Usage

Ammunition in 30 mm is typically not used against personnel but rather as an anti-materiel or armor-piercing round. Rounds of this size can be effective against lightly armored vehicles as well as fortified bunkers. It is also a popular caliber for shipboard close-in weapons systems (CIWS), such as the Russian AK-630 and Dutch Goalkeeper CIWS.

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, Ka-50 attack helicopter, and the BMP-2, BMP-3, and BTR-90 infantry fighting vehicles. The most modern anti-aircraft gun systems in use by Russia are chambered in 30 mm.

The U.S. military uses 30 mm weapons in their A-10 Thunderbolt II ground-attack aircraft, AC-130 gunship (AC-130J Ghostrider variant), and AH-64 Apache attack helicopter. It was going to be used in the Expeditionary Fighting Vehicle, until the project was canceled. The United States Navy uses 30 mm weapons on the San Antonio-class amphibious transport dock and on Freedom and Independence-class littoral combat ships as part of the surface warfare (SuW) package.[1][2] In 2012, the Navy decided to replace the Mk 110 57 mm cannons on Zumwalt-class destroyers with the Mk 46 GWS.[3] The United States Coast Guard plans to install 30 mm weapons on the Polar Security Cutter[4]

Types of ammunition

30 mm calibre weapons are used in a variety of roles. As a result, ammunition in 30 mm comes in several varieties: armor-piercing (AP), high-explosive (HE), airburst, and target practice (TP) rounds. Both AP and HE cartridges commonly possess incendiary or tracer elements, which may be noted in its designation; API and HE-T are Armor-Piercing Incendiary and High-Explosive Tracer respectively.[5]
