    A realistic unitary cost for a medium lift helo (be it NH90 or Blackhawk) currently stands around 20-some million USD each, considering training and such.

    228 millions for Puma upgrade would allow a buy of roughly 10 NH90 or Blackhawks. Not much…

    I fear NH90’s are far more expensive than that, even as bare fly away cost, at least judging from the several purchases released to the public until now.

    If you need to keep upfront costs down, maybe you really are limited to choose between UH-60 and maybe AW149.

    That newspaper seems to me to be popular because of its devotion to keep masses more aware of problems related to mammary hypertrophy than to political issues ones…

    The main problem for any Air Force attacking a naval formation is actually how to find it.

    Even a large naval group cruising, let’s say, 200 nm from the shore will be over the horizon for any land based surveillance network and still capable to menace both a country’s shipping lanes and to strike targets on land, at least targets located very close to the sea, even using only short range cruise missiles like Brahmos.

    It would take only an handful of hours to close in with the shore and launch the missiles, meaning the other side need to lock several air and naval assets just to prevent it, let alone to retaliate against the enemy’s naval group.

    On the other hand, AAW warfare is an higly specialized task, it is not a matter of how many frigates armed with medium range AAW missiles are deployable, nor it is a mere matter of missile’s range.

    It’ mostly about sensors, FCS and CMS, enabling at least one single ship to trace a comprehensive tactical environment, tracking all of the own ships and air assetts, neutral air assetts, enemy assets.

    It should be able to identify and prioritize both enemy air assets and enemy missiles, and to identify or guess potential targets within own naval group, and deploy a defensive sequence.

    The first and foremost requirement for an AAW ship is the ability (better to say its CMS’s ability) to identify as hostile and engage menaces not aiming at herself, and a general purpose or ASW frigate’s CMS is usually lacking this feature, forcing the ship to act just as bastion placed between a potential target and the incoming missile to engage it.

    It’s understood that Pakistan was adding KJ-200 on top of two already purchased and delivered Saab 2000 Erieye, the following order for KJ 200 being until now, seems to me being just rumors.

    It would make sense, for PAF, to give a follow on order for the Saab, being proven and reasonally priced.

    It would make sense too, for Pakistan Government, to ask Saab and Swedish Government to keep undisclosed the customer’s identity, at least for a while, to avoid new and worst domestic rows and turmoil after the collapse of the whole relief organizaton in the aftermath of the floodings.

    I’ll think they are far more concerned above what their people, ulamas and tribes could think about this military expense and its timing, than about what international donors could think about it.

    As for South Korea, they should have ordered since a couple of years Wedgetails, so I don’t think they can possibly look for Erieye, unless the Wedgetail is still so plagued to be really far from being operationally exploitable…

    New built since when and by whom?

    By almost everyone since almost a decade.

    Spain has designed and built Juan Carlos I.

    Australia will buy two slighty modified BPE (i.e. Juan Carlos I).

    France as built two Mistrals, is building a third Mistral, maybe will build a fourth one too.

    Japan has built in the near past three LSD LCAC-capable, Osumi class.

    South Korea has built Dokdo.

    Italy is planning between two and three LHD, rumors got their dock should be LCAC capable (meaning U.S. LCAC 1, of course).

    Every of the above mentioned classes has a dock compatible with U.S. built LCAC 1.

    The last amphibious class designed in western countries lacking a dock LCAC capable seems to be the Rotterdam-Galicia-Bay family, designed in the early nineties.

    I see. IIRC anyway the sticking point for the UAE was that they ordered trainers AND light attack aircraft and the M-346 light attack components were not as goods as the A-50s. Singapore on the other hand is ordering JUST trainer aircraft so the peripheral components of a light attack craft are not import for the training role.

    No, the deal was broken because Finmeccanica offered with M346 production and tech transfer of the Molynx MALE UAV, then under pressures form USA and Israel Finmeccanica was forced to call back the latter and tried to offer to the Emirates the FALCO, a lightweight tactical UAV, and the Emirates were right to make the agreement void.

    It has nothing to do neither with the trainer nor the attack version of M346, by far more credible as attack plane of T/A-50.

