Some background:
The BAC Jet Provost was a British jet trainer aircraft that was in use with the Royal Air Force (RAF) from 1955 to 1993. It was originally developed by Hunting Percival from the earlier piston engine-powered Percival Provost basic trainer, and later produced by the British Aircraft Corporation (BAC). In addition to the multiple RAF orders, the Jet Provost, sometimes with light armament, was exported to many air forces worldwide. The design was also further developed into a more heavily armed ground attack variant under the name BAC Strikemaster, which was not operated by the Royal Air Force but became a worldwide export success.
The Jet Provost was produced for the Royal Air Force in several variants with gradually stronger engines and other detail improvements, the first trainers entered RAF service in 1955. A major development step was the T.5 variant in 1967 with a pressurized cabin, a modified front section and the option for export customers to arm it with machine guns and underwing hardpoints. The T.5 was fitted with the Viper 201 or 202 turbojet engine and its versatility encouraged the RAF to utilize the Jet Provost in more roles besides basic training. With a top speed of 440 mph, excellent maneuverability, mechanical reliability and low operating costs, the Jet Provost was utilized as an aerobatic aircraft, for air warfare and tactical weapons training as well as for advanced training. T.5 deliveries from BAC's Warton factory commenced on 3 September 1969, and operators of the type included the RAFs Central Flying School and No. 1, No. 3, and No. 6 Flying Training Schools. During their career the T.5s were modified with improved avionics and a rough coating on the wing to break up the smooth airflow and give the trainee pilot an early indication of the onset of a stall (the T.5's original clean wing gave the pilot little warning); upgraded aircraft were re- designated T.5A. A sub-variant, unofficially designated T.5B, was a small number of T.5As fitted with wingtip-tanks (so far only used by export customers) and special equipment for long-range low-level navigator training.
During the Mid-Eighties the RAF started to look for a more economical successor for the aging Jet Provost fleet, and this eventually became the turbo-prop Shorts Tucano. The Tucano was selected in 1985 in preference to the Swiss Pilatus PC-9 and the British Hunting Firecracker. The first Tucano flew in Brazil on 14 February 1986, with the first Shorts built production aircraft flying on 30 December 1986. However, problems with the ejection seats delayed the introduction of the aircraft into service until 1989. During this period the Jet Provost remained the RAF’s mainstay trainer, but it was gradually withdrawn from RAF service, mostly due to many airframes’ age. However, late in their career a handful of these robust aircraft eventually saw frontline use and were deployed in a hot conflict during the first Gulf War, in an unexpected but important role that paved the way for new air strike tactics.
When the RAF took part in combat operations during Operation Granby/Desert Storm in 1991, it had been anticipated that complex and fast attack aircraft like the Tornado would autonomously perform air strikes, either with iron bombs against area targets or with precision weapons like laser-guided glide bombs against important or small objects. However, early experience from the front lines showed that deploying precision weapons was not easy: target acquisition and then both target designation and weapon deployment were not feasible with just a single aircraft – it would be exposed to potential enemy fire for too long or require two or more passes over the target, so that any surprise moment was ruined. During the early stages of the RAF’s air raids a strike group of six aircraft would require two of them to act as dedicated target designators, selecting and illuminating targets with laser projectors for other aircraft. Another problem was that these scouts had to fly ahead of the strike force, check out the battlefield and loiter at relatively slow speed in hostile environment until the fast strike aircraft would arrive and drop their weapons. “Wasting” Tornados and their strike capability for these FAC duties was regarded as inefficient, and an alternative aircraft that was better suited for this task was chosen: the vintage but small and nimble Jet Provost T.5A!
Early on, this had been thought to be "unlikely”, but following a short-notice decision to deploy, the first batch of six aircraft were readied to deploy in under 72 hours. These were dedicated long-range navigational trainers, operated by 79(R) Squadron as part of No. 229 Operational Conversion Unit, and the aircraft were hastily prepared for their unusual mission. This included the removal of the aerodynamic wing coating to improve the flight characteristics again, the adoption of desert camouflage, mounting of underwing hardpoints and additional equipment like an encrypted radio with better range and navigation systems (including a GPS sensor in a spinal fairing). As protective measures, Kevlar mats were added to the cockpit floor and lower side walls, as well as a passive radar warning system with sensors on nose and fin and chaff/flare dispensers under the rear fuselage. A fixed refueling probe was considered for the transfer flight and to extend loiter time during missions via air-to-air refueling, but this was not realized due to the lack of time.
