Kampon water-tube boilers. The turbines were designed to produce 38,500 shaft horsepower (28,700 kW), which would propel the ships at 37.25 knots (68.99 km/h; 42.87 mph). The ships carried 420 metric tons (413 long tons) of fuel oil which gave them a range of 4,000 nautical miles (7,400 km; 4,600 mi) at 15 knots (28 km/h; 17 mph). Their crew consisted of 150 officers and crewmen.[3]
The main armament of the Mutsuki-class ships consisted of four
launched on 28 April 1927[4] and completed on 31 October 1927. Originally commissioned simply as Destroyer No. 33, the ship was assigned the name Mochizuki on 1 August 1928.[3] In the late 1930s, the ship participated in combat in the Second Sino-Japanese War, covering the landings of Japanese troops in central and southern China
.
Pacific War
At the time of the
Japanese Special Naval Landing Forces
(SNLF) troops.
After taking heavy losses (including Kisaragi and Hayate), the Japanese force withdrew before landing. This was the first Japanese defeat of the war, and also the only occasion in World War II when an
amphibious assault was repulsed by shore-based guns.[5]Mochizuki returned on December 23 with the second Wake Island invasion force before sailing back to Kwajalein.[6]
The ship escorted a convoy from Kwajalein to the naval base at
Operation SR (the invasion of Lae and Salamaua on New Guinea), and in April, covering landings on the Admiralty Islands.[7] During the Battle of the Coral Sea from 7–8 May 1942, Mochizuki was assigned to the Operation Mo invasion force for Port Moresby. After that operation was cancelled, it returned to Truk, escorting airfield construction convoys between Truk, Lae and Guadalcanal until recalled to Japan in mid-July for refitting.[6]
After repairs were completed at
IJN 8th Fleet. At the end of September, Mochizuki sortied with the destroyer Isokaze to rescue survivors from the destroyer Yayoi on Normanby Island. On 14–15 October Mochizuki provided cover for the cruisers Kinugasa and Chōkai during a bombardment of Henderson Field.[8] Throughout November, Mochizuki made numerous “Tokyo Express” troop transport runs to Guadalcanal. On one of these runs (8 November), she was hit by a dud torpedo from PT-61. On another run (13–15 November), she assisted Amagiri
in rescuing 1500 survivors from the torpedoed Nagara Maru and Canberra Maru transports.
On 1 December 1942, Mochizuki was reassigned to the
. The damage was severe enough to warrant a return to Sasebo to the end of August. After returning to Rabaul at the end of September, Mochizuki resumed Tokyo Express operations
