    According to the manufacturer.

    16 hours total endurance with a 500lb payload (i.e. ISR only).
    10.5 hours at 1500 km from base, with same payload.

    Why do you say ISR only? The Selex ES Falco Evo (i.e. the larger version of the Falco), which I believe has been doing only ISR for customers, has a max payload weight of 100 kg.

    The MQ-9 Reaper has an internal payload of 360 kg, besides hardpoints. 226 kg (500 pounds) – 100 kg = an extra 126 kg for payload compared to the Falco Evo. However that is assuming that the payload design is not modular, where you swap out unwanted kit. The Falco design is modular (with 4 different modules for customers to choose from), and (from the page you linked) the Hammerhead’s “capabilities include being able to host several payload combinations” … “as well as other roles”. The UK CAMM missile, for example, is 99 kg I believe. Gen. Claudio Debertolis also said the Hammerhead could be armed

    I agree with mrmalaya: combined fleets of unmanned hammerheads with manned aircraft (Piaggio MPA or other) could be a very interesting prospect.

    The claimed performance is also very attractive, in terms of endurance, (mammoth!) payload, cruise ceiling and top speed. In other words Piaggio are claiming that the Hammerhead can fly faster than its competitors at Mach 0.7 to target area and then also loiter longer in the designated area for 16 hours of endurance. I believe that the Reaper’s top speed is around half that much and the endurance is 14 hours at full load. It would be interesting to know if the claimed 16 hours for the Hammerhead is at full load.

    Engineers from Thales Alenia Space Italy flown in to rescue Galileo project from Germany’s OHB.
    (in French)
    « Les décideurs européens ont promu un outsider qui sort aujourd’hui des produits en retard, au double du prix prévu, et qui a besoin de l’aide des deux grands pour s’en sortir »
    “Europe’s decision-makers have promoted an outsider which today delivers products late, at double the expected price, and which needs the help of Thales Alenia Space and Astrium to sort things out”

    Finalement, OHB a demandé fin juin à Thales Alenia Space de l’aider pour l’intégration et les tests. Dix à quinze experts en ingénierie de la filiale italienne de TAS sont partis en Allemagne en septembre, et resteront jusqu’aux premières livraisons.
    Finally, at the end of June OHB asked Thales Alenia Space for help for integration and testing. Ten to fifteen engineering experts from TAS Italy went to Germany in September, and will remain there until the first deliveries.

    Galileo is Europe’s GNSS system for both military and civilian applications. The satellites feature a Selex Passive Hydrogen Maser atomic clock and were originally based on the French Proteus platform.

    Why would they publicly make such statements?

    I thought they already had:

    http://www.flightglobal.com/news/articles/reduced-f-35-performance-specifications-may-have-significant-operational-impact-381683/
    “This is going to have a big tactical impact,” one highly experienced officer says. “Anytime you have to lower performance standards, the capability of what the airframe can do goes down as well.”

    “What an embarrassment, and there will be obvious tactical implications. Having a maximum sustained turn performance of less than 5g is the equivalent of an [McDonnell Douglas] F-4 or an [Northrop] F-5,” another highly experienced fighter pilot says. “[It’s] certainly not anywhere near the performance of most fourth and fifth-generation aircraft.”
    At higher altitudes, the reduced performance will directly impact survivability against advanced Russian-designed “double-digit” surface-to-air missile (SAM) systems such as the Almaz-Antey S-300PMU2 (also called the SA-20 Gargoyle by the North Atlantic Treaty Organization), the pilot says. At lower altitudes, where fighters might operate in for the close air support or forward air control role, the reduced airframe performance will place pilots at increased risk against shorter-range SAMs and anti-aircraft artillery.
    Most egregious is the F-35C-model’s drastically reduced transonic acceleration capabilities. “That [43 seconds] is a massive amount of time, and assuming you are in afterburner for acceleration, it’s going to cost you even more gas,” the pilot says. “This will directly impact tactical execution, and not in a good way.”
    Pilots typically make the decision to trade a very high rate of fuel consumption for supersonic airspeeds for one of two reasons. “They are either getting ready to kill something or they are trying to defend against something [that’s trying to kill] them,” the pilot says. “Every second counts in both of those scenarios. The longer it takes, the more compressed the battle space gets. That is not a good thing.”

    Then again do you even need such statements? The downgrading of the spec (i.e. drastic non-compliances) and huge cost increases (including the “no-engine” figures!) means that the “partner” countries embroiled in this concurrent development and production have either reduced their potential orders or walked away. It’s not just Canada that’s in this mess.

    In this case M346 > Yak-130.

    I second that, but with extra emphasis: M346 >> Yak-130

    Yes, I saw the use of the conditional, and hence refrained from saying “have purchased”. Would “shall purchase if certain conditions are met” satisfy your concerns?
    I believe enthusiasm only (perhaps applicable to ProjectZero) would be far more off the mark. They go as far as mentioning how many the initial order would consist of. It’s only natural that some details have yet to be ironed out, as the articles also mention that the first flight is to take place some time this year. The enthusiasm is there, irrespective. The contract is conditional (this doesn’t mean that there is a preliminary contract, but that a contract will ensue if the requirements are met). They don’t even say that the Hammerhead would be one of our candidates, but rather that [I]it would be our candidate[/I]. If this had been pure fancy you wouldn’t have so many articles being written about it in the specialized press, nor would Gen. Claudio Debertolis be making statements on the issue. At no point has it been said that a contract has already gone through

    I’ve been looking into getting a scooter recently, it’s the only reason I was familiar with the Piaggio name at all! I did some reading on Wikipedia just now — interesting company history.

