The M795 is a 155 mm high-fragmentation, steel (HF1)-body projectile, filled with 10.8 kilograms (23.8 lb) of TNT.It weighs approximately 47 kilograms (103 lb). The high-fragmentation steel body is encircled by a gilding metal rotating band, making it compatible with 3W through 8S (M3A1 through M203A1) zone propelling charges across all current 155 mm howitzers.
