The 60 mm M73 HE mortar shell is a Serbian high-explosive round in the Yugoimport and Krušik 60 mm mortar-shell catalogs. Beyond catalog data for M57 mortar firing, open reporting and UN monitoring have tied M73 rounds to Ukrainian use, al-Shabaab mortar attacks in Somalia, and seized ammunition after the 2023 Banjska attack.

M57 Firing And Family Context

Yugoimport's M73 sheets tie the shell to the M57 light mortar rather than documenting independent conflict use for the shell itself. The two sheets also show contract-dependent configuration differences, including 286 mm and 291 mm listed fuzed lengths and 250 g or 220 g TNT fill entries.

Firing weapon

Ballistic data is published for the 60 mm Mortar M57 with 650 mm and 720 mm barrel configurations.

Source context: 60 mm, M73 - HE mortar shell - Yugoimport; 60 mm, M73 - Yugoimport.

Charge and packaging

The shell is listed with an ignition cartridge and increment charges, one complete shell per carton, and 12 cartons per wooden case or box.

Yugoimport states that final configuration is contract-defined.

Family labels

Krušik groups M73 with M73PX, M73P3, Mk10, and related smoke, illuminating, and UAV-drone mortar-shell listings.

The M73-D sheet identifies a separate drone-fuzed HE member, not the baseline mortar-fired M73 shell.

Its official sheets describe a high-angle fire-support weapon built around barrel, base plate, bipod, sight, tools, spares, and accessories; post-Yugoslav records also show Serbian surplus stocks and Balkan export activity. In the 2020 Nagorno-Karabakh Conflict, open-source loss documentation recorded M57 mortars captured from Armenian forces.
