SUBJECT

In 1999 the Australian Department of Defence announced Project AIR 6000 "New Air Combat Capability (NACC)", which was intended to find a replacement for the air combat capability provided by both the 71 F/A-18A/B and 35 F-111C/G then in service.  The F/A-18 provided air combat, strike and close air support capabilities, while the F-111 provided long range strike, reconnaissance and maritime strike capabilities to the RAAF. AIR 6000 sought to find a single platform that was able to undertake all of these missions.

Expressions of interest were sought from major aircraft manufacturers in Europe and the US and an eventual 9 contenders were under consideration.  Alphabetically, these were:

  • Boeing F/A-18E/F Super Hornet
  • Boeing F-15E Strike Eagle
  • Dassault Rafale
  • Eurofighter Typhoon
  • Lockheed Martin F-16E/F Desert Falcon
  • Lockheed Martin F-22 Raptor
  • Lockheed Martin F-35 Lightning II
  • SAAB JAS-39 Gripen
  • Sukhoi Su-27/30/35 Flanker

In June 2002 Australia joined the Joint Strike Fighter (JSF) development program and announced that the Lockheed Martin F-35 would be the solution to AIR 6000, provided that the final design met the RAAF needs and budget.

In the mid 2000's I decided I would build all of these "AIR 6000" jets and this is the first one I've completed. It is my interpretation of what a RAAF Gripen might have looked like, had it been chosen instead of the F-35.

In my personal ranking, I put the Gripen as seventh out of the nine contenders:

  1. To be revealed
  2. To be revealed
  3. To be revealed
  4. Dassault Rafale
  5. To be revealed
  6. To be revealed
  7. SAAB JAS-39 Gripen
  8. To be revealed
  9. To be revealed

While it is a very capable aircraft, and reportedly cheap to operate, its small size limits its range.  With a major requirement being the defence of our northern approaches, range is a critical performance measure.  Australia is approximately the size of continental USA, with long distances between air bases, and the rest of the world is a long way away.

ADF aircraft are assigned a serial number starting with the prefix "A", then a type number followed by an individual aircraft number.  (For further information on this see Reference 1).   As the F-35 has been allocated the type number A35, I decided that the JAS-39 should be allocated A39, and, as I rank this aircraft as seventh, the full serial is A39-007.

79 SQN RAAF was established in 1943 with Spitfires for the defence of Australia against the Japanese, being deactivated in November 1945.  It was reactivated in 1962, operating CAC Sabres from Ubon Air Base in Thailand, before being deactivated again in 1968.  It was reactivated at RAAF Base Butterworth, Malaysia, in 1986 to operate Dassault Mirage IIIO while other squadrons transitioned to the F/A-18 Hornet, before being disbanded again in 1988.  Its final reactivation occurred in 1989 as a fast-jet transition squadron operating Aermacchi MB-326s.  It currently operates Hawk 127s.  Due to the squadron's history of repeated activation/deactivation, the squadron crest features a Phoenix. (Reference 2)

As the Gripen (Griffon) is also a mythical creature, I decided my Gripen should belong to 79 SQN.

CONSTRUCTION

This kit dates back to 2005 and I bought it on a trip to the UK in 2006.

The external shape of the kit is quite good - that is it looks like a Gripen - but the cockpit is overly simplistic and looks nothing like the real thing.  So, I purchased the CMK update set that brings it up to JAS-39C standard.  The set principally includes resin replacement for the cockpit and ejection seat, plus an inflight refueling probe, various antenna blades and piton tube plus a vacu-form canopy and photo-etch details.

I cut away the necessary cockpit parts to fit the update set and glued the fuselage halves together to see how they fitted.  I also glued the upper wing surfaces to the lower single piece to see how they fitted to the fuselage.

And that is where I left it for a decade or so...

In 2018 I decided that his would be my entry in my model club's annual "gunna build/gunna finish" competiton, but I didn't quite finish the kit for in time (98% complete).

There were only a few problem areas with the assembly of the kit.

