SHOEHORN MOD. 1

The F-4Bs appearance was dramatically changed with the introduction of the new shoehorn equipment and the associated new fairings.  A new radome profile saw a hook shape fairing added to the lower portion of the chin fairing that replaced the production now unused cryogenic door intended for servicing the IR seeker equipment which was now removed. There were four canoe-shaped fairings located on the undersides of the aircraft with two under the intakes and another two just outboard of the speed brakes. A pair of new blade antennas were fitted onto the spine just aft of Door 19 behind the cockpits and an additional blade antenna was fitted just behind the nose gear bay.

 Doors 622L & 622R were the new chaff bay doors with one on each side of the upper fuselage just aft of the RAT bay's location. There were new fairing fin caps on top of the tail with a large rounded fairing on the leading edge and an oblong fairing on the trailing edge over the rudder's top line. To gain access to the new equipment in the tail's upper area saw the introduction of a larger Door 621 that replaced the original production Door 68 on the left side of the tail's upper area. A new Door 616 was added to the rear fuselage left side in front of the production standard Door 60 no doubt to give access to some new ' black boxes ' located in that area.
