RAAF Base Learmonth is located on the North West Cape peninsula of Western Australia, approximately 30 kilometres south of Exmouth.
It is a Forward Operating Base (FOB) that is used regularly for Operations, Exercises and Defence Aid to the Civil Community tasking.
The base was established in the 1950s to provide support for land, air and sea operations aimed at securing Australia's northern approaches. During World War II, the (then) Learmonth Airfield, also known as 'Potshot', provided protection for the US Navy's submarine base in the Exmouth Gulf. It also housed a variety of Air Force radar stations, providing early warning of enemy movements.
Following World War II, the airfield was upgraded by No 5 Airfield Construction Squadron in the early 1970s.
