late 1960s

In 1966, the Maritime Administration began design work on a general purpose cargo-liner to be built in large enough numbers to be useful in national emergencies and replace war-era vessels serving in non-subsidized trade, with the idea that they be designed for minimum cost. As specified in a...

How about a thread on the J-12 ? I noticed that there was none ! It is a jet that I like very much and I will try to collect in this thread some interesting things about it. I started to work with Inkscape and I hope to make color profiles of J-12 under the roundels of countries where it could...

The story of how in 1968 the universal dynamic protection for the Object 775 and T-64A tanks was developed and tested, surpassing all subsequent developments of the Research Institute of Steel - "Contact" and "Contact-5". This page of the history of tank building is not mentioned anywhere...

Just bought the 1968/9 and 1969/70 Jane's Fighting Ships and found two interesting West German naval projects which were planned for the 1970s but were different from the final vessels. The first is for 16 missile equipped fast patrol boats. These would carry the Tartar missile system in...

I have been looking for the attached picture for years and found it in the US Navy section of Jane's Fighting Ships 1969/70 . It shows the range of guns planned for US service in the 1970s. From left to right we have: 8 inch Major Calibre Lightweight Gun (MCLWG). 5 inch 54cal Mk 42 gun for DD931...

The story began in 1969 in the Sino-Soviet border conflict，Chinese captured a T-62，At that time, all their anti-tank weapons were unable to effectively destroy the T62. So Armor troops think they need a new second-generation tank，call “122”（The Type 69 "121 that was being developed at the time...

I came across this project in a 1968 United States Atomic Energy Commission booklet, The ATOM and the OCEAN, by E. W. Seabrook Hull (can be found on Project Gutenberg here). The National Science Foundation had proposed an Arctic Drift Barge for Arctic research, which would have a nuclear plant...

The year 1968 will always be remembered for its upheavels. But it also saw Nixon elected in the USA and the Breshnev doctrine crush new thinking in Eastern Europe. Alternative departures from real history in 1968 could go either way. The toymaker Marx went so far as to make a President Hubert...

Hello guys, i dont mean to bother you, but i found the mentioning of the Short Skyvan being modified for COIN operations and also receiving a modification/variant of the Sea Cat missile called "hellcat" (that i couldn't even find a single picture), do any of you have info of this "Counter...

In "Storia Militare" n. 196 (January 2010) Enrico Cernuschi described the unknown project of an early Italian helicopter/VTOL carrier of 60's. During 1965 the Italian Navy seriously considered the possibility to modify the proposed second "Vittorio Veneto" cruiser into a sort of small carrier...

This is a new one to me. I've searched the forum and could not find much if anything on it, so I am posting a new topic dedicated to the Convair 660, a short-haul twin-jet. (Please remove or combine with another appropriate topic, if it already exists). The model photos (and artistic rendering)...

G'day gents Just been reading an extract from The Bradley and How It Got That Way: Technology, Institutions, and the Problem of Mechanized Infantry in the United States Army by by W. Blair Haworth I found it interesting that "The U.S. Army Tank Automotive Command (TACOM) conducted a...

I know this is a well covered subject but I was wondering if there is anywhere an RN document from 1965 or 1966 showing what its planned 1975 or so carrier fleet was supposed to look like. Based on what has been posted here already here is a stab at what I think was intended Fleet Carriers...

G'day Gents! Once again I've been flicking through one of my favourite books “The Pentagon Paradox. The development of the F-18 Hornet” by James Perry Stevenson (ISBN 1557507759), Shrewsbury, 1993. In this book it talks about the following program: 'Commander Ernie Waller USN’s theoretical...

At some point during the late 1960s, the Goodyear company studied the possibility of a new giant rectangular transport airship category which they called "Dynastat". Source: AERIAL VERY HEAVY LIFT CONCEPTS FOR THE 1990 ARMY VOLUME III - ACADEMIC & INDUSTRIAL PRESENTATIONS (U.S. Army, November...

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...