    The MP3 design is certainly innovative and by all accounts has a lot of practical advantages, but the aesthetic doesn’t really do it for me. Nor does the maxi scooter aesthetic. I have my fingers crossed that Piaggio brings their new 330cc engine to the Vespa and Aprilia lines soon — big upgrade over the current 278cc! Peugot scoots aren’t available here anymore (2009 models were the last imported) so I haven’t been following them.

    Same here. I wouldn’t mind trying one of these larger scooters for the heck of it, but I wouldn’t buy anything larger than a Vespa.
    Incidentally this may seem off-topic but it isn’t entirely. Improvements in automotive combustion engines can have a direct bearing on aerospace applications. e.g. the Sky-Y UAS I linked above uses a Fiat common rail engine.

    …or we go with the KingAir 350ER marpat that is already developed, that the RAF and RN both use in other roles, have an established support/logistics train for and actually train multiengine pilots on currently!. Dont think the Piaggio is going to beat that for economy to be honest!

    Until the comprehensive costs of the Piaggio MPA and Hammerhead are known, it’s hard to say. That said, the basic model (not the ER), again according to the wiki page is in the range US$M 5.24–7.57, so it would seem very much in line with the Avanti. I am assuming that the ER version costs more than that. If you don’t have to have pilots on each aircraft (ER vs Hammerhead) then presumably this would entail considerable savings at fleet level.

    What’s more this does seem to be a case of apples and oranges:
    http://www.hawkerbeechcraft.de/King-Air-350ER.205+B6Jkw9MQ__.0.html
    These enhancements provide the King Air 350ER with more than eight hours of endurance and the flexibility to loiter low and slow or cruise at 300 knots and 35,000 feet.

    I haven’t been able to find loiter speed figures for the ER.

    The 16 hours figure is the only prob for it as maLE drone. Btw it has MPA wings.

    Are you certain? To the best of my knowledge, in the one-ton class the Alenia Aermacchi Sky-Y detains the european endurance record with an 8-hour flight (test campaign at Vidsel range in Sweden, September 26 – October 25 2007)

    With all the suggestions of exotic airframes for the MPA, can I just remind everyone that there simply isn’t the money for a gold plated aircraft of which the UK will probably be the only user.

    We need an off the shelf solution.

    http://www.defense-aerospace.com/article-view/release/145946/piaggio-unveils-hammerhead-uav-at-paris-show.html
    http://www.defensenews.com/article/20130618/SHOWSCOUT02/306180021/Italian-Procurement-Chief-Backs-Hammerhead-Replace-Reapers

    The Italian armed forces are purchasing 10 Hammerhead aircraft if it meets their requirements. The article doesn’t mention the cost of the aircraft, but the Avanti civilian aircraft, on which it is based, from the wiki page costs US$7M. In other words not only does the Hammerhead promise to be technically unbeatable on many fronts (and for the UK with extra industrial benefits through Selex ES UK), but it may prove to be by far the most economical solution, allowing for formation flying – as is done with LEO satellites, interferometry, etc.

    Huh, and I thought Piaggio made scooters.

    They do, but that’s a different Piaggio. Both were founded by Rinaldo Piaggio in 1884 but today these companies are unrelated: Piaggio & C. for scooters, Aprilias, etc. and Piaggio Aero Industries for aircraft. Indeed more often than not, it’s not even Piaggio: a company in India still license-produces the original Vespa for the Indian market. While I like the looks of the new Vespa, I’d also be curious to try the MP3 (two wheels up front): somehow the Parisians have gone goo-goo over these (to the point that Peugeot now have their own version)

    Besides the ATR-72-600 MPA and Piaggios, another MPA to consider is the C27J. I say this because such a version has apparently been marketed, and because performance-wise it easily outdoes the Airbus equivalent.

    Piaggo is a very fine airplane, but i’m dubious about the excellent loitering capabilities… talking a lot with one of its engineers (P. Nurra) abbout that.

    I admit I didn’t have any loitering figures for the Hammerhead. I saw it at the Piaggio stand at LeBourget and wanted to ask, but the Piaggio personnel were staying inside their pavilion as there was a bit of drizzle 🙂
    However I have found some figures on the web:
    http://www.flightglobal.com/news/articles/farnborough-piaggio-to-develop-maritime-patrol-avanti-374185/
    The MPA is powered by Pratt & Whitney Canada engines, with a loitering speed both at low and high altitude, coupled with a 350ktas cruise speed for maximum mission flexibility. Its operating ceiling of up to 41,000ft allows for high altitude operations with an endurance of more than 10 hours.
    http://p1hh.piaggioaero.com/
    The design of the P.1HH HammerHead aims at being a unique ISR platform, able to climb up to 45.000 feet, loitering quietly at low speed (135 KTAS) for an endurance of up to 16 flight hours and dashing at very high speed (up to 395 KTAS) to target.

    The Hammerhead incorporates the skyISTAR multi-mission integrated sensor system from Selex ES, featuring the SeaSpray 7300E Radar (state-of-the-art Active Electronically Scanned Array (AESA) with a Commercial Off-The-Shelf (COTS) processor). The MPA incorporates a surveillance system from SAAB. With a UK order for the type, Selex ES in the UK would perhaps be developing more of the mission packages.

    I would go for a mix of ATR72-600 MPA, Piaggio MPA and Piaggio Hammerhead.

    Alenia Aermacchi delivered the first ATR72-600 TMUA (Turkish Maritime Utility Aircraft) to the Turkish Navy last Wednesday.

    http://www.defense-aerospace.com/base/util/146755_1F.jpg

    The derivatives of the Piaggio Avanti afford excellent loitering capability despite having exceptional speed for a turboprop, together with unmatched cabin x-section and volume for its class as well as endurance (due to the innovative and very aerodynamic design). With the Hammerhead one would also have a first experience with unmanned aircraft of this class.
