Japanese cruiser Suzuya (1934)

Built under the Maru-1 Naval Armaments Supplement Programme, the Mogami-class cruisers were designed to the maximum limits allowed by the Washington Naval Treaty, using the latest technology. This resulted in the choice of the dual purpose (DP) 15.5 cm/60 3rd Year Type naval guns as the main battery in five triple turrets capable of 55° elevation. These were the first Japanese cruisers with triple turrets. Secondary armament included eight 12.7 cm/40 Type 89 naval guns in four twin turrets, and 24 Type 93 Long Lance torpedoes in four rotating triple mounts. To save weight, electric welding was used, as was aluminum in the superstructure, and a single funnel stack. New impulse geared turbine engines, driving four shafts with three-bladed propellers gave a top speed of , which was better than most contemporary cruiser designs and the Mogami class had twin balanced rudders, rather than the single rudder of previous Japanese cruiser designs. The class was designed from the start to be upgraded into heavy cruisers with the replacement of their main battery with 20 cm/50 3rd Year Type naval guns in twin turrets. However, in initial trials in 1935, and were plagued with technical problems due to their untested equipment, welding defects, and also proved to be top-heavy with stability problems in heavy weather. Both vessels, and their yet-to-be-completed sisters, and Suzuya underwent a complete and very costly rebuilding program. Once rebuilt, the design, with its very high speed, armor protection, and heavy armament was among the best in the world during World War II. ==Service career==

Early career . Suzuya was launched on 20 November 1934 at Yokosuka Naval Arsenal in a ceremony attended by Emperor Hirohito. Following the Japanese ship-naming conventions, the ship was named after the River on Karafuto (present day Sakhalin, Russia). She was completed in January 1936, but on completion was immediately placed in the reserves while waiting for dry dock space to permit reconstruction and modifications based on experience gained during trials of Mogami to strengthen her welds, and to add bulges to her hull to reduce weight. She was officially commissioned on 31 October 1937; however instead of entering active service, she immediately returned to dry dock for refit work to upgrade her main battery to the heavy cruiser format with 20 cm/50 3rd Year Type naval guns. In total the commerce raiding expedition sank over twenty ships during their brief stay in the Bay of Bengal. Afterwards, Suzuya was withdrawn back to Kure for repairs, and was then sent to Guam to join the Midway Invasion Task Force. Battle of Midway On 5 June, Admiral Isoroku Yamamoto, CINC of the Combined Fleet ordered CruDiv 7 to shell Midway Island in preparation for a Japanese landing. CruDiv 7 and DesDiv 8 were away from the island, so they made a high-speed dash at . The sea was choppy and the destroyers lagged behind. At 2120, the order was canceled. However, this dash placed CruDiv 7 within torpedo range of the submarine , which was spotted by Kumano. Kumano signaled a 45° simultaneous turn to starboard to avoid possible torpedoes. The emergency turn was correctly executed by the flagship and Suzuya, but the third ship in the line, Mikuma, erroneously made a 90° turn. Behind her, Mogamis navigator, watching Suzuya, did not see Mikumas movement and turned 45° as commanded. This resulted in a collision in which Mogami rammed Mikumas portside, below the bridge. Both vessels were severely damaged. Suzuya returned to Kure on 23 June and CruDiv 7 was transferred to the IJN 3rd Fleet. After returning to Singapore, CruDiv 7 (Suzuya and Kumano) were tasked with covering the Invasion of Burma from 28 July 1942. While in the Straits of Malacca, Suzuya was attacked by Royal Netherlands Navy submarine , which fired four torpedoes, but missed. However, with the American invasion of Guadalcanal on 7 August, Suzuya was quickly recalled to the Pacific front. Operations in the Solomon Islands On 24 August 1942, CruDiv 7 joined Vice Admiral Chuichi Nagumo's Carrier Strike Force (, , and ) with cruiser northeast of Guadalcanal. During the resultant Battle of the Eastern Solomons, aircraft from the carrier sank the aircraft carrier Ryūjō; but Suzuya was too far away to be in the combat. Suzuya subsequently patrolled between Truk and the