A note on Colony Class Frigates
The design Colony class frigate was based on that of the Tacoma class frigates used by the United States Navy (some sources state that these vessels were identical). That design was itself an adaptation of the Royal Navy River class frigate, with modifications made mainly to use materials and parts more readily available in the United States. For example, American 3-inch guns were used as the main surface armament in the Tacoma and Colony class frigates instead of the British 4-inch guns of the River class.
They were mass-produced to mercantile standards to enable their speedy construction in shipyards that did not normally build warships. Post-war, all were returned to the U.S. by the end of 1946 and most scrapped during 1947, as they were considered obsolescent even before the end of the war.
