This gun was presented in 1992. The ammunition could have the same performances as the 45mm comvat: 1.095kg HE shell with a muzzle velocity of 1100ms. Rate of fire is 400spm.

Triggered by the Lippisch developments, that were tested with the X-113 on Lake Constance, Dornier started research in that field during the 1970s, too, called "Stauflügelgerät" (. One project for a commercial transport was the P.477 for up to 27 passengers. Another one, desigantion unknown...

This was a US Coastguard project from around the early '70's: http://www.dtic.mil/dtic/tr/fulltext/u2/755767.pdf

I've done a search. and I'm surprised that there's no thread for this... Following the partial replacement, in 1959, of the British Ministry of Supply by the Ministry of Aviation, the iconic 'Rainbow Code' system for projects was also replaced, by a new system of two letters, and three numbers...

I am trying to get to the truth behind the story about the Type 42 ending up with a hull shorter than the designers wanted. The sources that I have available are contradictory. Norman Friedman states that there is no indication that the Type 42 was shortened from the a preferred 434ft (the...

The Houston AIAA section has published a 4-page article I put together on the Conroy "Virtus," a twin-fuselage heavy lift aircraft built from B-52 parts meant to serve as the Space Shuttle Carrier Aircraft. You can download it (in the March/April 2012 issue of Horizons) for free here...

I thought it might be helpful to tease out this aspect from the British centric discussion. Originally the West Germans intended to replace their M48s with the MBT 70, a joint production with the United States which ground to a halt because of complexity and high cost. German sources on the...

The Challenger tank was arguably born in about 1970 when the UK, impressed by the performance of their BURLINGTON (Chobham) armour, but concerned that a wholly new MBT would not be in service before about 1985, proposed the development of a near-term improved tank using some existing components...

An earlier thread by me on amphibious shipping got well and truly trashed into a discussion on the merits of the Scimitar! Never mind, here goes, this is purely for info. I found a cutting from an old Maritime Naval mag in the 80s which showed a Swan Hunter design for a LPH looking like a...

Over the years NASA has run various systems engineering courses with universities around the United States. In the mid-1970 a group associated with Rice University was asked to design a Dual-Mode rover for use in the 1980's. The selected design was for a two man, tracked rover. Manned/Unmanned...

In this months Spaceflight, there is an article on Starships of the Future (mostly Daedalus and Icarus) that mentions a suggestion by G H Stein published in Analog, October 1973 called "A Program for Star Flight". 'A full program of exploration was proposed which would utilise a fleet of no...

The space shuttle project thread, http://www.secretprojects.co.uk/forum/index.php/topic,1928.0, had a brief discussion of ideas to put passenger modules in the cargo bay. I thought it might be interesting to try and capture some more details in a separate thread. I believe some concepts were...

To reply no. 55 by Aerofranz, I misidentified the illustration's top sensor carrier as the Bell SeaPig. It's actually the SeaKat, still from Bell Aerospace. I apologize for the error. Attached are a couple views of a SeaKat factory model. I would be grateful for any info about this little-known...
