Ship project history: These ships were larger, better armed and faster in comparison with Grimsby class sloops. They were designed under 1933-1935 Programmes. Under the original design Bittern class sloops should carry 4 120mm guns, having caught up British destroyers, however any of them has not received these guns. Enchantress was completed as an admiral's yacht with increased aft superstructure and only two main guns (the third was installed in May, 1936 but soon removed). She was commissioned as a rescue ship and first time did not carry arms. Bittern instead of regular 120mm guns received 6 102mm guns in twin mounts. Occurrence of Denny-Brown stabilizers became the important innovation. This ship has appeared very successful and served as a prototype for several series of AA sloops, designed throughout war.

Modernizations: Bittern was commissioned as survey ship without armament and armed in 1939.
