CAP is also an acronym for Combat Air Patrol
, the practice of maintaining interceptor aircraft
aloft with the intent of preventing incursions on a specified area. U.S. Carrier battle group
s maintain a CAP at nearly all times. In the aftermath of the NY/DC bombings on 9/11/01
, it has been reported by noders that there are F-16
s and other types from the USAF
flying CAP over New York City
and Washington, D.C.
to prevent any aircraft from approaching.
Related term: BARCAP, for BARrier CAP. This means a set of CAP missions/units whose purpose is to prevent other aircraft from crossing a designated 'line' or 'barrier' as opposed to responding to incursions into an area.
