    The Iraqi air force was stuck in a pretty hopeless situation.

    If anyone has played a good combat flight sim like LockOn, which attempts to model the functions of radar, AWACS and EWR what you see demonstrated are the standard operational doctrines of force coordination. The fighters don’t even use their own radar to view the combat field, but have target information relayed by datalink from AWACS or EWR. Lose AWACS/EWR and pilot view diminishes to a small area around individual aircraft who then have to work together for field coverage and rely on the power and complexity of their onboard sets, prone to electronic warfare and certain technologies and techniques, conditions, failures, etc.

    Contrary to popular western belief Soviet aerial doctrine specified a defensive war rather than aggressive warfare, according to the Kremlin and supported by aircraft fit as compared to western contemporaries.
    Put simply the radar sets on Russian fighters isn’t so good. Losing EWR is catastrophic, the Luftwaffe published their Fulcrums were not suitable for front line service with a NATO air force, was entirely dependent upon EWR systems and poorly suited to independent operations, due to its poor radar and navigational system, both are unreliable and can barely perform their advertised functions, they don’t even have modern radios installed. None of this makes the slightest difference operating under an effective EWR network, which is how they’re designed to operate.

    Saddam didn’t want to lose his Fulcrums but lost his simple EWR system in the first days. He sent them over to Iran on an agreement he would get them back when it was over, if the country was still independent. Iran agreed because they probably realised that wasn’t going to happen.

    This kind of electronic warfare is something NATO/USAF are specifically tasked with making a priority in any conflict, attacking EWR, ECM and SAM sites in the very first wave of any assault into enemy airspace. Among the highest priority is enemy radar networks.
    Takes the teeth out of a modern air force, unless it has AWACS or well fortified ground control/radar stations in reserve (eg. a command ship in nearby harbour, like those new Russian battlecruisers can improvise as an aerial command/control station).

    In my rush I forget to specify composite/honeycomb as opposed to stressed alloys.
    Still, for the F-15 a titanium ribbed al-alloy torque box, al-honeycomb wing tips, flaps and ailerons, titanium airbrake panel, graphite/epoxy skin with honeycomb sections.
    F-16 is an alloys fuselage/wing with al-honeycomb leading edge flaps and components, meagre titanium reinforcement, fin is epoxy skinned, tailerons are epoxy/resin skinned with al-honeycomb leading edge, ventral fins al-honeycomb and stressed skin.
    Hornet is mostly epoxy/resin skinned al-honeycomb and alloys throughout with a titanium engine firewall.

    The Tomcat is stressed alloy skinned over titanium sparring/components and most closely resembles Flanker structure of the US contemporaries. Flanker is specified by Sukhoi OKB as all metal with no composites at all, and it doesn’t use honeycomb. Actually a Janes writeup has it as semi-monocoque with mostly titanium components, citing Sukhoi as a source.

    The Fulcrum is like a cross between the Foxbat/Foxhound and an F-16, having the simple steel fuselage box with other components of various alloys, composites and a novel carbonfibre honeycomb vertical tails. It’s like a lovechild.

    Göring’s zerstörer doctrine was actually a feasible tactic that was killed by radar and since he’d been in the unfortunate position to dictate Luftwaffe outlay specifically to suit this requirement, my pet theory is that it was a telling factor of the BoB deteriorating almost immediately into a war of attrition (something the Wehrmacht as a whole was specifically tasked with avoiding at all costs).

    Not many people understand what the zerstörer concept really entailed but it was an entire battlefield strategy that worked superbly in France and then again (with revision) on the Eastern Front until late-42. Didn’t work so good in North Africa by circumstance and failed miserably in the BoB, due to radar (in Poland there weren’t many Me-110 units equipped and most ZG staffeln fielded the 109D).

    Central to the strategy was the Me-110 which was not ever intended as assumed as an escort fighter, though it was improvised for this purpose from Norwegian bases in north Britain attacks.
    What Göring stipulated to his subordinates, of which he was utterly convinced was genius to rival Hitler himself, was the use of medium range attack aircraft as heavy fighters. His idea was that these heavy fighters would accelerate ahead of the bomber stream and whilst enemy spotters were marking bomber positions and relaying them for interception sorties, the Me-110 were diving on airfields in advance and destroying them running up on the field with cannon fire. A force of these attack-fighters would hardly be noticed with the bombers and tracking efforts would concentrate on the strategic threat.
    As mentioned this worked extremely well in France, the relatively dispoportionate number of combat ready interceptors were frequently strafed on the field by Me-110 whilst they were still getting updates on bomber positions, and were out of range of both 109 or stuka attacks, the traditional continental tactical force.
    The contemporary of the Me-110 in this light is really the Blenheim or Fairey Battle, where even the Boulton Paul Defiant is a different design requirement.

