M109A3

The M109A3 is a self-propelled 155mm howitzer, part of the widely used M109 family of armored artillery systems. It represents an upgrade of earlier M109 variants, featuring improved range, reliability, and often incorporating the M185 cannon.

Developed in the mid-1970s as a depot-level upgrade to existing M109A1 units, the M109A3 entered service to standardize reliability, availability, and maintainability improvements across the U.S. Army's self-propelled artillery fleet. The system saw significant combat deployment during the 1991 Gulf War with American forces and was widely exported to NATO allies and global partners. Notably, former Norwegian M109A3GN variants were donated to Ukraine in 2022, where they have seen active use in the conflict with Russia. While the United States has since replaced the A3 variant with more advanced models like the M109A6 Paladin, it remains in active service with several international militaries.
