Why the US Navy did not replace the A-6 with another dedicated strike aircraft

Why has the US Navy not developed a new dedicated strike aircraft for mass missile salvos?

Its strike mission is divided among F-35 sensors, Super Hornet weapon loads, ship-launched missiles, and Air Force support, while the dedicated A-12 program was cancelled.

The panel treats the F-35 as the Navy's technical new strike aircraft while recalling the cancelled A-12 Avenger II as the intended Intruder replacement. Deep targets can draw on Air Force bombers, while targets within fleet range can be attacked from vertical-launch cells. A high-low air-wing concept lets stealthy F-35s find and designate targets before Super Hornets deliver a heavier missile load from safer range. The missing dedicated strike aircraft is therefore partly a consequence of distributed sensors and weapons rather than a complete loss of strike capacity.
