Some background:
The Rolls-Royce Griffon engine was designed in answer to Royal Navy specifications for an engine capable of generating good power at low altitudes. Concepts for adapting the Spitfire to take the new engine had begun as far back as October 1939; Joseph Smith felt that "The good big 'un will eventually beat the good little 'un." and Ernest Hives of Rolls-Royce thought that the Griffon would be "a second power string for the Spitfire". The first of the Griffon-engined Spitfires flew on 27 November 1941. Although the Griffon-powered Spitfires were never produced in the large numbers of the Merlin-engined variants they were an important part of the Spitfire family, and in their later versions kept the Spitfire at the forefront of piston-engined fighter development. The first Griffon-powered Spitfires suffered from poor high- altitude performance due to having only a single stage supercharged engine. By 1943, Rolls-Royce engineers had developed a new Griffon engine, the 61 series, with a two-stage supercharger. In the end it was a slightly modified engine, the 65 series, which was used in the Mk. XIV, the first Spitfire mark with a Griffon engine to enter service. The resulting aircraft provided a substantial performance increase over the Mk IX. Although initially based on the Mk VIII airframe, common improvements made in aircraft produced later included the cut-back fuselage and tear-drop canopies, and the E-Type wing with improved armament.
The Mk. XIV differed from its direct predecessor, the Mk XII, in that the longer, two-stage supercharged Griffon 65, producing 2,050 hp (1,528 kW), was mounted 10 inches (25.4 cm) further forward. The top section of the engine bulkhead was angled forward, creating a distinctive change of angle to the upper cowling's rear edge. A new five-bladed Rotol propeller of 10 ft 5 in (3.18 m) in diameter was used. The "fishtail" design of ejector exhaust stub gave way to ones of circular section. The increased cooling requirements of the Griffon engine meant that all radiators were much bigger, and the underwing housings were deeper than previous versions. The cowling fasteners were new, flush fitting "Amal" type and there were more of them. The oil tank (which had been moved from the lower cowling location of the Merlin engine variants to forward of the fuselage fuel tanks) was increased in capacity from 6 to 10 gal.
To help balance the new engine, the radio equipment was moved further back in the rear fuselage and the access hatch was moved from the left fuselage side to the right. Better VHF radio equipment allowed for the aerial mast to be removed and replaced by a "whip" aerial further aft on the fuselage spine. Because the longer nose and the increased slipstream of the big five-bladed propeller a new tail unit with a taller, broader fin and a rudder of increased area was adopted.
When the new fighter entered service with 610 Squadron in December 1943 it was a leap forward in the evolution of the Spitfire. The Mk. XIV could climb to 20,000 ft (6,100 m) in just over five minutes and its top speed, which was achieved at 25,400 ft (7,700 m), was 446 mph (718 km/h). In operational service many pilots initially found that the new fighter could be difficult to handle, particularly if they were used to earlier Spitfire marks. But in spite of the difficulties, pilots appreciated the performance increases.
F Mk. XIVs had a total of 109.5 gal of fuel consisting of 84 gal in two main tanks and a 12.5 imp gal fuel tank in each leading-edge wing tank; other 30, 45, 50 or 90 gal drop tanks could be carried. The fighter's maximum range was just a little over 460 miles (740 km) on internal fuel, since the new Griffon engine consumed much more fuel per hour than the original Merlin engine of earlier variants. By late 1944, Spitfire XIVs were fitted with an extra 33 gal in a rear fuselage fuel tank, extending the fighter's range to about 850 miles (1,370 km) on internal fuel and a 90 gal drop tank. Mk. XIVs with "tear-drop" canopies had 64 gal. As a result, F and FR Mk. XIVs had a range that was increased to over 610 miles (980 km), or 960 miles (1,540 km) with a 90 gal drop tank. The armament initially consisted of two 20 mm Hispano cannon and four light 0.303” machine guns (in a standard “C” wing configuration), but later builds had the latter replaced with a pair of heavier 0.5” machine guns that had better range and weight of fire (“E” wing configuration).
