US Cartridge, 105mm Smoke WP-T, M416




This cartridge is intended for screening and spotting fire from 105mm gun cannons. There is some limited incendiary effect.

The thin walled projectile is cylindrical in shape with a relatively short ogive and is fitted with two gilding metal rotating bands. The projectile is loaded with white phosphorous (WP), and has a base-detonating fuze and an extended tracer. The shell contains a centrally oriented burster of Composition B. To increase in flight stability at temperatures above + 110°F the burster casing is machined with a six-bladed impeller which extends into the WP filler. The cartridge case contains bagged propellant and is equipped with an electric primer.
