RMAF Butterworth Air Base — Butterworth, Malaysia

RMAF Butterworth Air Base is a Royal Malaysian Air Force installation in Butterworth, on the Malaysian mainland across the strait from Penang Island. Just 11 feet separates the base from sea level, and a single runway covers its operations, which remain military rather than open to commercial passengers. Coded BWH, it supports Royal Malaysian Air Force activity across the northern peninsula region, with Butterworth's coastal, low-lying position making it a practical site for operations near the Strait of Malacca. Civilian travelers heading to Penang typically use Penang International Airport instead, since BWH offers no scheduled passenger service and access stays restricted to military and authorized personnel.
