NotesIn WW1 the US army decided to replace their heavy 6in M1906 guns with the more modern French GPFs. After the war the army built their own under licence resulting in the M1918M1 gun. In 1940 the US army had 973 of these heavy guns which made it the most numerous gun in service. In 1937 a new high speed carriage had been developed for mechanized towing and the army decided to up-grade the M1918. This was a slow progress and only 598 were modernised between 1941 and 1942. The M1918A1 saw action in the early phases of WW2 but when the more modern 155mm M1A1 Gun came into use in 1942 it was gradually used as a coastal Gun and was deployed in this role in the Pacific theatre until 1945.
