Northrop Grumman Bushmaster Chain Guns director Jennifer Zonneveld said: “We are committed to ensuring our US warfighter remains ahead of emerging threats, and the XM813 will deliver overmatch and greater standoff range for Stryker crews.

Initially, the chain guns were deployed with the 2nd Cavalry Regiment’s Stryker fleet based in Germany to meet urgent operational requirements.

The current contract will deliver XM813 to an additional US Army Brigade Combat Team.

Northrop Grumman will utilise its facility in Mesa, Arizona, US, to produce these chain guns.

In October, the US Army tested the new capabilities of the Stryker Anti-Tank Guided Missile (ATGM) vehicle.

The upgrades included enabling the crew to transfer images, reports and cue targets between vehicle platforms and within the platoon to boost operational effectiveness.
