Independent State of Croatia (1942)
Fighter –  16 Operated

Following the creation of the Nezavisna Država Hrvatska (Independent State of Croatia), its Air Force was plagued with many problems from the start, including a lack of modern aircraft. While generally heavily reliant on the Germans to provide them with better equipment, they were unwilling to secure any deliveries of aircraft. To resolve this issue the NDH’s Air Force officials managed to persuade Italy to sell them 10 Fiat G.50bis fighters, which remained in use up to 1945.

A Brief History of the NDH

Following the end of the First World War, Kraljevina Srba Hrvata i Slovenaca (The Kingdom of Serbs, Croats, and Slovenes – SHS) was formed in December of 1918 with the aim of uniting all Southern Slavs. This new state was, at least in theory, based on the principles of equality for these three nationalities. In reality, this Kingdom was a politically and ethically divided country. During the 1920s, there were huge political disagreements between the major parties which brought about questions regarding the continued existence of the Kingdom of SHS. This division was especially noted between the Serbian and Croatian politicians, which ultimately culminated in the assassination of several Croatian Peasant Party members, including the leader, Stjepan Radić, by a Serbian Politician in 1928.

On 6th of January, 1929, King Aleksandar Karađorđević, in an attempt to avoid the incoming political crisis, led the country into a dictatorship by abolishing parliament. He also introduced a number of political changes, including changing the name of the country to Kraljevina Jugoslavija (Kingdom of Yugoslavia.) This essentially did not resolve any of the existing problems, as inter-ethnic tensions persisted. During the early 1930s, the first mentions of Croatian Ustaše (the precise meaning is unknown, but could be roughly translated as insurgent) ultranationalist revolutionary organizations began to appear in Yugoslavia. Their main aim was the liberation of the Croatian people from Yugoslavia, by all means necessary, even by force. One of the most prominent figures of this organization was Ante Pavelić.

The Ustaše organization participated in the assassination of the Yugoslav King, Alexander Karađorđević, in Marseille in 1934. This assassination backfired to some extent for the Ustaše organization. Not only did it not lead to the collapse of Yugoslavia, but relations with Italy also improved under the Regent Prince Pavle Karađorđević in the following years. This led the Italian authorities to effectively end their support for the Ustaše and even arrested some of its members, including Pavelić.

After years of inactivity, the Ustaše benefited when the Yugoslavian government, which supported the Axis, was overthrown by pro-Allied officers in a military coup at the end of March 1941. Adolf Hitler almost immediately issued an order that Yugoslavia should be occupied. The Italians, preparing to join the war against Yugoslavia, began to support the Croatian Ustaše movement once again. With the collapse of the later Kingdom of Yugoslavia during the Axis invasion after the short April War of 1941, Croatia, with German aid, was finally able to declare independence, albeit becoming a fascist puppet state. Ante Pavelić was chosen as the leader of this puppet state. Officially, the NDH was announced on 10th April 1941. The new state received a significant territorial expansion by annexing most of western Yugoslavia, including Bosnia, parts of Serbia, and Montenegro. The Adriatic coast, while nominally part of the NDH, was actually controlled by the Italians until 1943.

Formation of the NDH Air Force

Following the collapse of the Kingdom of Yugoslavia, NDH began organizing its newly-created armed forces. Its Air Force was created on the 19th of April, 1941. The leadership of the new Air Force was given to Colonel Vladimir Kren. Immediately, work began on creating adequate structural organization, acquiring manpower, and procuring equipment. Initially, plans for arming this Air Force were ambitious, including some 140 modern aircraft, such as the Ju 88 and Me 109. Its officials were quite disappointed as Germans were not willing to provide these. Instead, the NDH officials had to make do with the leftovers of the Former Royal Yugoslav Air Force, which was in German hands. NDH officials made a request that included over 50 aircraft. The Germans once again disappointed them and gave NDH only those aircraft that were mostly obsolete, while transferring the better aircraft, like the Hurricanes, to Romania instead. The only other way to acquire more capable aircraft was to ask the Italians. This is what the NDH Air Force officials did in early 1942.

The Fiat G.50 brief history

During the thirties, the Italian Ministry of Aviation (Ministero dell Aeronautica) was interested in adopting a new, all-metal monoplane fighter and ground-attack aircraft for the Italian Air Force. In April of 1935, engineer Giuseppe Gabrielli began working on a new low-wing, all-metal plane named G.50. On 28th September 1935, Gabrielli submitted his project to the Ministry of Aviation. Military officials were impressed by the design and asked him to proceed with its work. As Fiat’s production capacities were overburdened, work on this new project was instead moved to the CMASA works at Marina di Pisa, part of Fiat since 1931. Giuseppe Gabrielli was finishing his last drawings and the list of needed materials and equipment in June 1936.

The prototype was finally ready at the beginning of 1937 and was transported to the city of Turin for further testing. This prototype, under registration number MM 334, made its first test flight on 26th February 1937. Once accepted for service, the Fiat G.50 would become the first Italian all-metal fighter. Between 1938 to 1943 some 774 to 791 of all versions of the G. 50 would be built. These saw combat service starting from the Spanish Civil War, until 1943 when the few surviving aircraft were reassigned to secondary roles.

In Yugoslavia

The Fiat G. 50 participated during the short Invasion of Yugoslavia in April 1941. Two fighter groups, the 24th, and 154th, which had 53 G.50 fighters in total were allocated for this operation. They mostly performed a few escort missions. Due to the rapid collapse of Yugoslavia’s Royal Army, these saw limited actual combat use, if any. Afterward, the Fiat G.50 was allocated to other fronts. During 1942 and 1943, limited numbers of these aircraft were used for ground attack operations against the Yugoslavian Partisans.