    But quite clearly radar tosses this midwar tactical genius to the wolves and it doesn’t stand up to atypical air defences/equip by midwar period (it was attempted to rehash the strategy using a specialised Ta-152 variant to enter production 1945, but otherwise the ZG wound up becoming schnellbomber units).

    The thing was the poor German scientists didn’t believe small wavelength radar was achievable by any nation well into the war (even when an RAF heavy was shot down with a 10cm AI radar on its belly they resisted that it was genuine), and so they vastly underestimated British radar development (in its ability to be pivotal in air defence), the potential of the system and the value of centralised RAF district command. Their doctrine remained AAA and independent organisation as the primary defence strategy, with only rudimentary radar development until later in the war. German radar could pick a ship out on open water but an aerial flight near a coastline starts to get dicey and this was what they assumed the common standard.

    So died the zerstörer concept. Me-110 may have been attributed with some very damaging results on the RAF otherwise.

    In a video taped interview Günther Räll specifically talked about the leading edge slat problem in turns with the Emil, and said it brought inexperienced pilots unstuck. This was the kind of turn so tight that one is rolling flaps. Most inexperienced Emil pilots didn’t enhance the turn by rolling flaps, possibly for this reason. He did, but he said it gave him a nasty shock and it was his experience on control feel and a cool head that saved him from a snap stall.
    Normally a stall with the Emil was extremely predictable, moreso than contemporaries but this issue was the exception to that rule.
    Other sources explained this issue was fixed from the F series wing redesign, a new rail system for the leading edge flaps were installed and I’ve never heard this problem described for any later version Messer.

    Instead they had a problem about pancaking on the runway because of 605 installation being entirely overpowered for the original airframe design specifications (torque progression is too sudden off idle), so accident rates among cadets within 1km of the home airfield reduced with later model airframe refinement but cadet fatalities in the G series onwards actually increased on the runway itself, so almost comically were overall unaffected. If the type was in Allied service it would’ve been nicknamed widowmaker, but aces loved the type and it really handled very nicely at high speed.

    I tend to think such opposite extremes of traditional populisms (the Spit won the BoB, the Mustang was the best fighter of the war, etc.), are really an intentional counterpoint attempt to level out those populisms with the opposite extreme, between the two the idea is the general public finds a balance and declares them equally contemporary types.

    A family member flew the 109F/G/K from Africa to German airspace and had quite a few things to say about their comparative performance, which at the time challenged popular books directly. Much more recently many of the things he mentioned in my childhood have been since reviewed and confirmed.
    He also liked the F series best of all, but said for out and out performance the G-10/K could go toe to toe with a Mustang, but such statements are always conditional and in this case was a response to a book I brought home from school that said the late war Messer was useless and the Mustang far superior. But half the time these books don’t even have the variant specifications correct, there’s like 6 major engine/equipment layouts in the G-14 series and all late war Messers vary dramatically by where they were produced, things got a little crazy there towards the end.

    There have been several serious evaluations written about the BoB spec Emil and Spit and I’ve watched most every veteran interview on record (had a great DVD that featured most surviving fighter vets from all theatres in interviews and seminars), the overwhelming conclusion is that they were both perfectly contemporary birds.

    The most important point to recognise about them is the oft forgotten fact that they fly completely differently. The same piloting technique which works beautifully in a Spit will get you killed in the Messer, and vice versa. They have very different fingerprints of the performance envelope, very different engine operating characteristics, but totalled they make contemporary, but different short range fighters.

    The Messer has a very powerful cruise condition, the Merlin needs to be run up to the high speed condition, so bounce acceleration from cruise to high speed is virtually instantaneous in a Messer and takes a few adjustments and a couple of long seconds in the Spit. This characterises the Emil as having great acceleration.

    Sustained climb was always terrific in the Messer, throughout the war. It’s a great torque producer and has the hydraulic blower which is similar to a mild two-speed setup without as sharp a drop off mid range.

    The Daimler still pulls nicely above 6000m when the single step Merlins are already dropping off, Räll said frei jäger often cruised at 7000 metres in the combat zone for this reason and had good success with it (killed by the close escort doctrine as it was one of the greater Emil strengths).

