    Mark Bailey posted this alternative to the Australian phibs on the warships1 board, I also found it in an argument on another board.

    WW Tamesis class 4th Generation RoRo.

    Working exclusively from open source material shows that a twin-screw ‘militarised’ version of this ship with a starboard side island and a flight deck with a ski-jump, 20m x 30m steel flat products lift (takes 800 tons or a fully spread Chinook), 6 fixed decks with the one below the upper deck given 30′ clearance so to act as a hangar and a slewing dipping stern ramp (300 ton ramp load) would have internal volume for 2500 troops, 40 days of sustainment, 32 helicopters (in the hangar deck) with all their maintenance needs, firefighting gear, 50 Abrams and their support vehicles, 100 M113, 100 ASLAV, 400-750 softskins, a field hospital with all its components, and 4 x LCU carried internally and launched thru gunport door gantry cranes plus 14,000+cz of fuel for the helos etc using just her existing double bottom volume for ballast water.

    That load, BTW, would leave one of your six decks quite empty! Cost roughly AUD350M in 2006 dollars, delivery in 15-18 months if ordered at Daewoo today.

    Oh, before I forget, SEABEE = Sea going barge carrier. There is a current Korean commercial design (unbuilt as yet IIRC) for one of these puppies with a 5000-ton stern lift. Ships like this enable you to carry a vast amount of material in big, boxy barges. Or you can carry those, and a pontoon wharf, and a crane barge to unload them, and a bunch of self-propelled beachable lighters, or a bunch of fully loaded LCU, or a causeway to actually link the ship to the shore.

    If the Britannia hadn’t had the problems it historically did with the Proteus engine, what size market is there for a long range turboprop at this time?

    Any guestimates on the jet thrust needed to get a Brabazon airborne?

    Compared to the C-130J the A400 is larger, and the USAF has a glaring need for lift and volume.

    Given the original C130 was stretched, how confident are Lockheed and the USAF that the C130J will still be the size required in 5, 10 etc years?

    When the designers of the DC-10 and the Tristar were looking at engine placement, did they consider putting all three engines at the tail?

    In the same way, did the 727 and Trident designers look at 2 wing and 1 tail mounted engine?

    However, the US needs Venezuelan oil, and Venezuela needs the US refineries (for technical reasons US refineries are about the only ones regionally that can process Venezuelan oil). The two have an almost unique hostile symbiotic relationship, that has to be based upon pragmatism despite public pronouncements to the contrary.

    🙁

    At the momnet yes, but in a few years….

    from 2007

    http://www.uofaweb.ualberta.ca/chinainstitute/nav03.cfm?nav03=61479&nav02=58460&nav01=57272

    Moreover, it is learned that CNPC will cooperate with the Venezuelan side to build three refineries in China with a total capacity of processing 800,000 barrels of Venezuelan heavy crude per day, which would be likely completed in two or three years.

    Chavez emphasized that Venezuela and China would also establish a joint oil shipping company to carry crude and other products between the two countries, and do business in the Caribbean and take shipments to Africa.

    With these moves, China has become a strategic partner of Venezuela, which will help the country reduce dependence on oil export to the U.S. At present, the U.S is still the biggest oil customer of Venezuela, although oil export to the U.S. has declined from 1.5 million barrels per day in March 2006 to 1.2 million in the first quarter of 2007.

    Chavez said China is set to replace the U.S. as Venezuela’s top oil buyer, as Venezuela plans to raise oil export to China to one million barrels a day by 2012 from its current level of about 150,000 barrels a day. Besides, PdVSA hopes that Chinese oil companies will produce at least 400,000 barrels of crude a day in Venezuela by 2011.

    What the article doesn’t say is that the Chinese are getting the oil at a reduced rate and Venezuela is paying all the extra shipping cost for having the tankers at sea for far longer.

    That video really does show exactly how big the TSR-2 was,

    I agree, stills dont really give the same impression.

    Is PMN1 the same person as PMN?

    Nope, this I am a completely different person with the initials PMN, i had to have the username PMN1 as PMN was taken on the EZ (now Yuku) boards I am also on – important note, if anyone ever hears of this board going to Yuku, be afraid, be very afraid…..:mad:

    Anyway another option, how about on the wings but without pylons as with the DH119 and DH120 proposals and with Concorde?

    Stephen Coontz wrote a book called ‘The Minotaur’ a while back which had an active stealth system – at the end of the book it was due to be fitted into a new aircraft called the Hellcat (which was going to annoy the system’s designer who was a bit of a bible basher).

    Seeing as we seem to be going ET, I read earlier tonight that a stack of UK UFO files are due to be released soon thanks to the FOE act but I cant seem to find the site again at the moment.

    If the original spec DH121 had been proceeded with and the Medway used, where does that leave the Buccaneer and the UK Phantoms?

    Oops, I had forgotten about Lockheed, what got me posting the question was this wiki article (I know I know but it is sometimes useful).:)

    Douglas was lukewarm about the jet airliner project, but believed that the USAF tanker contract would go to two companies for two different aircraft (as several USAF transport contracts in the past had done). In May 1954, the USAF circulated its requirement for 800 jet tankers to Boeing, Douglas, Convair, Fairchild, Lockheed, and Martin. Boeing was already just two months away from having a prototype in the air. Before the year was out, the Air Force had ordered the first of an eventual 808 Boeing KC-135 tankers. Even leaving aside Boeing’s ability to supply a jet tanker promptly, the flying-boom air-to-air refueling system — as first fitted to the KC-97 — was also a Boeing product: developing the KC-135 had been a very safe bet.

    Just four months after issuing the tanker requirement, the USAF ordered 29 KC-135s from Boeing. Donald Douglas was shocked by the rapidity of the decision which, he said, had been made before the competing companies had had time to complete their bids, and protested to Washington, but without success. The U.S. Air Force would buy more than 800 strategic tankers over the next ten years, and every one of them from Boeing. In financial terms, the Boeing 707 would have an armchair ride, while Douglas would be short of cash from that time on.

    In the information I have read on the TSR2, i’ve never come across how many it was planned to order at the start of the programme, does anyone have any information on this?

    Are there any figures for the the number of times a Halifax with a ventral 0.5″ saw a nightfighter closing in from below particularly one fitted with Schrage Musik
