late 1950s

I've seen several sites claim that in 1956, the USSR tried to provide the R-2 missile with an RDS-4 fission warhead. The words experimented and tested are used, but I've never seen any photo, diagram, or a sourced history of this brief project and I'd love to know more. Testing this warhead on...

What happens if the Bristol T.188 research aircraft doesn't underperform? What happens if it flies upto Mach 2.8 and reaches the thermal limit of the windscreen? We now know that it's underperformance is related to lack of interest and investment in the Gyron Junior engines after the...

A little illustration I did depicting a Boeing Model 702 concept - this was a 1950s effort at defining an eventual B-52 replacement, with this iteration having four engines on pylons and a further quartet in nacelles built into the underside of the wing. Scott Lowther's "US Supersonic Bomber...
