Original Item. Only One Available. The 90 mm gun M1/M2/M3 was an American heavy anti-aircraft and anti-tank gun, playing a role similar to the German 8.8cm Flak 18. 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).

The projectile consists of a hollow steel forging with a boat tailed base and a streamlined ogive, and may be either the normal fuze cavity or deep cavity type. It is loaded with 2.15 pounds of Comp B (1.68 pounds, deep cavity) or 2.15 pounds of TNT (1.6 pounds, deep cavity). Some earlier rounds are loaded with 50-50 amatol and a booster surround of a small amount of TNT. The supplementary charge consists of 0.3 pounds of TNT. Most deep cavity projectiles are assembled with supplementary charge, spacers, and closing plug; however, some rounds of earlier manufacture were assembled with supplementary charge and PD fuzes or unfused without supplementary charge but fitted with a closing plug.
