will accept such long waiting periods for its new system remains to be seen. Even before, Airbus could offer its newly developed long-range A350 jet aircraft, which could be completed by 2013, according to the company.

    Boeing’s 777 could, however, encounter problems on different nature: the production of the military version could come into conflict with national security regulations. As the construction of military equipment must be conducted in secured settings, part of the production of the commercial and military aircraft would need to be carried out in separated buildings. Furthermore, according to different sources, several defence specialists doubt that Boeing will be able to redesign the project in such a short term.

    Also at the Paris Air Show, Northrop Grumman and EADS reaffirmed their commitment to the KC-45 tanker. In a joint statement Ronald D. Sugar, chairman and CEO of Northrop Grumman and Louis Gallois, CEO of EADS said: “The KC-45 was previously selected because of its superior operational capability, lower risk and greater cost competitiveness. We have continued to strengthen our offering and look forward to working closely with the U.S. Department of Defense and U.S. Air Force to ensure that the upcoming competition will provide the warfighter with the most capable, best value tanker available.” (see: http://www.defpro.com/news/details/8114/)

    Boeing Committed to Funding F-15 Silent Eagle Development

    Source: http://www.defpro.com/news/details/8167/

    09:15 GMT, June 18, 2009 PARIS | The Boeing Company [NYSE: BA] will dedicate funding to further development of the F-15 Silent Eagle program, with the goal of a flight demonstration in the third quarter of 2010. The announcement came at the Paris Air Show following meetings with potential customers and reaffirmed a commitment to the prototype program made by Boeing Integrated Defense Systems President and CEO Jim Albaugh at the air show on June 14.

    The F-15 Silent Eagle, which Boeing launched in March, advances the most modern variants of the F-15 multi-role strike fighter with enhanced survivability. Features include a digital electronic warfare suite coupled to an Advanced Electronically Scanned Array radar for enhanced situational awareness, aerodynamic improvements and cost-effective radar cross-section reduction technologies.

    “We know from talking with current international F-15 operators that they are very interested in the capabilities of the Silent Eagle,” said Albaugh. “Making this commitment to get the program through to a flight demonstration will ultimately help international customers understand how this aircraft meets their need for a flexible, long-range, large-payload, high-speed, multi-role strike fighter with reduced observability.”

    Boeing will conduct further trade studies to allow new F-15 technologies to be brought to market. In addition, Boeing will continue discussions with a number of international aerospace companies about potential co-development opportunities.

    House Committee votes to include $369 million for the advance procurement of 12 F-22A’s

    defpro.com | 06:06 GMT, June 18, 2009 Surprise, surprise! The House Armed Services Committee yesterday morning voted to include $369 million in extra funding to the Pentagon’s 2010 budget for the advance procurement of 12 F-22A fighter jets. With an extremely close vote of 31 to 30, the House committee chose to increase the Raptor inventory and, thus, to ensure continued production of the stealth fleet beyond 187 aircraft. The $369 million is just the financial base for the procurement of items and materials needed for one dozen aircraft, which is now expected to be authorized in Fiscal 2011.

    This move was somewhat unexpected, since Defense Secretary Robert Gates proposed phasing out production of the US Air Force’s most expensive fighter, the Lockheed Martin-built F-22 Raptor, by fiscal year 2011. Gates believes the Air Force only needs 187 F-22 fighters. “We will end production of the F-22 fighter at 187 – representing 183 planes plus four recommended for inclusion in the FY 2009 supplemental,” he said in early April, and observers thought the Raptor was dead. Gates proposed, in the 2010 Defense Department budget, to boost the F-35 Joint Strike Fighter (JSF) instead.

    The committee proposal, which now will have to wind its way through the House and Senate, is sure to come under scrutiny from the White House. Both Gates and President Obama do not want funding for a new fighter in the 2010 budget. The additional hundreds of millions of dollars will go against plans to rebalance the US military’s spending.

