2013 Sequestration

Air Combat Command officials announced a stand down and reallocation of flying hours for the rest of the fiscal year 2013 due to mandatory budget cuts. The across-the board spending cuts, called sequestration, took effect 1 March when Congress failed to agree on a deficit-reduction plan.

Squadrons either stood down on a rotating basis or kept combat ready or at a reduced readiness level called “basic mission capable” for part or all of the remaining months in fiscal 2013. This affected the 391st Fighter Squadron with a stand-down grounding from 9 April-30 September 2013.
