A similar risk existed even with PF but it was limited to the implementation of Patrol Frigates (Rivers and Tacomas) as their own typology. Even if this happens, confusing foreign PF with Kaiboukan is still less troublesome, as they are at least much more similar than DEs. This is just flat wrong. DE perfectly describes the role of the Kaikouban : Escrot ships capable of 20 knots and open ocean endurance to protect convoys of unarmed ships,  when using the USN classification system. Post war the name even changed from DE(Destroyer Escort) to DE(Ocean Escort).

There was only a single class of ships classified as PF, the Tacoma-class. USN PF where meant to be longer ranged version of DE, but where immediatley discontinued after the Tacoma-class because they where decidedly inferior to the shorter ranged and often smaller DE-classified ships. The USN also completely abandoned the Firgate classification until the early 1970s when they started building guided missile frigates.
