ARMED FORCES DAY
19 May 1956
I do not know which base on Okinawa these were taken but you will see C-124 troop carriers, Marine helicopters, F-86 jets, F-84 jets, Air Force helicopters and the "Atomic Cannon".
The M65 Atomic Cannon, often called Atomic Annie, was a towed artillery piece built by the United States and capable of firing a nuclear device. It was developed in the early 1950s and fielded by 1953 in the European and Korean theaters. The total weight was 83 tons, and it was 84 feet long. It fired a 280mm nuclear device about 20 miles.
