January 25 - March 2, 1944
After the February 29, 1944 US
Army 1st Cavalry Division landing on Los Negros, Momote Airfield was captured on March 2, 1944.
At the airfield, at least eight Ki-43 Oscars were surveyed by ATIU including: Ki-43
5807 (5907), Ki-43 6132, Ki-43 6139, Ki-43 6145,
Ki-43 6150, Ki-43 6153, Ki-43 6155, Ki-43 6150 (had old style leak proofing).
The others had more modern self-sealing tanks.
Immediately, Momote Airfield was repaired for use American. By
March 16, 1944 Momote was in use and further expansions were underway and by by May 18 fighters were operating from this location. The runway was surfaced
with coral and connected to taxiways, hard stands and storage areas including over 7,000 barrels of
bulk petroleum for flight operations. A causeway was built over a swampy area and created a link between Los Negros and Manus Island. By 1945, the runway measured 7,000' in length.
Momote Airfield was used by American aircraft including the 13th Air Force, 7th Air Force bombers flying via Kwajalein for bombing missions against Guam that landed at Los Negros to refuel and rearm before returning to bomb again then return to Kwajalein. Also used by United States Navy (USN) and Royal Australian Air Force (RAAF). During 1945, NATS (Naval Air Transport Service) operated R4D's and C-54s at the center of the airfield, with flights to Southern Philippines.

Richard Dunn adds:
documents contradict this evidence somewhat. They show 6131 left
at Hyane but 6132 turned into the
Branch Depot at Hollandia. Looks like either the Americans or
Japanese made a typo. Ki-43 6136 being turned into the 209
Branch Depot salvage dump "completely damaged" in Jan
44. Another interesting tidbit the 28 (apparently) fighters arrived
by January 44 were equipped with one "fixed machine cannon model
3" and one 'experimental 12.7mm'.
Still in use today as "Momote Airport" or "Momote Manus Airport". The runway measures 1,870m x 45m with an orientation of 16/34 at an elevation of 5'. Airport codes: ICAO: AYMO and IATA: MAS.
