    Well I think your emphasis on build time is rightly put. But I fail to see the connection between build time and design experience once you have a design finalized.

    Because of the lack of carrier design experience, China would no doubt take a lot longer to DESIGN a carrier then nations that have designed and built carriers before. However, once those designs had been finalized and construction started, the building process would be no different then that of any other warship – you just follow the plans and apply the technology and skills you used on bigger and more complex designs on this project.

    These are conventional carriers, so there is not the added complication of trying to build, install and test nuclear reactors. The only things that would effect the build time is the quality and quantity of the necessary men and machines. Thus past construction projects are the most important determining factors, and little else.

    I suppose experience in designing such vessels, experience in building them and experience in operating them can be distinguished. As far as experience with building is concerned, not only is an aircraft carrier quite a different thing to build than a tanker or a bulkcarrier, but there is also a learning curve in building a particular type of vessel again and again. Hence, I would expect a first of class to take longer to build and trial than then next or, say, the tenth)

    Also, without prior experience in building and/or operating, even after having studied various existing designs, one could still finalize a design only to discover during building or operating that some of the design solutions chosen are not optimal from the perspective of building or operating.

    This is all giving me a headache.

    What is the RPK-7 then? 650mm 120KM range sub launched SS-N-16?

    http://en.wikipedia.org/wiki/SS-N-16

    Is there is source that compiles all of this info?

    I don’t see why a Typhoon wouldn’t have 650mm tubes anyway. The thing could have 20 of them.

    FRIEDMAN: Nato missed the distinction between the two generations of the system, both of which existed in 53 and 65cm form, identifying the 53cm weapons as SS-N-15 and the 65cm weapons as SS-N-16.

    Note the use of plurals (“weapons”) rather than singular (“weapon”)
    RPK-7 > SS-N-16 (sub as well as surface launched)

    В декабре 1969 г. в ОКБ Минавиапрома “Новатор” под руководством главного конструктора Л. В. Люльева начались работы по созданию новых противолодочных ракетных комплексов второго поколения “Водопад” (калибр 533 мм) и “Ветер” (650 мм), предназначенных в первую очередь для оснащения перспективных АПЛ третьего поколения.
    В отличие от своего предшественника, ПЛРК “Вьюга-53”, “Водопад” должен был комплектоваться как специальной боевой частью, так и самонаводящейся малогабаритной торпедой УМГТ-1 (разработчик – НПО “Уран”) с дальностью реагирования по акустическому каналу 1,5 км, дальностью хода до 8 км и максимальной скоростью 41 уз. Использование двух типов комплектации значительно расширяло диапазон применения оружия. По сравнению с комплексом “Вьюга-53” у “Водопада” резко возрастала максимальная глубина старта ракеты (до 150 м), увеличивался диапазон дальностей стрельбы (с глубин 20-50 м – 5 – 50 км, со 150 м – 5 – 35 км), существенно уменьшалось время предстартовой подготовки (10 с).
    “Ветер”, имеющий в два раза большие, чем у “Водопада”, максимальные дальность и глубину старта, также мог комплектоваться как торпедой УМГТ, так и ядерной боевой частью.
    Комплекс “Водопад” под индексом РПК-6 поступил на вооружение ВМФ в 1981 г. (им оснащались не только АПЛ, но и надводные корабли), а “Ветер” (РПК-7) – в 1984 г.

In contrast to its predecessor, [PLRK] of ” Blizzard -53″ , ” [Vodopad]” it had to be completed by both the special warhead and by homing small torpedo [UMGT]-1 (developer – [NPO] of ” [Uran]”) with the distance of reaction along the acoustic channel 1,5 km, the distance of motion to 8 km and a maximum speed of 41 knots the use of two types of assembly considerably enlarged the range of the application of a weapon. In comparison with the complex of ” Blizzard -53″ in ” [Vodopada]” the maximum depth of missile takeoff (to 150 m), sharply grew, the range of the ranges of fire (from the depths of 20-50 m it was 5th 50 km, with 150 m it was 5th 35 km), increased, substantially it decreased the time of prelaunch servicing procedure (10 s). ” [Veter]” , that has two times greater than in ” [Vodopada]” , maximum distance and the depth of start, also it could be completed by both the torpedo [UMGT] and by nuclear warhead.

