4/9/2013 - LANGLEY AIR FORCE BASE, Va. (AFNS) -- Air Force officials will begin to stand down active-duty combat units starting April 9 to ensure the remaining units supporting worldwide operations can maintain sufficient readiness through the remainder of the fiscal year.
The stand down is the result of cuts to Air Combat Command's operations and maintenance account, which must be implemented in part by flying approximately 45,000 fewer training hours between now and Oct 1.
As the Air Force's lead for Combat Air Forces, ACC manages the flying-hour programs for four major commands. This decision to stand down or curtail operations affects about one-third of the active-duty CAF aircraft -- including those assigned to fighter, bomber, aggressor and airborne warning and control squadrons -- stationed in the U.S., Europe and the Pacific.
