Flower-class sloops as task-group security ships

Its low speed and limited surface combat power make the ship unsuitable as an all-threat picket. A picket must detect, survive, or escape a broad range of attacks, whereas a Flower-class sloop was built to handle particular dangers well. Within a convoy or task group it supplies focused security against submarines and mines rather than serving as the principal surface fighter. The same modest armament remains sufficient for piracy, fishery protection, warning shots, and other lower-threat presence missions.
