The twin engines gave only three more knots of speed but extended the range of the ship to nearly double that of a corvette at  at 12 knots. Among other lessons applied to the design was an armament package better designed to combat U-boats including a twin 4-inch mount forward and 12-pounder aft.
The twin engines provided minimal increase in speed but significantly extended the ship's range to nearly double that of a corvette at 12 knots. The design also included an armament package optimized for U-boat defense, featuring a forward twin 4-inch mount and a 12-pounder aft.
