Design
Like all British K-class submarines, K9 had a displacement of 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 and 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. It also contained four electric motors each producing 350 to 360 horsepower (260 to 270 kW).[2] It was also fitted with a diesel engine providing 800 hp (600 kW) 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; 28 mph) 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] K9 was fitted with a 3 inches (76 mm) anti-aircraft gun, ten 18-inch (460 mm) torpedo tubes, and two 4-inch (100 mm) deck guns.[2] Its torpedo tubes were fitted to the bows, the midship section, and two were mounted on the deck.[1] Its complement was fifty-nine crew members.[4]
