The U.S. Air Force Global Hawk unmanned aircraft based at Sigonella in Sicily, are likely to be pulled into combat duty to gauge damage done in the initial wave of strikes with Libya.
The early attacks on Libya's air defenses, in particular its SA-5 sites, were taken, in part, to make the environment more benign for Global Hawk overflights, suggests Vice Admiral Bill Gortney, who is the director of the Joint Staff. The Pentagon said on March 19 that it would take 6-12 hours to determine if the air defenses were down.
The bulk of the initial strikes occured around Tripoli and Misratah.
The early strikes did not involve EA-6B jamming support, since the U.S. and U.K. relied on cruise missiles to strike air defenses.
