Well, on what the A-6E could do (part of a whole article):

I was in two Intruder squadrons during my time in the Navy: VA-34 and VA-75.

A tough and versatile aircraft, the A-6 was called upon to fly the most difficult missions. Its forte was to fly low and alone-in any weather. The all-weather attack jet has seen action in every conflict the US has been involved in since Vietnam. With the ability to carry more ordnance, launch a wider variety of space-age smart weapons, conduct day or night strikes over greater distances on internal fuel than any carrier borne aircraft before or since, and provide mid-air refueling support to other carrier jets, the Intruder represents the most versatile military aircraft in modern times.

The A-6E proved that it was the best all-weather precision bomber in the world in the joint strike on Libyan terrorist-related targets in 1986. With Air Force FB-111s, A-6E Intruders penetrated the sophisticated Libyan air defense systems, which had been alerted by the high level of diplomatic tension and by rumors of impending attacks. Evading over 100 guided missiles, the strike force flew at low levels in complete darkness, and accurately delivered laser-guided and other ordnance on target.
