late 1970s

The IKL/HDW T.2000 was rated the highest on the initial tender submission but it would be wrong to say it was more developed than the winning Kockums T.471. For example the T.2000 would have needed more modification to carry the US technology Rockwell combat system than the T.471. The T.471 also...

Once again everybody I bow down to your wisdom and plead for enlightenment! Having spent an afternoon randomly googling (I really enjoy my current job ;)) I stumbled across the RB.431 entrance on the Skomer site. http://www.skomer.u-net.com/projects/turbines.htm It claims that the engine was...

Many years ago in the 70s I bought a boardgame called Red Star White Star about a hypothetical mid-70s war between US/West German units and Russian forces. The counters had neat silhouettes of M60s and Sheridans for the US and Leopards for the Germans. Seeing the thread on MBT 70 reminded me...

Hi, In 1985 the Northrop designed a new project called F-5S (by that time),it was proposed as a version of F-5G (F-20) for Sweden, with 30 percent larger wing,do you know it ?.

As a happy new owner of AMT/ERTL F-15 ASAT 'Satellite Killer' in 1/72 I will appreciate any photographic/graphic references of ASM-135 missile and its F-15 carriers. Thank you!

Came across the following in Air International. Seven companies responded to the VFAX RFP for unfunded proposals for a Mach 1.6 aircraft with 28,000-30000lb weight an unit cost less that $6 million in 1975 dollars over a 400 aircraft program. General Dynamics submitted two designs; a...

Sweden looked at a number of MBT concepts in the 1980's as a replacement for the stridsvagn-103. Key ones were UDES-11, UDES-17, UDES-19 and Stridsvagne 2000. A UDES-3 has been mentioned and appears to be a prof of concept vehcile based on the marder - with a bofors external mounted gun. not to...

Interesting front engined MBT proposal for the Swiss Army, the NKPz ended up to expensive and the auto loader was apparently problematic.

This extraordinary mockup(?) of a Westland WG.33 coaxial helicopter dates from 1979. Looking for more information. SOURCE: http://avia.russian.ee/vertigo/westland.html

The B83 was allocated SKr 400 Million in 1977 for initial development. It was expected to arm the B3LA light fighter design, but was clearly adaptable to other designs. It used an imaging infra-red (IIR) seeker working in the 7-14 micron band and based on the seeker of the cancelled RB72 AAM. In...

AST (Air Staff Target) 1227 was a requirement for a PGM for antitank duties. BAe offered the highly supersonic Sabre, based on the Rapier SAM airframe with a laser seeker. Bill Gunston suggests the seeker was by Martin Marietta and related to the Copperhead seeker. Single shot kill probability...
