The 105 mm Smoke WP OFUM PH 105 F1 is a fixed round, with the projectile rigidly secured to the brass or steel cartridge case by a single crimping ring. This engages in a pronounced cannelure on the projectile just to the rear of the copper or gilding metal drive band. The projectile is steel and is filled with 1.77 kg of White Phosphorus (WP). A point detonating FUI 56 fuze is threaded into the nose fuze cavity; the PD M51 may also be used. When the fuze functions on impact it ignites a centrally located burster
tube filled with Hexolite 50:50. The resultant internal pressure fractures the steel body and exposes the WP contents to the atmosphere, producing clouds of grey/white smoke for approximately 40 seconds, forming a smoke screen 75 m wide. The round uses an Mle F2 brass or steel cartridge case (of the M148 or M150 type - length 617 mm) with a TPA electrical primer in the base. The charge is a nominal 2.4 kg of multiperforated LB-7 T-70 single-base propellant. This propellant load produces a muzzle velocity of 695 m/s. The 105 mm Smoke WP OFUM 105 F1 produces a muzzle velocity of 695 m/s. Maximum effective combat range is 925 m. The 105 mm Smoke WP OFUM PH 105 F1 contains White Phosphorus (WP) and is virtually identical, visually and ballistically, to the HE OE 105 F1 (see previous entry) so is often employed as a training round in its place. This round is no longer in production. Applications include CN105F1 series tank guns; 105 mm 105 G2 gun; 105 mm 105 G1 gun; all 105 mm L7, Rh 105 and M68 series tank guns and South African GT7 tank gun.
