"G" Class Submarine (1915)
Fourteen "G" Class Submarines were completed for the Royal Navy early in the war. G 15, to be built by White, was cancelled in April, 1915. The Royal Navy considered these to be "patrol" (as opposed to coastal or fleet) submarines.
The design inaugurated the use of 21-in submarine-borne torpedoes in service.

The Grand Fleet Battle Orders specified that the top speed on the surface was 14 knots, but that a more realistic "sea-going speed" was 12 knots.
By war's end, all boats of "E" class and later were given 3 kilowatt Poulsen wireless sets, affording ranges of 200 miles submarine-to-submarine, and 300-400 miles between shore stations and submarines. Reception of shore stations of 400 miles was common, and high power shore stations could be received over 500-600 miles.
