Wartime History
Assigned to an unknown Kōkūtai (Air Group) or carrier detachment operating land based from Rabaul. During late February 1944 when the last flyable aircraft from Rabaul were withdrawn to Truk, this Kate remained behind, possibly due to damage or mechanical issues.
Afterwards, this Kate was repaired to flying condition at Vunakanau Airfield and was assigned to 105th Naval Base Unit part of the reborn "Rabaul Air Force". Tail number 302. By 1945, the exterior paint was weathered from being outdoors in the tropics and from constant use.
On April 22, 1945 an A6M2 Zero modified two seater pilot Shimbo with Ensign Chuhei Okubo overflew Seeadler Harbor off Manus Island at 14,000' and observed two "aircraft carriers" that were actually floating dry docks USS ABSD-2 (Auxiliary Floating Dry Dock 2) and USS ABSD-4 (Auxiliary Floating Dry Dock 4). Back at Rabaul, the Imperial Japanese Navy (IJN) 105th Naval Base Unit planned to strike the two "aircraft carriers" with two repaired Kates including this aircraft.
On April 27, 1945 at 8:10pm took off from Vunakanau Airfield armed with an aerial torpedo piloted by Ensign Tokuya Takahashi with navigator Ensign Chuhei Okubo (previously observer the No. 5 Kate from Shōkaku during the December 7, 1941 attack on Oahu bombing hangers at Kaneohe Field) and radio operator CPO Shigeo Terao on a mission to attack two American "aircraft carriers" (actually floating dry docks) in Seeadler Harbor. The No. 2 aircraft (wingman) was B5N2 Kate pilot Nagai.
The two Kates flew westward at 6,000' then descended to 300' to 600' and flew through poor weather before reaching Rambutyo Island and proceeded to the target area flying at 150' and the pair spotted a searchlight at Momote Airfield and as the clouds cleared, Seeadler Harbor was fully illuminated with flood lights from numerous vessels at anchor and were not observing any black out, believing there were no Japanese aircraft capable of threatening the anchorage.
At 11:15pm the Kates commenced their attack run and became separated. This Kate aimed at an "aircraft carrier" actually Auxiliary Floating Dry Dock 2 (USS ABSD-2) and scored a hit damaging the dry dock. Returning alone, this Kate landed safely at Vunakanau Airfield on April 28, 1945 at 2:00am.
Meanwhile, the No. 2 aircraft B5N2 Kate pilot Nagai attacked the other "aircraft carrier" actually USS Auxiliary Floating Dry Dock 4 (ABSD-4) and scored a hit damaging the dry dock and returning form the mission this Kate and was either lost over the target area or lost on the return flight, likely due to bad weather and was reported as missing.
This Kate survived the Pacific War as one of the few Japanese aircraft in flyable condition at Rabaul. On August 15, 1945 after Japan surrendered, never painted in surrender markings (white or with green crosses) in accordance with the terms of the surrender.
On September 10, 1945 when the Allies occupied Rabaul, the Japanese requested permission to surrender their flyable aircraft to an Air Force unit. Their request was granted and Japanese pilots were allowed to fly to the nearest Allied airfield. Around this time, the Kate was photographed at Vunakanau Airfield with a damaged propeller.
On September 18, 1945 surviving Japanese aircraft were flown from Vunakanau Airfield on a flight bound for Jacquinot Bay Airfield to formally surrender. Due to mechanical problems, this Kate was unable to participate and remained behind. Meanwhile, the other aircraft departed including A6M5 Zero 4043, A6M3 Zero 3479 and A6M5 Zero 4444 and Ki-46 Dinah 2783. Afterwards, this Kate was repaired by Japanese personnel at Vunakanau Airfield and was ready to fly by early October, 1945.
On October 14, 1945 after 9:00am took off from Vunakanau Airfield piloted by P.O. Goro Kataoka on a flight bound for Jacquinot Bay Airfield to formally surrender. After climbing to 1,000' rolled over and dove steeply back towards the runway and made a low pass over the runway as a goodbye pass then climbed to 2,000' and was joined by four Royal New Zealand Air Force (RNZAF) F4U Corsairs from No. 16 Squadron led by Bryan B. Cox. The Kate flew westward on the wrong course until Bryan B. Cox used hand signals to the Japanese pilot to signal a new course. Meanwhile E13A Jake took off from Simpson Harbor and flew to Jacquinot Bay Airfield to formally surrender. This was the last confirmed flight of Japanese aircraft in present day Papua New Guinea (PNG).
Wreckage
Afterwards, the Kate was parked at Jacquinot Bay Airfield and was photographed and inspected by Allied personnel. There is no indication it was ever flown again. When New Zealand personnel withdrew, this Kate was abandoned at Jacquinot Bay Airfield.
In the early 1970s, it remained on its landing gear, with only the left outer wing panel and engine cowling removed overgrown with vegetation.
By 1981, the wreckage was disassembled and taken from the airfield and moved near shore next to what had been the old district office, along with the wreckage of Ki-46 Dinah 2783. In the middle 1980s, Brian Bennett arranged for the engine to be transported to the Kokopo Museum for display. The rest of the aircraft remained at the old district office.