To mark their special status the machines were (now officially) designated T(R).5B. They departed from RAF Brawdy in Wales for the Middle Eastern theatre early on 26 January 1991. Upon arrival the machines were immediately thrown into action. It now became common for each attack formation to comprise four Tornados or Jaguars and two Jet Provosts; each Jet Provost carried a 144-inch-long (3.66 m), 420-lb (209 kg) AN/AVQ-23E ‘Pave Spike’ laser designator pod on one of the outer underwing stations and acted as backup to the other in the event of an equipment malfunction. The machines would typically not carry offensive loads, except for occasional unguided SNEB missiles to visually mark potential targets, since they did not have a sufficient load-carrying capacity, but they were frequently equipped with drop tanks to extend their range and loiter time, and “Dash 10” (AN/ALQ-101) ECM pods to counter radar-guided weapons against them.
The first combat mission already took place on 2 February 1991, operating at a medium altitude of roughly 18,000 feet (5,500 m), and successfully attacked the As Suwaira Road Bridge. Operations continued, practically every available day, even though missions did not take place at night as the RAF’s ’Pave Spike’ pods (a simplified version of the American AN/ASQ-153) lacked night-time functionality. After the first missions the Jet Provosts received black anti-glare-panels in front of the windscreen – they had been re-painted in the UK without them, and the black panel markedly reduced the camouflage’s efficiency, but the strong and constant sunshine reflection from the Jet Provosts’ bulged nose frequently blinded the crews. Another retrofitted feature was the addition of a video camera to document the targeting missions, which was mounted in a shallow blister on top of the nose, just above the landing light cluster.
When the tactical separation of target designation and strike missions proved to be successful, more and more potent aircraft were sent into the theatre of operations, namely the RAF’s Blackburn Buccaneer, which replaced the Jet Provosts on long-range missions and also carried out strike and dive-bombing missions. Approximately 20 road bridges were destroyed with the help of the target spotter aircraft, restricting the Iraqi Army's mobility and communications. In conjunction with the advance of Coalition ground forces into Iraq, the Buccaneers switched to airfield bombing missions, targeting bunkers, runways, and any aircraft sighted on the ground, while the Jet Provosts were used over less dangerous terrain and closer to the air bases, primarily acting as artillery spotters. However, the designator pods were still carried to mark targets of opportunity and strike aircraft were then called in to eliminate them.
The Jet Provost T(R).5Bs took part in 186 missions during the Gulf War. Two from the total of eight deployed Jet Provosts were lost during their short active career: One was shot down at low level by a MANPADS (probably an IR-guided 9K38 Igla/SA-18 Grouse), both crew members were lost; the other crashed due a failure of the hydraulic system but could be brought down over friendly terrain and the crew ejected safely.
After their return to Great Britain the worn machines were quickly phased out and all T(R).5Bs were retired when 79(R) Squadron was disbanded in August 1992. The last Jet Provosts in RAF service were retired in 1993.

The kit and its assembly:
This fictional Gulf War participant was a spontaneous decision to build – actually as a group build submission, but it turned out to be ineligible. After fellow user SPINNERS posted one of his CG skins, a grey RAF low-viz Jet Provost at whatifmodellers.com, I suggested in the respective thread a machine in Desert Pink – and it was promptly realized, including equipment from the Gulf War Buccaneers and LGBs as ordnance. Inspiration enough to dig out an Airfix kit out of The Stash™ for which I had no concrete plan yet and turn the CG rendition into hardware.
The kit is a simple affair and shows its age through (light) flash and shaggy fit around the seams almost everywhere. Nothing dramatic, but you have to invest time and PSR effort. And it features the most complicated landing light arrangement I have ever come across: five(!) single parts if you include the front cover. Why the mold designer did not just provide a single clear piece with three lens-shaped dents at the back - and instead went for a bulkhead, three(!) separate and tiny clear lenses PLUS a clear cover that is supposed to fit in a rather dysmorphic nose opening is beyond me?
The kit was basically built OOB, using the Jet Provost T.5 air intakes and fuselage details but the Strikemaster wing tip tanks and wing pylons. The Pave Spike pod came from a Hasegawa 1:72 aircraft weapon set, the ECM pod from a Revell 1:72 F-16A (the vintage kit of the prototype with the extra engine) – it is shorter than a typical AN/ALQ-101, rather looks like an AN/ALQ-119, but these pods were all modular and could have different lengths/sizes. And I think that the shorter variant suits the Jet provost well, the Pave Spike pod is already quite long for the small aircraft.
