Some background:
The Korean People's Army Air and Anti-Air Force began as the "Korean Aviation Society" in 1945. It was organized along the lines of flying clubs in the Soviet Union. In 1946, the society became a military organization and became an aviation division of the Korean People's Army (KPA). It became a branch of the army in its own right in November 1948. The KPAF incorporated much of the original Soviet air tactics, as well as North Korean experience from the UN bombings during the Korean War.
North Korea’s first indigenous jet fighter aircraft, the Wonsan Aircraft Works 여-1 (known as “W-1” outside of the country), started its existence in China as the Shenyang J-3 (Jianjiji = fighter). The J-3 was a project to exploit the knowledge and hardware gained through the license production of the Soviet MiG-15UTI trainer, locally designated JJ-2 (Jianjiji Jiaolianji – fighter trainer), a study that was primarily intended to improve China’s aircraft industry and the country’s respective engineering know how after the Korean War. The Soviet VVS and PVO had been the primary users of the MiG-15 during the Korean war, but not the only ones; it was also used by the PLAAF and KPAF (known as the United Air Army).
The J-3 was designed during the Korean War between 1952 and 1953 and two prototypes were built with Soviet help and tested in 1953, but the aircraft came too late – and it was not regarded as a successor or even an alternative to the Soviet MiG-15, because it lacked modern features like swept wings. The J-3’s design drew more on American rather than British inspiration, having elected to use features such as a very thin (but almost straight) wing akin to the Lockheed P-80 Shooting Star and a basic configuration comparable to the North American F-86 Sabre. Due to its conceptual interceptor role, an emphasis had been placed on a fast rate of climb. Power came from a Klimov VK-1 centrifugal-flow turbojet, a derivative of the British Rolls-Royce Nene Mk.104B that also powered the MiG-15. Armament consisted of four 23 mm (0.906 in) Nudelman-Suranov NS-23 autocannon under the nose.
The J-3’s rate of progress on the project was such that, within 15 months of design work having formally started, the first prototype had been fully constructed. On 28 October 1953, the first J-3 fighter prototype conducted its first flight, even though it still lacked pressurization, armament, and other military equipment. Gradually, new hardware was integrated and tested, and a second aircraft joined the tests in January 1954. Flight tests followed quickly and showed that the J-3 was easy to fly and had exceptional performance and maneuverability for a straight-wing aircraft. Unfortunately, it soon became clear that the laminar flow section used for the original tail unit was totally unsuitable, with extremely severe buffeting setting in at 500 km/h (310 mph). The buffeting was so bad that the test pilots were thrown about in the cockpit, banging their head on the canopy, and the needles fell off all the flight instruments. Fortunately, accidents could be avoided, and the tailplane section was changed with much improved results.
The gun armament caused troubles, too. Firing all four NS-23 at once made the robust engine surge – a problem that did not occur on the MiG-15, but it only carried two of these weapons. A remedy was eventually found through the introduction of a slightly elongated nose that kept the air intake further away from the gun blast shock waves. The flight and test program lasted until 1955, and a total of five J-3 prototypes were built, but with no serious plan to put this aircraft into series production, even more so after China had been offered to produce the even more modern and capable Soviet MiG-17 fighter under license as the J-5. In the People's Republic of China (PRC), an initial MiG-17F was assembled from parts in 1956, with license production following in 1957 at Shenyang. The Chinese-built version was/is known as the Shenyang J-5 (for local use) or F-5 (for export). After this decision, the J-3 program was stopped, but the machines were retained in flightworthy condition as testbeds and chase planes by the PLAAF until the late Sixties
However, this was not the end of the J-3. After fighting had ended on 27 July 1953 when the Korean Armistice Agreement was signed, the Korean People's Army Air and Anti-Air Force (KPAAF) was keen to boost its capabilities and build a domestic aircraft industry, beyond the option to produce existing designs in license. Turning to its main sponsor China, North Korea was offered the plans for the J-3 and its tools, together with a supply of Chinese-built VK-1 engines. Even though the J-3 did not represent the state-of-the-art in jet fighters anymore, it was the best option for an industrial quickstart and until 1956 a dedicated production site for the J-3 was built at Wonsan, leading to the Wonsan Aircraft Works (Wonsan hang-gong-gi jag-eob , 원산 항공기 작업) and its first military product, the 여-1 (Yeo-1 = W-1). When NATO became aware of the aircraft it received the reporting code name “Freshman”.