The first test of the aircraft was in intercepting V1 flying bombs and the Mk. XIV was the most successful of all Spitfire marks in this role. When 150 octane fuel was introduced in mid-1944 the "boost" of the Griffon engine was able to be increased to +25 lbs (80.7"), allowing the top speed to be increased by about 30 mph (26 kn; 48 km/h) to 400 mph (350 kn; 640 km/h) at 2,000 ft (610 m).
The Mk. XIV was used by the 2nd Tactical Air Force as their main high-altitude air superiority fighter in northern Europe with six squadrons operational by December 1944.
One problem which did arise in service was localized skin wrinkling on the wings and fuselage at load attachment points; although Supermarine advised that the Mk. XIVs had not been seriously weakened, nor were they on the point of failure, the RAF issued instructions in early 1945 that all F and FR Mk. XIVs were to be refitted with clipped wings. Spitfire XIVs began to arrive in the South-East Asian Theatre in June 1945, too late to operate against the Japanese. In total, 957 Mk. XIVs were built, over 430 of which were FR Mk. XIVs.
After the war, secondhand Mk. XIVs still in good shape were exported to a number of foreign air forces; 132 went to the Royal Belgian Air Force, 70 went to the Royal Indian Air Force and 30 of the reconnaissance version went to the Royal Thai Air Force. The Royal Iraqi Air Force (RIrAF) was another operator, even though only a small one.
In late 1946, five years after the Anglo-Iraqi War had left the RIrAF shattered, the Iraqis reached an agreement with the British under which they would return their surviving Avro Ansons in exchange for the authorization to order more modern and potent fighter aircraft from the UK, namely Supermarine Spitfires and Hawker Furies. The next year, three de Havilland Doves and three Bristol Freighters were ordered, too, and they arrived in early 1947 with a batch of ten refurbished ex-RAF Spitfire F Mk. XIVcs, some of them WWII survivors. All these machines received the original wing tips to better cope with the expected higher ambient temperatures in the Middle Eastern theatre of operations, reinforced aluminum skinning along the wing roots, and they were retrofitted with hardpoints under the wings and the fuselage to carry unguided missiles, bombs and drop tanks, what gave them an additional ground attack capability. The radio equipment was modernized, too, including a DF loop antenna as navigational aid. Despite these standardizations, though, the Spitfires were delivered with a mix of the different canopies.
The RIrAF was still recovering and re-structuring its assets when it joined in the war against the newly created state of Israel in the 1948 Arab-Israeli War. The RIrAF only played a small role in the first war against Israel, though. A few Spitfire F Mk. XIVs as well as Avro Anson training bombers operated from Transjordan airfields from where they flew several attacks against the Israelis. After a series of indiscriminate attacks on Arab capitals, flown by three Boeing B-17s that had been pressed into service by the Israeli Air Force, the governments of Transjordan and Syria demanded that the Iraqis take more offensive action and replace their Ansons with Hawker Furies. However, only six Furies were sent to Damascus to join the Spitfires in the region, and they never encountered any Israeli aircraft during their deployment.
Despite some effective attacks on ground targets by the Spitfires, limited amount of cannon ammunition, RPGs and suitable bombs heavily limited the Iraqi operations. The fighters were mostly used for armed reconnaissance, and three Spitfires were upgraded to FR Mk. XIV standard for this purpose. In 1949 a second batch of eight more Spitfire F Mk. XIVs was delivered from Britain, and in 1951 the RIrAF purchased 20 more Fury F.Mk.1s, for a total of 50 F.Mk.1s single-seaters and 2 two-seaters. They soon replaced the Spitfires in frontline units, even though the machines were still kept in service.
In the early Fifties, thanks to increased income from oil and agricultural exports, the RIrAF was thoroughly re-equipped. In 1951, 15 each of de Havilland Canada DHC-1 Chipmunks, Percival Provosts and North American T-6s were bought to replace obsolete de Havilland Tiger Moth trainers. With these new aircraft the RIrAF Flying School was expanded into the Air Force College. The training curriculum was improved, and the number of students graduating each year was increased. This allowed to form a solid basis for the RIrAF's long-term growth. Also in 1951, the RIrAF bought its first helicopters: three Westland Dragonflies. The RIrAF's first jet fighter was the de Havilland Vampire: 12 FB.Mk.52 fighters and 10 T.Mk.55 trainers were delivered from 1953 to 1955, and they fully replaced the Spitfires. The Vampires were quickly supplemented by 20 de Havilland Venoms, delivered between 1954 and 1956.
