M107 155 mm high-explosive projectile

Also known as
  • M107 HE
  • 155mm M107 HE
  • M107 high-explosive projectile
  • M107 155mm HE projectile
  • D544 deep-cavity M107
  • D571 normal-cavity M107

The M107 is a conventional 155 mm high-explosive projectile with a forged-steel body, TNT or Composition B fill, and deep- or normal-cavity variants for different fuze fits. U.S. Army ammunition records list it as an operations-and-sustainment item, Modern War Institute reporting places the M107 family in Ukraine's 155 mm ammunition mix, and U.S. emergency-sale notices document M107 deliveries to Israel during the 2023 Israel-Hamas War.

Role in Conflicts

2014 Russia-Ukraine War
Fire Support

Documented in Ukrainian 155 mm artillery service: a Modern War Institute article says Ukrainian forces operate many NATO and non-NATO 155 mm howitzers and identifies the U.S. M107 high-explosive family as a core shell family in Ukraine's ammunition mix.

Side
Israel

Supplied to Israel during the 2023 Israel-Hamas War: the Federal Register notice for the emergency sale says Israel requested 4,792 M107 155 mm HE projectiles, that the M107 and M795 projectile quantities had subsequently been delivered, and that the urgent 155 mm requirement was tied to Israel's war with Hamas and near-term operations in Gaza.

Variants

U.S. Army ammunition records distinguish M107 fuze-cavity configurations, while the later M795 is an adjacent 155 mm HE projectile selected to replace the standard M107 over time.

Fuze, Charge, and Range

The Army portfolio treats the M107 as a general-purpose 155 mm HE projectile with distinct fuze-cavity variants.

ItemDocumented detail
D544 deep cavityPermits the M782 Multi-Option Fuze; when other fuzes are used, a supplementary pressed-TNT charge keeps initiation continuous.
D571 normal cavityUses all fuzes except deep intrusion proximity fuzes.
EmploymentUsed for blast effect, fragmentation, and mining in support of ground troops and armored columns.
Range18.1 kilometers in the 2017 Army portfolio listing.
Ukraine interoperabilityModern War Institute describes M107-family HE rounds as central to Ukraine's 155 mm ammunition mix but cautions that the older family is limited with some modern high-zone charges.
Successor contextGlobalSecurity summarizes the M795 as the Army-selected eventual replacement for the standard M107, with greater range and lethality.

General Dynamics also describes MR103 as a training round ballistically matched to the M107, which keeps the projectile relevant as a reference shell for artillery training.

  4. Ukraine interoperability article highlights M107 limits

    Modern War Institute described the U.S. M107 HE family as a central part of Ukraine's 155 mm artillery ammunition while warning that older M107-family rounds have restrictions with modern high-zone charges.

Open munition references describe a nose-fuzed, boat-tailed steel shell with TNT or Composition B filling, while Ukrainian and defense-reporting sources document M106 projectiles being adapted to Ukrainian 2S7 Pion guns during the 2014 Russia-Ukraine War as Soviet-pattern 203 mm stocks became scarce.
