Patrol Boat No. 105 (第百五號) (ex-Arayat) was a formerPhilippine Commonwealth customs inspection and enforcementcutter that was sunk by the Japanese during theinvasion of the Philippines and later raised and designated as apatrol boat in theImperial Japanese Navy.
On 6 December 1930, she was ordered by the United StatesBureau of Insular Affairs from the German shipbuilderSchichau-Werke, the third of threecutters ordered[1][2] from Schichau-Werke to serve with the Bureau of Customs as inspection and enforcement ships (the other two were 667 GRTsister shipsCanlaon andBanahao, both later converted tolighthouse tenders).[2][3] She waslaid down at Schichau'sDanzig shipyard,launched on 9 May 1931, and delivered on 13 August 1931.[2][3]
During theJapanese invasion the Philippines, she returned to her home port ofManila where theAsiatic Fleet had retreated. On 27 December 1941, Japanese attack planes from the 1stKōkūtai and theTakao Kōkūtai attackedManila Bay[4] settingArayat, her fellow customs cutterMindoro, and the motor vesselEthel Edwards ablaze while also sinking the lighthouse tenderCanlaon outright, and so heavily damaging the steamshipTaurus, her crew was forced to scuttle her.[4]
She was raised by theImperial Japanese Navy and rebuilt at the No. 103 Repair Facility at Cavite Naval Base.[5] On 1 September 1943, she was renamedPatrol Boat No. 105, and registered in theSasebo Naval District, and assigned to the Third Expeditionary Fleet,Southwest Area Fleet, based out ofManila.[6][7]
On 5 October 1944, she leftMiri along withType D escort shipsCD-18 andCD-26 providing escort forMyogi Maru,Heian Maru,Mikasa Maru, andTeiyu Maru (ex-Carignano) headed for Manila.[5] The convoy was carrying supplies for the besieged forces onLeyte Island. The convoy arrived safely at Manila on 2 November 1944. On 27 November 1944, she departed Manila as part of convoy TA-6 withNo.28-classsubmarine chasersCH-45 andCH-53 and freightersShinsho Maru andShinetsu Maru.[5] On 28 November 1944, the convoy arrived safely atOrmoc Bay,Leyte.[5] The three escorts were assigned to guard the entrance to the harbor while the transports unloaded.[5] They were soon confronted by American PT boats,PT-127 andPT-331 who each launched 4 torpedoes sinkingCH-53 at (10°59′N124°33′E / 10.983°N 124.550°E /10.983; 124.550) and heavily damagingPB-105 which was run aground and abandoned (the Americans capture her hulk on 8 December 1944).[5] The transports were able to unload their much-needed supplies although after departing,Shinetsu Maru andCH-45 were sunk by American planes on 29 November 1944 andShinsho Maru met the same fate on 30 November 1944.[8]
On 10 January 1945,PB-105 was struck from theNaval List.[5]
