Project history

Initially classified as coastal sloops. As well as their direct predecessors of "Р" class intended, first of all, for the ASW service. The beautiful ships, but very poorly adapted  to the basic purpose. Their shallow draught was, more likely, a lack, than advantage as overall sonar performance directly depends on depth of its placement. Besides, the ships had no stock of displacement for serious strengthening of air defence weapons. Last circumstance would be not so important, it appear endurance of these ships sufficient for their usage somewhere outside of an inshore British waters. Alas, as a result of a small fuel stowage low endurance and seaworthiness have limited their usage in those places where the greatest threat from air first of all was expected.

Modernizations

1940, all: + 1 x 4 - 12.7/62, DC stowage was increased up to 60

1940, Shearwater: + 1 x 1 - 76/40 12pdr 12cwt QF Mk I/II/V

1941-1943, survived: + type 271 radar

1942, all survived: - 1 x 4 - 12.7/62; + 2 x 1 - 20/70 Oerlikon Mk II/IV

1/1946: 1 x 1 - 102/45 HA Mk III, 2 x 1 - 20/70 Mk III, 4 DCT, 2 DCR (60), type 271 radar, type 127 sonar

Naval service

Pintail was mined and sunk off Humber 10.6.1941.
