<h2>Armament</h2><p>M32 Cannon used on M41 light tanks.</p><h2>Development</h2><p>The 76 mm AP-T M339 was originally developed for the 76 mm M1 series of guns used on the M4 Sherman tank series and the M18 gun motor carriage. Later developments from 1947 onwards led to the 76 mm M32 gun for the M41 Walker Bulldog light tank series, the first of which was produced during 1951. The 76 mm AP-T M339 is intended for use against armoured targets but is generally regarded as obsolete and is now rarely encountered. This round is no longer in the US inventory.</p><h2>Description</h2><p>The 76 mm AP-T M339 (actual calibre is 76.2 mm) is a fixed round with the projectile crimped to the brass or steel cartridge case. One unusual feature of this round, and the other rounds in the US 76 mm series, is that the case is crimped over the projectile's specially designed drive band which has a groove to accept the cartridge case crimp. The 76 mm AP-T M339 projectile is a solid tungsten carbide slug, with a relatively short ogive, covered by a lightweight windshield to provide a better ballistic shape. A red M13 tracer is located in the base of the projectile for ignition by propellant gases; it burns for approximately 3 seconds. On impact with a target the windshield crumples to allow the tungsten carbide projectile to penetrate the armour using kinetic energy alone. The cartridge case may either be an M88 (brass) or M88B1 (lacquered steel). The base-mounted percussion primer is the M58 containing 25.9 g of black powder. The propelling charge is 2.54 kg of M30 propellant. Muzzle velocity is 954 m/s and maximum range 14,700 m. The training round for the 76 mm AP-T M339 is the 76 mm TP-T M340 or M340A1. This round is virtually identical to the M339 in most respects other than the projectile body is of mild steel and therefore has only a limited armour penetration capability. The 76 mm TP-T M340 uses a brass M88 cartridge case and an M5A2B1 tracer, while the M340A1 uses a lacquered steel M88B1 case and an M13 tracer.</p><h2>Authorised fuzes</h2><p>None involved Equivalent rounds TURKEY</p><p>TURKEY</p><h2>Manufacturer</h2><p>Makina ve Kimya Endüstrisi Kurumu ( MKEK )</p><p>Type: 76 mm AP-T M339</p><p>Description: Standard US specifications.
