Code Name Trinity: Detonating The World’s First-Ever Nuclear Weapon

What you’re looking at is Jumbo, a 200-ton canister that was designed for the Trinity Test in 1945. While it didn’t end up being used for the project, the then-secret detonation of the first-ever nuclear weapon proved to be a success and marked the beginning of the nuclear age.

The explosion was initially reported as an accidental detonation. The truth was only revealed in the aftermath of the bombings in Japan that signaled the end of World War II. The testing of similar technology has slowed down since the ‘90s due to concerns over the magnitude of the weapons being detonated.
