UNDATED (CNN) -- The U.S. Air Force has begun grounding a third of its fighter jet fleet.
An Air Force spokesman says dozens of units in the U.S., Europe, and the Pacific will ultimately stand down.
The grounding will involve jets assigned to fighter, bomber, airborne warning and other squads.
It's the result of forced spending cuts from the government-wide austerity that began in March.
The Pentagon is expected to absorb about half of the $85 billion in sweeping budget cuts, called sequester, from the inability of Congress to reach a deal on deficit reduction.
