203mm M110/M110A2 SP

The M110 is a self-propelled 203mm (8-inch) howitzer developed by the United States for long-range fire support. The M110A2 is an upgraded variant featuring a longer barrel and improved ammunition capabilities, enhancing its range and effectiveness.

Developed in the late 1950s to replace the heavy M55, the M110 entered service with the U.S. Army in 1963, utilizing a new lightweight chassis designed for air transportability. The system saw extensive combat during the Vietnam War and was later deployed during Operation Desert Storm, while also serving as a key tactical nuclear delivery platform for NATO during the Cold War. Although retired from U.S. active duty in the 1990s in favor of rocket artillery, the M110A2 variant continues to be operated by several allied nations worldwide.
