HMS K14 was a K class submarine built by Fairfields in Govan, Scotland. She was laid down in November 1915, and commissioned on 22 May 1917. K14 was part of the Battle of May Island exercise on 31 January 1918, in which her steering jammed while avoiding a collision. She was rammed by HMS K22 behind the forward torpedo compartment, but did not sink, and was repaired. Two men were lost. K14 was sold on 16 February 1926 at Granton.

Design

K14 displaced 1800 LT when at the surface and 2600 LT while submerged. It had a total length of 338 ft, a beam of 26 ft, and a draught of 20 ft. The submarine was powered by two oil-fired Yarrow Shipbuilders boilers each supplying one geared Brown-Curtis or Parsons steam turbine; this developed 10,500 ship horsepower (7,800 kW) to drive two 7 ft screws. Submerged power came from four electric motors each producing 350 to 360 hp. It was also had an 800 hp diesel engine to be used when steam was being raised, or instead of raising steam. The submarine had a maximum surface speed of 24 kn and a submerged speed of 9 to 9.5 kn. It could operate at depths of 150 ft at 2 kn for 80 nmi. K14 was armed with ten 18 in torpedo tubes, two 4 in deck guns, and a 3 in anti-aircraft gun. The torpedo tubes were mounted in the bows, the midship section firing to the beam, and two were on a rotating mounting on the deck. Its complement was fifty-nine crew members.
