Hi, The Kyushu J7W2 single seat jet interceptor project.

Just wondering if anyone knows what the tested maximum altitude and speed of the A-12/SR71 was? I contacted the USAF recently and they simply stuck to the published figures saying it flew at 85,000ft and could reach Mach 3.3. This doesn't seem to make sense as variants of the F-4, F-104 and...

Ryan VTOL fighter project of the late 1950's. From Japanese Magazine "The Aviation Magazine" September 1958.

Some time ago, I found this pics in http://legion.wplus.net. It was a soviet project for an AWACS based on a jet powered version of the Tu-114 airliner. In fact, it should be considered a jet powered Tu-126 "Moss" AWACS. Sadly, the page is in russian. Any aditional info (and drawings) should be...

The preferred UK AEW for the RAF was always the Nimrod as it was big and in production. In 1966 studies looked at various radar options, but lack of money delayed it. All of the above comes from 'Airborne Early Warning, design, development and operations' by Mike Hirst, Osprey, 1983.

I'm still working on the text, in the meantime, enjoy some pics. Plan view is ALR Piranha 4, with additional side view of Piranha 2D and scrap view of two seat nose.

When the UK decided to develop an AEW version of the Nimrod, was there any attempt to make a copy of the Hawkeye and Sentry but with British developed mast mounted rotating radar and computers or did the designers go straight to the fore and aft mounted radars? There is an interesting history...

Lockheed SR-71/YF-12 Blackbirds Excellent volume in the Warbird Tech series, good solid information from a good author. Recommended. ****

Hello all I am looking for information, drawings (including 3-views) and specifications for North American Aviation’s ‘Retaliator’ and the NR-349 Interceptor proposals. These were based on the A-5 Vigilante carrier-based strike-bomber Regards Pioneer

This radar formed the basis of the AWG-9, and was the first lookdown/shootdown weapons system. Originally developed for the North American F-108 interceptor, the origins of AN/ASG-18 lie in 1954, when alongside a new interceptor competition a competition was held to design a radar with a 100nm...

To my shame, this is the first time when I see La-250 in flight.

This is Red Queen, re the website in RP1's post. should it be a new thread? These pics are I suppose the mock up. I have seen another photo of Red Queen, I think in Ian Hogg's book on AA artillery.

I found out some information about Britain's embroynic ABM system designed in the 1950s. The Ministry of Supply in 1954 placed study contracts with English Electric and Marconi to develop a ballistic missile defence. In February 1955 this led to Air Staff Target AST 1135. The entire programme...

In AJ Jackson's book Avro Aircraft since 1908 reference is made to a predecessor design to the CF-105 Arrow that would have used two stacked turbojet engines (like the EE Lightning), a swept delta wing and conventional tailplane. This is the first I've heard of such a proposal and am wondering...

One proposed Lockheed S-3 Viking variant that never really progressed was an airborne early warning/AWACS variant of the S-3 that would have replaced the E-2 Hawkeyes on carrier decks. Models have been built and there's been manufacturer's artwork, but I've never come across anything more than...

I was reading a little about the Avro Canada CF-100 on the net yesterday, and came across reference to a proposed CF-103 program. It stated that the CF-103 was a refined and swept wing development of the CF-100, when the CF-105 Arrow was unfortunately cancelled. The article stated that only a...

I know following projects: Grumman G-89--------XS2F-1 Vought V-368---------XS2U-1 Lockheed TDN L-192-6 Curtiss-Wright Model ? And that can tell about other competitors?

In view of the material already presented in the forum this topic will surely motivate enough crossposting but I believe that the topic deserves to take their own place. -A 90's proposal of GE for a Super-AWACS. A wind tunnel model existed but I have not gotten pictures of the same one.

USAF ‘Improved Manned Interceptor’ (IMI) Program On 9 February 1968, the Defence Department announced they were not going to purchase the Lockheed F-12A interceptor (later the SR-71), opting instead to remain with the F-106 as the primary interceptor to protect the continental USA from air...
