caption_attribution_description: A Grumman EA-6B-30-GR Prowler (BuNo 158037) from Tactical Electronic Warfare Squadron VAQ-131 Lancers in flight. VAQ-131 was assigned to Carrier Wir Wing 14 (CVW-14) aboard the aircraft carrier USS Enterprise (CVAN-65) for a deployment to Vietnam from 12 September 1972 to 12 June 1973, this being the second EA-6B squadron to deploy to Vietnam. The EA-6B 15803 was later lost in a crash near Palermo, Sicily (Italy), on 16 December 1979, while in service with VAQ-134. 3 crewmen ejected safely, one was killed.
context_page_description: The Northrop Grumman EA-6B Prowler is a twin-engine, four-seat, mid-wing electronic-warfare aircraft derived from the A-6 Intruder airframe. The EA-6A was the initial electronic warfare version of the A-6 used by the United States Marine Corps and United States Navy. Development on the more advanced EA-6B began in 1966. An EA-6B aircrew consists of one pilot and three Electronic Countermeasures Officers, though it is not uncommon for only two ECMOs to be used on missions. It is capable of carrying and firing anti-radiation missiles, such as the AGM-88 HARM missile.
  The Prowler was in service with the U.S. Armed Forces from 1971 until 2019. It has carried out numerous missions for jamming enemy radar systems, and in gathering radio intelligence on those and other enemy air defense systems. 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. Following its last deployment in late 2014, the EA-6B was withdrawn from U.S.
context_section_description: The EA-6B entered service with Fleet Replacement Squadron VAQ-129 in September 1970, and Tactical Electronic Warfare Squadron 132 (VAQ-132) became the first operational squadron, in July 1971. This squadron began its first combat deployment to Vietnam on America 11 months later, soon followed by VAQ-131 on Enterprise and VAQ-134 on Constellation.  Two squadrons of EA-6B Prowlers flew 720 sorties during the Vietnam War in support of US Navy attack aircraft and USAF B-52 bombers.
  During the 1983 invasion of Grenada, four Prowlers supported the operation from USS Independence (CV-62).
  Following the Achille Lauro hijacking, on 10 October 1985 Prowlers from USS Saratoga (CV-60) provided ESM support during the interception of the EgyptAir 737 carrying four of the hijackers.
  Prowlers jammed Libyan radar during Operation El Dorado Canyon in April 1986. Prowlers from USS Enterprise (CVN-65) jammed Iranian Ground Control Intercept radars, surface-to-air missile guidance radars and communication systems during Operation Praying Mantis on 18 April 1988.
  A total of 39 EA-6B Prowlers were involved in Operation Desert Storm in 1991, 27 from six aircraft carriers and 12 from USMC bases. During 4,600 flight hours, Prowlers fired over 150 HARM missiles. Navy Prowlers flew 1,132 sorties and USMC flew 516 with no losses.
  With the retirement of the EF-111 Raven in 1998, the EA-6B was the only dedicated aerial radar jammer aircraft of the U.S. Armed Forces, until the fielding of the Navy's EA-18G Growler in 2009. The EA-6B has been flown in almost all American combat operations since 1972, and is frequently flown in support of the U.S. Air Force missions.
  In 2001, 124 Prowlers remained, divided between twelve Navy, four Marine, and four joint Navy-Air Force "Expeditionary" squadrons. A Joint Chiefs of Staff (JCS) staff study recommended that the EF-111 Raven be retired to reduce the types of aircraft dedicated to the same mission, which led to an Office of the Secretary of Defense (OSD) program memorandum to establish 4 land based "expeditionary" Prowler squadrons to meet the needs of the Air Force.
  Though once considered being replaced by Common Support Aircraft, that plan failed to materialize. In 2009, the Navy EA-6B Prowler community began transitioning to the EA-18G Growler, a new electronic warfare derivative of the F/A-18F Super Hornet. All but one of the active duty Navy EA-6B squadrons were based at Naval Air Station Whidbey Island. VAQ-136 was stationed at Naval Air Facility Atsugi, Japan, as part of Carrier Air Wing 5, the forward deployed naval forces (FDNF) air wing that embarks aboard the Japan-based George Washington. VAQ-209, the Navy Reserve's sole EA-6B squadron, was stationed at Naval Air Facility Washington, Maryland. All Marine Corps EA-6B squadrons were located at Marine Corps Air Station Cherry Point, North Carolina.
  In 2013, the USN planned to fly the EA-6B until 2015, while the USMC expect to phase out the Prowler in 2019.  The last Navy deployment was on George H.W. Bush in November 2014, with VAQ-134.  The last Navy operational flight took place on 27 May 2015.  Electronic Attack Wing, U.S. Pacific Fleet (CVWP), hosted a retirement commemoration for the EA-6B from 25 to 27 June 2015 at NAS Whidbey Island.