Unlike SPINNERS I settled just for drop tanks on the inner wing stations to extend range and loiter time. I also doubt that the Jet Provost had enough carrying capacity and speed for LGBs, and on their target designation missions the RAF Buccaneers did AFAIK not carry much offensive ordnance, either. There’s also not much clearance under a Jet Provost on the ground – I doubt that anything with big fins could safely go under it? However, for a modernized look I replaced the Jet Provost’s OOB teardrop-shaped tanks with cigar-shaped alternatives.
Further mods were only of cosmetic nature: the seats received ejection handles made from thin wire, the characteristic chines under the nose were omitted (the kit’s parts are rather robust, and they were left away on some T.5s in real life, anyway), and I scratched small conformal chaff/flare dispensers from styrene profile and put them under the lower rear fuselage. Fairings for a radar-warning system were scratched from 1.5 mm styrene rods, too, some blade antennae were added around the hull, and sprue material was used to create the GPS antenna “bubble” behind the cockpit. The shallow camera bulge on the nose was created in a similar fashion.
Another problem: the model is seriously tail-heavy. I filled the chamber between the odd landing lights compartment and the cockpit with lead beads, but once the landing gear had been attached the model still sat on its tail. I was lucky that I had not glued the seats into place yet, so I was able to add more ballast in front of the main wheels, therewith creating a bulkhead (which is missing OOB) behind the seats, what was eventually enough to shift the model’s center of gravity forward.
Painting and markings:
Desert Pink was the driving theme for this build (to be correct, it’s FS 30279 “Desert Sand”). While real RAF aircraft from Operation Granby were painted all-over with this tone (and SPINNERS did the same with the CG rendition), I wanted a bit more variety and just painted the upper surfaces and the underside of the leading edges, the inside of the air intakes and the tip tanks in the sand tone, while the undersides were painted in RAF Barley Grey (Humbrol 167), as if an late all-grey low-viz trainer had been painted over just on the upper surfaces.
For the Desert Pink I was able to use the authentic tone, I had a virgin tin of Humbrol 250 in my enamels hoard that now found a good use. After basic painting the kit received an overall black in washing, dry-brushing with Revell 35 (Skin – it’s a perfect match for panel post-shading!) to retain the pinkish hue and, after the decals had been applied, a bit of grinded graphite to simulate wear and dirt and emphasize the raised surface details.
The cockpit interior was painted in Anthracite (Revell 06), the dashboard became medium grey with dark instruments (not painted, thanks to the raised details I simple rubbed some graphite over it, and the effect is nice!). The ejection seats became tar black with grey-green cushions. The landing gear was painted in Medium Sea Grey (Humbrol 165).
The drop tanks became Medium Sea Grey (Humbrol 165) and Barley Grey, as if they had been procured from a different aircraft, while the Pave Spike pod and the ECM pod were both in RAF Dark Green (Humbrol 163), for good contrast to the rest of the model.
Decals/markings come from Xtradecal sheets. The low-viz roundels were taken from a dedicated RAF roundel sheet because I wanted a uniform roundel size (in six positions) and slightly darker print colors. Unit markings and tactical codes came from a Jet Provost/Strikemaster sheet, also from Xtradecal; RAF 79 Squadron actually operated the Jet provost, but AFAIK only the T.4 version, but not the pressurized T.5 or even the T.5A navigator trainers. The nose art at bow side came from a USN EA-6B Prowler.
After some final details (position lights), the model was sealed with matt acrylic varnish.
A quick project, and the Operation Granby Jet Provost looks better than expected. However, I am not sold on the vintage Airfix kit. It clearly shows its age, nothing really went together smoothly, gaps and sinkholes, PSR on every seam. It also required tons of nose weight to keep it on its spindly legs. The alternative Matchbox kit is not much better, though, with even more simple surface and cockpit details, but at least the parts fit together. I might try to hunt down a Sword kit if I should want to build one again, AFAIK the only other IP option? The result looks interesting, though, quite purposeful with its low-viz markings, and the simple livery turns out to be very effective over the desert terrain where it would have been supposed to operate. Furthermore, the model fits well into the Jet Provost’s historic final years of duty with the RAF – even though in an unlikely role!
