[edit] Summary

With the realisation that war was approaching, 13 Grimsby class sloops were laid down in the mid to late 1930s. Of these eight were built in the United Kingdom for the Royal Navy, four in Australia for the Royal Australian Navy and one for India. Armament varied considerably between ships with the four Australian ships being similar to HMS Depthford but armed with an additional 4 in gun.

Losses during World War II were HMS Grimsby, HMAS Yarra and HMAS Parramatta.

Post-war some of the survivors of this class served into the 1960s.
