ww2dbaseAlthough the initial designs for these new howitzers began to materialize as early as 1931, the Great Depression caused the United States Army to delay this project. The development was resumed in the late 1930s, and the 8 inch Howitzer M1 field guns entered service in 1939. Each gun required a crew of 14 men and had an ideal rate of fire of 30 rounds per hour. These weapons were later redesignated M115 8 inch Howitzer. After WW2, they remained in service with the US Army and saw action in Korea in the 1950s, Vietnam in the 1960s and 1970s, and Croatia in the 1990s. Forces friendly to the United States during the Cold War also operated a number of them, which included the Republic of China, Republic of Korea, Iran, Turkey, and Pakistan, among others.

Would I be correct in thinking that the 8-inch M241E1 as employed on the M110 self propelled Heavy Howitzer, which entered US Army service in 1962, and the longer barrelled 8 inch M203 howitzer, as fitted to the M110A1, are direct descendants from the World War II 8 inch M1 howitzer.
