The 570th Composite Tactical Wing is the Air Force Component of the Western Command based on Puerto Princesa City, Palawan. While its mission - to perform tactical air operations within its assigned AOR and maintain base services at its location - is non-specific, the wing actually serves as the forward deployment point in Western Philippines and launch pad for operations over the Kalayaan Chain of Islands. Deployed air assets such as the UH-1H, N-22B, S-211, and F-5 at Antonio Bautista Air Base assure the Western Command of its tactical control of the area.
