A total of fifty-seven "E" Class Submarines entered service in the Royal Navy and Royal Australian Navy between 1913 and 1917. The Royal Navy considered these to be "patrol" (as opposed to coastal or fleet) submarines.[1]

Though they were produced in considerable numbers, the "E" boats were so successful that their numbers were deemed insufficient. In light of this view, the "L" class boats would be designed and prduced as enlarged "E"s.[2]

Performance

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.[3]

History

E 28 was cancelled before completion.

On 11 November, 1914, a conference of representatives of shipbuilding firms were asked to prioritise their capacity to build "E" class boats, and this resulted in an order for 38 boats from 12 firms, with an additional two being ordered from Denny before the month was out.

Radio

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.[4]

Torpedoes

E 1 - E 8:

  • four 18-in tubes (one forward, one stern, 2 broadside), eight torpedoes

E 19 - E 25 (as specified in 1913):[5]

E 9 - E 56 (as delivered):[6]

  • two 18-in tubes forward, undepressed, Elswick high impulse or Service
  • two 18-in tubes broadside, undepressed, Service
  • one 18-in tube aft, B lip end in E 19 and later

Minelayers:

  • three 18-in tubes (two forward, one stern)
  • twenty mines

Guns

Though in 1912 it had been decided that all "oversea" submarines should carry a 12-pdr, this class was built without a gun.[7]