In NDH’s Hands

By 1942, most of the available aircraft in NDH Air Force were in poor condition, mostly due to a general lack of spare parts. NDH Army officials approached Italy with a request for 9 improved Fiat G.50 and one two-seater version. The Fiat G.50bis were slightly modified versions that had an increased fuel load, a redesigned rear fuselage and vertical stabilizer, better glazing of the cockpit, and other minor changes. But in essence, it did not offer many improvements compared to the basic version. The G.50 B bipost (two-seater) was a modified G.50 fighter version with a new cockpit and dual controls for a pilot and trainer. The front section of the cockpit was fully enclosed, in contrast with the rear which was open. The main armament was removed on the G.50 B. This version was very successful, as it was easy to build and offered almost the same flying performance as the single-seat version.

A group of six NDH pilots was sent to the Fiat company in Torino for training in January 1942. The entire acquisition process of new aircraft took several months to complete. The 9 Fiat G.50bis (serial number MM.6178 to 6186) were finally allocated to the NDH. These arrived in Croatia in April 1942. The Fiat G.50B two-seater took even more time to be delivered, arriving in late June 1942. These would be stationed on the Borongaj airfield near Zagreb. Initially, these were used for pilot training. Due to the poor condition of the airfield, two were lightly damaged during landing.

Combat Use

Almost from the start, the new NDH regime began the persecution of all non-Croatian citizens. The Serbian, Roma, and Jewish populations were especially targeted, with numerous atrocities and arrests. Croatians who did not agree with this regime were also persecuted. In response to the NDH’s actions against Yugoslavian civilians, resistance movements began to emerge on its territory. Their Air Force was used in various roles during this time, but due to generally obsolescence of equipment, their impact would be quite limited.

The acquisition of more aircraft like the Fiat G.50 offered a slight increase in its offensive capabilities. Once in service, these received new registration numbers ranging from 2501 to 2509. The single Fiat G.50B received the 3510 designations. In July, five would be allocated to the Rajlovac airfield near Sarajevo. In September three were moved to the Banja Luka to be part of the 16th squadron.

After April 1943 most were pulled back to Zagreb where they were attached to the 1st Squadron. When Italy capitulated to the Allies, all warring parties in Yugoslavia rushed in to take over the abandoned Italian weapons, armored vehicles, and a few remaining aircraft. At Zadar airfield, there were six Fiat G.50 aircraft. These would be captured by the NDH forces. Three of them received 5686, 5956, and 5186 designations. The newly acquired fighters were primarily positioned at Kurilovac and Velika Gorica airfields.

By 1944 it was becoming obvious that the Axis would lose the war, as a result many soldiers and pilots from the NDH Army and Air Force tried to escape to the Partisans. On the 2nd of September 1944, air force pilot Andrija Arapović with a Fiat G.50 (reg. Num. 3505) escaped to the island of Vis, under the control of the Yugoslav communist Partisans. Partisan forces put the captured G.50 to use during the war and it would remain in service up to 1946. An interesting fact about Andrija Arapović’s G.50 aircraft is that it still exists today and can be seen in the Belgrade Military Aviation museum near the Nikola Tesla Airport in Serbia. This is the only surviving example of a G.50 in the world. Another Fiat G.50 escaped joining the Allies in Italy.

By this point the Allies had achieved almost complete air supremacy over southern Eastern Europe, thus flying the slower Fiat G.50 became quite dangerous. In April 1944 several NDH aircraft, including two Fiat G.50, were destroyed in an Allied bombing run on Borongaj. Due to their obsolescence, even the NDH’s best fighters could do little against Allied bombers. In addition, the chronic lack of fuel led to a reduction in combat flights. By mid-September 1944, only 7 aircraft were listed as operational. In October most were allocated to the 2nd Squadron, which was also equipped with MS 406 fighters. When the Partisans liberated Zagreb, some 9 aircraft in various conditions would be captured. Some would be put to use after the war, but their use would be limited.  These would be removed from service by the 1st of April 1946.

Technical Characteristics 

In NDH service no known modifications were made on the Fiat G. 50. The G.50 was a single-seat, low-wing, all-metal fighter plane. The main fuselage was made from four angular-shaped longerons. The wing construction consisted of a center section which was made of a steel tube connected to the lower fuselage and two metal spars connected with ribs. The fuselage, wing, and tail were covered with duralumin sheets. The only fabric-covered parts were the movable control surfaces in the wings and the tail. It was powered by the 840 hp (626 kW) Fiat A 74 RC 38, a 14-cylinder radial piston engine. An all-metal three-blade propeller produced by Fiat was used.

The G.50 was equipped, like most modern aircraft of the time, with inward retracting landing gear, but the rear tail wheel was fixed. In later improved versions, the rear tail wheel was changed to a retractable type.

The main armament consisted of two forward-firing 12.7mm Breda-SAFAT heavy machine guns, with some 150 rounds of ammunition for each machine gun. The guns were placed behind the upper engine cowl and were synchronized in order not to damage the propeller.

Conclusion

The Fiat G.50 was one of few modern fighters available for NDH service. Their use would be greatly hampered by ever-increasing Allied Air supremacy, lack of fuel, and fear of their pilots defecting. Despite being acquired in relatively small numbers many of them would survive the war albeit in poor condition, while some would see a few more years of service by the newly created Yugoslav Air Force.
