It had a 3.5 in (90 mm) diameter bore, and a 50 caliber barrel, giving it a length of 15 ft (4.6 m). It was capable of firing a 3.5 in × 23.6 in (90 mm × 600 mm) shell 62,474 ft (19,042 m) horizontally, or a maximum altitude of 43,500 ft (13,300 m).\u003c\/p\u003e\n\u003cp\u003eThe 90 mm gun was the US Army's primary heavy anti-aircraft gun from just prior to the opening of World War II into 1946, complemented by small numbers of the much larger 120 mm M1 gun. Both were widely deployed in the United States postwar as the Cold War presented a perceived threat from Soviet bombers. The anti-aircraft guns were phased out in the middle 1950s as their role was taken over by surface-to-air missiles such as the MIM-3 Nike Ajax.\u003c\/p\u003e\n\u003cp\u003eAs a tank gun it was the main weapon of the M36 tank destroyer and M26 Pershing tank, as well as a number of post-war tanks like the M56 Scorpion. It was also briefly deployed 1943–1946 as a coast defense weapon with the United States Army Coast Artillery Corps. Each gun cost roughly $50,000 to make in 1940 and utilized up to 30 separate contractors to manufacture.\u003c\/p\u003e\n\u003cp\u003eThe bottom of the brass casing is stamped:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e90MM M19\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eLOT 6268-16-F.A. 1941\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe projectile is crimped onto the shell casing and is not currently removable.
