Eglin Air Force Base (AFB) (IATA: VPS, ICAO: KVPS, FAA LID: VPS) is a United States Air Force base located approximately 3 miles (5 kilometers) southwest of Valparaiso, Florida in Okaloosa County.
The host unit at Eglin is the 96th Test Wing (formerly the 96th Air Base Wing). The 96 TW is the test and evaluation center for Air Force air-delivered weapons, navigation and guidance systems, Command and Control systems, and Air Force Special Operations Command systems.
Eglin AFB was established in 1935 as the Valparaiso Bombing and Gunnery Base. It is named in honor of Lieutenant Colonel Frederick I. Eglin (1891–1937), who was killed in a crash of his Northrop A-17 pursuit aircraft on a flight from Langley to Maxwell Field, Alabama.
