The American weapon designed to fire a nuclear warhead like a shell

That Time the US Military Made an Atomic Cannon · 7:07 · Video: Today I Found Out · Watch at the source

In short: During the early Cold War, the United States developed a massive artillery piece capable of launching nuclear explosives. This video explores the M65 atomic cannon, a weapon of such immense power it was ultimately used more as a psychological deterrent than a practical tool of war.

The M65 atomic cannon was engineered to fire 280mm nuclear-tipped artillery. Its destructive capacity was significant, with a blast power estimated to be approximately equal to that of the Little Boy bomb dropped on Hiroshima.

Despite its engineering, the M65 was only fired once. Following its single test, it served primarily as a deterrent during the early Cold War era, illustrating the era's focus on high-impact weaponry as a means of preventing direct conflict.
