Japanese Maritime Self Defence Forces (JMSDF) Oyashio class Submarine SS-590 Oyashio ★Oyashio class Spec★ Displacement: 2750 tonnes (surfaced), 4000 tonnes (submerged) Length: 81.7 m Beam: 8.9 m Draught: 7.4 m Propulsion: 1-shaft diesel-electric 3400 SHP (surfaced), 7700 SHP (submerged) Speed: 12 knots (surfaced), 20 knots (submerged) Complement: 70 (10 officers) Sensors and processing systems: Sonar: Hughes/Oki ZQQ 5B/6 hull-mounted sonar, flank arrays, 1 towed array. Radar: JRC ZPS 6 I-band search radar. Armament: 6 × 21 inch (533 mm) torpedo tubes for Type 89 torpedoes, or UGM-84 Harpoon http://en.wikipedia.org/wiki/Oyashio_class_submarine The Oyashio class represents departure form previous submarines of the Maritime Self Defense Force, which have used a tear drop hull form. This latest and most powerful submarine changed to a "leaf coil" hull form. It incorporates not only a different hull form, but unlike conventional type of structure which was a double hull system, the Oyashio has a single hull / double hull compound design. The design of the Oyashio started by seriously considering the arrangement of the sensor first, after which the entire layout was decided. Previously the sonar was mounted in only the bow, but this new model which designates entire hull as the sensor, equipped with a conformal sonar arranged on the hull side to provide improved detection efficiency. In addition the combat intelligence processing system of new model also improves attack ability. The position of the torpedo tube differs from conventional type, with the bow torpedo tube placement decided after the arrangement of the sensor. The acoustic stealth efficiency of the hull is improved by installing sound-absorbing rubber tiles on the hull. A reduction of the crew is due to advanced new technology, with a smaller crew compared with similar types of submarine in other countries. http://www.globalsecurity.org/military/world/japan/oyashio.htm yt:quality=high japanese japan navy jmsdf military ijn pacific diesel electric class submarine silent hunter SS-501 SS-511 SS-590 Oyashio Soryu Kilo Lada Upholder Gotland type212 type214 AIP おやしお 潜水艦
