L-2 underway, perhaps on her trials.[1]

The Royal Navy's "L" Class Submarines were completed between November, 1917 and some well after the war.[2]

The boats were designed and produced as enlarged versions of the successful "E" class boats.[3]

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

L 1 Group:

  • six 18-in tubes (4 forward, 2 broadside), ten torpedoes

L 9 Group:

  • four 21-in bow, eight torpedoes
  • two 18-in broadside, two torpedoes

L 9 Group Minelayers:

  • four 21-in bow
  • 16 mines (only 14 in L 25)

L 50 Group:

  • six 21-in forward, 12 torpedoes

Guns

Though the plan incorporated a 3-in 20 cwt gun on a disappearing mounting,[5] but as built the armament seemed to vary.[6]

Initially, L 1:

  • one 3-in H.A. gun on disappearing mounting

Initially, L 2 to L 8:

  • unknown (varied)

Eventually, all L 1 Group
