EA-6B Prowler is a twin-engine, mid-wing electronic warfare aircraft manufactured by Grumman as a modification of the basic A-6 Intruder airframe. Originally, the EA-6A "Electric Intruder" was developed for the United States Marine Corps in the 1960s to replace the EF-10B Skyknight. It was a direct conversion of the standard two-seat A-6 Intruder airframe fitted with electronic warfare (EW) equipment. The EA-6A was used by three USMC squadrons during Vietnam War. A total of 27 were built with 15 of those being new builds. Most were retired in the 1970s with the last few retiring in the 1990s.
The much more advanced and substantially redesigned EA-6B was developed beginning in 1966 as a replacement for EKA-3B Skywarriors for the United States Navy. The forward fuselage was lengthened for a larger four-seat cockpit and the antenna fairing added to the tip of the vertical stabilizer.
According to news reports, the Prowler has been used in anti-improvised explosive device operations in the current conflict in Afghanistan for several years by jamming remote detonation devices such as garage door openers or cellular telephones. Two Prowler squadrons are also based in Iraq, working with the same mission.
