During the 1970s, the Navy Diving School (Flottans dykarskola) was added to the flotilla, which later formed the Diving Division (Dykdivisionen), which included submarine rescue ships.
Under 1970-talet tillkom Flottans dykarskola till flottiljen, vilken senare bildade Dykdivisionen, där bland annat ubåtsräddningsfartyg ingick i.