    A good pilot can roll the fully variable Emil flaps for combat use to increase turn rates in a pinch, bringing them to Spit territory but there was another problem in the mechanics of the leading edge slats which made one occasionally extend in a tight turn without the other, which caused snap instability unless the pilot was experienced enough to recover and re-enter the turn on control feel. This was fixed in the F series production.

    The Messer suffered from a ridiculously tight cockpit out of tune with its long throw stick, poor vision anywhere but forward or forward/down but had great ergonomics, very good equipment and handled very predictably and capably at speed. The Spit had much better room, poorer ergonomics and terrible view front/down but nice stick movement. It was best mid range and had much better low speed handling. Marsielle actually said the most important thing for any Messer pilot to learn if he wanted to become an ace was handling the 109 at low speed, under 300km/h IAS it was outright dangerous where the Spit was still flying beautifully. This combined with narrow track gear for the silly accident rate of Messers, where the Spit service record wasn’t affected quite so badly by the narrow track gear.

    There’s a lot of specific points between the two types defining their markedly different character and piloting techniques, but ultimately they are performance contemporary and compare very well overall.

    According to Galland and production references some 800 airframes were built, however with engines and spares for no more than 200 at one time, at most.
    IIRC they ran on kerosine, which is a fuel bonus somewhat but I know various sources cite the Allied bombing effort was definitely telling here.

    Also the Meteor FMk1 had a top speed around 415mph and the F3 (prior to nacelle modification) at 490mph giving the Me-262 a speed performance edge. Late series F3 though which might’ve reached the front in the second half of 1945 had a sea level speed of some 415mph but then other German models such as the Horton/Gotha 229 and the high speed Me-262 modification would have to be considered in such a historical-fantasy setting of continuing conflict against an existing German war machine.
    Meteor squadrons sent to Europe began upgrading from the Mk1 to the early F3 in Jan45.

    IIRC in early45 two squadrons of P-80A were sent to Italy for service evaluation and flew sorties in the combat zone, though no enemy aircraft were encountered. IMHO this aircraft is a better match for the 262 but wouldn’t have been in front line service in numbers for some months and has that turbine problem in early production.

    The writing was on the wall for Germany, clearly to all the Allied leaders (and OKH) by early 1943. By early 45 the wind down was already in progress, hence the shock about the Ardennes offensive, Baseplate, even Lake Balaton (in terms of aerial complement), and continued resistance over Bavaria (put up a nice show against bombers there). Already by this time, according to records Churchill and his contemporaries across the Atlantic were discussing the postwar Soviet environment in western Europe, talks that started in mid-43.
    Between Torch, Bagration and Normandy, Germany was simply done for and those offensives were planned well in advance (Normandy was originally mooted with mid-43 in mind but it was too soon for such a big operation and the weather would’ve turned before preparations could be made).
    About the only people who were so insane they didn’t know the war was over by roughly Feb43 were the most fanatical Nazi party members, not their military commanders nor even their waffen field commanders weren’t well aware of it. Word is Rommel envisioned Allied invasion of western Europe with overwhelming air superiority by the time he left Africa, so was put in charge of the west wall by Hitler despite his blemished record. At home the loonies were living in some kind of crazed bohemian fantasy characterised beautifully in the German film Downfall.

    Russian sentiment is (rightly) that US defence journalist concerns about Iran and North Korea are nothing more than a proxy of continued strategic concerns about the CIS and China. USAF bases in Bulgaria, munitions stockpiling in Romania, and NATO presence in Afghanistan really aren’t helping.

    Only in the Star Trek universe does Iran or North Korea conceivably threaten anyone further afield than immediate neighbours in any forseeable future. This point is punctuated by their stoic, isolationalist political cultures. What they are is paranoid, not territorial. So the inherent question is what policies are the US tabling to warrant any possible concerns?

    And this is the inherent question of the CIS and China, being any significant expenditure on BMD systems are plainly aimed at they with any other excuse nothing more than a proxy for benefit of political correctness in the eyes of the general public.
    So what policies exactly are the US tabling to warrant such fears of international aggression by other major powers?

    This is basic stuff. Bush was trying to start the Cold War over again and doing to get at the Caspian table. It would’ve been disastrous, and Obama has a far more level head.
    Hopefully he’ll withdraw the USAF Bulgarian bases and Romanian stockpiles because presently that’s a great big slap in the face of the Black Sea region indigenous security protocols and the general national security of Russia.

