Some time ago I did a model of a Vigilante in RAAF Colours (posted on the Aero-space models board) - repeated here as a Recce bird:

At the time, someone (might have been GTX) suggested a Vigilante as a missile carrier, so why not!
The AA-5C Vigilante Archer:

Now I got carried away and put a Infra-Red Search and Tracking sensor on the upper surface above the Radar Intercept Officers (in place of the Nav) Cockpit, with the thought that this would not be retractable like on the F-106 but would be jettisoned as part of the ejection sequence. As the background story (in my mind) had Archer's developed because of problems with the F-14 Tomcat, I put the Camera/IRST from a Tomcat under the nose!

So, I guess the Archer has dual ISRT's, one searching above and one below. On the upper surface centered between the wings is a fairing that the USN has never really explained. Most believe it covers a SATCOM antenna, allowing the Archer to transmit data from the sensors back to the carrier or to receive additional data from the carrier. While the antenna of the AN/APG-71 is not as large as the proposed F-14 version, the Avionics for the radar are located in the centre of the internal weapons bay, along with the avionics to allow sensor fusion and processing.

There are also two small fairings on the side of the fuselage (on each side) that are unexplained, but as there is a small opening at the front of each, they are thought to be air intakes to provide cooling for the avionics bay.
The Archer carries (as shown here) a maximum load of 2 AGM-54 Phoenix and 8 AAMRAAMs.

One issue with this loading is that the aircraft cannot land back on the carrier with the second (rear) Phoenix on-board, as the rear surfaces foul the Archer's Tailhook. The Navy is believed to be developing a modified Phoenix with folding rear surfaces that would "spring" into position when the weapon is launched to overcome this issue.
