Its primary function for much of its later service life was as an electronic warfare platform, tactical air reconnaissance platform, and high capacity aerial refueling tanker.

A modified derivative also served in the U.S. Air Force as a tactical until the early 1970s as the B-66 Destroyer, to include EB-66 electronic warfare and RB-66 reconnaissance versions. The Skywarrior is one of only two Navy attack aircraft intended as a strategic bomber to enter service.

, the Navy began to explore the concept of a jet-powered aircraft operating from aircraft carriers. Success encouraged further development of the concept, and early in the post war years the Navy began to consider jet power as a possible means of operating carrier-based aircraft that were large enough to provide a strategic bombing capability.

, later to win fame for the A-4 Skyhawk, fearing that the United States-class was vulnerable to cancellation, proposed a significantly smaller aircraft of 68,000 lb (31,000 kg) loaded weight, capable of operating from existing carriers. The contract which the Navy awarded to the Douglas Aircraft Company on 29 September 1949 led to the development and production of the A3D Skywarrior. The prototype XA3D-1 first flew on 28 October 1952.

Considerable development problems, largely with the original engines, delayed the introduction of the Skywarrior until spring 1956. The A-3 was, by far, the largest and heaviest aircraft ever designed for routine use on an aircraft carrier, though ironically it was the smallest proposal among other proposals which could only be deployed on even larger carriers not yet in service. Because of its cumbersome size, and less-than-slender profile, it was nicknamed "The Whale" (after it converted to the electronic warfare

 fuselage, with the engines in underwing nacelles. Flight controls were hydraulic, and for storage below deck, the A-3's wings folded outboard of the engines, lying almost flat, and its vertical stabilizer was hinged to starboard.. Capacious internal fuel tanks provided long range.
The early A-3 variants had a crew of three: pilot, bombardier/navigator (BN) and crewman/navigator (aka: third crewman). An unusual cockpit configuration was incorporated with the three crew sitting under a framed canopy. In the raised compartment, the pilot and bombardier/navigator sat in a side-by-side arrangement with the pilot's station on port side having full flight controls. On initial variants, a third crew member, who also acted as a gunner for the twin tail-mounted 20mm cannons that equipped early versions of the A3D/A-3B, sat behind the duo in an aft-facing seat. The third crewman station had the sextant for celestial navigation and the defensive electronic counter measures equipment. Later electronic counter-measures variants could accommodate a crew of seven with flight crew consisting of a pilot, co-pilot and navigator plus four electronic systems operators occupying stations in the former bomb bay in the sumptuous fuselage.

Efforts to reduce weight had led to the deletion of ejection seats during the design process for the Skywarrior, based on the assumption that most flights would be at high altitude. A similar arrangement with an escape tunnel had been used on the F3D Skyknight. Aircrews began joking morbidly that "A3D" stood for "All Three Dead" (in 1973, the widow of a Skywarrior crewman killed over Vietnam

 sued the McDonnell Douglas Aircraft Company for not providing ejection seats in the A-3). In contrast, the USAF B-66 Destroyer was equipped with ejection seats throughout its service life.

Documented history of mechanical failures in the A3D / A-3 showed a rate well above average. While there were magazine articles that conjectured that the safety problem was compounded by assigning weaker pilots to slower jets like the A-3, during their heyday, Skywarrior pilots were often "best-of-the-best" due to its critical nuclear strike mission role.

The wing at NAS Whidbey Island would later transition to the EA-3 variant, eventually forming the nucleus for the Navy's Grumman EA-6B Prowler community, while the wing at NAS Sanford would convert to the A3J Vigilante in the nuclear heavy attack mission, followed by conversion to the RA-5C and transition to the reconnaissance attack mission. The Vigilante wing would also continue to retain a small number of TA-3B aircraft for training Naval Flight Officer

s in the Vigilante's radar and navigation systems. The Skywarrior's strategic bombing role faded quickly after 1960, briefly replaced by the A3J Vigilante, (later redesignated as the A-5A Vigilante) until 1964. Soon after that, the Navy abandoned the concept of carrier-based strategic nuclear weaponry with the success of the Polaris missile-equipped Fleet Ballistic Missile (FBM) submarine program and all A-5As were converted to the RA-5C Vigilante reconnaissance variant.

Vietnam

Skywarriors saw some use in the conventional bombing and mine-laying role during the Vietnam War from 1965 through 1967. The Navy would soon use only more nimble fighter sized attack bombers over Vietnam, but the A-3 found subsequent service in the tanker, photographic reconnaissance

 roles. Equipped with a drogue refueling hose and basket that was compatible with the "probe and drogue" refueling systems of all U.S. Navy, U.S. Marine Corps and some U.S. Air Force tactical jets, the Skywarrior would not only extend the range of a strike force, but save returning pilots short on fuel, much like the larger and more well known USAF Boeing KC-135 Stratotanker.

