155 mm artillery round in the 2014 Russia-Ukraine War

155 mm artillery rounds became a central ammunition category for Ukrainian artillery after the 2022 full-scale invasion, with NATO describing the caliber as commonly used by Ukrainian forces and official U.S. and EU sources documenting large-scale supply.

Documented Use

Direct proof of use

155 mm artillery rounds are directly documented in Ukrainian service during the 2014 Russia-Ukraine War through official alliance and government sources. NATO Secretary General Jens Stoltenberg described 155 mm ammunition in July 2023 as the most commonly used battle-decisive ammunition in the war in Ukraine, or by Ukrainian forces.

U.S. and European Union records document the transfer and procurement pipeline behind that battlefield use. The U.S. Department of Defense listed 126 155 mm howitzers and 260,000 155 mm artillery rounds committed to Ukraine by June 24, 2022, while the Council of the European Union approved financing for jointly procured 155-mm-calibre artillery rounds for the Ukrainian Armed Forces in May 2023.

Supply and fielding timeline

Public U.S. security-assistance records show the scale of the early 155 mm transition after Russia's February 2022 full-scale invasion. By June 24, 2022, U.S. commitments included 155 mm howitzers and hundreds of thousands of 155 mm artillery rounds; later Department of Defense fact sheets listed more than 3,000,000 155 mm artillery rounds, more than 7,000 precision-guided 155 mm artillery rounds, and more than 70,000 155 mm RAAM rounds among U.S. assistance to Ukraine.

European support followed the same ammunition priority. On May 5, 2023, the Council of the European Union adopted a EUR 1 billion European Peace Facility measure to finance provision of 155-mm-calibre artillery rounds to the Ukrainian Armed Forces, following a March 2023 EU plan aimed at speeding delivery and joint procurement of artillery ammunition for Ukraine.

Battlefield role

In Ukrainian service, 155 mm rounds supplied NATO-standard and NATO-compatible howitzers used for defensive and offensive fire support. U.S. Army acquisition reporting described U.S. contributions of more than two million rounds of artillery as supporting Ukrainian defenses and counteroffensive operations, and a later Joint Munitions Command article said its Ukraine support was mainly 155 mm artillery rounds that helped bolster Ukrainian defensive and offensive capabilities.

RUSI field research from the third year of the full-scale war described 155 mm shells as available in greater volume than earlier in the conflict, while also noting practical constraints: Ukrainian artillery officers reported shortages of working guns, spare parts, and compatible charge bags, and units mainly had access to high-explosive shells with only occasional specialized ammunition. The record therefore supports a broad fire-support and foreign-aid role, not a claim that every 155 mm projectile type was widely available.
