Design

There were 21 ships in the Halcyon class, built in two groups; the first using reciprocating steam engines, with steam turbines in the latter. They were generally smaller versions of the Grimsby class

 escort sloops. Niger and Salamander of the reciprocating group used vertical triple expansion engines, instead of the vertical compound engines of their sisters. As a result of the increased installed power they had a half knot speed advantage, even though they used slightly shorter hulls. The turbine ships used the same shorter hulls as Niger and Salamander, but with lower installed power, speed dropped back to 16.5 knots (32 km/h).

Gleaner, Franklin, Jason and Scott were completed as unarmed survey vessels, Sharpshooter and Seagull being converted to follow suit. They were all re-armed and deployed in their original role on the outbreak of war. Seagull had the first all-welded hull built for the Royal Navy.

Service history
