Medium- and Large-Caliber Ammunition

The company is a leading producer of medium- and large-caliber tactical and training ammunition for U.S. and Allied militaries. Looking to the future to provide ammunition capabilities that increase the capabilities of weapon systems to meet peer and near peer threats, Northrop Grumman is at the forefront of developing new, advanced ammunition types that include advanced armor penetration, airbursting, proximity fuzed and multipurpose warheads for systems ranging 20mm to 120mm.

Medium caliber ammunition developments are on a path which includes airbursting and the creation of a new, proximity fuzed warhead for 30mm x 113mm ammunition that will provide greater capability for the Apache attack helicopter to engage air to ground and air to air targets. Once complete, the technology will be scaled to multiple medium caliber types to provide air, land and sea weapons systems with a precision, bursting warhead. The development of the proximity fuze also will lead to the creation of medium caliber guided ammunition that will provide the precision necessary to engage moving targets and defeat unmanned threats – both air and ground.
