HMS K7 was a K class submarine built by HM Dockyard, Devonport. She was laid down on 8 November 1915 and commissioned in July 1917.

K7 was the only one of the disastrous K class to engage with an enemy; on 16 June 1917 she fired a salvo of torpedoes at the U-boat U-95 and scored a direct hit. However, the torpedo failed to explode with what has been described as typical "K" luck; K-7 escaped retaliation by steaming away at speed.[1]

K7 was involved in an accident with the 4th Light Cruiser Squadron. She was also involved in the catastrophic series of accidents during a night exercise that came to be known sarcastically as the Battle of May Island; K7 was damaged by running over the sinking Шаблон:HMS. K7 was sold on 9 September 1921 at Sunderland.

Design

K7 displaced Шаблон:Convert when at the surface and Шаблон:Convert while submerged.[2] It had a total length of Шаблон:Convert, a beam of Шаблон:Convert, and a draught of Шаблон:Convert.[3] The submarine was powered by two oil-fired Yarrow Shipbuilders boilers supplying one geared Brown-Curtis or Parsons steam turbine that developed 10,500 ship horsepower (7,800 kW) to drive two Шаблон:Convert screws. Submerged power came from four electric motors each producing Шаблон:Convert.[3] It also had an Шаблон:Convert diesel engine to be used when steam was being raised, or instead of raising steam.[4]

The submarine had a maximum surface speed of Шаблон:Convert and a submerged speed of Шаблон:Convert.[3][5] It could operate at depths of Шаблон:Convert at Шаблон:Convert for Шаблон:Convert.[2] K7 was armed with ten Шаблон:Convert torpedo tubes, two Шаблон:Convert deck guns, and a Шаблон:Convert anti-aircraft gun.[3] Its torpedo tubes were fitted to the bows, the midship section, and two were mounted on the deck.[2] Its complement was fifty-nine crew members.[5]
