GENERAL SPECIFICATIONS (HOW SMOKE, WP - M110A2) 155mm smoke is used to provide concealing and spotting. It has the same general appearance as the 155mm High-Explosive (HE) M107 and has the same design features. The shell contains white phosphorus and is normally fitted with a nose-mounted Point-Detonating (PD) fuze. On impact, the fuze ignites the internal supplementary charge, which then ruptures the shell casing to release WP filling. As it contacts the air, the WP ignites to produce thick clouds of white smoke.
