The Northrop Grumman
(formerly Grumman) EA-6B Prowler
is a twin-engine, mid-wing electronic warfare aircraft derived from the basic A-6 Intruder
airframe. The EA-6B has been in service with the U.S. Armed Forces
from 1971 through the present, during which it has carried out numerous missions for jamming enemy radar systems, and in gathering radio intelligence on those and other enemy air defense systems. In addition, the EA-6B is capable of carrying and firing anti-radiation missiles (ARM), such as the HARM missile. The aircrew of the EA-6B consists of one pilot and three Electronic Countermeasures Officers, though it is not uncommon for only 2 ECMOs to be used on missions.
From the 1998 retirement of the United States Air Force EF-111 Raven electronic warfare aircraft, the EA-6B was the only dedicated electronic warfare plane available for missions by the U.S. Navy, the U.S. Marine Corps, and the U.S. Air Force until the fielding of the Navy's EA-18G Growler in 2009.
