Design

German Type U 93 submarines were preceded by the shorter Type U 87 submarines. U-112 had a displacement of 798 tonnes (785 long tons) when at the surface and 996 tonnes (980 long tons) while submerged.[1] She had a total length of 71.55 m (234 ft 9 in), a pressure hull length of 56.05 m (183 ft 11 in), a beam of 6.30 m (20 ft 8 in), a height of 8.25 m (27 ft 1 in), and a draught of 3.76 m (12 ft 4 in). The submarine was powered by two 2,400 metric horsepower (1,800 kW; 2,400 shp) engines for use while surfaced, and two 1,200 metric horsepower (880 kW; 1,200 shp) engines for use while submerged. She had two propeller shafts and two 1.70 m (5 ft 7 in) propellers. She was capable of operating at depths of up to 50 metres (160 ft).[1]

The submarine had a maximum surface speed of 16.4 knots (30.4 km/h; 18.9 mph) and a maximum submerged speed of 8.4 knots (15.6 km/h; 9.7 mph).[1] When submerged, she could operate for 50 nautical miles (93 km; 58 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, she could travel 9,280 nautical miles (17,190 km; 10,680 mi) at 8 knots (15 km/h; 9.2 mph). U-112 was fitted with six 50 centimetres (20 in) torpedo tubes (four at the bow and two at the stern), twelve to sixteen torpedoes, one 10.5 cm (4.1 in) SK L/45 deck gun, and one 8.8 cm (3.5 in) SK L/30 deck gun. She had a complement of thirty-six (thirty-two crew members and four officers).[1]

gollark: But there are an infinitely large number of possible gods, and some do weirder things like "punish/reward entirely at random", "have no interest whatsoever in humanity", "punish people who believe in other gods", and all that, and Pascal's Wager just *ignores* those.
gollark: Pascal's Wager might work if the only options are "no god" or "one god, and it's the one you believe in, and they'll reward you if you believe and punish you otherwise".
gollark: Also, I should be specific, "a god and associated religious claims", not just "a god".
gollark: Pascal's Wager is really stupid.
gollark: > I’d rather just have faith and get on with my lifeThis seems like a bizarre attitude, since if you... don't actually have evidence for a god at all... it's really weird for that belief to affect your decisions.
