Turtle Bay Airfield or Fighter Field #1 is a former World War II airfield on the island of Espiritu Santo in the New Hebrides Islands at the Espiritu Santo Naval Base.

[1] A group of Seebees from the 3rd Construction Battalion detachment (1st Naval Construction Battalion) with an anti-aircraft battery from the 4th Defense Battalion and a company of colored infantrymen arrived on Santo on 8 July 1942 to begin work on Turtle Bay airfield to bomb the airfield the Japanese were building on Guadalcanal.

[2][3] The Seebees were given twenty days in which to construct the airfield, assisted by 295 infantrymen, 90 Marines and 50 natives.

Working around the clock, a 6,000 feet (1,800 m) runway was cleared and surfaced with coral within the time given.

The planes were fueled from drums and carried out their first attack on Japanese forces on Guadalcanal on 30 July.
