30 mm/1.1811 inch ammunition refers to one of several autocannon rounds: the 30 × 173 mm, 30 × 113 mm or 30 × 165 mm; the first two of which are used by the armed forces of NATO, the latter by former Warsaw Pact nations; these rounds are used by the armies of export customer nations as well.

Like the smaller 25 mm round, the 30 mm is not typically an anti-personnel weapon round. Instead, the 30 mm round is generally either an anti-materiel or armor-piercing round. Rounds of this size can be effective against armored vehicles as well as fortified bunkers.

The U.S. military uses 30 mm weapons in their A-10 Thunderbolt II and AH-64 Apache helicopter. It will be used in the AC-130 Gunship and the Expeditionary Fighting Vehicle. The Armed Forces of the Russian Federation use their 30 mm weapons in a variety of vehicles, including the Su-25 attack aircraft, Mi-24 helicopter, Mi-28 attack helicopter, and the BMP-2 infantry fighting vehicle.

Types of 30 mm ammunition

30 mm ammunition generally comes in three varieties: armor piercing (AP), high explosive (HE), and training rounds. Armor piercing and high explosive cartridges usually also possess incendiary characteristics. Anti-material and armor piercing rounds use depleted uranium to pierce armor. When the depleted uranium hits the metal at high speed, the kinetic energy ignites the uranium particles that contact oxygen. After hitting, the depleted uranium leaves low levels of radiation on the target. To avoid this, tungsten may be used instead, as it is not a radioactive material, but its price is far greater than depleted uranium.
