The Royal Navy's eight "D" Class Submarines entered service between 1908 and 1911. The Royal Navy considered these to be "patrol" (as opposed to coastal or fleet) submarines.[1]

They were significantly larger than the preceding classes and, with twice the endurance offered the British their first plausible ocean-going submarines.

Performance

The Grand Fleet Battle Orders specified that the top speed on the surface was 13 knots, but that a more realistic "sea-going speed" was 11 knots.[2]

Torpedoes

  • three 18-in tubes (two forward and one stern), six torpedoes

Guns

in D 4 only:

  • one 12-pdr

D 4 was the first submarine to be armed with a gun.[3]
