Naval Outlying Field Coupeville

Naval Outlying Field Coupeville is a military airport located two miles (3 km) southeast of Coupeville, Washington, in Island County. It is owned by the United States Navy. NOLF Coupeville nearly touches State Route 20 and is about 10 miles south of NAS Whidbey Island.

NOLF Coupeville is also known as OLF Coupeville and supports day and night Field Carrier Landing Practice (FCLP) operations by US Navy EA-18G Growler and EA-6B Prowler electronic warfare aircraft based out of NAS Whidbey Island. The OLF has been in the US Navy since September 1943 and involves, "aircraft flying in patterns to practice touch-and-go landings. Each aircraft in turn approaches the runway and touches down, immediately takes off again then loops around and prepares for another landing. Each aircraft makes multiple touch-and-go landings during these training events. In order to properly prepare crews for the dynamic nature of shipboard flying, it is imperative to replicate carrier landing experience as much as possible. This includes flying at appropriate altitudes and speeds as well as having practice fields at or near sea level. ... OLF Coupeville is ideal for this training practice due to its remote location and low ambient lighting. It more closely replicates true landings aboard an aircraft carrier."