However, despite the J-3’s plans and tools at hand, the W-1’s production was hampered by the lack of experience, sub-optimal materials, and poor logistics (esp. concerning vital imported components like the Chinese WP-5 engine, a license-built VK-1). Consequently, it took almost three years to roll out the first pre-serial production aircraft in 1959, and even then, the W-1 was plagued with material and reliability problems. Furthermore, once the W-1 became operational in 1961, the aircraft had become outdated. The W-1 had been designed to intercept straight-and-level-flying enemy bombers, not for air-to-air combat (dogfighting) with other fighters. The subsonic (Mach .76) fighter was effective against slower (Mach .6-.8), heavily loaded U.S. fighter-bombers from the Fifties, as well as the mainstay American strategic bombers during the aircraft's development cycle (such as the Boeing B-50 Superfortress or Convair B-36 Peacemaker, which were both still powered by piston engines). It was not however able to intercept the new generation of British jet bombers such as the Avro Vulcan and Handley Page Victor, which could both fly higher. Most W-1s were initially used as night fighters – even though they lacked any on-board radar and the pilot had to rely on visual contact and/or radio guidance from ground stations to make out and close in on a potential target. The USAF's introduction of strategic bombers capable of supersonic dash speeds such as the B-58 Hustler and General Dynamics FB-111 rendered the W-1 totally obsolete in front-line KPAAF service, and they were quickly supplanted by supersonic interceptors such as the MiG-21 and MiG-23.
The rugged aircraft was not retired, though, and found use as ground attack aircraft (despite its limited payload of around 2 tons) and as an advanced fighter trainer. Total production numbers are uncertain, but less than 100 W-1s were produced until 1969, with no further variants becoming known. In 1990, probably forty were still operational, and even after 2000 some KPAAF W-1s were still flying.

The kit and its assembly:
I always thought that the tubby Dassault Ouragan had something “Soviet-ish” about it, looking much like one of the obscure early Yakowlew jet fighter prototypes (e .g. the straight-wing Yak-25 [first use of this designation in 1947] or the swept-wing Yak-30) around 1950. With this idea I had stashed away a Heller Ouragan for a while, and recently wondered about an indigenous North-Korean aircraft that could have emerged after the Korean War? The Ouragan looked like a good basis, and so this project started as a simple conversion of the Heller kit.
While most of the airframe was retained, I made some cosmetic changes to change the aircraft’s looks and add a Warsaw Pact flavor. The characteristic wing tip tanks disappeared, and the wings’ ends were rounded off. The fin tip was extended with a piece of 1.5 mm styrene sheet and a different fin shape was sculpted from it. The original stabilizers were replaced with what I think are stabilizers from a VEB Plasticart 1:100 An-24 – they better match the wing shape than the OOB parts!
The cockpit was taken OOB, I just replaced the ejection seat with a different piece from a KP 1:72 MiG-19. The air intake was modified with the opening from a Heller 1:72 F-84G, extending and narrowing it slightly, even though the internal splitter plate (which also bears the front wheel well) was retained. The landing gear was also basically taken OOB, but the main wheels were now mounted on the outside position (with an adaptation of the covers), and the front wheel was moved 3 mm further forward, to compensate for the slightly longer nose section, and its cover was modified accordingly. The flaps were lowered, primarily because this modification is easy to realize on this kit and it makes the simple aircraft look “livelier”, and the canopy was cut into three parts for open display.
Pylons were added under the wings, together with drop tanks from a Hobby Boss 1:72 MiG-15. The same source provided the swept antenna mast behind the cockpit and the small but characteristic altimeter sensors under the wings. As a final twist of “Sovietization” I added small fences to the wings, made from styrene profiles – they would not be necessary on the aircraft’s straight wings, but they help change the model’s overall look. 😉
Building the Heller Ouragan was a straightforward affair, even though the plastic of the recent re-boxing I used was pretty soft and took long to cure after gluing parts together. A real problem occurred when I tried to close the fuselage halves, though, because the parts did not align well behind the cockpit, as if they were warped? The walls were rather thin, too, and as a result a lot of PSR went into the spine and the ventral area behind the wings, which mismatched badly. The rather thin material in these areas did not help much, either. I have built the Ouragan before, and I do not remember these massive troubles?!
Painting and markings:
I initially considered a North-Korean night fighter camouflage from the Korea War, but since the aircraft would have been introduced into service after the open hostilities, I rather settled for a very dry NMF finish with minimal markings. Therefore, the model received an overall coat with “White Aluminum” from the rattle can and a light overall rubbing treatment with graphite to emphasize the raised panel lines and add a slightly irregular metallic shine to the paint. Since they had disappeared through PSR, I also added/recreated some panel lines with a soft pencil.
The cockpit interior was painted in medium grey and Soviet cockpit turquoise, the landing gear and its wells became metallic-grey (Humbrol 56). The areas around the exhaust and the guns were painted with Revell 91 (Iron), the only color contrasts are red trim tabs.
The large KPAAF roundels with a white background came from a Cutting Edge MiG-15 sheet, the large red tactical code was left over from an unidentifiable “Eastern Bloc” model’s decal sheet. After some more graphite treatment around the guns and the tail section the model was sealed with a coat of semi-gloss acrylic varnish (Italeri), resulting in a nice metallic shine that looks better than expected on this uniform aircraft.
Well, this converted Ouragan looks pretty dull at first sight, due to its simple livery. But this makes it pretty plausible, and the small cosmetic changes add a serious Soviet-esque touch to the aircraft.
