Also known as
  • 105 mm HE M1
  • Cartridge, 105 mm, High-Explosive, M1
  • CTG, ARTY, 105MM HE, M1 W/O FUZE

The Cartridge, 105 mm, High-Explosive, M1 is a semi-fixed 105 mm HE artillery cartridge built around an M14-family case, percussion primer, M67 propelling charge, and forged-steel HE projectile. MSM Group and JPEO ammunition data describe the round's personnel-and-materiel fragmentation role, fuze compatibility, and roughly 11-11.5 km range class, while current catalog sources tie the M1 designation to M101-family and M119-series 105 mm howitzers.

Firing Weapons

Sources connect the M1 HE cartridge most directly to M101-family howitzers; light-gun-family compatibility is narrower and applies to L119/M119 weapons that use NATO-standard 105 mm semi-fixed ammunition.

Round Breakdown

MSM Group and JPEO ammunition data describe the M1 as a complete 105 mm HE cartridge rather than only a projectile. The round combines a case, primer, M67 propelling charge, and forged-steel HE projectile; exact component marks vary by source and production line.

Projectile

Forged-steel HE projectile for fragmentation and blast effects against personnel and materiel targets.

Case and ignition

M14-family brass case with a percussion primer; JPEO identifies the U.S. cartridge case as M14B4 and primer as M28B2.

Propelling charge

M67 propelling charge, with an 11-11.5 km maximum-range class in current product and JPEO data.

Fuze compatibility

JPEO lists M557PD, M739PD, M732VT, M767 ETSQ, and M782 MOFA fuzes for the M1 cartridge.