    The Watts two-blade fixed pitch was early production standard, I’m not sure the timescale but fairly early on the De Havilland variable pitch (two settings, three blade) was standard factory equipment through to about June 1940 for the MkI Spit, and was retrofitted to Hurricanes (only those in France still had Watts). By Dunkirk pretty much the entire RAF home fighter force had De Havilland.
    From June 1940 the Rotol (hydraulic) constant speed was introduced for production of MkII Spits and retrofitted to MkI. It’s a manual constant speed (ie. fully variable with incidence limiter) with about 35-deg travel.
    The Hamilton Standard is electric and less prone to overspeeding in dives; iirc fitted from the MkV but a Spit expert would have to elaborate/correct as I’m running on a distant memory with that.

    Oops yes MiG-9, it was a typo. MiG this, Yak that, you know how it can be 😛

    From my understanding they were handed over in large numbers to China and some wound up in NK hands during the early stages. Some early US aerial kills are MiG-9 and Yak-9P and Yak-15 are both listed as types used by the NKAF with sources such as Wright-Patterson (only the Yak-9 piston engine aircraft was comparatively tested but various sites mention both Yak-15/17 and MiG-9 in passing).
    Anecdotal at this stage I realise, since I haven’t been researching the Korean War specifically, lately or anything, just running on memory but it shouldn’t be hard to check.

    Also the P/F-80 was very successful, but early series production engines for the A had a manufacturing issue with the turbine blades which caused several catastrophic accidents, some fatal. It wasn’t recognised until one pilot survived and explained how the tail section had sheared off mid-flight, which led investigators to turbine failure, then they found the manufacturing plant was using substandard procedure affixing turbing blades. It was fixed, but nobody knew about it in early 1945 and if in general service that year as a major front line type there would’ve been a lot of problems over this, for one the fleet would’ve been grounded just as it got up to number.

    I’ve been looking over Russian navy equip lately and have to say I’m impressed, their kynshal/kashtan and navalised S300 AD systems are better than anything currently equipped in the USN (not talking about proposals and upgrade programs, just what’s on the water right this minute). Also their emphasis is clearly surface action, tailor made to counter the US/NATO doctrine of force projection. That kynshal can point defence on high Mach missile attacks from better than 20km guaranteed, which is a threat capability NATO doesn’t even have at the moment (tomahawks are subsonic, etc.). And there is no doubt the S400 is being navalised.

    That’s an aside, from a tourist.

    My impressions of the Tomcat/Pheonix system are a characterisation of technological age. I think they were safely retired because of the modern capability of weapons systems to develop into air intercept weapons able to lock small, high Mach threats which are highly manoeuvrable “intelligent weapons”

    Given back in the 80’s the Phalanx was the only point defence system really capable of defeating many Russian high Mach anti-shipping missiles and most of those are nuclear capable anyway (and 650-1000kg shaped warheads even if conventional), the 2km defence zone for the carrier even among pickets isn’t really adequate and older generation SM-1/2 or SeaSparrow can’t really do this job assuredly.
    Using a little detective work we can look at the Pheonix system and its design feature of missile interception. Put that together with a ca.120km CAP and standoff range of around 120km on Russian ALCM antiship birds, and what you have is a dedicated fleet defence aerial SAM site on picket from the carrier, performing both intercept and point defence functions (shooting down enemy missiles).

    So the point would be current generation shipboard AD networks are capable of performing the point defence function largely themselves, which means you just need really good aircraft interceptors on CAP now, which you can do with SuperHornets and AMRAAMs perfectly well. You might increase CAP to something like 150-180km in a high threat environment and sit your pickets 20-50km from the carrier (close enough to be protected but far enough to help), sending a cruiser force ahead if a serious surface action threat presents. This would appear to be current doctrine, working from tech outlay.

    @ Scorpion, agreed but I do hold reservations about technology demonstrators and marketing proposals being regarded as front line service aircraft for comparative purposes. There is no current plans to upgrade the RuAF MiG fleet, though the suggestion has been tossed back and forth for years, at this point it is still deferred for Flanker upgrades and left in the air. India appears the only operator even interested in keeping their fleet in the air. This is current.

