The M777 howitzer is a towed artillery piece manufactured by BAE Systems' Global Combat Systems division. Prime contract management is based in Barrow-in-Furness in the UK as well as manufacture and assembly of the titanium structures and associated recoil components. Final integration and testing of the weapon is undertaken at BAE's facility in Hattiesburg, Mississippi.
It is in the process of replacing the M198 howitzer 155 mm towed howitzers in the United States Marine Corps and United States Army. The M777 is also being used by the Canadian Forces, and has been used in action in March 2008 in Afghanistan along with the associated GPS-guided Excalibur ammunition.
