HMS K16 was a K class submarine built by William Beardmore and Company, Dalmuir. She was laid down in June 1916 and commissioned on 13 April 1918. The only incident that occurred with K16 was a sudden dive in Gare Loch after her hydroplanes failed. She surfaced successfully. K16 paid off on 12 December 1920. She was sold on 22 August 1924 and was resold in September 1924 in Charlestown.

Design

K16 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 shaft 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 a maximum depth of 150 ft and travel submerged at 2 kn for 80 nmi. K16 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 in a rotating mounting on the deck. Its complement was fifty-nine crew members.
