Mortar xplosive 60 mm

cults3d

This is the American 60mm M49A2 and M49A3, high-explosive (HE) fragmentation, fin stabilised mortars also produced as a copy in Turkey. The M49A2 uses a cast-steel body of teardrop shape, with four gas check grooves at the bourrelet and a screwed-in steel tail unit. The body of this shell may be constructed of forged steel, cupped-rolled, plate-welded longitudinally, or a machined casting. It is tear-dropped in shape, having a blunt nose and tapered tail. Near the nose end of the shell is a machined bourrelet which acts as a forward bearing surface and as a gas check. The nose is threaded to receive the fuze directly. The nose is threaded for an M525 or similar impact fuze. The primary cartridge is a shotgun type inserted into the centre of the tail unit and four secondary charges, in plastic containers, clip in between the fins. The M49A2 contains a main charge of 153 grams (5.4 oz) of flake TNT. The M49A3 contains 190 grams (6.7 oz) of Composition B.