Following the formation of the Baghdad Pact, the United States donated at least six Stinson L-5 Sentinels and seven Cessna O-1 Bird Dogs to the RIrAF. The RAF also vacated Shaibah Air Base, and the RIrAF took over it as Wahda Air Base. In 1957, six Hawker Hunter F.Mk.6s were delivered. The next year, the United States agreed to provide 36 F-86F Sabres free of charge.
However, following the 14 July Revolution of 1958, which resulted in the end of monarchy in Iraq, the influence of the Iraqi Communist Party grew significantly. The first commander of the Iraqi Air Force (the "Royal" prefix was dropped after the revolution), Jalal Jaffar al-Awqati, was an outspoken communist, and encouraged prime minister Abd al-Karim Qasim to improve relations between Iraq and the USSR. The Soviets reacted quickly, and in the autumn of 1958 a series of arms contracts was passed between Iraq and the Soviet Union and Czechoslovakia. These stipulated the delivery of MiG-15UTI trainers, MiG-17F fighters, Ilyushin Il-28 bombers, and Antonov An-2 and An-12 transports. The first aircraft arrived in Iraq in January 1959; during the late Sixties and the early Seventies additional MiG-17s may have been purchased and then forwarded to either Syria or Egypt.

The kit and its assembly:
This was a rather spontaneous interim build. The Academy Spitfire was left over from a D-Day combo that contained a Hawker Typhoon, too, and I lacked an idea for the Spitfire for a long time) since I am not a big fan of the aircraft, at least what-if-inspiration-wise). However, when pondering about a potential operator from the very early pos-war period I remembered the Royal Iraqi Air Force and its later Hawker Hunters which retained their NATO-style camouflage (RAF green/grey) despite being primarily operated in a desert environment. This, on a Spitfire…?
From this idea the Academy Spitfire was built almost OOB. Because the kit offers them as an option and for the cool look, I gave the Spitfire four RPGs under each outer wing. The ventral drop tank was taken from a Special Hobby late Spitfire kit. The only other additions are the antenna mast and the non-standard DF loop antenna behind the cockpit, created from thin wire and mounted on a small, streamlined socket.
Painting and markings:
The upper surfaces were painted in standard RAF WWII colors, Dark Green and Ocean Grey, using a mix of Humbrol 163 and 30 for a slightly more bluish WWII-style green and a mix of 106 and 145 for a lightened grey tone, respectively. As an individual contrast and paint scheme variation the undersides and the spinner were painted in RAF Azure Blue (Humbrol 157, lightened up with 47), more appropriate than the standard WWII Medium Sea Grey from the European theatre of operations. The cockpit interior became RAF cockpit green (Humbro,78) while the inside surfaces of the landing gear were painted in Medium Sea Grey (Humbrol 165), reflecting the original undersides’ tone in former RAF service.
Other markings were minimal. The Iraqi triangles were taken from a Balkan Models Su-25 sheet, because their green was rather pale, for more contrast to the surrounding camouflage. RIrAF fin flash was taken from a PM Model Hawker Fury two-seater (a.k.a. “Bagdad Fury”). The tactical code came from an Airfix Hawker Hunter (from an optional Kuwaiti machine). This looked O.K. but somewhat bleak, so I added more markings. I could not find any evidence for special ID markings on Iraqi aircraft during the Arab-Israel war, but to add an eye-catcher I gave the aircraft white ID bands on the wings and on the fuselage – inspired by markings carried by Egyptian aircraft (e. g. Spitfires) during the conflict, but somewhat simplified, without black trim. They were created from generic white decal sheet material.
After some soot stains around the gun ports and the exhausts, the model was sealed with matt acrylic varnish.
A relatively simple project and just a fictional livery - but the Iraqi Spitfire looks pretty cool, especially the ID stripes add a special touch. The European RAF scheme looks a bit off on an aircraft that would be delivered to the Middel East, but the Iraqi Air Force operated British types like the Hunter in this guise, and later Su-22 fighter bombers carried a similarly murky camouflage in very dark green and earth brown.
