Hi everyone, We have already discussed a shorter/no Vietnam scenario already so I will not ask for changes related to this. However, what I was wondering about is whether having a second JFK term (due to no assassination) instead of a Johnson term would affect 1963-1968 procurement in any way...

I've thought I collect here the Guided Missile Launcher Systems or GMLS designations the US Armed forces used, mostly the navy but there seems to be many missing launcher designations and sequences.

Hello all. Today I was doing some research into the AGS's LRLAP shells, trying to confirm a hunch I have that the original unit price was drastically lower than the stated $800,000-$1,000,000. I sort of confirmed that, as well as finding information saying the AGS was supposed to fire other...

Hi, from the CIA archive (link) a detailed report about the Verticon project, a photo recce payload to be used with Aerobee rockets.

A few months ago, I posted a thread on a briefing with several more or less obscure frigate concepts for the USN. One of the designs included in that brief is the PXM, which I described at the time as a rabbit hole. This thread is my attempt to chase that rabbit as far as I can go, starting from...

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...
