Type 1X were Anti-Submarine (ASW) frigates (when the numbers ran out in the 1960s, ASW frigates continued as the Type 2X series).

Type 3X were General-Purpose (GP) frigates (Chosen 2015)
Type 4X were Anti-Aircraft (AAW) frigates (this later evolved into the "Destroyer" Type series).
Type 6X were Aircraft-Direction (ADW) frigates.
Type 8X were multi-role ships.



1950년대에 처음 만들어진 기준인데

1X 랑 2X는 대잠호위함

3X는 다목적 호위함(2015년부터)

4X는 대공호위함(나중에 구축함으로 바뀜)

6X는 ADW 호위함

8X는 다목적함들. (함대랑 속도를 맞출수 있으면 구축함이고 아니면 슬루프)

이럼
