    I’m sure that I read somewhere that her Crossley Pielstick 16PC2.6 don’t lend her the best of peformance.

    I was referring to the choice of commercial diesels over Gas Turbines, for the reasons outlined above. If they picked the wrong specific engines for the job, that’s another matter. She seems to get from A to B without much fuss though.

    Any chance of a STOVL version?

    Yes. It’s called a Harrier. Think there’s some ‘runners’ down in Kernow…;):D

    I am really beginning to believe that Russia wants the ship and badly! As its just dumbfounding on how she continues to treat India. Just doesn’t make sense…….:(

    I have a sneaking suspicion that the Russians are putting the price up in the hope that India will back out of the deal… :diablo:,then the Russian Navy will get a second carrier to take the pressure off Kuznetzov and bridge the gap until they can get their recently announced new carrier program off the ground. The only question then would be whether or Not Vikramaditya caould comfortably operate the Russian Navy’s SU-33s (I’m thinking mainly about the lifts and the hangar) as she was redesigned with the smaller Mig-29s in mind. Might be a bit of a squeeze…:eek:

    I’d be surprised if Vikramaditya survives more than 15 years in service, as she seems to me to be a stop gap for the IAC program. Whether she is replaced in service by IAC2 or 3 remains to be seen, and is dependent on how quickly the latter two ships can be completed. If the program goes as smoothely as the IN hopes then Vikramaditya may well still be in service when IAC2 commissions and pay off shortly before IAC3 is completed. I think it’s more likley she will go shortly before IAC2 is completed, though she may well spend a protracted period ‘in reserve’ on extended readiness (though in reality laid up awaiting a short trip to Alang). As I said I don’t think she will spend more than 15 years at sea, though that may be spread out over a few more years by reducing sea time =, although this does have a detrimental effect on the combat readiness of the air group and the ship’s crew themselves.

    🙁

    Even if its a bit delayed i still prefer Indian equipment. And guess what as my country makes economic progress more and more money will be allocated to R&D and manufacturing facilities.

    These are our leaning steps, wait till we are on our feet proper :diablo:

    Its still pathetic for a country like Russia to be 3 years behind schedule with a refit and counting……

    The Russians always saw the Vikramaditya as a training ground for their own engineers and shipyard workers to learn how to build their own next generation of carriers. they are making all the usual mistakes the constitute a learning curve on someone else’s ship at someone else’s expense, so that when they get round to starting work on their own ships they will be better placed to do so. Meanwhile India has been taken to the cleaners.:(

    As far as I can tell, Large commercial diesel engines as fitted to Ocean have similar up front buying costs to Gas Turbines the reals savings come in running and maintenance costs, requiring far fewer engine room personnel to look after them. Hence Super Tankers and other large merchant ships needing only a handful of engineers. Compare Ocean’s complement with an Invincible (upon whose hull Ocean’s design was based) and the difference is significant. Efforts to keep Oceans costs down at the design and build stage are generally agreed to have gone a little too far, and many of these problems have been remedied now, but the choice of engines was a sound one IMHO.

    I’m sure that it could. 🙂
    A modified version operates with the yanks of course.

    I’ve long fancied the idea of mating the Hawk 200 nose/cockpit and weapon system with the T-45 fuselage to produce a lightweight low cost naval combat aircraft…;):diablo::D

    Is there anyone SERIOUSLY suggesting marinising the Typhoon?

    Rafaele would make sense. Especially if JSF turns out to be as big a bag of **** as I think it will be. Rafaele will definitely be able to carry Meteor and ASSM for a start.

    Of course Sarko cancelling the Franco-British design second carrier makes it a harder decision politically and economically.

    Al

    Many keep suggesting we Navalise the Typhon, but NOBODY is SERIOUSLY contemplating doing it. As stated previously, anyone who thinks SeaPhoon is plan B for JCA doesn’t know what they are talking about. Plan E at best. Rafaele might be plan D behind the F-35C and the F/A-18E/F if the choice is on technical issues, but will only move up the ladder if there is political intervention.

    On the broader subject of RN Fighters, the side number system has always interested me, being distinct and separate from the RAF’s various systems of sqn/aircraft designation (which have changed so often over the years they must have trouble working out what they mean themselves! Also there doesn’t appear to be a single system in use in the RAF at present, different sqns and aircraft types using various methods almost to please themselves). I’ve worked out a lot of the details for myself over the years but if anyone has any online sources I’d be glad to hear from them.