    From the online version of “The Naval Institute Guide to World Naval Weapons Systems, 1997-1998” by Norman Friedman. Naval Institute Press, 1997. ISBN 1557502684, 9781557502681.

    on page 603 (in relation to the use of Ka-27):

    However, the helicopter may also have been seen as a targeting device for RPK-6/7 (SS-N-16 with torpedo).

    on page 667:

    RPK-6/7
    These 53cm (RPK-6) and 65cm (RPK-7) successors to RPK-2 entered service in 1981 and 1984. The Vodopod system (83R missile) uses a torpedo warhead (UMGT-1) and the Vodopei system (84R missile) presumably uses a nuclear depth bomb warhead. An improved version is URPK-6 (Vodopod/Vodopei-MK, using 83RN and 84RN missiles). The associated surface ship systems are Veder (86R missile, torpedo) and Vspletsk (86R missile, presumably with a nuclear depth bomb). Projected range with the Orlan (UMGT-1) torpedo was 100-120km (54-65nm). The current RPK-6 payload is APR-2E, the current RPK-7 payload is the short 53 cm torpedo.
    The RPK-6 surface version arms the missile cruisers Frunze and Kalinin. In these ships, it is fired like a torpedo, dives into the water, stabilizes itself, and then ignites. In effect, it replaces SS-N-14. It may have been chosen to arm the Krivak III and modified Udaloy, although the appropriate torpedo tubes were not fitted. Neustrashimy, which has torpedo catapults like those of French ships, may have the 65cm RPK-7.

    From the online version of “The Naval Institute Guide to World Naval Weapon Systems” by Norman Friedman. Naval Institute Press, 2006. ISBN 1557502625, 9781557502629.

    on page 542:

    The Klub system embraces several differen missiles: Klub-N for surface ships and Klub-S for submarines, within each of which are 3M54E and 3M54E1 antiship cruise missiles, the 3M114 land attack cruise missile, and the 91RE1 antisubmarine missile (see RPK6/7 entry). All use common interfaces to a single fire control system; all may even be launchable from the same tube or tubes – presumably, both standard torpedo tubes and the new vertical launchers for frigates.

    on page 714:

    RPK-6/7 Vodopod/Vodopei/91RE (SS-N-15/16)

    These torpedo tube launched missiles supersede RPK-2 Vyuga. Both carried nuclear depth bomb payloads. RPK-6/7 was a more sophisticated derivative with eiter a homing torpedo or a nuclear depth bomb as payload. Vodopod (83R missile) carries a torpedo, Vodopei (86R missile) a depth bomb. Veder (86R missile) and Vspletsk (86R missile) are the surface ship equivalents, fired, respectively, from a torpedo tube and from a catapult (in the new frigate Neustrashimy). The torpedo was originally UMGT-1 (40cm) for the 53cm version, and a short 53cm torpedo for the 65cm version. Projeected range with the Orlan (UMGT-1) torpedo was 100-120km (54-65nm). The current RPK-6 payload is APR-2E; the current RPK-7 payload is the short 53 cm torpedo. The surface version of RPK-6 currently arms the large cruisers Frunze, Kalinin and Pjotr Velikiy. In these ships it is fired like a torpedo, dives into the water, stabilizes itself and then ignites. In effect, it replaces SS-N-14.”

    on page 715:

    Neustrashimiy, which has torpedo catapults like those of French ships, may have the 65cm RPK-7. RPK-6 range is 37km; RPK-7 range is 100km and can be fired at twice the depth of RPK-6. RPK-6 weighs 2,445kg and is 8.2m long( 53cm tube size). RPK-7 is 11m long (65cm tube size). Nato missed the distinction between the two generations of the system, both of which existed in 53 and 65cm form, identifying the 53cm weapons as SS-N-15 and the 65cm weapons as SS-N-16. It is not clear whether any RPK-2s remain in service.
    The torpedo-armed version of this missile is offered for export as 91RE, as part of the Klub system in tandem with the 3M54E antiship cruise missile (see S-10 Granat entry). The submarine-launched version is 91RE1, the surface ship version 91RE2. The former is designed for launch from a 533mm (21 in) torpedo tube at a depth of up to 150m (submarine speed up to 15kt);total weight is 2,050kg. Effective range is 35km, The surface-launched91RE is described as weighing 1,200kg (which seems unlikely), with a range of 40km.
    Veter and Vodopod were tested onboard two converted Romeo-class submarines (PRoject 633RV), S-49 (1973) and S-11 (1982).For these tests, the torpedo payload was a UMGT-1 lightweight torpedo, fired at a bravo-class target. Vodopod was adopted for service in 1981 as RPK-6, with both nuclear and torpedo payloads. Veter was adopted in 1984 as RPK-7, also with both payloads.

