HC Deb 03 March 1910 vol 14 c986
Mr. BURGOYNE

asked the First Lord of the Admiralty whether he can state the designed speed of the destroyer "Swift," her maximum speed on trial, and the period over which this maximum speed was maintained?

Mr. McKENNA

The designed speed is 36 knots for six hours. The greatest speed of which records were taken was 35.239 knots. This speed was the mean of six runs on the measured mile, taken during the fourth hour of the trial.
