From the early 1950s the US began developing nuclear artillery. The first was the Honest John missile with a range of 15 miles and a W7 nuclear warhead with a yield of 20 kilotons. There was also the M65 Atomic Cannon delivering 280mm nuclear shells with yields of 15 to 20 kilotons. Both date from 1953.
The first M65 was named Atomic Annie. On May 25, 1953, Annie fired an MK-9 atomic shell. It flew seven miles before exploding at a height of 524 feet above the ground.
Later systems included the Corporal missile, the M110 and M115 howitzers and the Davy Crockett missile. The Davy Crockett had a disconcerting [to its users] range of only 1.25 to 2.5 miles and a yield equivalent to 10-20 tons of TNT.
The weapons were intended for US use in the western European battlefield. Other countries also developed nuclear artillery.
Most of the training for the US systems appears to have been done at the Fort Sill Artillery School in Oklahoma. The Atomic Artillery Weapons Effects Computer shown below may have been produced there. A October 1958 school publication mentions the computer as being available from the Army Artillery and Missile School Bookstore.
The computer consists of three disks with two cursors. It is 14″ [355mm] in diameter and is made of some stiff material [probably card].