    The Fulcrum structure is by weight around 65% aluminium-alloys on the airfoils and the rest composites with a steel fuselage box (for ease of production).
    By comparison the Flanker is mostly titanium structure with alloys and no composites (a roughly similar airframe construction to the Tomcat probably with similar tolerances). Thus the bulk of the production cost of a Flanker as compared to the MiG is the titanium, the industrial use of which the Russians had come a very long way in the 80’s.
    Titanium isn’t really better than aircraft quality metal alloys at normal speeds (through to 2.5M), but the bonus is it’s much much lighter so the Flanker ca.22 ton take off weight is deceiving for its size and complexity as an air superiority style type, returning the extremely impressive ca.120kg/kN power loading (helps that awesome low speed handling).

    The newer proposals from Sukhoi (from 35S to Berkut and Pak) are listed by the company as up to 70% titanium structure. You might think of it as the way US “teen fighters” have composites as their defining feature, in the same way the Flanker is defined by a titanium structure (awesome time to altitude rates, etc.). Composites do give different characteristics however (better integrity but less flex), so mostly composite structures like the popular US fighters are noted for extremely high g manoeuvres in thick air at any speed, the relatively high alloys/titanium content of the Russian fighters by comparison perform equally well under most conditions, are better suited to high Mach operation (an emphasis probably gained from their 60-70’s design doctrine and thus production/operator experience), but for the Fulcrum the main emphasis is production ease and for the Flanker it is time to altitude and other balls out performance marques.

    Hey I love the Fulcrum, it’s a great aircraft. I just don’t think it is suited to the mission doctrine of US export fighters and is better suited to a large air force with a licensed plant and dedicated infrastructure supporting their service life and maintenance. India can probably pull this off better than anyone, so for them the Fulcrum is a great, deadly fighter, in any FBW form it’s contemporary with western models under those support conditions, albeit savings in outlay is offset by operational costs totalled.

    I also love the Flogger-K, that Russian-only final MiG-23 variant could out-accelerate any F-16 block in service at the time did you know? It’s one of the few fighters which routinely achieved advertised performance in service, loaded which makes it almost a Mach faster than just about anything else around.
    If there’s one thing the Russians do well it’s upper envelope performance in the field.

    Myself, I voted for Flankers for the RAAF over JSF/SuperHornet. I think some MKI spec Su-27/30 would’ve been perfect for us, except the conversion for our semi-NATO role and certain associated details were prohibitive. One of the most important things about using RuAF models is they are awesome and contemporary aircraft but only if you use them like the Russians do, which is how they were designed to be used. Using them in NATO doctrine takes away some of their benefits, and puts them against aircraft that were specifically designed to make use of NATO doctrine. It’s an administrative effort to stack the cards against yourself.

    Up to you fellers, but I’d prefer discussion without itemised quoting, as I can scroll back over my own messages if I suddenly turn senile and it seems less like trolling and more like independent discussion without itemised quoting.

    This way we can separate those individuals who just marque point by point what someone said and argue with that, instead of having some opinion/discussion about what they were referring to/talking about, which is more like mature discussion.

    I quite like a discussion forum but got the sudden impression I might’ve signed onto a troll forum, I hope I’m wrong since it’s such a common thing on the web it’s not even interesting anymore.

    Okay, yes above I was talking about Fulcrum engines and typo’d Flanker. The RD-33 have a design issue, as someone mentioned this is a matter of give and take. Essentially in the class of the F404 it has a neat afterburner setup (which would be the reason for its rather unusual looking nozzle), in augumentation however it goes through fuel like a sieve. It’s also the cause of very high temperatures aft of the chamber and as mentioned according to flight mechanic description (a Rumanian iirc), TBO really meant scrapping unless you had a lot of new parts from a consistent Russian supplier, placing the RD-33 (those in current service) at least among export operators in the class of updated Foxbats in terms of operational service life with little expenditure. The Luftwaffe hot-end kit increases TBO from 800 to 1200hrs but this is in conjuction with detuning to 404GE-402 class. Overall design engine life is around 2000hrs before replacement.
    The RD-33K squeezes roughly 4% thrust increase with a higher airflow and associated increased entry temp, it’s going to have a lower overall service life than the standard engine (I’m surprised the TBO is the same).

    Once again the German kit was built by an operator accustomed to NATO export models which are meant to last in the field with only periodic update packages and general maintenance routines. The Fulcrum design reflected in its engines is meant for advance bases of a major power with an active support infrastructure and high maintenance routines. It was never designed with export in mind, it was designed for home use by the Cold War USSR. This means you could afford to take compromises to return a higher augumented thrust proportionate to dry operation than comparable engines in service elsewhere.

