Why the F-4 Phantom did not simply adopt the AIM-54 Phoenix

Payload capacity was not enough: the Phoenix depended on radar, data, and fire-control systems around which the F-14 was purpose-built.

Question

Why was the AIM-54 Phoenix not adapted for the F-4 Phantom?

Short answer

The main doubt concerns the F-4's ability to support Phoenix's radar, data, and launch requirements; the F-14 was designed around them.

Notes

The Phantom's ability to carry heavy weapons does not by itself establish that it could operate Phoenix. The concern is whether it could provide the data support and associated systems needed to use the AIM-54. The Tomcat is described as having been designed around the missile's radar control and launch requirements. The example makes weapon integration a question of the complete aircraft system, beyond lifting the missile's weight.
