Four Boeing tactical fighter designs. Hard to figure them as tactical....

The other day I was looking at some space proposals from the past and I stumbled upon this beautiful SSTO. I have only been able to find one source that gave some details about it and I'm very much hoping that you guys can help get more details/drawings on this proposal. "The ”Windjammer”...

Back in the 1960s Boeing was telling everyone that its Supersonic 2707 transport would be the must-have airliner for the 1970s. Some 26 airlines took out options on the plane. There is a comprehensive thread about the US designs on this site, but no illustrations of the artwork Boeing must have...

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...

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...

Hi, here is a hydrogen-powered airliner Project,designed by BAC. L+K 15/1978

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

Good Day All - On EPay - artwork for the proposed KC-747: https://www.ebay.com/itm/Vintage-USAF-Boeing-Military-KC-747-Advanced-Tanker-Aircraft-8X10-Concept-Art/283427464849?hash=item41fd97e691:g:BGoAAOSw35pclbdS There is also a brochure on the proposal...

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...

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...

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...

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!

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...

Good Day All - Some non aircraft/missile drawings from the Vought Archives of a proposed TACV - Track Air Cushion Vehicle. Apparently there as a model similar to this design shown at Transpo '72. An article on the similar (but built) Rohr TACV is at...

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...

The first of the "Thousand Astronomical Unit" space probes designed from the late 70's into the 80's. Nuclear electric propulsion would send the craft on a fifty-year mission into interplanetary space to test technologies for a future true interstellar mission, for deep-space science and to map...
