Testing Nuclear Artillery

While it was not the highest yield atomic bomb in existence, the arms race was in high gear. The United States developed a lot of low-yield, short-range nuclear weapons. However, this was the only one that it ever tested. The Upshot-Knothole Grable nuclear weapons test-launched an 11-inch projectile in the air for 19 seconds on May 25, 1953. Upon its landing, it had a blast radius of 6.2 miles or so. The 15-kiloton bomb had around the same yield that Little Boy had in Hiroshima, but it was much smaller.