Solomon Islands through the middle of October. On 26 October 1942, Nagumo's Carrier Strike force engaged the aircraft carriers , , battleship and cruiser in the Battle of Santa Cruz, sinking Hornet and damaging other ships. The battle was a long-range air battle, and again Suzuya was far enough away to avoid direct combat. In early November, CruDiv 7 was ordered to reinforce Vice Admiral Gunichi Mikawa's Eighth Fleet at Shortland, and participated on the bombardment of Henderson Field on Guadalcanal on 14 November. Suzuya, cruisers , , Chōkai, Kinugasa and and destroyers , , , , and bombarded the air strip with 989 203 mm (8 in) shells. On withdrawing, the task force was attacked by the submarine (which missed) and aircraft from Enterprise and Guadalcanal. Kinugasa was sunk, Chōkai and Maya were damaged; Suzuya escaped unscathed, and through early January 1943 continued her patrols and coverage of transport convoys between Truk, Kavieng and Rabaul. Suzuya returned to Kure on 12 January 1943 for repairs, at which time additional AA guns and a Type 21 air search radar were installed. She returned to Kure again on 6 April, at which time her dual Hotchkiss M1929 machine gun| machine guns were replaced by two triple-mount Type 96 25 mm AT/AA Guns. Suzuya departed Yokosuka on 16 June 1943, with another major resupply convoy to the Solomon Islands, and shuttled back and forth from Truk to Rabaul through the end of the year. On 18 July, Suzuya was attacked by Guadalcanal-based United States Marine Corps TBM Avengers off Kolombangara, but escaped without damage. On 3 November, Suzuya with Mogami and Chikuma were dispatched from Rabaul to bombard American forces that just landed at Empress Augusta Bay, Bougainville Island, but the raid was prevented to reach gun range thanks to US Admiral Merill's victory, sinking the cruiser Sendai. Suzuya was back in Rabaul harbor on 5 November, when the United States launched an attack with 97 planes from the carriers Saratoga and . Suzuya was one of the few ships not hit in the raid. On 1 February, Suzuya assisted with the evacuation of Truk. Suzuya went into refit at Singapore on 24 March, at which time an additional eight single-mount Type 96 25 mm AA guns were installed. Battle of the Philippine Sea On 13 June 1944, Admiral Soemu Toyoda, CINC, Combined Fleet, activated the "A-Go" plan for the defense of the Mariana Islands. Suzuya was assigned to Admiral Kurita's "Force C" with the battleships , and aircraft carriers Zuihō, , , and cruisers , , Maya, Chōkai, Kumano, Chikuma, , and . Later in the day, the Mobile Fleet's aircraft attacked Task Force 58 off Saipan, but suffered overwhelming losses in the "Great Marianas Turkey Shoot". At 2030 on 20 June, two hours after she was hit by torpedoes by Grumman TBM Avengers from the aircraft carrier , the exploded and sank. That night, Suzuya retired with the remnants of the Japanese fleet to Okinawa. Back in Kure on 25 June 1944, Suzuya was refit once again. Four triple-mount and 10 single-mount Type 96 25 mm AA guns were installed, bringing the total to 50 barrels (14×3 and 18×1) and a Type 22 surface search radar and Type 13 air-search radar were fitted. On 8 July, Suzuya departed Kure back for Singapore and Brunei, and was involved in fleet training and patrols in the Singapore-Brunei area through October. By this time, her Type 22 Kai 4M radar was upgraded to Kai 4S for fire control. Battle of Leyte Gulf In late October, the Japanese fleet assembled in Brunei in response to the threatened American invasion of the Philippines. On 25 October 1944, in the Battle off Samar, Suzuya engaged the three "Jeep carriers" in American Task Group 77.4, but was attacked by ten TBM Avenger torpedo-bombers. A near-miss destroyed her port propeller. At 1050, Suzuya was attacked by 30 other carrier aircraft. Another near-miss caused the Long Lance torpedoes in Suzuyas No. 1 torpedo tubes to explode, which in turn started other fires and damaged the starboard engine rooms and the No. 7 boiler room. Suzuya was abandoned at 1150, and at 1322 sank at . Destroyer took off Captain Teraoka and 401 crewmen. US warships later rescued more sailors. Suzuya was removed from the navy list on 20 December 1944. Though it has yet to be located, the wreck of the Suzuya is believed to lie in some of water, making her one of the deepest shipwrecks on record. ==Notes==
