203mm M115 TOWED

The M115 8-inch Howitzer is a heavy towed artillery piece developed by the United States, firing 203mm (8-inch) shells. It was widely used by the US Army and its allies from World War II through the Cold War, providing heavy fire support.

Developed in the late 1930s to replace aging World War I-era designs, this heavy howitzer was standardized as the M1 in 1940 and shared a common carriage with the 155mm "Long Tom" gun to simplify logistics. It entered active service during World War II, where it gained a reputation for devastating accuracy, and was subsequently deployed extensively during both the Korean and Vietnam Wars. While the United States military phased out the towed system in favor of self-propelled platforms like the M110 in the late 20th century, the M115 continued to serve in the reserve forces of several allied nations, including Taiwan and Turkey, well into the 21st century.
