120 mm M74 mortar

Also known as
  • M74
  • M-74
  • 120 mm M74

The 120 mm M74 is a Yugoslav-origin towed mortar developed in the mid-1970s as part of the M74/M75 light-mortar generation. Current Serbian, Bosnian, Polish, and SIPRI records keep the system in the export-industrial and wartime-transfer record, while open-source conflict documentation places captured examples in Nagorno-Karabakh and a CIG-identified M74 in RSF-linked fighting at El Fasher.

Mobility And Fire Profile

The M74 is presented in official product literature as a light 120 mm close-support mortar for high-angle fire, smoke, illumination, and infantry support in broken terrain.

Fire mission

Yugoimport describes the mortar as a close infantry-support weapon for personnel, firing points, light fortifications, smoke-screen work, and night illumination.

Firing arc

Product sheets give 45 to 85 degrees of elevation, 3 degrees left/right traverse without shifting the bipod, and all-around traverse after bipod displacement.

M62P3 baseline

Both PPT Namenska and Yugoimport tie the public 6,440 m maximum range figure to the 120 mm M62P3 mortar bomb or mine.

Variants

VTI history treats the M74 and M75 as related second-generation 120 mm light mortars developed from the mid-1970s Yugoslav fire-support program.

VTI places the M74 and M75 together in the same mid-1970s light-mortar generation that followed the M52 and preceded the longer-range M95.

Ammunition Fired

PPT Namenska and Yugoimport list the M74 mortar with the 120 mm M62P3 mine or ammunition as its maximum-range round, and ITC catalogs the same designation as a 120 mm HE mortar bomb.

  4. M74 mortars recorded in Ukraine transfer reporting

    Polish export reporting and SIPRI transfer-register data both record 2023 deliveries of 22 M74 / M-74 120 mm mortars to Ukraine, supporting a wartime transfer context rather than confirmed battlefield firing.

120 mm M75 mortar, 120 mm towed smoothbore mortar, ArtilleryArtillery120 mm M75 mortar120 mm towed smoothbore mortarThe 120 mm M75 mortar is a Yugoslav-designed towed smoothbore mortar associated with the M74/M75 light-mortar family and post-Yugoslav export literature. Yugoimport describes it as infantry close-support artillery for high-angle fire, smoke, illumination, and difficult terrain, while Serbian sources and later defense reporting show the legacy weapon being paired with modern fire-control equipment. Direct records place M75 mortars in JNA fire support around Dubrovnik in 1991 and in Armenian/Artsakh losses during the 2020 Nagorno-Karabakh war.

Direct open-source documentation links the family to Afghan government losses in 2021, Syrian opposition use near Aleppo, Armenian and Artsakh losses in Nagorno-Karabakh, and Ukrainian wartime receipt of BNT-marked M69A mortars.

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.

Rosoboronexport describes the export system as a modular radar for battalion-to-brigade fire support: detecting 81-120 mm mortar positions, tracking shell bursts for artillery correction, and observing moving ground targets out to 20 km. Specialist radar references describe a 135 kg J-band set, while open-source conflict reporting documents Russian-linked use in Syria and Ukraine plus Armenian/Artsakh wartime fielding problems in the 2020 Nagorno-Karabakh conflict.
