I'm not sure exactly when US Airfix came into being. I do know that prior and after, Airfix kits were repackaged by MPC. I'm sure someone knows, but it isn't I. Regardless, Airfix released this kit in 1978 and this one is dated 1980. Molded in white plastic (undoubtedly due to the scheme), it is fine raised panel lines with raised detail for the instrument panel and side consoles.

You are able to do either an F-15A or two seat F-15B, and to accomplish that, you are provided with different upper fuselage sections. As is standard with Airfix kit of the time, the seat is basically a shape onto which you place crew figures. There are control sticks for each of the tubs. If doing the A, then an electronics bay is in place of the rear seat.

The fuselage is split into upper and lower halves with the nose gear well molded in place. The interior bits are installed and the halves closed. Intakes are two piece and are fairly shallow. Before attaching the upper insert, you need to attach the rear cockpit section depending on which variant you are building. The nose cone is separate and while it don't think this needs nose weight, it would be wise to leave that off until the airframe is complete just to be sure.

Wings are upper and lower halves with the upper half containing the flaps and ailerons. Holes for the wing pylons are already opened up. Tailplanes are a single piece as are the fins. Note that the fins are of the production version, while this kit is of a preproduction prototype so should have both fin balances the same thickness. I've included a photo of this aircraft in this scheme. Note that the nose probe was not always carried, but the aircraft never got the production fin tip during its long life as a test plane.

The kit's landing gear is actually pretty nice, though the main wheels could use replacement as the hub detail is fairly shallow. You can leave the gear off until the airframe is painted if you so wish, but if doing the white scheme, it would be prudent to install the gear and doors as everything there save the wheels will be white. The kit also has a lowered boarding ladder, though it was not always seen when the plane was on the ground.

The final items include three fuel tanks;  two pylon and one centerline. Airfix provides weapons that include four Sparrow for the fuselage and Sidewinders for the wing pylons. You can also pose the canopy open or closed if you so wish. Note that rarely will one see the box art plane with weapons or even pylons so keep that in mind.

Instructions are well done and provide generic paint information. Markings are by Scalemaster and include not only the box art plane, but also the 49th FW boss bird in a standard early F-15 scheme. If you don't like the kit decal choices, there is no lack of early F-15A/B decal options out there.
