I'm trying to find any record of RAF/Coastal Command of the Ford-built B-24H. Thus far I've found small references to B-24H-15-FO 42-52776 going to the RAF as VB904. Also, B-24H-20-FO 42-94797 being drawn from USAAF stocks in the UK to the RAF as Liberator B.IV TT340. Any info on either of...

Hi. I'm looking for information on the SC-21 COEA studies, particularly the Battle Force Combatant (BFC). I did some digging around on the web, and it was supposed to replace all the Knox and Perry-class frigates, and according to an FAS page, this meant an estimated 104 of them would be built...

Whenever I look at my little model of the USS Long Beach nuclear missile cruiser I find myself musing what a 21st Century version for Western navies could look like? Such a ship would replace the Ticonderoga class in the US Navy and perhaps provide Task Force escorts for the RN and MN instead...

Something that's always struck me as odd was the lack of longer range RIM-67s on these nuclear powered Frigates/Cruisers, was it simply cost cutting or was there a deeper philosophy behind their design?

Fincantieri win the USN competition for the new frigate, 7,400t ship, HED propulsion, 16/17 knots cruise, 6,000 nm range ship, the GD/Navantia F100/Hobart variant, the Austal Independence LCS variant and unknown Ingalls design, they never released any info, lost out. USN budgeting $1,281...

Something different for today ... a collaborative project between Grumman and Shin Meiwa in Japan. Note wing engines can tilt up a few degrees (it's described on another page). Also, there is heavy reliance on active boundary layer control via twin turbines behind the rear pressure bulkhead...

ABC News: "Hunter class frigates will be built by BAE in Australia — but what can the warships do and why do we need them?" http://www.abc.net.au/news/2018-06-29/hunter-frigate-build-bae-what-you-need-to-know/9923912

Some time ago, we managed (thanks to JFC Fuller) to get some decent info on the proposed 1962 Royal navy Escort Cruiser https://www.secretprojects.co.uk/forum/index.php/topic,1600.msg184219.html#msg184219 Unfortunately as so often the thread go sidelined into discussions on launcher...

From Grumman Aircraft since 1929, here is a Grumman designs 137,142,165 and 215,all develop from S2,and remained a Projects.

1983, rather than 1982 is a key date for decisions for the RN and UK defence as a whole, in the light of the Falklands and it's effect not just on defence thinking but on the UK populace's attitude to their country. As surely as it was to the political establishment. But in terms of changes a...

I am utterly confused about the original French plans for the deployment of this missile, the wiki page for the Suffren class destroyers states that six ships were originally planned and that this became two batches of three (the second tentative?) then just two ships when the money for the...

I know this subject has been done to death but can indulgent readers please remind me of the answers: Why was the Royal Navy so keen on a Hermes sized carrier when the size of NA37 Buccaneer should have made it clear that only Ark Royal, Eagle and Victorious were big enough to ship 60s...

I came across the Saro P.200 brochure at Kew and a file of related correspondence. The P.200 was designed in 1957 to meet an Admiralty requirement. The hull was a normal planing bow with a tunnel aft to carry a Pentane A/S homing torpedo. The hydrofoils and rudders were separated to allow the...

Anyone have any more information about dimensions and speed of this 1937 Italian sub hunter of 1300 tons with anti-submarine float plane? Love to know more about the floatplane. 3x1 120mm; 4x1 20mm; 2x2 torpedo tubes; 4 depth charge throwers, and sonar...

The usual crew of retired military and political types are warning that the UK is not able to meet its defence requirements with the present budget and kit. Given the collective expertise on this board what advice would you give the Prime Minister who takes over in May after the election? I...
