An [[electronic warfare]] (EW)/[[Electronic countermeasures]] (ECW) version of the Intruder was developed early in the aircraft's life for the [[United States Marine Corps|USMC]], which needed a new ECM platform to replace its elderly [[Douglas F3D Skyknight|F3D-2Q Skyknights]]. An EW version of the Intruder, initially designated ''A2F-1H'' (rather than A2F-1Q, as "Q" was being split to relegate it to passive electronic warfare and "H" to active) and subsequently redesignated ''EA-6A'', first flew on 26 April 1963. It had a [[Bunker Ramo Corporation|Bunker-Ramo]] AN/ALQ-86 ECM suite, with most electronics contained on the walnut-shaped pod atop the vertical fin. They were equipped with AN/APQ-129 fire control radar, and theoretically capable of firing the [[AGM-45 Shrike]] [[anti-radiation missile]], although they were apparently not used in that role. The navigational radar is AN/APN-153.

Only 28 EA-6As were built (two prototypes, 15 new-build, and 11 conversions from A-6As), serving with U.S. Marine Corps squadrons in [[Vietnam War|Vietnam]]. It was phased out of front line service in the mid-1970s, remaining in use in reserve VMCJ units with the USMC and then the United States Navy in specialized VAQ units, primarily for training purposes. The last EA-6A had been retired by 1993.

A much more highly specialized derivative of the Intruder was the [[Northrop Grumman EA-6B Prowler|EA-6B Prowler]], having a "stretched" airframe with two additional systems operators, and more comprehensive systems for the electronic warfare and [[SEAD]] roles. A derivative of AN/APQ-156, AN/APS-130 was installed as the main radar for EA-6B. The navigational radar was upgraded to AN/APS-133 from the AN/APN-153 on EA-6A. In total, 170 were produced. The EA-6B took on the duties of the U.S. Air Force [[General Dynamics–Grumman EF-111A Raven|EF-111 Raven]] when the DoD decided to let the U.S. Navy handle all electronic warfare missions. The Prowler has been replaced by the [[Boeing EA-18G Growler|EA-18G Growler]] in the U.S. Navy and was retired from USMC service in 2019.
