The following submarine chasers were 173/174 feet long and used the PC designation. The large missing sections of these numbers for the most part come from the sharing of the same number sequence with the 110-foot submarine chasers that used the SC designation and the 134-foot patrol craft sweepers that used the PCS designation. This number sequence would end in 1964, and then restart with '1' for the Cyclone-class costal patrol craft.

Patrol frigate (PF)

s were designed and built to naval construction standards, and as such could only be built at yards experienced with naval standards. The United States Maritime Commission created its S2-S2-AQ1 design - which was based on the British-designed River class - for much the same role but using civilian construction standards. These ships would be classed by the Navy as the Tacoma class frigates. Twenty-one would be renamed as Colony-class frigates after transfers to the Royal Navy. Others would be transferred in 1945 to the Soviet Union under Project Hula.
