The most important Navy-Marine Corps contribution to the air war over Yugoslavia—Operation Allied Force—probably was the EA-6B Prowler electronic attack aircraft. Navy and Marine Prowlers provided protection for allied strike and other air missions during the conflict, seeking out hostile radar emissions and, when detected, jamming them.
Of 19 active and reserve Navy and Marine Corps squadrons—each with four aircraft—10 1/2 squadrons were forward deployed during the Kosovo campaign (the half squadron being a two-plane detachment from reserve squadron VAQ-209). At the height of the air campaign, six squadrons were flying from Aviano, Italy, in support of Allied Force and two squadrons were on board carriers. Two squadrons—one flying from Saudi Arabia, and one flying from a base in Turkey—were participating in the enforcement of no-fly zones over southern and northern Iraq, respectively. In addition, a Marine Prowler squadron was ashore in Japan, to support possible allied air operations against North Korea.