    Time to scrap Vikramaditya perhaps

    Alway good to hear the old girl is showing the youngsters how it’s done! Mind you the journo need to check the details a little, she wasn’t built in a drydock, she was launched from a slipway back in 53, by the wife of Winston Churchill no less! I think barring any further major screw ups, Vikramaditya will end up serving the IN simply to save face, though any future purchases from Russia will be subject to far stricter contract conditions. If Viraat has any serious problems in service (unlikely) the IN could always lease Invincible to bridge the gap to the IAC, in fact that might not be a bad idea anyway as it will allow the IN to train up a second carrier crew ready to transfer to either of the new ships.

    The balance between fighters and strike aircraft is dependant on the type of mission the carrier is sent on, and to be sure the RN in the 60s showed flexibility when required. With only two commando carriers in service, strike carriers were occassionally pressed into service as makeshift commando ships eg Centaur transporting troops to quell a mutiny by the Tangayikan rifles in the early 60s, squeezing the troops into the hangar deck on camp beds and gingerly moving the ship’s air group around them. At the time Centaur operated a unique air group, composed of 12 Sea Vixens for both Air defence and strike, four Gannets for AEW and six Wessex for ASW/SAR. Previously she had operared with six Vixens and eight Scimitars, but the cramped conditions aboard (and a high attrition rate for the scimitars) lead to the Scimitars being withdrawn and the Vixen sqn being brought up to full strength.

    If Victorious is retained through the 70s unmodified and the Vixens are withdrawn anyway she could carry a completely strike oriented air group of up to 20 Buccaneers, with the usual complement of Gannets and Sea Kings and sailed in company with Eagle or Ark Royal providing fighter cover with their Phantoms, though this would be unlikley given the normal independent nature of peacetime ship deployments.

    And she only has direct diesel propulsion (no expensive gas turbines or electric motors) and she was largely built to mercantile standards. Furthermore that figure is very misleading as there were huge variations in the costs for the individual Type 23s. HMS Norfolk (first of class) came out at £135.5 million whereas later units drifted between £60 million and £96 million. At least part of the savings came from halving the man hours required by each unit during the production run. By comparison Ocean came out at about £154 million.

    Agreed. But the point I was trying to make was that a 20,000 tonne warship was produced for not a great deal more than a 3,000 to 4,000 tonne warship, because the ship’s steel is one of the least expensive aspects of the design. This is also a factor in all the current generation of RN warships (eg Type 45, Albion class LPDs, Bay clalss LSDs and CVF) are so much larger than the ships they are/will replace. The extra volume solves many problems such as habitability and installation of equipment at very litle extra cost, and in the case of improved accomodation will go some way to helping recruitment and retention of service personnel.

    So when designing a new warship, and ecomomies are required, making the ship smaller is one of the least effective ways of saving money, and in the long run can make the ship near impossible to upgrade and retain in service (eg type 21) thus forcing replacement at an earlier date.

    From the American point of view, the Nimitz class are no longer ‘Super’ carriers but ‘standard’ sized carriers, so that is their baseline intellectually. Also in the CTOL/CATOBAR context, there are minimum requirements in terms of deck size to operate the current generation of aircraft, so these define their view of a ‘light’ carrier. To be fair anyone planning on entering the carrier club should beware of defining what can be afforded simply by physical size, as steel is still relatively cheap and constiturtes a very small percentage of the overall cost of any modern warship. For example increasing the size of a ship on the drawing board by 10% to 20% may well only increase cost by 1%, as most of the cost of the ship is tied up in expensive radar and weapon systems (eg Aegis, PAAMS etc). HMS Ocean was reported to have cost little more than a type 23 Frigate, mainly because she had only basic self defence weapons and sensors.

    At the last Franco-Italian summit in Rome, which was entered into an agreement for the transfer of nuclear technology to Italy, the President Sarkosy has thrown flat on the proposal of a common carrier between the 2 countries.

    The problem is that the requirements are too different, CATOBAR vs STOVL, and if also Italy found the money to fund half units would be more logical to build a second Cavour.

    If the requirements were similar, having an aircraft carrier each, have a common carrier would be interesting and with an appropriate managing of the work on the 3 unit in order to have always 1 operative carrier for nation.

    Once CVF/F-35B are in service, France will be the odd one out in terms of aircraft operated by European nations, as Britain, Spain and Italy will all be Lightning B operators and will be able to cross deck easily, making joint ops more straightforward.

    Why fit the Bucc airframe with Tornado avionics to produce a Mk3 Bucc? Because then you will have a superior strike aircraft to the Tornado of course! And that’s the opinion of the pilots who flew both.:D
