Design

Like all post-E8 British E-class submarines, E54 had a displacement of 662 tonnes (730 short tons) at the surface and 807 tonnes (890 short tons) while submerged. She had a total length of 180 feet (55 m)[1] and a beam length 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 tonnes (55 short tons) 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] E54 was capable of operating submerged for five hours when travelling at 5 knots (9.3 km/h; 5.8 mph).

E54 was armed with a 12-pounder 76 mm (3.0 in) QF gun mounted forward of the conning tower. 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]

gollark: Anyway, I'm hoping consumer AR-type things come before neural interfaces, and this seems fairly plausible right now.
gollark: Oh yes, just remove wires surgically implanted in your brain casually.
gollark: They could just mind-control me into recharging it.
gollark: If someone gets access to a computer in my *brain*, they can alter my beliefs and perceptions - subject me to horrible torture forever, make me an entirely different person, sort of thing.
gollark: Currently, if someone gets unauthorized access to my computer, at worst they will have access to a bunch of personal information and passwords, but I can change the passwords and wipe the computer, although it would be somewhat tedious.