    Also the engine design itself is optimised for medium alt over low alt best operation, where Hornets/Vipers perform exceptionally at low alt. In western terms the problem here is that right at the altitude the Fulcrum starts coming into its own, it walks into the realm of the Flanker anyway.
    Truth be told however the VVS/PVO/AV-MF was never set up that way and Fulcrums wouldn’t often be in the same combat area as Flankers. More recently things are increasingly centralised in Russia/CIS (journalists call it “becoming NATO-ised”), but that wasn’t the case when the Fulcrum/RD-33 was designed.
    Trying to convert the Fulcrum into a hi-lo coordinated deployment equivalent to the Viper/Eagle is an ad hoc adaptation for which the inherent design isn’t really well suited, whilst completely redesigning the equipment installation for the type as the SMT/K/whatever isn’t quite as good an option of either putting a whole new type in production using different engine/airframe combination or just purchasing some Block 50 Vipers. In any case I don’t think we’re going to see any operator of the Fulcrum using it in the hi-lo USAF air combat doctrine.
    So a mid range all rounder is what it is. Not quite as good as a Viper on the deck, shouldn’t try to mimic an Eagle on the deck, but equal or superior to most at medium altitude, and then inferior to dedicated air superiority aircraft like the Flanker or Eagle at high altitudes. Most of the time it does okay, but it’s not meant for the hi-lo Viper/Eagle type of doctrine in conjunction with Flankers, it’s meant for independent operation well within an EWR network, over short ranges from advance bases.

    Upgrades in proposal stage and phantom variants or concept demonstrators I have no interest in unless we want to start talking about the Aurora x-plane and lightsabres or whatever. A good upgrade for the Fulcrum-C fleet, aside from full FBW integration would be a completely different engine option with much better efficiency and service life potential (I’ll call western experience with Fulcrums “potential” because it departs MAPO marketing claims), but this would mean of course less performance. Kind of like the German attempt to make the RD-33 give a decent service life without a consuming parts like a trash compactor.

    The IAF Fulcrum fleet serviceability rate is universally recognised as poor whilst the German Fulcrums managed only 50% serviceability for the year 1992 when the aircraft equipped were only five years old. The IAF also reported double the projected accident rate according to MAPO for the year 1992 (often due to engine failure, despite common belief the Fulcrum is not at all easily flyable on one engine), again with individual aircraft only five years old at most. Serviceability and accident rates (due to engine failure) have remarkable similarity throughout Fulcrum operators, all understated by at least 50% in MiG-MAPO marketing claims.

    As for my citing Flanker expense, it’s made out of something like 65% titanium, in what universe is a Flanker not inherently expensive? It is cheaper than US contemporaries but is less sophisticated. Again I’m not interested in phantom variants, speaking in terms of anything actually put in service. IAF Su-30MKI is less sophisticated overall than USAF F-22A, its contemporary; Su-27S is less sophisticated than F-15C, its contemporary. The Flankers have awesome airframe performance aspects though. In any case they are not inexpensive aircraft to purchase or produce, despite being cheaper than the model contemporary flyaway price in the US (who also have cost recovery agendas to consider, hard to believe but I think they rip people off a little like car salesmen).

    As Scorpion suggested, there are so very many Flanker variant proposals, revisions of proposals, and proposals of proposals that it is easiest to view simply the ones in service and consider them the existing variants, rather thinking of the “no-suffix” and M/MK, MKI, MKK, MKM as like A, B, C-1, C-2, C-3 variants etc. The layout of the current upgrade being paid for by the RuAF is closest to the MKK afaik and it’s a nice way to describe what it is, despite Sukhoi listings the twice revised M2 (M2 plus second ammendment, post-development, preproduction series 2b but only at the KnAAPO plant and series 1-3616 at Irtrusk or whatever this particular Su-30M update is fully labelled) has optional vectoring thrust and normally-shipboard-gigantonormous cruise missile capability, well if those things were actually ordered and were going to be installed.
    It has optional laser guns and proposed little green men.

    It’s an MKK for the RuAF as the simplest way to describe the upgrade, from what I can tell, or that is as Scorpion said the MK2 evolution of the MKK which is an MK for China (K) in the second revision MK2 to bring parity for older Russian service models with current exports MK, making it a revision of the M and thus an M2, most closely resembling the equipment/layout of the MKK in the second revision (excepting only transponder codes afaik).

    In other words I’d like to send Sukhoi OKB to the Gulags for being pointlessly confusing.

