The eight prototypes and pre-production Intruder aircraft were sometimes referred to with the ''YA-6A'' designation.<ref name=Jenkins_p100>Jenkins 2002, p. 100.</ref> These were used in the development and testing of the A-6A Intruder.

The initial version of the Intruder was built around the complex and advanced ''DIANE'' (Digital Integrated Attack/Navigation Equipment) suite, intended to provide a high degree of bombing accuracy even at night and in poor weather. DIANE consisted of multiple [[radar]] systems: the [[Norden Systems]] [[AN/APQ-92]] search radar replacing the YA-6A's AN/APQ-88, and a separate AN/APG-46 for tracking, the AN/APN-141 radar altimeter, and an AN/APN-122 [[Doppler radar|Doppler navigational radar]] to provide position updates to the Litton AN/ASN-31 [[inertial navigation system]]. An air-data computer and the AN/ASQ-61 ballistics computer integrated the radar information for the bombardier/navigator in the right-hand seat. [[TACAN]] and [[Automatic Direction Finder|ADF]] systems were also provided for navigation. When it worked, DIANE was perhaps the most capable navigation/attack system of its era, giving the Intruder the ability to fly and fight in even very poor conditions (particularly important over [[Vietnam]] and [[Thailand]] during the [[Vietnam War]]). It suffered numerous teething problems, and it was several years before its reliability was established.