  • While the wings and fuselage fit together nicely, the upper wing surfaces are a butt join with the fuselage sides.  To give some strength to this join, and to make sure there were no gaps, I glued two sprue spreader bars across the fuselage interior.
  • The intakes are separate parts that required blending into the fuselage with some super glue and sanding.  I added the update set F.O.D covers to the intakes prior to attaching them to the fuselage which hid the complete lack of intake trunks on the kit.
  • The canards have a press-fit pin into the fuselage and I managed to break one of these off doing a test fit.  As these are coupled together on the real aircraft, I decided to cut the pins off, drill them out and connect the canards using a length of metal rod.  Now they move up and down as one.
  • Although the update included a vacu-form canopy, I decided to use the kit parts.  The problem I had here was that I couldn't work out how the canopy attached to the fuselage in the open position.  This, combined with the fact that I lost a small chunk of the canopy sill when I cut it from the sprue, led me to decide to have the canopy closed. Fortunately, it is clear enough that you can see the detail inside.
  • The main undercarriage could use a locating pin to strengthen the join.  Even though I used super glue one of them collapsed while I was taking these photos.  Fortunately, I spotted it after taking a photo from behind, so I repaired it and re-took the photo.
  • The nose undercarriage doors have a vague fit.  I cut down the tabs on the doors so that the doors made contact with the fuselage to give a more secure attachment.  The forward door required two pneumatic arms to be attached between the door and the undercarriage leg, which was fiddly to do, and my main frustration with the kit.  I lost one of the arms while trying to attach it, so I replaced them with some hollow brass rod and a pin.  I wish these arms had been moulded as part of the leg itself. Also, it doesn't show in any of these pictures, but, looking from the front, the door is slightly off vertical.
  • The Gripen has a small fin mounted at an angle behind each of the canards.  The kit parts are far too big while the CMK upgrade set parts were a little too small, so I cut down and reshaped the kit parts.  I later cut down the CMK parts to make the angle-of-attack vanes on each side of the nose and the yaw vane under the nose.
  • I used the kit nose rather than use the CMK one, but replaced the piton with a pin.
  • I did use the CMK provided antenna on the fin leading edge but broke it off when handling the kit during painting, so I replaced it with a pin too.
  • I sanded off the formation strips and lights and replaced them with the etch and clear resin provide by CMK.
  • I relocated the horizontal blade antenna on the fin based on photos of JAS-39C.
  • In photos there is a fairing with a dark spot under the port wing root that is not present on the kit.  I replicated this with a shaped piece of sprue.

I decided I would arm my Gripen with Meteor and AIM-9X missiles plus GBU-53 small diameter bombs (SDB II).

Gripen is the first aircraft to fire a Meteor BVR missile and is the first type to go operational with the weapon (Reference 3).  I scratch built a pair of Meteors using the AMRAAMs from the Revell Eurofighter Typhoon and basing them on the Meteors from the same kit.

The photos at the bottom of Reference 5 show the Gripen armed with GBU-39 SDB I but I didn't have any of those available to me.  However, the Meng F-35A comes with the more capable GBU-53 SDB II as well as the BRU-61 bomb carriage system, which I used.

Lastly, I decided to put AIM-9Xs on the wingtips, which I sourced from the Kinetic F/A-18 kit.

Maestro Models produces a resin set of NATO outer pylons with BOP/B & MML rails with BOL for the JAS-39 Gripen.  The rear of the pylon includes the BOP/B with 6 circular flare/chaff slots and the MML rail has the BOL flare/chaff dispenser at the back.  I used these to mount the Meteors under the outer wing.

To round thing out, I mounted an AAQ-33 Sniper XR targeting pod on the pylon under the starboard intake.  This also came from the Kinetic F/A-18 kit.

PAINTING

As this is a what-if build I had no constraints on the colour scheme.

My original thoughts were to apply a four-greys scheme along the lines of the early SAAB Viggen multi-green camouflage.  I picked up a brochure from the SAAB stand at the Australian International Air Show one year that featured the JAS 39E/F proposal for the Danish Air Force with a paint scheme similar to the one I was thinking of.  Reference 4 has a picture of the Danish proposal.  But then I decided that would take too much effort to mask for painting, particularly as it would require the full pattern to be worked out and then cut in order to ensure that the scheme was consistent over all the aircraft surfaces.

So, I decided on a three colour, all over camouflage pattern with soft, freehand demarcations and began to map out schemes on my computer.  I decided to do a three-grey wrap around scheme but with darker colours dominating the top and the lighter grey dominating the under surfaces.

But, then I had another idea.  I would mask and paint a 'digital' camouflage version of my three-grey scheme - how hard could that be?

I first painted the aircraft the middle grey (FS 36231) and then sprayed slightly over large areas of the dark grey (FS 36118).  When dry, I masked the dark grey with large rectangles using 6 mm Tamiya tape, leaving a border of dark grey.  I then cut more tape into 2 mm x 2 mm squares and applied these around the masked areas to give a "digital" effect.  I then sprayed the light grey (FS 36375) areas and repeated the masking process over this colour.  The remaining unmasked areas were then resprayed the middle grey and masks removed.

I also painted a false canopy on the underside of the fuselage using Tamiya XF69 NATO Black, which is a very, very dark grey.

After I'd finished this scheme I found pictures of the proposed 'Sea Gripen' which had a strikingly similar camouflage, including the false canopy (Reference 5 and 6).

The national insignia and aircraft numbers were sourced from Aussie Decals sets while the formation strips and some of the stencils came from the kit decals.  Other stencils were sourced from the Kinetic F/A-18 kit, as were the AIM-9X decals.

The 79 Sqn low viz. squadron insignia was sourced from the Caracal Mirage decal set.  These featured a horizontal dark grey stripe with light grey pin stripes with a circular squadron badge inset.  However, the port side had a cut-out in the stripe to allow for the Mirage rudder control fairing.  Rather than try and paint match for this I decided to mask the background for the squadron insignia and then mask and spray on the stripes.  I then cut out the squadron insignia from the decal and applied that to the tail.

CONCLUSION

After an early start, this kit spent a long time on the shelf before I picked it up again and completed it.

I'm glad I got energised again and I'm very happy with the way it turned out, particularly the camouflage scheme.

I'm currently finishing off my second 'Air 6000 Jet', a Dassault Rafale B which has also spent a bit of time on the shelf waiting to be finished.  I'm going to make sure build the rest of the set before too long.