    The nose directional authority of the Fulcrum is little more than a roundabout way of talking about the “stability enhancement override” the MiG has because of its limited flight control interpretation, which FBW systems do not have. The automatic AoA limiter virtually all modern warplanes have can be overridden in the MiG by essentially switching off the limited flight control system it has, which isn’t a fatal thing to do unlike most FBW modern aircraft (the sole exception would be the Mirage 2000, which is also still flyable without a control system just not particularly nice).
    This ability to make the plane do what you want it to despite the flight computer, in terms of sustaining AoA is certainly quite some nose authority to have.

    It’s not the same thing as sustained manoeuvrability, turn capabilities by speed, acceleration and speed performance by altitude. Compared to even the Block 40 F-16 (considered the Fulcrum’s main contemporary by production timescales) the MiG loses momentum in sustained manoeuvres, can’t keep up in acceleration or speed at low altitude (unless F-16 has PW engine prior to block 52) and can’t match its turn capabilities above 0.85 Mach clean.
    It is also far more restricted by external tankage especially in the Fulcrum-A (which can’t even fire the gun with a centreline tank unless modified by the Germans but the 9-13 fixes this). This is very bad news because its range is so bad unless cruise performance is constantly maintained.

    Here’s a nice review posted directly to the internet at F-16.net by the author (instructor at USAF fighter weapons school) and reposted by another member. Scroll to four posts down.

    I also have a hard copy of Köck’s evaluation given to Jon Lake in interview.
    The cited problems with the Fulcrum include:

    …navigation system is unreliable without TACAN updates and is not very accurate (I’d prefer to call it an estimation system). It requires triangulation from three TACAN stations and if you lose one you effectively lose the system. We can only enter three fixed waypoints, which is inadequate. For communications we have only one VHF/UHF radio.
    The radar is at least a generation behind AN/APG-65…it has poor displays, giving poor situational awareness and this is complicated by the cockpit ergonomics. The radar has reliability problems and lookdown/shootdown problems. There is poor discrimination between targets and we can’t lock onto a target in trail, only in lead.

    Naturally Köck has a better review of the Fulcrum’s dogfight capabilities, although as I’ve said this is a parity with modern western fighters and not a superiority without the Archer/HMTD system in conjunction with EOS (IRST, which has better target track/lock than the radar). It was this novel weapon/helmet-sight and the electro-optical IRST that made the Fulcrum “unbeatable” inside of 2 miles, not the airframe performance which is a parity and has some marked design limitations modern western fighters don’t.

    But when all is said and done the MiG-29 is a superb fighter for close-combat, even compared with aircraft like the F-15, F-16 and F/A-18. This is due to the aircraft’s superb aerodynamics and helmet mounted sight. Inside ten nautical miles I’m hard to beat, and with the IRST, helmet mounted sight and Archer I can’t be beaten. Period. Even against the latest Block 50 F-16 the MiG-29 is virtually invulnerable in the close in scenario. On one occasion I remember the F-16s did score some kills eventually, but only after taking 18 Archers. We didn’t operate “kill removal” since they’d have got no training value, we killed them too quickly.

    Yet at the same time we have an experienced Eagle, Viper and Fulcrum pilot with the USAF explaining the Eagle for example can sustain a better high g turn at low alt if the MiG makes the mistake of trying to mirror his moves. However the same scenario at medium alt is reversed and the MiG is more agile in thin air.

    So keeping in mind the Viper/Hornet are optimised for low alt high performance, the Fulcrum by comparison is obviously meant to bridge the gap between the hi-lo USAF/NATO doctrine of matching larger numbers of Vipers with smaller numbers of Eagles. The Fulcrum would be typically used in the combat zone without the presence of the Flanker, so has to combat both these types. And the Soviet approach to this was numerical superiority at the cost of complexity and high all round performance at the cost of longevity, being overall a most importantly affordable package which is relatively easy to produce.

    These kind of design requirements aren’t that of a NATO export fighter like the F-16 or Hornet, where sophistication is thought of as lethality, whilst affordability is measured in terms of air superiority models and ease of production isn’t really much of an issue. Meanwhile design life and individual airframe/equipment longevity is a primary requirement, most particularly for the export market. In fact the LFX and Navy’s Phantom replacement project both stipulated export suitability and sustained independent operations (longevity) in the engineering requirements.

    The Flanker design approaches these requirements far closer than the Fulcrum, which isn’t really in the same class. It’s a very specialised Cold War general fighter, with very short range, low serviceability and a limited service life.

