1/72 Monogram EF-105F

Project Northscope

Under Project Northscope (Later Commando Nail), in approximately March of 1967 a small number of around 13 F-105F's that had originally been modified to Wild Weasel EF-105F's in 1966, were further upgraded with an improved/tweaked R-14A NASARR radar that allowed for sharper target definition on the rear-seaters radar scope and also provided for a limited early low-level terrain avoidance capability.  Additionally, the weapons release system was modified to allow the rear-seater to control bomb release and special lighting was added to both cockpits.  This was the USAF response to the success of the all weather/night attack capability that the Navy was enjoying with the A-6A Intruder starting in 1965.  Originally this had started for the USAF with F-105's flying sorties with EB-66 Destroyers that acted as pathfinders using the Destroyer's K-5 radar bombing navigation system to guide the Thuds to their target and then signalling them for bomb release.  It was then later realized that the Thud's own radar and bombing computer could be used in conjunction to achieve the same results and these aircraft would be sent out on low-level, night-time, single plane raids on targets deep within North Vietnam.  These aircraft were assigned to the 44th TFS at Korat Royal Thai Air Force Base and the crews (who had been specifically selected by PACAF Commander, General John Ryan), became known as "Ryan's Raiders."  To help camouflage the aircraft at night from below, they had their light gray undersurfaces overpainted with the upper surface tan and SAC Bomber Green.  Since these aircraft were still being used in both their original bombing and Wild Weasel rolls during the daytime, ground crews were hard-pressed to have them turned around and ready for their night-time raids as well.

Throughout the first Rolling Thunder bombing campaign, Northscope crews had flown around 415 sorties on a near nightly basis, but bomb damage assessment was limited, as many of the targets were also hit during daytime raids (sometimes on multiple attempts), so it was hard to gauge success of the concept since it was not known under which raids the damage was caused.  At least 3-4 of these aircraft were lost on these night-time raids and it would seem that overall it was not deemed as a huge success.  But through this program, tactics were developed for what was believed to be the impending deployment of the B-58 Hustler to Southeast Asia to do the same mission (which lead to the urban legend of a B-58 painted similarly to the B-52D camo at the time).  We now know that this was not to be, but what was learned was rolled over to the F-111A program and its first deployment to Southeast Asia in Project Combat Lancer/Harvest Reaper and the USAF finally had it's all-weather/night attack capability (even if it did go through it's own growing pains... but that's another story).

I utilized the excellent Monogram 1/72 F-105G Wild Weasel kit (which was a pretty trouble free build) and back-dated it to EF-105F standard by leaving off the ALQ-105 pods on the sides of the fuselage and removing the ALR-31 antennas on the wing-tips and the G-specific wing-tip lights that protrude from the front of the wing-tips.

The gun-gas purge vents on the right side of the nose were filled in as they do not appear in the reference photo I have of this aircraft.  I did not fill in the left side purge vents since the Thud fleet started receiving these right around the time that the Raiders were flying their missions, so I'm going to assume that they had them.  I also removed the scabbed on reinforcing plates on the top and bottom of the wings since this appears to be a post-Vietnam modification.  All other raised panel detail was sanded smooth and I only rescribed certain panels and antennas that would help with painting later.

The wing tanks, center-line MER with bombs and outer weapons pylons came from one of Revell's F-105D kits since Monogram did not include these with their G-kit.  The twin AIM-9B launch rails were scratch-built to match pictures of this set-up seen on Thuds and I went with the AIM-9B as part of the load-out, as fellow ARC forum member ThudDriver stated that he had seen in a report where the Ryan's Raiders crews used these to suppress North Vietnamese search lights at night, as they would apparently home in on the heat given off by the lights.  Seems like a pretty good use for this variant of the AIM-9 since I've heard that they were about as useless as a fire-cracker for much of anything air-air.  The AIM-9's and the ALQ-87 ECM pod came from Hasegawa weapons sets.

 

I've always found the wrap-around paint scheme and the use of SAC Bomber Green for the undersurface colors on these birds to be really intriguing and always wanted to build one of them, but information on specific aircraft and other details of this mission are fairly scarce and it wasn't until recently that I felt I had enough information to pick an aircraft to model.  I ended up deciding on aircraft 63-8353 that was known as "Whar's Dem Migs??" while it was flying the Raider mission.  It was lost over Route Pack 1 on July 15, 1968, with Major Gobel James ejecting to become a POW and Captain L.E. Martin being killed in action.  It was also known as "Billie Fern/Thunderchief" in service.  Not sure if it was still doing the Raiders mission at the time of its loss though... as it's been said that these aircraft were returned to their normal configuration by the end of 1967.

The camo pattern on this aircraft appeared to be a 'reverse' pattern similar to the standard Thud camo, except that it has the Medium Green and the Tan reversed in the pattern... although it's obvious in the right side photo of this aircraft that the pattern on the right side of the nose was decidedly non-standard... so I don't know about the rest of the aircraft, but the vertical stab looks to be standard and there were other Thuds that were done in this 'reverse' style pattern at the time, so I took a few liberties with the upper surface camo pattern.  The underside pattern is a complete guess considering the rarity of photos of these aircraft.  The fuel tanks and the wing pylons were splotched in Tan and SAC Bomber Green per a couple of profiles in two different references, but I have not seen photographic evidence to verify this though.

It took me a while to figure out the tail-number to match the art-work underneath the intakes, as I had a nost-art book that had a really excellent photo of the art-work, but did not identify the specific aircraft anymore than to say that it was a "Ryan's Raiders" aircraft (Some references just really leave a lot to be desired at times!)  One day while looking at a well-known photo of aircraft 353 I made a realization that there was art-work underneath the intake and it was pretty obvious (with the help of a magnifying glass) to see that it was the art-work for "Whar's Dem Migs??"

Seeing that these markings have never been done in 1/72 scale (that I'm aware of... but it was available for you 1/48 builders from Aeromaster a while back - but be cautious with Aeromasters camo painting guide, as the right side is definitely wrong in their instructions)... I scanned in the photo I had of the art-work and proceeded to color it in so that it didn't look so much like a photo when I lazer-printed it.  I also matched the surrounding colors as best as I could so that I could print this on white decal paper and try to blend in the paints with the decal as much as possible.  Not perfect by any means (as you'll be able to tell from the close-up I've included), but I wasn't left with much alternative.  I've also included this art-work on the left side of the aircraft as well, as I don't have any confirmation either way of whether it was carried there or not.

The white serial number and identification letters on the vertical stab were done with Woodland Scenics 45-degree Gothic dry transfer letters and numbers.  The black letters/numbers on the vertical stab and on the yellow radar reflector on the nose gear were done on my lazer printer.

Thud specific stencils came from several Thud decal sheets from several different manufacturers that I have in my stash.

Additional blade antennas made out of thin strips of Evergreen styrene were added to the underside of the fuselage behind the nose-gear bay and with that the kit was pretty much finished and adds another mighty Thud to my finished collection!

Respects to the Raiders crews as they truly had solid-brass cajones to fly these missions with the technology available to them at the time and were trail-blazers for the F-111 program that followed!
