I have just heard, via the latest Hawker Association newsletter, that Roy Braybrook passed away last June. Another of the great authors who got me, and probably many on this forum, interested in aircraft has gone to the great aviation library in the sky. He was also, of course, a designer in...

If you think you're spending too much time online, Facebook et al is about to offer (maybe) compelling reasons to spend more. Fortunately, there are still 24 hours in a day, people still need to eat and sleep, and Mr. Zuckerberg and company won't be able to squeeze another dollar out of anyone...

I once read that there were rumors that the DPRK would begin domestic production of a MiG-21 type design in the early 1990s, but those projections obviously never came true. They did assemble MiG-29s from parts supplied by the Soviets and other countries throughout the late 1980s and early to...

Placed here rather than the bar, since it seems that the US Military will be now buying a fair few examples (hopefully at least some bit properly militarised) as part of the Biden administration's government vehicle fleet EV initiative (though I'm a fair bit sceptical myself on how well it will...

The artist Ron Cobb, known for his work for many science fiction movies and TV series, has passed away. :( Source : View: https://twitter.com/TheSpaceshipper/status/1308071692296740864?

The venerable FV432 and M113 troop carriers have been around for more than half a century. I have never seen a realistic comparison of the types from the soldiers' point of view. Anyone know more?

Hi. For some whatever reason, a timely article was pu(bli)shed by Sputnik, a Russian media, dealing with an "old" concept of non-nuclear space-based, orbiting kinetic space-to-ground weapon, sometimes described as "Rods from God"...

In the late 1980s, research started on the new next-generation tank gun. It was quickly determined that it needed to be 140mm calibre. Initially it was to fire the same projectiles as the 120mm gun but at a higher velocity from a similar smoothbore barrel. My question - what was the British...

I must admit to being puzzled at the choice of Dreadnought as a name for the new SSBNs. Assuming 4 or 3 submarines are built, the only rationale is to resurrect the names of our early nuclear boats. That would add Valiant and Warspite and possibly Conqueror or Churchill. The alternative would...
