The boats were seemingly cursed.
They were required to "steam at 23 knots, to dive in five minutes, to dive for six hours, and to be seaworthy on the high seas." An oddly rosy post-war appraisal indicated that they surpassed their requirements, achieving dives in 24 minutes and 15 seconds (K 8 managed 3 minutes, 25 seconds on one occasion). K 12 maintained 24.2 knots over 72 miles. Ten hours of submerged endurance was manageable in calm weather, and two of the boats overtook the Grand Fleet in a gale in September 1918.
Original design Boats:
- ten 18-in tubes (four forward, four broadside, one twin revolving mount in superstructure) eighteen torpedoes
- six 21-in tubes forward, twelve torpedoes
- four 18-in broadside tubes, eight torpedoes
Original design Boats:
- two 4-in Q.F. guns
- one 3-in H.A. mount
- three 4-in Q.F. guns
