Notes on class

The specifications as listed above are for the 'normal' D-class destroyers. HMS Duncan was fitted as flotilla leader and had some different specifications;
Displacement: 1400 BRT
Complement: 175 men.

Despite the fact that the Admiralty recognised that the 'standard' British destroyer design looks very week, compared to the larger U.S., French and even Japanese destroyers, they decided to retain the 4.7" gun as main armament.

The D-class destroyers were repeat C-class destroyers with only minor modifications.
