    Similar ideas had Argentinia about the Falklands and was awful wrong. It is not about Taiwan at first, but the credibility of the USA. China will be well advised to seek a solution similar to Hongkong, which does allow all parties to keep face.

    Apparently Rand company does not think US can hold air superiority in the vicinity of Taiwan.

    Has anyone told the RN? :diablo:

    I suggest you look up the planned powerplant of the CVF carriers. BTW, it’s scalable for bigger ships, or for higher speed in the same ships. Cruise ships – some of them larger than any carrier – use diesel, gas turbines, or a combination.

    What RN doing is something out of the ordinary. They chose a less reliable design with less fuel flexibility.

    Have you told Man B&W? Or Wartsila? I think they’d be surprised to hear that their diesels, powering container ships of 100K tons at 25 knots, were not designed for the job.

    They run at 25 knots at the expense of increased fuel consumption.
    FYI a increase from 20kts to 25 kts increases fuel consumption by 50%
    Now wait until you reach 30kts+…

    Or cruise ships . . . . what about Carnival Spirit – 88500 tons, cruise speed 22 knots (max 24), diesel-powered?
    Among smaller cruise ships, speeds of up to 27 knots are achieved with diesel propulsion, e.g. Olympic Voyager (24400 tons). Combine the hull shape of the latter & the propulsion of the former in a ship of about 60000 tons, & what would you get?

    A heavy engine taking up too much space.

    The production of fresh water via reverse osmosis does not use boilers. Again, look at CVF – or Albion, Bulwark, or cruise ships.

    That’s only a convenience when going diesel/gas electric. which increase engine room size with generator and converters.
    On a carrier space maximization is very important.

    But Heathrow and Beijing airport is so very relevant to carrier building experience? :rolleyes: How do you know the carriers are going to be steam powered?

    Simply because there is no suitable diesel or Gas turbine solution for powering carriers. Commercial marine diesel currently available are designed to run at only 16kts and are too massive in size.
    Btw a carriers will always need boilers for fresh water. It makes sense to reduce redundancy.

    Excellent article…………………and explains how complex ship construction can be. ๐Ÿ˜Ž

    I hope you realize that nothing in that article relates to carrier building experience. Diesel or Gas turbine propulsion design does not equate to carrier propulsion. The lack of mature Chinese design of gas turbines or diesels means nothing in this case. BTW Chinese steam turbine tech is quite mature hence the emphasis in the 051B/C designs.

    No I would not take the European yards experience as any benchmark either. There is only one place and one yard that has been continiously building Carriers (the most advanced, large and complex by the way) and that is Newport News. No one else can say that they have had a carrier on the slip for every day since World War II. They can.

    They are able to build a Nimitz Class in about 6-7 years. That has been earned by building the same design for about 30 years now and also by continious process effeciencies that come with experience.

    I cast no aspersions against anyone here, including, China, Italy, Spain, France the UK and Russia. But none of these nations have had the same kind of continious experience as the Americans and their less complex and smaller ships have taken at least as long or longer than any Nimitz class takes to be built.

    The first time out a decade is about right to build one of these things considering all of the lessons that can only be learned by doing.

    Heathrow aairport took nearly 20 years, Beijing built one with twice the size for half the price and took only 4 years.
    There is no straight forward benchmark especially for high esteem projects in China.

    Well, two are official……………….Yet, many more are likely on the way.

    The single-seat, twin-engine Su-33 (also known as SU-27K) is the naval variant of the Su-27 Flanker fighter aircraft. Developed in the early 1980s for operating from the Soviet navyโ€™s aircraft carriers, the Su-33 uses folding wings and uses an additional pair of canards to improve control at very low speed (useful for maneuverability, as well as for takeoff and on landing approach). China currently operates two variants of the Su-27 fighter family in its air force and navy: the Su-27SK/UBK fighter and the Su-30MKK fighter-bomber. The Su-33 would become the third variant of the family to be serving with the Chinese armed force.

    Russia and China are finalizing negotiations for the delivery of up to 50 Su-33 carrier based jet fighters, at a cost of US$2.5 billion. China is expected to get two Su-33 jets to be used for evaluation and operational trials on the on the ex-Soviet carrier Varyag China acquired from the Ukraine in 1999. The carrier is currently stationed at Chinaโ€™s Dalian Shipyard, being refitting since 2002. Once commissioned to service, the carrier will be able to operate the 12 aircraft of SU-33, which are included as the first option part of the current program. Eventually China could buy up to 50 aircraft of this type, to equip the first indigenous Chinese built aircraft carrier expected by 2010.(see original coverage at Sinodefence.com)

    If you can read chinese then this would be interesting to you.

    Let me help you out just in case…
    The caption reads Company ceremony for the delivery of landing gears for certain aircraft.
    The red banner reads J-xx landing gears delivery ceremony
    Now note the PLANAF uniforms.

    you can connect the dots…

    So JANES is in need of update. ๐Ÿ˜‰

    MSOV is unpowered…:rolleyes:

    WJ1-TE-004 is more like Storm Shadow but with sub munitions instead of a single HE charge.

    So this “thing” is called WJ1-TE-004 …. :confused: Any other related information if it is a stand-off or cruise missile or just submunition dispenser ?

    Thanks, Deino

    Surprisingly it’s both…

    It’s a stand off submunition dispenser used to attack airfields.

    Any idea what the specs are for the specific model of engine it uses?

    No… only the manufacturer published specs for the FN1.

    Short taxi near vertical takeoff right from the get go. The thing has a lot of thrust.

    With warships where the search radar is mounted at the rear, how does the radar see through the mast to scan forwards?

    Turn to port. The mast only covers a little arc.

    Russia has just recently threaten Poland with Nuclear Weapons and invaded a small country of only 4 Million. Further, it actions have become more provocative by the day. So, I doubt many would consider my views that outrageous………….:p Really, the problem has more to do with your bias towards the US. As you will suppport any position regardless of its merits……….

    How is this any different from Kosovo?
    Georgia got their @ss handed to them just like the serbs.
    Saakashvili is a right wing dictator basing his legitimacy of govern on inflaming nationalism. He banked on the slow reaction of both russian and US leadership to his ethnic cleaning once he completed his victory in South Ossetia didn’t pay off.
    Russia’s message to NATO is pretty clear and it remains to be seen if NATO is willing to respond adversely to Russia given the precedent of NATO response in Kosovo.

    One supplier of combat aircraft people are forgetting is Taiwan. Taiwan has surplus F-5s that could be upgraded and F-CK-1 fighters. These fighters are not super modern but they would be effective point defense fighters armed with Python-5, Derby, or AMRAAM missiles. Russia could not really do anything to Taiwan since it is not recognized as an independent country and Russia already sells billions of dollars of military equipment to China so it would be some sweet revenge for Taiwan!

    Taiwanese F-5s have pretty much reached their service life. It would be very hard to squeeze any more life out of the air frame. ROCAF have been doing that for years. ROC president MA YinJou have openly said that he would not further threaten relations between the straits with overt diplomatic manouvre. Arms sales to a country with formal diplomatic relations with PRC is out of the question in this case. Plus unless Georgia decides to ditch Beijing for Taipei this is not legally possible.
