M109 howitzer

M109 howitzer is a self-propelled, 155mm howitzer used by the United States Army and other countries, developed by Chrysler and first introduced in the early 1960s. The development of the M109 was influenced by the Korean War and the need for a mobile, reliable, and accurate artillery system, as seen in the Battle of Chosin Reservoir and the Battle of Inchon. The M109 has undergone several upgrades and modernizations over the years, with significant contributions from General Dynamics and Bae Systems, and has been used in various conflicts, including the Vietnam War and the Gulf War. The M109 has also been used by other countries, such as Israel and South Korea, in various military operations, including the Six-Day War and the Korean Demilitarized Zone.

● Development

The development of the M109 howitzer began in the late 1950s, with the United States Army seeking to replace the M44 howitzer and the M52 howitzer, which were used during the Korean War and the World War II. The development process involved several companies, including Chrysler, General Motors, and Ford Motor Company, with significant input from the Aberdeen Proving Ground and the United States Army Armor Center. The M109 was designed to be a self-propelled, 155mm howitzer, with a range of over 15 km and a rate of fire of up to 4 rounds per minute, as demonstrated during the Operation Desert Storm and the Operation Iraqi Freedom. The development of the M109 was also influenced by the NATO standardization efforts, which aimed to create a common artillery system for all member countries, including Germany, France, and the United Kingdom.

● Design

The M109 howitzer has a 155mm howitzer mounted on a tracked vehicle, with a Detroit Diesel engine and a Allison Transmission transmission, similar to the M60 Patton and the M1 Abrams.
