Northrop Grumman Corporation received a contract from the U.S. Army’s Project Manager for Maneuver Ammunition Systems (PM-MAS) to develop the next generation airburst cartridge for the 30mm XM813 Bushmaster® Chain Gun®. The gun and ammunition function as a system and will provide greater capability for the Army’s up-gunned Stryker Brigade Combat Team fleets.

The 30 mm x 173 mm airburst cartridge will feature a contact set fuze design with three operational fuze modes: Programmable Airburst, Point Detonation and Point Detonation with Delay. The initial contract will fund the completion of the engineering and manufacturing development (EMD) phase and final qualification by the Army.

Northrop Grumman will also begin deliveries this year of the first airburst type cartridge to support the U.S. Army’s Germany-based, 2nd Cavalry Regiment’s Stryker Infantry Carrier Vehicle (ICV) fleet that were recently ‘up-gunned’ with the company’s 30mm Bushmaster® Chain Gun®. The new airburst cartridge in development also will support additional U.S. Army platforms to include, but not limited to, the future Stryker Brigade Combat Teams.

The newly fielded gun system nearly doubles the range of the platform’s current .50-caliber machine gun. The addition of an airburst cartridge provides a complete family of ammunition that arms the crew to meet the challenges posed by peer and near-peer adversarial threat systems.
