MCAF Kāne‘ohe Bayʻs Patrol Squadron 4 (VP-4) "Skinny Dragons" P-3C Orions have begun their "Aloha Deployment". Upon return form their deployment, they will transition to the P-8A Poseidon, and relocate to NAS Whidbey Island, WA. The "Skinny Dragons" are the first of three P-3C squadrons based at MCAF Kāne‘ohe Bay to make the transition and the move, and ends a 50-year run being based on O‘ahu. US Navy anti-submarine aircraft were once based at the now-closed NAS Barbers Point (now the Kalaeloa Airport).
