AGM-45 Shrike Missiles for Tamjets A-4 Skyhawk and BVM F-100F Super Sabre (Wild Weasels)
The Shrike is an anti-radiation missile used against ground based threat radar installations. The Shrike was typically carried by the A-4 Skyhawk on either wing pylon and sometimes both when flying Iron Hand missions. The F-100F flew with the Shrike on either the outer or inner weapons pylons on either side of the wing tanks. The Shrike is a very striking missile with the oversized front fins and protrudes quite far beyond the leading edge of the wing giving the aircraft a very mean look.

Completed un-finished Shrike missile shown left. Take note of some of the actual measurements below for the fin/parts placements before beginning assembly. Some find it easier to sand and finish prime the tube seams before gluing the fins in place. You can still see the seems on the inside of the tubes for the fin placement.
The rear edge of the front fins are located 7.5" forward of the rear of the fiberglass missile body tube. The rear fins are located on the rear edge of the missile tube body. The rear mount ring just is located 1/4" forward of the rear fin's forward edge. Note the tab on the rear mount ring is facing to the left and is aligned with the top left rear fin. This is the left wing missile. The tab faces out as shown when on the left wing pylon. Note the band location between the front fin. There are 4 bands and they locate 1/2" forward of the rear edge on each front fin. Place the bands between each of the 4 fins along the same location. The rear bands (U-shaped) place between the rear fins with the band's rear edge aligned with the rear edges of the fins.
If you purchased an older set of Shrike missiles, you will find a fins position locator in the packaging. The ring has 4 slots ground into the diameter for locating the position of the 4 front and rear fins. The tab lines up with the seams on the missile body tube as shown to the left. Using the measurements above, mark the locations of all 8 fins on the main body tube. Once marked, carefully grind the fiberglass tube as shown along the length of the tube where the fins are to be placed.
Note: If you purchased a the newest set of Shrike missiles, the fiberglass missile body tube will have scribe lines for the placement of each fin.
Gluing Rear Fins in place
Glue each fin in place using medium CA. Spraying a small amount of kicker on the tube before placing the fins. This will allow rapid placement of all the fins. BE SURE THE FINS ARE PROPERLY ALIGNED BEFORE TOUCHING THEM TO THE KICKER as they will cure instantly when you do. Repeat for all 4 rear fins per missile.
Take note of where the blocks are inside the missile tube (this is the top surface). Write the word "TOP" on the top of missile tube just forward of the rear mount ring. Be sure to use pencil.
Glue each exhaust nozzle in place where shown to left. The back of the nozzle should line up with the rear edge of the missile tube.
Once all the rear fins have been glued onto each missile body, slide the rear mount rings in place onto the tubes with the tab shown on left.
NOTE: Remember one tab will point to the left and one to the right when viewed from the top. Note the tab lines up with the fin. Space the ring 1/4" forward of the front edge of each fin.
Place the rear spacer bands one at a time as shown to the left and glue in place using a drop of thin CA on each side where the spacer touches each fin. Repeat for all 4 rear spacers on each missile.
Glue the 4 front fins in place on each missile using the same method as the rear fins. Be sure the rear edge of the front fins is 7.5" forward of the rear edge of the missile tube.
Glue the 4 front fin spacers in place using a small drop of thin CA for each band. The bands are located 1/2" forward of the rear edge of each fin as shown to the left. This completes the missile assembly. The mounting holes for the missiles are as follows. For the BVM F-100, the holes are 4.25" and 8.25" forward of the rear edge of the missile tube. Use an 1/8" drill bit for the bolt thru hole and a dremel conical grinding tip to provide bolt head clearance holes on the 2 bottom bolt holes on each tube. The bolt hole measurements for the Tamjets A-4 Skyhawk are: 3.5" and 7.625" forward of the rear edge of the missile tube.
Once the missiles are assembled, run a fillet of 2hr epoxy around the base of each fin. finish off the base of each fin and any gaps between the fins and spacers using filler putty (bondo type) sand smooth and prime. The color schemes for Shrike missiles are typically all with with color bands (yellow, red, black or blue) around the missile body. The bands should be 1/4" wide and typically placed as shown below. There should also be an armament box (flat black) on the front outside center of the missile. See photo below for details.

AGM-12B Bullpup A Missile for Tamjets A-4 Skyhawk and BVM F-100D/F

F100 Firing Bullpup
Finished/assembled Bullpup shown. Rail shown for BVM F-100 only. Tamjets A-4 Skyhawk does not use this part.
You may finish the seams before starting the assembly process. Check the location on the mounting blocks on the inside of each tube as this denotes the top of the missile. Mark "top" on the top of the missile tube just in front of the rear of the missile to help remember.
Start assembly by gluing rear ring onto tube using a drop or two of thin CA where shown in photo to left.
Repeat for second missile.
Locate the 4 scribe lines on the missile tube and grind along the center of each scribe as shown to the left. There is a slight cross scribe for locating the rear edge of the rear fins, do not grind behind the cross scribe. Be sure to mark the front of the fins on the tubes and not to grind beyond the mark. Glue each rear fin onto the tube using medium CA. Apply CA to base edge of each fin. Use kicker to speed the curing. See fully assembled photo above.
Locate the scribe lines for the front fins. They will be for and aft of the small circles near the front of the missile. Do not glue the fins on yet. Slide the second ring onto the tube (see fully assembled missile photo). If missile is for F-100, place rail against rear ring as should in fully assembled photo. Glue rail in place centered between the rear fins and along the tubes length using thin CA. Sometimes the rails will try to curve slightly. Be sure to hold them straight and glue a drop at a time. One rail is in place, glue the front ring in place up against the front edge of the rail. Simply glue the front ring in place behind the front scribe line on the tube for the A-4. No rail is used. See fully assembled photo and glue ring in place where shown in photo as if rail was used and removed.
Glue front fins in place using med CA. Apply the glue to the base edge of each fin and then attach to tube. Use kicker to speed cure.
Glue exhaust nozzle in place using thick CA. Use a drop to hold the nozzle and then use kicker to tack in place. Once satisfied with position, glue all around the nozzle/tube with thick CA. Use kicker again to speed cure. Mounting bolt hole locations are as follows: BVM F-100, 4.25" and 8.25" forward of the rear edge of the missile tube. Use a 1/8" thru hole and a 3/16 hole on the bottom of each missile tube for bolt head clearance.
A-4 mounting holes are: 3.5" and 7.625" forward of the rear edge of the missile tube.
Color schemes for the Bullpup missiles ranged from solid blue (inert test) to all white with the mounting bands painted black or red to white with a blue center band and red stripe as shown below.
