Japanese heavy cruiser Mogami
The Mogami-class ships were constructed as “light cruisers” due to limitations of the Washington Naval Treaty. Therefore, to by pass these limitations they made them with the original and unique setting of five triple 6.1″ 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″ guns.
This model shows the configuration of Mogami as light cruiser (as of 1936) with a unique weapon setting of five triple 6.1″(150 mm) dual purpose guns.
In this model, after 1937, the Mogami has been converted into AIRCRAFT CARRYING CRUISER. Technically, it was converted first to heavy cruiser with five twin 8″ guns. Later, after being damaged in Midway, June 1942, it was refitted as aircraft carrying cruiser.
In 1937 all four Mogami-class ships were “converted” to heavy cruisers in this fashion. Mogami served in numerous combat engagements in World War II including The Battle of Sunda Strait (1942), Indian Ocean Raids (1942), Battle of Midway (1942), Battle of Philippine Sea (1944), Battle of Leyte Gulf (1944), Battle of the Surigao Strait (1944). She was sunk at the Battle of Leyte Gulf in October 1944.
On 25 October, between 03:00-03:30, the Japanese force was attacked by American PT boats and destroyers. Battleships Fusō and Yamashiro were hit by torpedoes and destroyers Yamagumo was sunk, and Michishio disabled, but Mogami was not hit. Fusō and Yamashiro both later sank. Between 03:50–04:02 hours on 25 October, after entering the Surigao Strait, Mogami was struck by four 8-inch (200 mm) shells, which destroyed both the bridge and the air defense center. Both the captain and executive officer were killed on the bridge, and the chief gunnery officer assumed command. While attempting to retire southward, the flagship of Admiral Shima, Nachi, collided with Mogami. Nachi’s bow was damaged and she began to flood. Mogami was holed starboard above the waterline, but fires ignited five torpedoes that exploded and disabled her starboard engine. Between 05:30-05:35, the crippled Mogami was hit again by ten to twenty 6-inch and 8-inch shells from USS Portland (CA-33), USS Louisville (CA-28) and USS Denver (CL-58). At 08:30, Mogami ’s port engine broke down. At 0902, while adrift, she was attacked by 17 TBF Avengertorpedo-bombers from Task Group 77.4.1 and was hit by two 500-lb. bombs. At 1047, Mogami ’s crew abandoned ship, and she stayed afloat for the next 2 hours. At 1240, Akebono scuttled her with a single Type 93 “Long Lance” torpedo. She finally sank at 1307, at. Akebono rescued 700 survivors, but 192 crewmen perished with the ship.
