    Rover Turboprops

    Rover developed gas turbines for automotive applications, development continued after the marque's absorption by Leyland in 1967. In addition to automotive applications Rover also produced gas turbines for APU applications, as described here. They also went as far as testing them in aircraft...

    Leopard 2 prototypes

    During the development of Leopard 2, about seventeen different hulls (PT series) and turrets (T series) were built. At least two of the hulls (numbered PT11 and PT17) were fitted with hydropneumatic suspension and only six roadwheels. I managed to find only one small picture of such hull...

    Impact on the Iran-Iraq War if Iran had bought A-10s

    If Iran had bought the A-10 in sufficient numbers, they had been delivered and entered service, what, if any, impact would they have had on the course of the Iran-Iraq war? Chris

    Fliegerfaust for Mijaheddyn?

    Some time ago, it must have been in 2013-2014, I was able to see in a movie (maybe on YouTube) a guerrilla with the typical Chitral cap used by ethnic Afghans Pashtun, equipped with a weapon system that looked like a German Fliegerfaust / Luftfaust and the militian who used it pointed it...

    Grumman / Shin Meiwa ASR-544-4

    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...

    General Dynamics Fort Worth F-16 derived GAU-8 gunship concept (G.F.G) from 1976

    Thanks to Air21 over at What If Modelers: Thought this design was already mentioned in an existing SPF thread, but I couldn't locate it. I'm wondering if this design originally grew out of one of the 'Model 402' studies. Also, I wonder if there was a late 1970s semi-official USAF requirement...

    MIAG (Mechanized Infantry Assault Gun) - MICV-70 derived assault gun proposal

    An excerpt: Note: Given the date and lack of dismounts among other things, I suspect that this was the early incarnation of the MIAG proposal. EDIT: Ack, blundered on the title! I put down MIVC-70 instead of MICV-70 and only noticed it now!

    FIGAT (FIberGlass Aerial Target) USAF and USN tow targets

    I recently happened on a photo of a U.S. Navy tow target which I hadn't previously seen. Linked from the VC-2 squadron page of the A-4 Skyhawk Association website, it was accompanied by no explanatory text, only a short caption saying "1974: Ed Jennings tells us about the "FIGAT". As I was...

    Saab Viggen concepts and unbuilt versions

    Is there anywhere in this fine forum which gives more indepth information into the proposed Saab 37E and Saab 37X variants of the Viggen? The Saab 37E was proposed as a Lockheed F-104 replacement for European NATO airforces in 1975; While the Saab 37X was proposed to Norway in 1967–68. Ive...

    Stealth Aircraft designs of the 1970s - A speculative question

    This is a spin-off of my Fictional Warships thread. The most recent novel I have added is "Poseidon's Shadow" by A . P. Kobryn, a 1979 technothriller which has a brief appearance by a stealthy successor to the SR-71 'Blackbird' which the novel describes as a "...distant predecessor..." It's...

    Secret Flight Test History - An Alternate History of the X-24C

    This is just a little thought exercise in a 'what-if' scenario for a hypersonic flight research program. The US efforts to develop a hypersonic aircraft design in the 1950's (Aerospaceplace, X-15), 1960's (X-20, Lifting Bodies), and 1970's (X-24C, HYFAC) culminated, for a time, in the USAF and...

    NATO Standard Tank for the 60s and 70s: Which would you choose?

    As we know the Russians managed to standardise their tanks forces in the 60s and 70s on two designs: The T55 and later the T72. What tank should NATO have chosen if politics had been no object?

    Help needed identifying unknown SPAAG prototype

    G’day gents I’ve stumbled across this web site http://doktorkurgan.livejournal.com/36798.html?thread=61630 which depicts a prototype (in 1977) SPAAG, which from what I can make out (via translation), combines a 25mm cannon, with the chassis of the XM-701 MICV! It appears it’s a response to the...
