IJN Shinano (Yamato Class)

thingiverse

Shinano (信濃), was an aircraft carrier built by the Imperial Japanese Navy (IJN) during World War II, the largest such built up to that time. Laid down in May 1940 as the third of the Yamato-class battleships, Shinano's partially complete hull was ordered to be converted to a carrier following Japan's disastrous loss of four fleet carriers at the Battle of Midway in mid-1942. Her conversion was still not finished in November 1944 when she was ordered to sail from the Yokosuka Naval Arsenal to Kure Naval Base to complete fitting out and transfer a load of 50 Yokosuka MXY7 Ohka rocket-propelled kamikaze flying bombs. Hastily dispatched, she had an inexperienced crew and serious design and construction flaws, lacked adequate pumps and fire-control systems, and did not carry a single aircraft. She was sunk en route, 10 days after commissioning, on 29 November 1944, by four torpedoes from the U.S. Navy submarine Archerfish. Over a thousand sailors and civilians were rescued and 1,435 were lost, including her captain. She remains the largest warship ever sunk by a submarine.[1] Name: Shinano Namesake: Shinano Province Builder: Yokosuka Naval Arsenal Laid down: 4 May 1940 Launched: 8 October 1944 Completed: 19 November 1944 (for trials) Fate: Sunk by the submarine USS Archerfish, 29 November 1944 General characteristics Type: Aircraft carrier Displacement: 65,800 metric tons (64,800 long tons) (standard) 69,151 metric tons (68,059 long tons) (normal) Length: 265.8 m (872 ft 2 in) (o/a) Beam: 36.3 m (119 ft 1 in) Draught: 10.3 m (33 ft 10 in) Installed power: 150,000 shp (110,000 kW) 12 × Kampon water-tube boilers Propulsion: 4 × shafts 4 × geared steam turbines Speed: 28 knots (52 km/h; 32 mph) Range: 10,000 nmi (19,000 km; 12,000 mi) at 18 knots (33 km/h; 21 mph) Complement: 2,400 Armament: 8 × twin 12.7 cm Type 89 dual-purpose guns 35 × triple 25 mm Type 96 AA guns 12 × 28 – 12 cm (4.7 in) AA rocket launchers Armor: Waterline belt: 160–400 mm (6.3–15.7 in) Flight deck: 75 mm (3.0 in) Aircraft carried: 47
