The 90 mm Smoke M313/M313C is a fixed round with the projectile crimped into the brass cartridge case. A single gilding metal drive band encircles the projectile just forward of the case/projectile junction. The 90 mm Smoke M313/M313C projectile consists of a hollow steel forging with a boat tailed base and a streamlined ogive. A PD or MTSQ fuze is fitted to the nose above an internal burster casing. This is a thin-walled steel tube containing an M24 burster 66 g of tetrytol and an M2 burster initiator. The
burster tube extends from the fuze adaptor to the rear of the projectile cavity, forming a seal for the White Phosphorus (WP) filling which weighs 894 g. As the fuze functions the burster charge is initiated via the M2 burster initiator. The projectile casing ruptures to spread the WP contents. On contact with the air these begin to burn, creating dense white screening smoke plus flaming particles. The cartridge case used is the brass M19 or M19B1. Press fitted into the base is an M28A2, M28B2 or M49 percussion primer although the DM 141 may also be encountered. The M313 contains 3.316 kg of M6 or M15 propellant. The M313C contains 2.418 kg of M1 propellant. The 90 mm Smoke, WP, M313 and M313C are used for target marking and to create screening smoke. They also have a limited incendiary effect. The main difference between the two rounds is that the M313C uses a different propellant load which reduces muzzle velocity and barrel wear. Applications include m36 Cannon on M47 series MBTs; M41 Cannon on M48 series MBTs up to (and including) M48A3.
