HMS E2 (originally ordered as HMS D10) was a British E class submarine built by Chatham Dockyard. E2 was laid down on 14 February 1911 and launched on 23 November 1912.

She was sold 7 March 1921 to B Zammit, Malta.

Design

The early British E-class submarines, from E1 to E8, had a displacement of 652 tonnes (719 short tons) at the surface and 795 tonnes (876 short tons) while submerged. They had a length overall of 180 feet (55 m) and a beam of 22 feet 8.5 inches (6.922 m), and were were powered by two 800 horsepower (600 kW) Vickers eight-cylinder two-stroke diesel engines and two 420 horsepower (310 kW) electric motors.[1][2] The class had a maximum surface speed of 16 knots (30 km/h; 18 mph) and a submerged speed of 10 knots (19 km/h; 12 mph), with a fuel capacity of 50 tonnes (55 short tons) of diesel affording a range of 3,225 miles (5,190 km; 2,802 nmi) when travelling at 10 knots (19 km/h; 12 mph), while submerged they had a range of 85 miles (137 km; 74 nmi) at 5 knots (9.3 km/h; 5.8 mph).[1]

The early 'Group 1' E class boats were armed with four 18 inches (460 mm) torpedo tubes, one in the bow, one either side amidships, and one in the stern; a total of eight torpedoes were carried. Group 1 boats were not fitted with a deck gun during construction, but those involved in the Dardanelles campaign had guns mounted forward of the conning tower while at Malta Dockyard. [1]

E-Class submarines had wireless systems with 1 kilowatt (1.3 hp) power ratings; in some submarines, these were later upgraded to 3 kilowatts (4.0 hp) systems by removing a midship torpedo tube. Their maximum design depth was 100 feet (30 m) although in service some reached depths of below 200 feet (61 m). Some submarines contained Fessenden oscillator systems.[3]

Crew

Her complement was three officers and 28 men.[3]