In addition, a version of the A-3B was modified into the RA-3B and used in Vietnam as a photo reconnaissance aircraft. Heavy Photographic Squadron 61 (VAP-61) at NAS Agana, Guam and sister squadron VAP-62 at NAS Jacksonville, Florida furnished crews and flew out of Da Nang AB performing mapping and intelligence gathering flight over the Southeast Asia area. With 12 camera stations the RA-3B was well equipped to perform cartographic mapping of areas where no detail maps existed.

Tanker role

During Vietnam, the Skywarrior was modified into a multimission tanker variant, the EKA-3B, that was a real workhorse for the carrier air wing. A-3 attack aircraft were modified to KA-3B tankers. Electronic jamming equipment was added without removing tanker capability so the EKA-3B could jam enemy RADAR while waiting to refuel tactical aircraft. Buddy tanking

 using A-4 Skyhawks and A-7 Corsair IIs, and inflight refueling using A-3 Skywarriors was utilized by the U.S. Navy in the Vietnam theater of operations from at least 1966 through 1973. Eventually, the EKA-3B was replaced by the smaller dedicated Grumman KA-6D Intruder tanker, which although it had less capacity and endurance, were more numerous in number with each carrier's air wing. Two additional Naval Reserve units were established in the early 1970s as air refueling squadrons, VAK-208 and VAK-308, at NAS Alameda, California. Both units operated aircraft with electronic warfare equipment removed and were redesignated as KA-3Bs. VAK-208 and VAK-308 were decommissioned in the early 1990s.

Cold War

The EA-3 variant was an indispensable resource for the Fleet Commander and was used in critical ELINT role operating from aircraft carrier decks and ashore supplementing the larger Lockheed EP-3. Its last service was as an ELINT platform during Desert Storm.

Spy plane

The EA-3B model was modified for electronic intelligence against the Warsaw Pact. Missions were flown around the globe beginning in 1956, with the U.S. Air Force EB-47 Stratojet flying a similar mission. The EA-3B carried a crew of seven, with flight crew of three in the cockpit and an Electronic Warfare Officer and three electronic systems operators/evaluators in the converted weapons bay. It offered unique electronic reconnaissance capabilities in numerous Cold War-era conflicts and the Vietnam War.

Retirement

EA-3Bs survived long enough to participate in the first Gulf War in 1991, although the Skywarrior was out of Navy service by September 1991. For more than three decades, the 282 Skywarriors the Navy procured served effectively in many roles with the last USN Skywarriors retiring on 27 September 1991.

Post-retirement career

In an agreement Hughes Aircraft had with the U.S. Navy, the Navy agreed to retain at least one A-3 aircraft in inviolate storage at Davis-Monthan AFB for long term support for major structural parts. Westinghouse also operated an A-3 in a similar arrangement.

The NAVAIR Weapons System Manager, who participated in the drafting of the contract, saw that support as no longer possible and Hughes was contacted to meet with Westinghouse and Raytheon

 to finalize plans for the support shutdown of the aircraft. At the last Integrated Logistics meeting at NAS Alameda, California, both Raytheon and Hughes indicated their willingness to obtain fleet A-3 Skywarrior assets instead of sending them to Davis-Monthan AFB, Arizona, thereby saving the airframes from destruction and saving the Navy the cost of storage at AMARC

.

As the plan matured, two other contractors, Thunderbird Aviation and CTAS also elected to participate in similar agreements. The fleet spares from ASO were distributed between the contractors evenly, and warehouses were emptied all over the United States. Unfortunately, due to misunderstandings and reorganizations within the Navy, the world wide ASO assets were scrapped, not getting to the contractors. In early 1993, CTAS decided that they no longer had use for their aircraft, and Hughes had several programs needing additional assets.

In early 1994, a USAF program decided to modify an A-3 for F-15 radar tests, and the only available airframe was stored at NAS Alameda since the fleet shutdown. Hughes added that aircraft to the bailment, and ferried the aircraft to Van Nuys for modifications. An entire nose section was removed from a stricken F-15B at AMARC at Davis-Monthan AFB, Arizona and grafted onto the front of the aircraft. Racks and equipment were installed in the cabin, and the aircraft is utilized by Hughes and the USAF for F-15 software development.

In 1994, Westinghouse decided to terminate their agreement with the Navy, and Thunderbird added their aircraft to the Thunderbird bailment. In 1996, Thunderbird Aviation went into receivership, and Hughes, through mutual cost savings to the Government, added the Thunderbird assets to the contract, prepping them for ferry at Deer Valley airport, and relocating them to Mojave, California

There was no equipment position for a second Electronic Countermeasures Officer or enlisted crewman in the converted weapon bay. The "jumpseat" was used for qualified instructor ECMOs training new ECMOs, for guest observers on operational flights, or for passengers during operational deployment transits. While the ERA-3B could withstand the stresses of a cable arrested landing, the ALT-40 and ALR-75 equipment in the former bomb bay was not stressed to withstand a catapult launch and the ERA-3B was never deployed aboard carriers.
