1940 M2 155mm Long Tom Field Gun

The M1 and M2 155mm "Long Tom" field guns, standardized in 1938 and later redesignated as the M59, served as the primary heavy towed artillery pieces for the United States military during the mid-20th century. Designed to replace the aging French-derived artillery of World War I, the gun featured a newly designed split-trail carriage and an interrupted-screw breech mechanism, allowing it to accurately fire heavy 95- to 100-pound projectiles to a maximum range of 14.7 miles. Production spanned from 1940 to 1945 with 1,882 units manufactured, seeing extensive combat deployment across North Africa, Europe, and the Pacific during World War II, as well as later service in the Korean War.
