The Ultra-light weight Field Howitzer, designated M777A1 in the USA was selected in 1997 by a joint US Army/Marine Corps initiative to replace the existing inventory of M198 155mm towed howitzers. The constructionof the M777A1 makes extensive use of titanium and titanium castings, enabling a weight reduction of 3,175kg compared to the M198 howitzer which it replaces in the US Army and USMC inventory.
