The Mk44 Bushmaster II 30mm chain gun is the growth version of the M242 Bushmaster. It is capable of firing 30mm ammunition, including new programmable air burst munitions. It has a 60% logistics commonality with the original Bushmaster. The GAU-23/A is the airborne version of the cannon.
The AN/AWS-2 Rapid Airborne Mine Clearance System (RAMICS) fires a special 30mm supercavitating projectile from a Bushmaster II gun to neutralize surface and near-surface mines. The system uses a gated electro-optic Laser Imaging Detection and Ranging (LIDAR) sensor for target re-acquisition and a 30mm MK44 Bushmaster II gun for neutralization.