    Obviously everyone buys something abroad, but the real problem with russian military industries is the lack of internationalization.

    For the very reason you cannot afford to develop everything by yourself, excerbated in Russia by the ties between Armed Forces top ranks, military industies, security agencies and political elites, russian industries need both collaboration and competition from abroad.

    Is it really BMP-3 the best IFV they can develop?

    Or, is it really usual that a diesel SSK trials last almost five years?

    Or that naval yards aren’t even able to design and build cheaply a good amount of small or medium repleniment ships, and other support ships badly needed by the Navy?

    Or is it possibile that the most modern naval CMS, developed for Steregushy Class, is stll based on a copper ethernet network?

    Actually, the only branch quite successfull is the aeronautic one and mostly because of Sukhoi, it is questionable what Mig, Tupolev and to an extent even Yakovlev and Iljushin are worth of nowadays.

    The other main problem is mental habit of both military planners and engineers: they are still planning and developing weapon systems and equipments based on concepts and models related to total warfare scenarios, of little use in the real world of today.

    Russia won’t be fighting any total war against NATO or China, neither today nor next decades, as long as Russia will have a strong nuclear deterrent and a pretty strong Air Force, but the need to deploy far from Russia land and sea forces will rise again, and small conflicts and proxy wars will be more than likely.

    Russia is facing, and will face more and more the problems related with domestic consensus, calling for limited casualties, short operational tempos and it won’t be possible with amred forces structured and equipped for a global conflict to conduct under the dictates of operative research

    The real drawback I could think of about X3, is that using the two side orotrs to control rotation, it is actually more a STOVL then an helicopter, hindering any chance to operate proficently from ships, through-deck apart.

    I think the Sikorsky is really an awesome concept, you still are able to operate like a real helicopter, you got a smaller main rotor diameter because of the counter rotating main rotors, translanting in slower blade tips linear velocity, and still you can fly really fast.

    Maybe the lack of a coaxial rotor helicopter forced Eurocopter to go that way, speeding up tests and opening the way to prospective new variants of existing models, but I’m not convinced it’s a winner.

    I think Kamov should have a well pondered look at the concept, it could be an awesome option for almost all Kamov’s designs.

    Well, if you are serious believing a large land operation is or wil be soon in the pipeline, you should agree BA could not be shrinked any more, light assets suitable for COIN operations are a top priority, and non SDSR should state that UK won’t be bogged down again in large COIN operation within ten years frame.

    Instead, I’m quite confident nobody at government level believe piracy being any more of a nuance, and the costs of piracy, patrolling, damage and so on are so little that until you find Bin Laden himself living in Somalia, nobody will care at the piracy.

    Even one single year land campaign in Somalia will cost like maybe tenfold of one year piracy’s costs.

    Nor you will solve the problem shooting at blank point against any boat resembling a pirate’s one.

    Somalis use to shoot at themself on a daily base since decades, they would not be really impressed with that.

    I hope you are not serious about it.

    I dare to say nobody, and I mean exactly nobody, is willing, thinking or contemplating any large scale land operation in Somalia.

    You see, whoever will be so bold to land in Somalia, will run away losing me, money and dignity.

    It’s a nightmare, and naval escorts are likely to be the only viable and practical approach to the problem.

    Think about it: U.S., Pakistan, Italy and some others went to Somalia in 1992, reaching zero-point-zero of their goals.

    Ethiopia went to Somalia in 2006, and reached again zero-point-zero goals after three years of fighting and casualties.

    Piracy itself is more estabilished in Puntland, one of the last, maybe the very last stronghold against somali Islamic courts.

    So, who would like to risk huge losses and being again bogged down in a counterinsurgence warfare, at the same very time endangering or alienating the foremost and only “near friendly” part of the country?

    Obviously, no western Government will tell it clear and loud, but the only practical policy is to control piracy at sea as long as economically and politically viable the piracy, being eradication not an option.

    All new built amphibious ships are provided with a dock wide enough for an LCAC, so this could be applied as a de facto standard.

