Why carrier air wings moved away from dedicated strike aircraft

Why have navies moved away from dedicated strike aircraft such as the A-6 Intruder?

Multirole aircraft simplify carrier logistics and can deliver enough precision weapons for most missions, though peer warfare may revive specialized or optionally crewed strike platforms.

A carrier has fixed hangar, maintenance, spares, and personnel capacity, so one multirole type can produce more aggregate capability than several specialized fleets. Precision weapons also reduce the need to carry large numbers of bombs for each target, while the Super Hornet approaches the useful payload of older dedicated attackers. A peer conflict could revive a high-low mix in which dedicated fighters and strike aircraft each occupy part of the air wing. The panel suggests that any future specialist attacker may be uncrewed or optionally crewed, though dependence on vulnerable communications remains a constraint.
