The M107 was an American self-propelled gun from the Cold War period. The first prototypes of the car were made in 1961, and serial production lasted in the years 1961-1972, ending with the production of about 1,200 copies of this vehicle. The M107 was powered by an engine General Motors 8V71T with a power of 450 hp. It was armed with a single M113 or M113A1 gun with a caliber of 175 mm. In the 1950s, one of the standard self-propelled guns used by the US Army was the M55 with a 203 mm gun. It was a successful weapon, but relatively inaccessible and unable to be transported by air. Trying to change this state of affairs, while maintaining a similar caliber of the main armament, the US Army expressed interest in the new self-propelled gun. The company's proposal was positively considered Pacific Car and Foundry Company, which eventually undertook the production of the M107. For its production, the universal T249 tracked chassis and the M113 or M113A1 field gun were used. The M107 was characterized by high mobility, high maximum speed and considerable range of the main armament. The great disadvantage was the exposed cannon service station, which did not even protect it against shrapnel or small-caliber weapons. From 1963, the M107 was in the line and was used extensively during the Vietnam War (1964 / 1965-1975). They were withdrawn from the US Army at the end of the 1980s. The M107 self-propelled gun was also exported to Greece, Israel (where it fought in the Yom-Kippur War in 1973), West Germany, Italy and Great Britain
