Atomic Cannon B-Roll Trinity and Beyond 

1:15 that is a good ass representation of how big that mushroom cloud was Also got videos of the audio for the nukes?

When there's an enemy formation out there you really, really don't like.

My favourite test shot, and some great views / angles of the blast.

Lots of footage breaks of the opening scene. I see AEC (now DoE) Albuquerque operations office chief, Carroll Tyler (with the pipe, in khakis and military ball cap), disappear in frames gap. Tyler smoking as nearly always. He probably coughed up oysters every morning. You also see Alvin Graves, Los Alamos testing division boss, in his bomber jacket and white pants, closer to the cannon breech. These cannons were assigned to primarily the Fulda Valley region along East and West Germany, where a likely mass onslaught of Soviet armor would roll through. It’s highly likely these cannon sites would be attacked by Soviet air power before the Soviet armor would rush through. Yet the posturing seemed to have worked. Just one cannon getting off a Mk9 15 kt shell would have been devastating.

NICE! Ive never seen this. Thanks for always posting all the rare footage.

FORE!!! 💥

Double Mushroom cloud... extreme successful shot.

I remember the shot at 1:15 being in the original cut of Trinity and Beyond on VHS (and I think the first DVD edition as well) at the end of the Grable sequence. It was subsequently replaced with a shot of the top of the growing mushroom cloud in later editions. Honestly I prefer the original cut here, as it really gives a sense of the massive scale, even on a relatively low yield test like Grable.

The thing that amazes me is smallish size of the artillery shell and bomb itself has to fit inside the metal casing, plus it had the yield of the Hiroshima bomb. I heard the Atomic Cannon was deemed impractical because it is large and distinctive and the Russians would just follow it around and keep track of its location constantly.

Et puis après c'est propre

Generals: ok good job boys, we're outta here...

15kt - that's Hiroshima equivalent

Será que ainda existem estes projéteis de artilharia nuclear?ou foram todos desmantelados pelos Estados Unidos?

Why does it look like its in direct fire mode

this video would have been better with sound.

Пушка же для 1+ килотонного снаряда. И выстрел снимали , хроника есть.
