NATO says since March 31, 178 sorties have been accomplished, but not all were air strikes.

So far, 14 member countries have participated in the operation, providing 205 fighters and 21 warships. The US Department of Defense has announced the end of US air strike missions. Since the start of the coalition operation nearly two weeks ago, the US has sent in 90 jet fighters.

Admiral Mike Mullen, chairman of the US Joint Chiefs of Staff, says these fighters will be on standby unless the situation in Libya turns extremely unfavorable. For now, the US air support will be limited to fueling, surveillance, and search and rescue operations.