    About San Giorgio class LPDs, they are quite unconventional ships, because they were the response to a urgent requirement raised with the italian deployment in Lebanon in 1982.

    They have been based on a civilian ferry project and the first and foremost requirement was to be as cheaper to buy and to operate as possible.

    Quite obviously that requirement translated in a hull as little as possibile, and again in a dock designed around only italian landing crafts MTM (actually former U.S. LCM dating back to Korean war) and MEN, both less than 19 meters long and 5 meters wide.

    In the end, San Giorgio apart, until your landing craft’s width is no greater than half of LCAC’s width, and they are as long as LCAC (more or less) there is no interoperability or efficency issue.

    But if you are going to deploy landing crafts larger than half LCAC’ width, it is likely you will be forced to put one single landing craft where anybody other would put two slight smaller ones when operating from allied ships.

    In fact there already a few hand held UAVservicing with british police, german Fire Brigades and so on.

    E.g.:

    Draganflyer x6

    Even the Schiebel S-100 is marketed for civilian applicatons too.

    The critical issue, at least here in Europe, is the lack of regulation.

    You simply are not allowed to fly anything unmanned flying higher than an RC model can by laws, period.

    Only military operators, confined in military air spaces, can do it, and it’s quite pointless for any civilian agency, being inherently interested in flying them in the civilian air space.

    The second critical issue, at least for a proper nation wide deployment of UAVs, is the lack of funding for a dedicated wideband telecommunication satellite, or at least, if you are envisaging to use them just in non sensitive applications (i.e. no law enforcement ones) to lease enough badwidth from a commercially managed telecommunication satellite.

    In Europe some countries are studying/developing protocols and fixed ground stations cellular networks alike, to get rid f this problem, and the European Commission is studying a proposal for new air traffic regulations inside European Union allowing a comprehensive and less restricted use of civilian UAVs.

    Back to Russia, it seems to me that one critical issue is missing.

    Until few months ago, Russia had no longer a satellite navigation system, GLONASS has been fully restored only this very last months.

    And Russian MoD still is lacking enough military telecommunicatoin satellites, again only this very last weeks they launched a couple of milcom satellite, and it’s likely they are still based on old projects lacking wideband channels for imagery.

    So there has been no point, better to say no practical sense, on developing strategic levels UAV like a Global Hawk.

    And going down to the smaller assets, they are lacking both practical payloads and the related facilities at the tactical unit level.

    It’s not a matter of airframes or engines, and is only partially a matter of automation or data relaying.

    Russia as a country is not ready to deploy UAVs at the tactical levels, not by itself at least, and is only now restoring those assets mandatory to deploy strategic levels UAVs.

    @H_K

    No, I’m not confusing ships and calissifications.

    I base my own on U.S. Navy standards, it could be questionable if they are the best or most appropriate, but there is intrinsic logical coherence with them.

    By U.S. Navy standards, an LSD is a ship with most of its hull devoted to a very large dock, able to transport and deploy ashore large amounts of landing crafts.

    By the same standards, what you save of your LSD’s hull from the dock is part deck space for motorized or mechanized assets, or berthing facilities.

    There is almost no room at all for storing facilities, either dry or liquid.

    And at the present time, U.S. Navy LSDs are the Widbey Island class ones, whose cutaway is really close to Foudre class cutaway, and related facilities as well.

    By the aforementioned standards, is LPD’s standard (Austin class and now San Antonio class) to provide facilities for logistic support, i.e. mainly stores.

    This is the rationale dictating a dock’s depth of less than 30 meters for San Antonio class vs. around 100 meters for Widbey Island class

    Of course you can sort out of an LSD something resembling an LPD, e.g. you can turn out with sometinhg like an Harpers Ferry, an iteration of Widbey Island with only 30 meters depth dock and plenty of stores builded on the saved room.

    But it is something I would think of for a new built ship, like if Marine National discovered their amphibious fleet is severely impaired by the lack of a logistic amphibious ship (and they actually lack that asset) and like to keep R&D costs low modifying the Foudre project the same way U.S. did with Widbey Island, but ways too expensive to refit in an already built ship.
