| Notes on class | This grouping includes all sloops capable of outrunning surfaced type VII and IX U-boats. Although production was limited by competing priorities for available turbine machinery, this design was favoured by experienced anti-submarine officers. The large number of U-boat kills credited to this class reflect the leadership of F J "Johnny" Walker who commanded the 36th Escort Group from Stork and later the 2nd Escort Group from Starling. |
