Design
editLike all post-E8 British E-class submarines, E27 had a displacement of 662 long tons (673 t) at the surface and 807 long tons (820 t) while submerged. She had a total length of 180 feet (55 m)[1] and a beam of 22 feet 8.5 inches (6.922 m). She was powered by two 800 horsepower (600 kW) Vickers eight-cylinder two-stroke diesel engines and two 420 horsepower (310 kW) electric motors.[2][3] The submarine 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). British E-class submarines had fuel capacities of 50 long tons (51 t) of diesel and ranges of 3,255 miles (5,238 km; 2,829 nmi) when travelling at 10 knots (19 km/h; 12 mph).[1] E27 was capable of operating submerged for five hours when travelling at 5 knots (9.3 km/h; 5.8 mph).
E27 was constructed with a 12-pounder 76 mm (3.0 in) QF gun mounted forward of the conning tower, although this was later removed. She had five 18 inch (450 mm) torpedo tubes, two in the bow, one either side amidships, and one in the stern; a total of 10 torpedoes were carried.[2]
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.[1]
Crew
editHer complement was three officers and 28 men.[1]
