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

On 20.5.1952, Ministry of Defense industry of USSR organized a meeting with tank constructors and with the marshal of tank forces, I.S.Bogdanov, to discuss the future of armored forces development. The result of this meeting was a set of tank requirements from 18.6.1952. The resulting tank was...

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...

In early 1970, the Aussies sent a request to Saab that they wanted to procure the in-development fighter variant of the Saab 37 Viggen (JA 37) as a replacement for their aging Mirage III. Saab got green light for export and sent classified preliminary documentation in December 1970. Swedish...

I've found 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 a...

I' ve long been fascinated with the idea of "pivoting" cars from oil & fossil fuels to ammonia. In an alternate word: in the 1970's. A time when electric cars weren't ready by a very long shot. Methanol could be an alternative, but screw carbon, and let's go ammonia (even if NOx might be a...

It is known that originally the 4th member of the Kitty Hawk class carriers the USS John F. Kennedy were to be nuclear powered variant of that class and would had been the 2nd nuclear carrier in the USN and in the world using a new Westinghouse A3W reactor design though there were plans to build...

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.

An early model, the G-303-1, I believe of the late 60's VFAX program featured canted outward vertical stabilizers like the YF-17 and F/A-18 family This feature was dropped in the later VFX program that resulted in the F-14 does anyone have an idea as to why and also what would be the effect...

I'm looking for information, particularly technical specifications, of the Viper Mk 633-47 afterburning turbojet. This was developed for use on the Yugoslav J-22 and Romanian IAR-93 aircraft. It appears to be a Viper Mk 632, as licence produced in Yugoslavia, but obviously fitted with a newly...

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...
