U.S. M198 155mm Howitzer


Introduced in 1978, the M198 replaced the World War II vintage M1/M114A2 155mm Howitzer for the U.S. Army and the Marine Corps. The howitzer has a split trail carriage and the wheels could be rotated up to allow the howitzer to rest on its firing platform. The top carriage with the howitzer tube could be rotated 360 degrees so that the tube rests above the trails for towing. The howitzer could also be towed with the tube facing to the rear. The M198 had a maximum range of 22,000 meters with conventional rounds and 30,000 meters with Rocket-Assisted Projectiles (RAP). Approximately 1,800 M198 Howitzers were produced by 1988, with approximately 800 of those going to allied countries. The howitzer saw extensive use during Operation Desert Storm with Army and Marine artillery units. It was replaced by the M777 Lightweight Howitzer beginning in 2005. This M198, named Thor, was used by Bravo Battery, 1st Battalion, 78th Field Artillery at Fort Sill.
