ww2dbaseMogami was the lead ship of her class of cruisers. Her class of cruisers was uniquely designed to be lightweight yet still provided adequate armor; however, some design defects cracked hull welds during trials, returning her to the shipyards to repair the defects in the following year. During the Battle of Midway, she was under the command of Rear Admiral Takeo Kurita; after the Japanese carrier fleet was routed, Kurita's task force was recalled to rendezvous with Admiral Isoroku Yamamoto to the west, but the fleet was sighted by American submarine Tambor. During emergency maneuvers to avoid a possible torpedo attack by Tambor, Mogami turned to port to move away from the potential incoming torpedoes, and then turned back to catch up. Unfortunately, her crew did not see that, while performing evasive maneuvers, her sister ship Mikuma had navigated directly in her path. Last second maneuvers avoided a 90-degree collision, but she still rammed to the port side of Mikuma, rupturing Mikuma's fuel tank, causing her to leave a trail of oil in her wake. Mogami's bow was crushed, crumpled in for about 40 feet. The two ships slowed to about twelve knots while the other two ships, along with Kurita, continued to steam full speed toward the rendezvous point; although Mikuma was capable of steaming at a high speed, Captain Shakao Sakiyama chose to stay behind to escort the damaged Mogami. On 6 Jun 1942, aircraft from American carriers Enterprise and Hornet sent three attack waves against the two damaged cruisers, which found them by means of the oil trail. Mogami took a bomb on the seaplane deck and started a serious fire, killing a number of crewmen, including many wounded in the sick bay. In contrast to her sister ship Mikuma, Mogami had earlier decided to throw her torpedoes overboard, something Mikuma decided against. In hindsight it was one of the critical differences that led to Mogami's successful escape from battle and Mikuma's sinking. She continued to operate in the Japanese navy until the Leyte Campaign in Nov 1944 when she was damaged by American battleship gunfire and scuttled by Akebono.

Mogami Operational Timeline

1935年7月28日	Mogami was commissioned into service.
1942年3月1日	HMS Encounter, HMS Exeter, and USS Pope were sunk at the Second Battle of the Java Sea; the ships suffered 7, 54, and 1 killed, respectively. Meanwhile, at the Battle of Sunda Strait, Allied cruisers USS Houston and HMAS Perth intercepted a Japanese invasion force but were both sunk as they attacked; four Japanese transports and a minesweepers were sunk, but two of the transports were later refloated. Also on this date, Japanese troops landed on Java and immediately began marching for Batavia, with the Japanese 2nd Division capturing Serang and the 230th Infantry Regiment capturing Kalidjati airfield at Soebang en route. Finally, Japanese air raids at Surabaya damaged destroyer USS Stewart and Dutch destroyer Witte de With.
1942年4月1日	Vice Admiral Jisaburo Ozawa's Malaya Force, Second Expeditionary Fleet, departs Mergui, Burma and steams into the Bay of Bengal in the Indian Ocean Raids to attack merchant shipping. The force includes light carrier Ryujo and cruisers Chokai, Suzuya, Kumano, Mikuma, Mogami, and Yura.
1942年4月5日	Following Admiral Jisaburo Ozawa’s force’s attack on the British naval base at Colombo, Ceylon, the force is split creating a Northern Group commanded by Rear Admiral Takeo Kurita consisting of cruisers Kumano and Suzuya; the Center Group consisting of the carrier Ryujo and cruisers Chokai and Yura under Ozawa; and the Southern Group comprised of cruisers Mogami, and Mikuma under Captain Shakao Sakiyama for the purposes of smaller raids against merchant shipping.
1942年4月6日	Sakiyama's Southern Group of Mogami, Mikuma and destroyer Amagiri sank four merchantmen totaling 19,000 tons with two of them finished off with torpedoes from Amagiri.
1942年4月11日	Jisaburo Ozawa's Force arrived at Singapore to conclude a successful sortie into the Indian Ocean.
1942年6月5日	Japanese cruiser Kumano was leading a column of sister Mogami-class cruisers Suzuya, Mikuma, and Mogami withdrawing from Midway. Kumano spotted the surfaced American submarine USS Tambor and ordered an emergency 45-degree turn to starboard, but Mikuma mistakenly made a 90-degree turn. Mogami rammed Mikuma on the portside below the bridge crumpling 40-feet of Mogami’s bow and piercing Mikuma’s fuel tanks, causing her to leak oil uncontrollably. This trailing oil slick led to Mikuma’s demise the following day.
1943年10月17日	Yamato, Musashi, Fuso, Nagato, Kongo, Haruna, Shokaku, Zuikaku, Takao, Atago, Maya, Chokai, Mogami, Suzuya, Tone, Chikuma, Agano, Oyodo, and a destroyer screen sortied from Truk, Caroline Islands to Eniwetok, Marshall Islands with Combined Fleet under Admiral Mineichi Koga's command in response to US Task Force 16 carrier raids on Wake Island.
1943年10月19日	Yamato, Musashi, Fuso, Nagato, Kongo, Haruna, Shokaku, Zuikaku, Takao, Atago, Maya, Chokai, Mogami, Suzuya, Tone, Chikuma, Agano, Oyodo, and a destroyer screen arrived at Eniwetok Atoll, Marshall Islands.
1943年10月23日	Yamato, Musashi, Fuso, Nagato, Kongo, Haruna, Shokaku, Zuikaku, Takao, Atago, Maya, Chokai, Mogami, Suzuya, Tone, Chikuma, Agano, Oyodo, and a destroyer screen departed Eniwetok Atoll, Marshall Islands and sortied to a position 250 miles south of Wake Island.
1943年10月26日	Yamato, Musashi, Fuso, Nagato, Kongo, Haruna, Shokaku, Zuikaku, Takao, Atago, Maya, Chokai, Mogami, Suzuya, Tone, Chikuma, Agano, Oyodo, and a destroyer screen arrived at Truk, Caroline Islands.
1943年11月5日	During the US raid on Rabaul, New Britain, Mogami was hit on the main deck between No. 1 and No. 2 turrets, killing 19; skilled flooding of the forward magazine prevented detonation.
1943年11月6日	Mogami departed Rabaul, New Britain for Truk, Caroline Islands to receive temporary repairs.
1944年3月8日	Zuikaku departed western Seto Inland Sea with B6N1 and A6M5 aircraft aboard for 601st Naval Air Group at Singapore; she was escorted by Kongo, Haruna, Mogami, Akigumo, Kazagumo, and Asagumo.
1944年3月11日	USS Lapon made contact with the Japanese carrier group centered around Zuikaku at around 1228 hours in the Pacific Ocean; she lost contact with the Japaese ships at around 1314 hours.
1944年3月14日	Zuikaku and Mogami arrived at Seletar, Singapore.
