late 1970s

Once upon a time there were only two sides, (and you knew what to expect) and there was a country called the Soviet Union. And the aircraft carrier was the dominant species on the seas (The bigger the aircraft carrier was, and the happier the admirals were), but this kind of ships are very...

From 1979 to 1980, the United States Navy proposed updating their remaining obsolete FRAM Gearing class destroyers in the Naval Reserve Force as escorts to protect trans-Atlantic convoys against Soviet submarines. Some of the proposed modernization included replacing the WWII-era 5"/38 twin-gun...

HM-45 tank. It was a deep modernisation of the T-54 and T-55 tanks proposed by the Polish industry in the second half of the 1970s - comparable to the PT-91 (compared to the T-72) in terms of the scope of changes. It was abandoned by the Ministry of National Defence in favour of the USSR...

Happen to see this weird shoulder fired recoilless launcher several months ago, named Speer, 75mm caliber smoothbore. When looking for infos in Rheinmetall weapon handbook 1977, found this, Hellebarde, a vehicle mounted weapon, Düsenkanone=recoilless gun. Same caliber, similar effective range...

I was looking at the SDASM flickr pictures dump and found a Huey modified with retractable skids, ostensibly to afford a 360 degrees field of view to the large rectangular antenna mounted on the bottom of the cabin. I was not aware of such installation. It reminds me of the FOPEN radar...

Future Soviet tank project “Object 490 Poplar” was under development by Eugenie Morozov's team from the end of 70-th up to the end of 80-s. The main features of the “Object 490” were: - crew consisting of two people - commander-gunner and driver. Reduce the crew to two people and place them in...

Hi, http://archive.aviationweek.com/image/spread/19790305/20/2

In the late 1970s, it was planned to modernize the Alany class CGs for service through the 1980s. The Albany class were full guided missile conversions of WWII era Baltimore and Oregon City class heavy cruisers. Eventually the funds allocated were diverted and the ships were decommissioned...

From Sealordlawrence's post on MBT-80 I would add that at this point the British Army was also scheming 1,900 MICV's (which were originally meant to have Chobham armour and a 750hp engine with a total weight of 30 tons). MBT-80 was apparently cancelled in July 1980, it seems that prior to this...

I seem to recall before they bought more Leanders the RNZN considered a serious conversion of their Type 12 Otago. I am sure I have seen a drawing but cannot remember where? It would make an interesting add on to my UK frigates stuff.

I've been researching the Westland WG 30 helicopter project from the 1980,s. Got a fair bit of information but can anyone supply any more please ? Everything welcome. Thanks.

Hi all, can you translate or name this three projects(?)... Thanks Maveric

I’m looking for any copies of a picture of a self propelled RBS 70 turret developed in Sweden in the 1980s. It was marketed widely but with no takes and I can’t find any pictures of it around the place now. This was a fully armoured turret with all the RBS 70 guidance equipment inside and a...

Hi, hear is the Lear design,Fan 2100,in early model,it had many differents. http://www.flightglobal.com/pdfarchive/view/1977/1977%20-%203794.html

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...
