After liberating the airfield on 2 March 1944, the 40th Naval Construction Battalion repaired the airfield and the airfield became operational on 18 May 1944, although fighters were landing at the airfield only two days after occupation. The single runway was extended to 7,800 feet (2,400 m) long x 130 feet (40 m) wide with 75 feet (23 m) foot shoulders, constructed with a coral base with marsden matting covering 1,000 feet (300 m) at the ends of the runway. A 7,000 barrel fuel depot was set up at the airfield. The United States Navy established Aviation Repair and Overhaul Unit No.1 (AROU 1) in the spring of 1944 on Momote Airfield between Seeadler Harbor and the Bismarck Sea on Los Negros Island. AROU 1 conducted maintenance and testing of naval aircraft and supplied aircraft to naval forces for major assaults as far away as the Philippine Islands.
