1970s

Trying to find the earliest year the MiG-21 received the SPS-141 ECM pod, and ASO-2 chaff/flare dispensers. First, for the SPS-141 there is the only the vague 1970s period usually mentioned online. But is there info as to what year exactly did the SPS-141 (SM-1 or SPS-141-100?) became...

The saga of the Royal Navy's carriers after 1966 has been the main focus of interest here, but the workhorse of the RN then as now was the frigate. By the 1970s the RN had plans to replace its Type 12 Leander class frigates with the larger all missile armed Type 22. Leanders were designed...

Although the excellent AH1 Cobra was deployed to Europe in the 1970s and received TOW missiles to help it kill Soviet armour, noone else in NATO could afford it. That left W Germany sticking six HOT missile launchers on its Bo 105 light observation helicopter and the British Army SS11 missiles...

Didn't see anything else here about this already. View: https://www.reddit.com/r/EngineeringPorn/comments/1dtur18/lockheed_loopwheel_testbed_compared_to_a_vehicle/ https://ntrs.nasa.gov/api/citations/19780016310/downloads/19780016310.pdf

Can the Soviets in the 1970s convert a version of An-24 as a night bomber to be used by third world countries. Whose opponents had little or no night fighting capabilities back then

I was curious to see if there had been any drawings of this paper ship plan. Basically a anti sub/ trade lane protector ship for th usn, 20 s-3 in 2 squadrons plus 4-8 small anti snuper aircraft (presumably a-4 but no design specified) and 16 sea kings, to be biult in the 70's to replace the...

I've founds this interesting design on the Shipbucket forums and I've thought I share it here as well. http://www.shipbucket.com/forums/viewtopic.php?t=10014 During the Fourth Defense Force Development Plan (years 1972 – 1976), the Japan Maritime Self-Defense Force (JMSDF) planned to introduce...

Found another interesting document in my files this past weekend – a fairly early (March/April 1975) presentation on the Litton feasibility study for a Spruance-derived AEGIS destroyer that eventually became the DDG 47, then CG 47 Ticonderoga class. At this point, this design was being referred...

Hello all. I have been reading up on Swiss MBT programs and concepts in the last few days and I noticed that Secret Projects does not yet have a thread dedicated to the Panzer 74 proposal. I am aware of the Tank Encyclopedia article on this matter but I thought I'd ask this forum.

As the US looks to go back to the Moon with Artemis my question here is, what might have been feasible in the 1970s to keep the US sending manned expeditions to the Moon? Clearly, the main obstacle was a political one. With no Soviet manned lunar programme once the US had got to the Moon first...

In the 70s, Brazil was slowly trying to develop its space technologies, which resulted to the Brazilian Complete Space Mission (MECB) program and the ill-fated VLS-1, but while digging a bit around it, I found that before deciding on the VLS design circa 1980, there was a period of time of a few...

Althought intrestingly unique vessels and pride of our naval building capacities, the Turunmaa class Gunboat (or corvette in more international sense) never attracted any foreing sales, as didn't anything else we tried to market. Some proposals do have appeared, mostly just with different...

How about a thread on the J-12 ? I noticed that there was none ! It is a jet that I like and I will try to collect in this thread some interesting things about it.

I need your Help in 1970s this kind Wind Turbine was proposed (here illustrated by Roger Leloup in 1976) has some one more information about this ?

Discussion about German corvettes seems to have been popular lately so I'm sharing this Swedish project which I found in Jane's 1972-73. The design was to be a flotilla leader for MTBs or FACs as well as escorts for the remaining destroyer fleet that was then still active. Two were to be built...

Quoted by Gary Paul Johnston and Thomas B. Nelson in "The World's Assault Rifles" - This rather curious and unusual weapon was part of a program during the 1970s to develop a very high rate of fire assault rifle (RFCT: Rifle à Forte Cadence de Tir ). Firing rate experiments were carried out by...
