Ulithi Civil Airfield (IATA: ULI, FAA LID: TT02) is a public airport serving the island of Falalop, located in the Ulithi Atoll in the Caroline Islands, Federated States of Micronesia.

On 8 October the 51st Naval Construction Battalion began to improve the former Japanese airfield on Falalop, creating a coral-surfaced 3,500 feet (1,100 m) by 150 feet (46 m) runway, six taxiways, hardstands, lighting, a traffic-control tower, operations buildings, tank farm and a seaplane ramp.

[2] Marine Air Group 45 (MAG-45) deployed to Falalop in late September to establish base operations.

Fleet Air Wing One (FAW-1) was based at Falalop from 15 October until 30 December 1944 when it was relocated to Saipan.

The east end of the strip was extended approximately twenty feet past the natural shoreline.
