Commissioning CO was Lt. M. Winser, RN and the 1st Lieut was Lt. Edward R. M. Lane, RN.

This Submarine was one of a Group of ten H Class submarines ordered in the Emergency War Programme of November 1914 and built (using American supplied components) at the Canadian Vickers Yard at Montreal. Of these Submarines H1 to H4 were commissioned in late May 1915 at Quebec City and then made their way to the Mediterranean escorted by the Armed Merchant Cruiser HMS Calgarian.

Submarine H3 was on patrol in the Adriatic off the Austrian Naval Base at Cattaro on 15th July 1916 when she struck a mine which exploded, seriously damaging H3, which then sank with the loss of all hands.
