MASS-2

Marine Air Support Squadron 2 (MASS-2) is a United States Marine Corps aviation command and control unit, originally activated in 1944 as Headquarters Squadron 43 during World War II. The unit played a critical role in providing direct air support coordination for Marine ground forces during key Pacific campaigns, including Okinawa. Re-designated as MASS-2 in 1950, it saw extensive service during the Korean and Vietnam Wars, supporting combat operations by coordinating close air support and airspace management. Today, MASS-2 remains an integral part of the 1st Marine Aircraft Wing, based in Okinawa, Japan, and continues to provide vital air support control capabilities in the Indo-Pacific region.
