ATK produces a full spectrum of 20mm x 102mm ammunition for air, ground and
sea platforms. These cartridges include armor-piercing, anti-materiel and
personnel, and cost-effective training ammunition. These rounds provide the
outstanding accuracy, lethality and penetration necessary to defeat the threats
on the battlefield today and tomorrow.
Our 20 mm ammunition is used in various platforms and applications. The
rounds are used in fixed-wing aircraft for combat applications to support
air-to-air and air-to-ground missions. They also are used in rotary-wing
applications for air-to-ground missions. The 20mm ammunition also is the last
line of defense against today’s modern littoral and anti- ship threats. It also
is used in a ground-based defense system to counter rocket, artillery and mortar
attacks, and the danger of speeding cars loaded with explosives.
The rounds can be fired from the M39A2, M61A1, M197 and M621