    I read a description of operational Yak-17UTI aircraft which remained in service from 1948 into 1960’s and had Soviet remanufactured Jumo 004B motors (RD-10). They were unchanged aside from improved materials and this trainer was noted in particular for its reliability, both this reason and its usefulness of converting pilots from piston to jet (it’s a Yak-3 with a jet motor strapped to it) were behind it continuing in service for so long.

    The other early Russian jet which was highly respected was the Yak-9 which by the Korean War was only just being replaced by the MiG-15 in Soviet use but was given to the Chinese in large numbers, thus operated by North Korea initially. These used twin remanufactured BMW-003 (RD-20) and again were noted not just for their manoeuvrability, but excellent reliability despite a problem with the NS-37 gun mounting.

    By the same token there was a critical flaw in the early series production engines in the P-80A which wasn’t identified until several failures, fatal crashes and severed tail planes, a simple quality control issue in turbine manufacture (rectified iirc during the third series of the first variant and retrofitted). So again it was a reliable and in this case excellent engine but if placed quickly into production under wartime conditions it was breaking ground that would’ve got a lot of pilots killed (a wartime pilot saying is “never fly a prototype or the A-variant of anything”).

    The continued development of piston engine fighters until jet aircraft had fully come of age was a necessary one, the Me-262 (and P-80A, Meteor) were a sign of things to come but premature as the primary front line type in 1944-45. An Me-262 as has already been noted would flame if the pilot so much as sneezed hard, the early P-80A liked to sheer its tail off and send a turbine out its sides like a frizbee, and the MkI Meteor wasn’t any different in performance to a Bristol Beaufighter with much less loadbearing, reliability and armouring. Certainly their development pace was quick but 1945-6 was really the realm of the Griffon Spit, Centaur Tempest/Fury, P-47N, P-51H and Ta-152 had the war continued.

    In terms of comparative jet performance, the Vampire wasn’t going to enter service by say Jan45 and the MkI Meteor hasn’t got a show against contemporaries (MkIII is a different story), so it comes down to the P-80A-1 and the Me-262A-1a, and both have some serious engine issues.
    Messer has management problems related to steel quality, Shooting Star has critical failure ones related to turbine blade manufacturing process.
    The two perform very differently to each other but are quite contemporary at least on paper. Messer has better handling qualities and similar performance at combat altitude (12-18,000ft), the P-80 is faster at low alt and whilst slower at high alt, it was noted for good handling characteristics at high alt (if the nose has ballast or a full ammo load).
    I’d have to look up some material to give more detail but have test pilot reports (NACA and Wright-Patterson) of both types in an e-book.

    An incapability of flight system CPU’s to encompass many of the traditional functions of multi crewed birds, in the combat environment so far appears a not entirely overwhelming argument.

    I might suggest the design requirements given by operators. The dual seat Rafale (after several revisions) for the FAF listed a primary role in strike operations. The single seat Rafale for the FMAF for a primary role in fleet defence and air superiority. The Eurofighter was optimised for air superiority and is single seat. The Su-27 Flanker is single seat for counter-air/interception as primary. The Su-30 two seater has two variant missions as command/control for interceptors (bolstering MiG-31) and multirole strike.
    The F/A-18D in pilot/RIO layout (as opposed to dual control F/A-18B or USN D but I don’t think there were many of these) is for USMC multirole with a strike emphasis (and night operations). Same idea behind F-15C compared to E (pilot/WSO layout unlike dual control D), where the C has presently all the E upgrades anyway so the same approximate capabilities.

    From this one might infer the penetration strike mission or force interdiction is best served with a second crewmember to handle ECM and mission support, whilst a single crew member is adequate for air superiority/counter-air and escort operations in coordinated doctrine likely to feature AWACS/EWR and a variety of escorting warplane types in or available to the combat zone.

    The extra crewmembers are in an AWACS, ships BattleBridge or Gound Control base. You can see this system in action watching Red Flag, where AWACS will continually enhance SA of individual fighter pilots (lookout, you’re on a collision course with MustangTwo, change alt, etc.).

    The exception would be the Russian system (adopted by India with the MKI Flanker datalink), whereby PVO interceptors outside the EWR system can still function as GCI by use of airborne command/controllers escorting and directing the fighter force. These MiG-31 and Su-30 are dual crew for this reason, but other interceptors in the flight will be regular MiG-29/Su-27.

    The answer to the OP would appear to be: depends on the mission requirement. For straight up fighters like the F-16 in a mundane front line role a single crew member is fine.
