Little David - 914 mm Mortar

Little David was the nickname of an American 36 inch (914 mm) caliber mortar used for test firing bombs during World War II. Towards the end of the war it was modified to serve as a siege mortar, as it was expected that the US forces would encounter extremely strong fortifications during the invasion of Japan. The invasion became unnecessary when Japan surrendered and Little David was never used in combat.


The mobile mortar was capable of hurling a 3,650-pound projectile a distance of six miles. The giant mortar had a rifled, 22-foot, muzzle-loading tube which, with its firing mechanism and other parts making up the tube assembly, weighs approximately 80,000 pounds. The mortar's base assembly, on which the tube rests, is constructed like a huge box and weighs 93,000 pounds.



Unique T1-HE shell with a long conical nose weighed 1678 kg (3700 lb) of which 726 kg (1600 lb) occurred in the explosive.
