The Atomic Cannon, at 280 mm, was the largest nuclear weapons capable mobile artillery piece manufactured by the United States. On May 25, 1953, a 280 mm cannon fired an atomic projectile a distance of 7 miles at the Nevada Test Site. The test known as "Grable," exploded with a force of 15 kilotons, similiar to that of Hiroshima. Twenty 280 mm cannons were manufactured. None were used in battle. Sequence from the HD version of "Trinity and Beyond - The Atomic Bomb Movie" available on blu-ray.

  • The cameras are mounted on 17ft high tripods which are designed to withstand the force of the shockwave (at 5-10 psi).

  • is there anywhere i can get this without a watermark or text for cinematic purposes?

  • @ThisIsntMyTaco this is from "Trinity and Beyond" and can be purchased on blu ray on atomcentralstore or Amazon or purchased for download on itunes, netflix etc.

  • question: Before the cannon fires the shell there is already a dustcloud/smoke present to the right of the intended point of impact. (Like there has been an explosion prior)

    What is that?

  • @StrangeDeimos there are rocket trails and a smoke screen experiment going on at the intended burst point. The smoke rocket trails make the shockwave more visible.

  • @neurel111 To clarify this sound is added in by the editors of the film. Quite common.

  • @neurel111 No, it's real alright. The sound is added in because back then movie film cameras did not come with sound. You wanted sound you brought a separate recorder.

  • @CL137626 oh I thought it was an animal but not sure.. now I`m sure :D

  • What causes the big flash?

  • @deiu9999 Pigs. 

  • @neurel111 No, they just added sound effects.

  • @StrangeDeimos

    I bet they had armored vehicles there, footage is probably still classified
