In 1917, K6 did not surface during a trial in North Dockyard, Devonport. K6 was involved in a serious exercise accident nicknamed the "Battle of May Island". She was responsible for ramming K4 and slicing her in half. She was sold on 13 July 1926 to John Cashmore Ltd for scrapping at Newport.

Design

K6 displaced 1,800 long tons (1,800 t) when at the surface and 2,600 long tons (2,600 t) while submerged.^[1] It had a total length of 338 feet (103 m), a beam of 26 feet 6 inches (8.08 m), and a draught of 20 ft 11 in (6.38 m).^[2] The submarine was powered by two oil-fired Yarrow Shipbuilders boilers supplying one geared Brown-Curtis or Parsons steam turbine; this developed 10,500 ship horsepower (7,800 kW) to drive two 7 ft 6 in (2.29 m) screws. Submerged power came from four electric motors each producing 350 to 360 horsepower (260 to 270 kW).^[2] It was also had an 800 hp (600 kW) diesel engine to be used when steam was being raised, or instead of raising steam.^[3]

The submarine had a maximum surface speed of 24 kn (44 km/h) and a submerged speed of 9 to 9.5 kn (16.7 to 17.6 km/h).^[2][4] It could operate at depths of 150 ft (46 m) at 2 kn (3.7 km/h) for 80 nmi (150 km).^[1] K6 was armed with ten 18-inch (460 mm) torpedo tubes, two 4-inch (100 mm) deck guns, and a 3-inch (76 mm) anti-aircraft gun.^[2] Its torpedo tubes were fitted to the bows, the midship section, and two were mounted on the deck.^[1] Its complement was 59 crew members.^[4]