    One lawmaker told The Wall Street Journal that 187 jets is “frighteningly low”. Some lawmakers wanted to commit to purchasing 12 more F-22 jets, but others in the group thought that option would be too expensive. The new funding is, in effect, a down payment on 12 additional jets to be bought in fiscal year 2011.

    The 199 fighters still dips well below the 381 F-22s that the Air Force has always claimed it needs, and far short, even, of the 243 fighters set as the new military requirement by the USAF Chief of Staff, Gen. Norton Schwartz.

    In a statement, Lockheed said it “remains confident that the Congressional review process will lead to a healthy and full examination of budgetary and economic impacts, strategy, force structure and threats.”

    It added that, as the Pentagon’s largest contractor, Lockheed “will continue to support our customers and work to deliver affordable solutions that meet their strategic and operational needs.”

    After the VH-71 termination – What’s next?

    06:27 GMT, June 11, defpro.com | 2009 On January 23, 2009, President Obama stated that the VH-71 presidential helicopter programme was “an example of the procurement process gone amok.” In fact, the VH-71 programme has experienced significant schedule delays. US Defense Secretary Robert Gates said April 6 that the programme has fallen six years behind schedule and runs the risk of not delivering the requested capability. He recommended the president to terminate the programme which has seen already more than $3 billion invested to cover the R&D and production costs of the first phase.

    As a result, Ashton Carter, the DOD acquisition executive, issued an internal DOD memorandum directing that the VH-71 programme be cancelled on May 15, 2009. The Navy announced a stop-work order and a termination of the programme on June 1.

    Since the termination of the VH-71 programme, which had the aim to provide 23 new helicopters replacing the 19 aging VH-3D and VH-60N rotorcraft used to transport the president, the US Congress has now to approve the Administration’s proposal and initiate a successor programme.

    According to a report by the Congressional Research Service (CRS) released on June 5, CRS is exploring the costs of alternatives to canceling the VH-71 presidential helicopter programme. In this report the CRS stated that continuing with the VH-71 programme in more or less the current form would result in acquisition costs of $13 billion or more, including sunk costs on the VH-71 programme of more than $3 billion bill, thus taxpayers would have to pay about $10 billion.

    Since its beginning, the programme was divided into Increment I and Increment II helicopters. The Increment I meet some but not all the operational requirements as stated in the VH-71 Operational Requirements Document which was approved by the DOD In December 2003. It was intended that the Increment I enter service first as near-term replacements while Increment II which meet all the requirements in the ORD, were to enter service later.

    An alternative proposed by the CRS would see 18 Increment I aircraft procured while Increment II would be cancelled. Including the five pilot production Increment I aircraft, this would make a total fleet of 23 presidential helicopters. Terminating the Increment II would save $3.6 billion leaving less than $6.4 billion to taxpayers, the report stated. Another option could see 14 rather than 18 additional Increment I aircraft procured saving another hundreds of millions of dollars.

    This estimate of both proposals, however, does not include the costs of keeping the 19 existing presidential helicopters in operation until they are replaced by the new aircraft.

    Alternatively the 19 existing presidential helicopters could be upgraded and their service lives extended. Such an upgrade could cost $4.4 billion according to US Navy estimates. According to the CRS an upgrade could extend the service life of the VH-60Ns from 10 000 to 12 000 flight hours and thus provide another 6.9 years in operation. The VH-3Ds would have their service lives extended from 14 000 hours to 16 000 hours, providing another 6.7 years of operation. However, the 19 existing aircraft would not meet many of the operational requirements in the VH-71 ORD.

    Be this as it may, due to the advanced age and technological limitations of the current fleet, a new fleet of presidential helicopters are still necessary. The proposed live extension of the current fleet of presidential helicopters, which are already 35 years old, would just postpone the date for a new programme which still will be needed. The US Congress has now to find out if a total termination of the programme would be even more costly than completing the current program under one of the above mentioned option.

    Lockheed Martin Systems Integration-Owego is the prime contractor and systems integrator for the VH-71 programme with overall responsibility for the programme and aircraft system. AgustaWestland, the principal subcontractor, has responsibility for the basic air vehicle design, production build, and basic air vehicle support functions.
