Mogami Class Heavy Cruiser Suzuya pictured fitting out at Yokosuka Naval Arsenal on July 20th 1935...In late October, the Japanese fleet assembled in Brunei in response to the threatened American invasion of the Philippines. On October 25th 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 Suzuya's 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. Destroyer Okinami took off Captain Teraoka and 401 crewmen. US warships later rescued more sailors.

Mogami Class Heavy Cruiser Suzuya pictured on sea trials off Tateyama on August 18th 1937...She was launched on November 20th 1934 at Yokosuka Naval Arsenal in a ceremony attended by Emperor Hirohito. 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 October 31st 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. These upgrades were completed on September 30th 1939, at which time she was assigned to Kure Naval District as CruDiv7 of the IJN 2nd Fleet with her sister ships Mogami, Mikuma and Kumano. In late October, the Japanese fleet assembled in Brunei in response to the threatened American invasion of the Philippines. On October 25th 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 Suzuya's 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. Destroyer Okinami took off Captain Teraoka and 401 crewmen. US warships later rescued more sailors. Suzuya was removed from the navy list on December 20th 1944. Though it has yet to be located, the wreck of Suzuya is believed to lie in some 27,600 feet of water, making her one of the deepest shipwrecks on record.

Lead Ship, Light Cruiser Mogami pictured departing Kure Naval Arsenal for Sasebo on August 24th 1935...The ships were constructed as 'Light Cruisers' (per the Washington Naval Treaty) with five triple 155 mm dual purpose guns. They were exceptionally large for Light Cruisers, and the barbettes for the main battery were designed for quick refitting with twin 8-inch guns. In 1937 all four ships were 'converted' to Heavy Cruisers in this fashion. Mogami served in numerous combat engagements in World War II, until she was sunk at the Battle of Leyte Gulf in October 1944.

Lead Ship, Light Cruiser Mogami pictured on sea trials off Kure Naval Arsenal on March 10th 1935....The Mogami Class ships were constructed as 'Light Cruisers' (per the London Naval Treaty) with five triple 155 mm dual purpose guns. They were exceptionally large for Light Cruisers, and the barbettes for the main battery were designed for quick refitting with twin 8-inch guns. In 1937 all four ships were 'converted' to Heavy Cruisers in this fashion. Mogami served in numerous combat engagements in WWII, until she was sunk at the Battle of Leyte Gulf in October 1944.

Mogami Class Light Cruiser Mikuma pictured off Tosa on May 3rd 1939...Mikuma was completed at Mitsubishi's Nagasaki Shipyards on August 29th 1935.
Beginning in 1939, Mikuma was brought in for substantial reconstruction, replacing the triple 6 inch turrets with twin 8 inch guns (the 6 inch turrets going to Battleship Yamato). Torpedo bulges were also added to improve stability, but the increased displacement caused a reduction in speed..She was sunk by American aircraft during Battle of Midway, June 6th 1942.
