Where was Atomic Annie fired?
On May 25, 1953, during the Operation Upshot-Knothole test series at the Nevada Test Site, now known at the Nevada National Security Site (NNSS), a milestone occurred in ordnance development. A 280-mm cannon, nicknamed Atomic Annie, fired the first and last nuclear projectile as part of the Grable test.
What is the smallest nuke ever made?
The W54 (also known as the Mark 54 or B54) was a tactical nuclear warhead developed by the United States in the late 1950s. The weapon is notable for being the smallest nuclear weapon in both size and yield to have entered US service.
What is the 280mm motorized heavy gun?
For the U.S. Army, prior to the refinement of tactical nuclear missiles, that meant developing an atomic artillery piece. This weapon was the M65 280mm Motorized Heavy Gun, also known as the Atomic Cannon. In May of 1950, the Watervliet Arsenal began designing the 280mm Gun T131 for the U.S. Army.
What is the 280mm projectile gun T131?
In May of 1950, the Watervliet Arsenal began designing the 280mm Gun T131 for the U.S. Army. This heavy, mobile, long-range gun was developed to fire the W-9 15 kiloton atomic 280mm Projectile T124.
What is the history of the Atomic Cannon?

How many atomic cannons are still in use?
Adopted in 1956, the cannon could fire both nuclear and conventional shells over a range of 18 miles. Rendered obsolete by the development of more mobile rockets, the atomic cannon was withdrawn from service in the U.S. Army by the mid 1960s. Only 8 cannons remain today.