    Notes:
    UMGT-1 (a.k.a. APSET-95 for export a.k.a. NATO 40-79) = an air-launched 400 mm antisubmarine torpedo used in RPK-6
    APR-2E = an air-launched lightweight active/passive 350 mm anti-submarine rocket torpedo, which replaced UMGT-1 in the improved URPK-6
    http://www.aeronautics.ru/archive/reference/Air_Launched_Torpedoes/Russia.htm and Friedman (2006: 737)

    This suggests a weapon system
    a) in 2 diameters (for 2 different type of launching tubes)
    b) each with 2 possible warheads (torpedo or nuclear depth charge)
    b) each in two launch versions (submarine and surfaceship).

    A very nice vessel but with a dated machinery set. It was orginally planned that the class would get the WR21 but it was not available at the time. There is some suggestion that the machinery space design could still accomodate such a plant.

    At first it appeared that the main engines for the ships would be the new Rolls Royce WR-21, which will also be deployed on the Royal Navy`s Type 45 Destroyers. Unfortunately the WR-21 was not available in time (apparently it won`t be available until 2007), so for now the main engines will be Rolls-Royce SM-1C ‘Spey’ gas turbines, which are a good design which unfortunately is getting on in years. However, when the ships were designed the engine room was designed with the WR-21 in mind, and there is room for these turbines. It is not unlikely that the ships will recieve the WR-21 later on in their operational lives, a move which would substantially increase fuel efficiency and raise engine power.
    Secondary engines have always been two Wartsila diesel engines, and the engines drive two adjustable counterrotating propellors

    http://www.kitsune.addr.com/LCF/information.htm

    Logistics commonality may also have played a role, both withing RNthN and in NATO. The RR SPey Gtu / Wartsila diesel combination was already being used on the Karel Doorman class M-frigates (this had Stork-Werkspoor diesels, but by the time of the LCF Stork-Werkspoor had been taken over by Wartsila). Earlier dutch ship classes (Tromp, Heemskerck, Kortenaer) had RR Tyne and Olympus Gtus. UK Type 23, Canadian Halifax, Greek Hydra and Norwegian Nansen classes also employed or would employ the Spey.

    Can i ask what the F/A-18E has over the MiG-35?, seeing as the indians are already buying a whole lot of MiG-29K’s for their navy, and they already have the infrastructure set up from flying MiG-21’s and 27’s. Additionally, I can see the US being heavy on the sanctions if India ever steps out of line.

    That, plus:

    The MiG-29 forms three operational squadrons (No.28, No.47 and No.223) in the IAF. A fourth squadron was expected to be raised, however plans for that have been scrapped. IAF MiG-29s have had their share of technical problems, since its induction in 1986. In 1994, a joint aviation venture, the Indo-Russian Aviation Private Ltd., in maintenance & support was set up by HAL and MiG-MAPO and the technical problems were rectified to a satisfactory level. SIPRI (Stockholm International Peace Research Institute) reports that eight MiG-29S Fulcrum-Cs were ordered in 1994 and were delivered by 1996. Also from a SIPRI report is a 1995 order of two MiG-29UB Fulcrum-Bs, which were delivered by 1996.

    Weren’t there subs along with those carrier fleets that couldn’t detect that inferior Chinese sub. Shouldn’t they have been the first to detect those subs? And if I recall correctly, one wasn’t detected until it surfaced, popped its hatch and waved to the big bad mighty carrier sailing by. :diablo:

    Likewise, in wartime, when it will be hiding, the sub would have to locate the carrier group in the first place, which will not be a piece of cake, compared to peacetime. Let’s not attempt to change this into a discussion about subs and/or superiority/inferiority of China’s technical capabilities. We are discussing how likely it is that 2 new carriers will enter service in 6 years. Don’t try to derail this thread!

    Then what’s everyone worried about? By so many reactions in here, what’s all the peeing in the pants over two carriers? Notice no one actually answers this question because you’re right. This is about a status symbol and nothing more… on the side of the people peeing in their pants. They just don’t want China into the club. A lot of schizoid reactions. That pretty much tells it all.

    Who says anybody here is worried. Interest here is with whether public statements about Chinese carrier plans are accurate in the sense of being feasible. Think again before you call anyone here schizoid.
