The Royal Yugoslav Air Force (VVKJ) operated the German Messerschmitt Bf 109E-3 fighter aircraft from August 1939 to April 1941. During that period, the VVKJ obtained 73 Messerschmitt Bf 109E-3s from Germany, marking the second-largest export sale of the model. When the country was drawn into World War II by the German-led Axis invasion of April 1941, a total of 46 Yugoslav Messerschmitt Bf 109E-3s were serviceable. They achieved some successes against Luftwaffe aircraft, but all Yugoslav Messerschmitt Bf 109E-3s were destroyed or captured during the 11-day invasion.

During World War II, the Yugoslav Partisans captured ten Messerschmitt Bf 109s. These small numbers were boosted by a 1947 agreement with Bulgaria, under which Yugoslavia eventually received about 120 G and K models to help equip the fledgling Yugoslav Air Force. Due to lack of spare parts, all Yugoslav Bf 109s were withdrawn from service in 1954.

Acquisition

In 1938, the VVKJ began modernising its fleet of aircraft. Following protracted negotiations, it ordered 50 Messerschmitt Bf 109E-3 fighter aircraft from Nazi Germany. This was followed by a further order of 50 aircraft.^[1] Between August 1939 and late 1940,^[2] a total of 73 aircraft were delivered under these contracts. This was the second-largest foreign purchase of the E variant of the fighter, after Switzerland.^[1]

Operational service

Royal Yugoslav Air Force

Once in service, the Bf 109E-3s were used to equip the 31st Fighter Group of the 2nd Fighter Regiment based at Knić, and the 32nd and 51st Fighter Groups of the 6th Fighter Regiment based at Prnjavor and Zemun, both on the outskirts of Belgrade. The Bf 109E-3 was also operated by the 702nd Liaison Squadron of the 1st Fighter Brigade based at Zemun, and the Independent Fighter Squadron of the 81st Bomber Group and the Air Training School, both based at Mostar. All of these aircraft were deployed in the fighter/interceptor role.^[3]^[4] Immediately prior to the German-led Axis invasion of Yugoslavia in April 1941, 64–65 of the original 73 Bf 109E-3s were serviceable. They were allocated as follows:^[3]^[4]^[5]

Commencing at 06:45 on 6 April, the Luftwaffe launched Operation Retribution, a series of concerted bombing attacks on Belgrade that coincided with air and ground attacks throughout the country. Several waves of German aircraft approached Belgrade during the day, initially Junkers Ju 87 "Stuka" dive-bombers escorted by fighters. All of the Bf 109E-3s of the 51st Fighter Group scrambled to meet the first onslaught, and they were soon joined by the Messerschmitts of 32nd Fighter Group. Seven claims were made by the pilots of the 102nd Squadron of the 51st Fighter Group, losing five aircraft in return. The 32nd Fighter Group Messerschmitts claimed another four bombers for the loss of two of their own, although several more Yugoslav fighters were hit and damaged.^[6] During the initial melee, Yugoslav anti-aircraft guns had fired at the Yugoslav Messerschmitts as well as the German ones, unable to distinguish between them.^[7]

Yugoslav Air Force

In October 1944, advancing Partisan forces captured eight Bf 109Gs at Kovin, which were supplemented by more Bf 109s in May 1945. Some of these aircraft were made airworthy and pressed into service, flying sorties against Chetnik forces in Bosnia in early May 1945 and against Croat forces in Posavina late that month.^[8] They saw little use after the end of the fighting, and were scrapped in 1947.^[9] In 1947, Bulgaria realised that it had a surplus of aircraft above what would be allowed by the Paris Peace Treaties, and rather than scrap them, it was decided that they would be transferred to Yugoslavia, reinforcing the newly established Jugoslovensko Ratno Vazduhoplovstvo (JRV) or Yugoslav Air Force. An initial delivery of 48 dismantled Bf 109s was made in March 1947, and in July that year agreement was made to transfer another 43 Bf 109s, with 12 aircraft being converted to two-seaters.^{[lower-alpha 1]} In 1949, political disagreements between Yugoslavia and the Soviet Union (known as the Tito–Stalin split) caused deliveries from Bulgaria to be stopped after 53 single-seaters (known as Me 109s rather than Bf 109s in JRV service) and six two seaters (designated UMe 109s) had been received.^[10] Three more single-seaters were converted to UMe 109 trainers in 1951.^[11]

The Me 109s equipped the 83rd IAP (Iovacki Avio Puk - fighter regiment) and the 172nd IAP.^[12] Both units suffered high accident rates,^[13] and by the end of 1951, operational strength had dropped to 26 single-seaters and 7 two seaters.^[14] In 1952, Yugoslavia received large numbers of Republic F-47D Thunderbolts from the United States, together with expensive stocks of spares, and this allowed the Messerschmitts to be replaced that year, with the aircraft going into storage. They were scrapped in 1955.^[14]

Surviving examples

Two ex-JRV Bf 109Gs survived the retirement and scrapping of Yugoslavia's Bf 109s:

Bf 109G-2 Werknummer 14792: Built at Wiener Neustadter Flugzeugwerk (WNF) in January 1943. Service with JRV from December 1948. Displayed at Aeronautical Museum Belgrade since 1961 and displayed as 'White 63'.^[11]
Bf 109G-10 Werknummer 610937: Built at WNF in January 1945. To JRV in March 1947. To faculty of Mechanical Engineering, Belgrade 1952 and sold to US 1986.^[11]

Notes

↑ These two seaters had several differences from the Messerschmitt designed G-12 conversion.^[9]

The Messerschmitt Bf 109 is a German World War II fighter aircraft that was, along with the Focke-Wulf Fw 190, the backbone of the Luftwaffe's fighter force. The Bf 109 first saw operational service in 1937 during the Spanish Civil War and was still in service at the end of World War II in 1945. It was one of the most advanced fighters when it first appeared, with an all-metal monocoque construction, a closed canopy, and retractable landing gear. It was powered by a liquid-cooled, inverted-V12 aero engine. It was called the Me 109 by Allied aircrew and some German aces, even though this was not the official German designation.

The Ikarus IK-2 was a 1930s high-wing, single-seat, monoplane fighter aircraft of Yugoslav design built for the Royal Yugoslav Army Air Force. The IK-2 was designed by French-trained engineers Kosta Sivčev and Ljubomir Ilić, who saw the desirability of developing a home-grown aircraft industry. A gull-wing design, it was armed with a hub-firing autocannon and fuselage-mounted synchronised machine guns. Just 12 production models were built, as the aircraft was obsolescent at the time it was brought into service in 1935, and only eight were serviceable at the time of the German-led Axis invasion of Yugoslavia in April 1941. After the defeat of Yugoslavia, the remaining four aircraft were taken onto the strength of the air force of the Axis puppet state, the Independent State of Croatia, but none survived the war.

The Rogožarski IK-3 was a 1930s Yugoslav monoplane single-seat fighter, designed by Ljubomir Ilić, Kosta Sivčev and Slobodan Zrnić as a successor to the Ikarus IK-2 fighter. Its armament consisted of a hub-firing 20 mm (0.79 in) autocannon and two fuselage-mounted synchronised machine guns. It was considered comparable to foreign aircraft such as the Messerschmitt Bf 109E and came into service in 1940. The prototype crashed during testing; twelve production aircraft had been delivered by July 1940.

Operation Retribution, also known as Operation Punishment, was the April 1941 German bombing of Belgrade, the capital of Yugoslavia, in retaliation for the coup d'état that overthrew the government that had signed the Tripartite Pact. The bombing occurred in the first days of the German-led Axis invasion of Yugoslavia during World War II. The Royal Yugoslav Army Air Force (VVKJ) had only 77 modern fighter aircraft available to defend Belgrade against the hundreds of German fighters and bombers that struck in the first wave early on 6 April. Three days prior, VVKJ Major Vladimir Kren had defected to the Germans, disclosing the locations of multiple military assets and divulging the VVKJ's codes.

Mato Dukovac was the leading Croatian fighter ace of World War II, credited with between 40 and 44 confirmed victories. He joined the Air Force of the Independent State of Croatia following the Axis invasion of Yugoslavia in April 1941, and then the Luftwaffe, with which he flew combat missions on the Eastern Front. His tours of the Eastern Front spanned October and November 1942, February to June 1943, and October 1943 to March 1944. He defected to the Soviet Union on 20 September 1944 and was returned to Yugoslavia in November 1944. He worked as a flight instructor for the Yugoslav Air Force in Pančevo and Zadar before defecting to Italy in April 1945.

The Messerschmitt Bf 109 was a German World War II fighter aircraft designed by Willy Messerschmitt and Robert Lusser during the early to mid-1930s. It was one of the first true modern fighters of the era, including such features as all-metal monocoque construction, a closed canopy, a retractable landing gear, and was powered by a liquid-cooled, inverted-V12 aero engine.

Air warfare during World War II in Yugoslavia pitted the Yugoslav Air Force, both Royal and NOVJ, United States Army Air Force (USAAF), the Royal Air Force (RAF), including the Balkan Air Force, and Soviet Air Forces against the German Luftwaffe, the Italian Regia Aeronautica and the Air Force of the Independent State of Croatia. The latter provided the majority of the support for the ground operations against the Partisans. The Allied forces engaged in an extensive bombing campaign in an effort to weaken the Axis hold on the country.

Due to the Messerschmitt Bf 109's versatility and time in service with the German and foreign air forces, numerous variants were produced in Germany to serve for over eight years with the Luftwaffe. Additional variants were produced abroad totalling in 34,852 Bf 109s built.

In late 1937, the Royal Yugoslav Air Force placed an order with Hawker Aircraft for twelve Hawker Hurricane Mk I fighters, the first foreign purchase of the aircraft. The VVKJ operated the British Hawker Hurricane Mk I from 1938 to 1941. Between 1938 and 1940, the VVKJ obtained 24 Hurricane Mk Is from early production batches, marking the first foreign sale of the aircraft. Twenty additional aircraft were built by Zmaj under licence in Yugoslavia. When the country was drawn into World War II by the German-led Axis invasion of April 1941, a total of 41 Hurricane Mk I's were in service as fighters. They achieved some successes against Luftwaffe aircraft, but all Yugoslav Hurricanes were destroyed or captured during the 11-day invasion.
