The Story

The Soko G-2 Galeb: how Yugoslavia built its own jet school

On 3 July 1961 Captain Ljubomir Zekavica lifted a slim, straight-winged jet off the runway on its first flight. The prototype, serial 23001, was the product of a programme begun in 1957 at the Aeronautical Technical Institute (VTI) in Žarkovo near Belgrade, with a design team led by Dr Zlatko Rendulić. Tito’s Yugoslavia sat between the blocs and wanted its own aviation industry rather than total dependence on either superpower. A home-built jet trainer was the obvious place to start: it would teach pilots, keep engineers busy and could be sold abroad. The answer was the G-2 Galeb (“Seagull”), the first jet aircraft designed in Yugoslavia to enter series production.

The recipe was conservative and sensible. A low, straight wing with tip tanks, tandem seats for student and instructor, wing-root intakes and a single British Viper turbojet of about 2,500 lb (11.1 kN) thrust. More than half of the aircraft’s production value, by one Serbian estimate, was British-sourced. The Galeb was shown abroad at the 1963 Bourges air show, and production began at the Soko factory in Mostar, Herzegovina, with the first aircraft taken on charge by the air force in 1965. It was rugged enough to operate from grass and was cleared to +8 g, so it could teach weapons delivery as well as circuits and aerobatics. Two 12.7 mm guns in the nose and four underwing hardpoints made it a light-attack aircraft in all but name.

Between 1965 and 1985 Soko built 248 Galebs. Around 132 went to the Yugoslav Air Force Academy, which used them to turn out the great majority of the country’s military pilots; most of the rest went to Libya, with a handful to Zambia. The airframe also fathered the single-seat J-21 Jastreb attack aircraft and, later, the swept-wing G-4 Super Galeb. When Yugoslavia broke apart, Galebs flew ground-attack sorties over Croatia and Bosnia; in Libya, one was destroyed by a French Rafale in 2011. Many more found their way to private owners in the United States, Britain, Australia and Serbia, where the type is still displayed in the air, more than sixty years after the prototype first flew.

Simple, strong and honest: the jet that taught Yugoslavia to fly fast.248 built — Mostar, 1965–1985
01The G-2 Galeb’s origins: a non-aligned air force builds its own trainer

Yugoslavia’s post-war air force flew a mixture of Soviet piston types, then American jets supplied under military aid in the 1950s, including the T-33. After the break with Stalin in 1948 and a later cooling with Washington, Belgrade wanted an industrial base of its own. The Aeronautical Technical Institute at Žarkovo was given the task of a jet trainer in 1957, and the Soko works in Mostar began building prototypes in 1959.

The choice of engine shaped the aircraft. The Bristol Siddeley (later Rolls-Royce) Viper was a simple, light turbojet already powering trainers such as the Jet Provost and the Aermacchi MB-326. Buying it in Britain gave Yugoslavia a proven powerplant and kept the programme out of the Soviet supply chain. The resulting Galeb was not radical, but it did not need to be: it gave the air force a modern jet trainer built at home, and it gave Soko the experience it would later use on the Jastreb, the Super Galeb and the J-22 Orao.

The first prototype reached 812 km/h in testing. A second prototype and a pre-series followed, and the type was formally taken into the air force inventory on 30 July 1965. Yugoslav service designations used the name Galeb; the export model for Libya and Zambia, offered from the mid-1970s, was the G-2A-E.

Design & Engineering

What makes the Soko G-2 Galeb special

01

One Viper, no frills

The Galeb is powered by a single Viper 11 Mk 22-6 turbojet of about 2,500 lb thrust, fed by intakes in the wing roots. The Viper was designed as a short-life engine for target drones and grew into a dependable trainer powerplant: simple to start, tolerant of rough handling and easy to change. In the Galeb it gives a top speed of around 812 km/h at altitude and a climb to 9,000 m in a little over ten minutes, modest by fighter standards but brisk for a student fresh from piston aircraft.

02

Built for grass and gunnery

The straight wing, sturdy tricycle undercarriage and low wing loading let the Galeb operate from grass strips, with take-off runs commonly quoted around 490 m on grass. Yugoslav doctrine expected aircraft to disperse to secondary fields and roads in war, and the trainer was built with that in mind. Two 12.7 mm machine guns in the nose and four underwing hardpoints for bombs and rockets meant the same aircraft that taught circuits could also teach air-to-ground weapons delivery.

03

A forgiving classroom

Tandem seating puts the instructor behind the student, and the airframe is stressed to +8 / −4 g. Galeb instructors remember it as easy to learn: retired Colonel Mile Nežić, one of the first pilots to ferry the type into service in 1965, told an anniversary gathering in 2021 that students went solo in about eight hours on the Galeb, against around thirty on the types he had trained on before. Wing-tip tanks extend endurance to around two and a half hours.

02The G-2 Galeb’s family: Jastreb, Galeb 3 and Super Galeb

The Galeb airframe proved adaptable. Soko developed a single-seat light-attack derivative, the J-21 Jastreb, with a more powerful Viper, extra guns and heavier underwing loads; it served Yugoslavia and Libya alongside the Galeb. A two-seat Jastreb trainer followed. In 1970 a single Galeb 3 prototype flew, exploring an improved version that did not enter production.

The real successor was the G-4 Super Galeb, a swept-wing, higher-performance advanced trainer that flew in 1978 and gradually took over the advanced stage of Yugoslav training. The Galeb carried on as the basic jet trainer through the 1980s, and Soko delivered the last examples to the Yugoslav Air Force in January 1981 and to export customers until the mid-1980s.

Costs & production

Production
248 built at Soko, Mostar, 1965 to 1985
Programme
Designed from 1957 at VTI Žarkovo; prototype first flight 3 July 1961
Cost per flight hour
No official figure published; for a privately operated Galeb, roughly US$2,500 to 4,000 per hour is a reasonable estimate, based on the fuel burn of a Viper-class turbojet and typical civil jet-warbird maintenance
03The G-2 Galeb’s variants: from prototype to export model
  • Galeb (G-2) prototypes: two prototypes, the first (23001) flying on 3 July 1961.
  • G-2A: main production version for the Yugoslav Air Force, armed with two 12.7 mm guns and underwing stores; about 132 delivered.
  • G-2A-E: export model offered from the mid-1970s with updated equipment; the bulk went to Libya, with two to Zambia.
  • G-2Š: unarmed trainer version.
  • Galeb 3 (G-3): single improved prototype, first flown in August 1970; not produced.
04The G-2 Galeb’s operating costs: cheap jet time for private owners

Neither Soko nor the Yugoslav Air Force published per-hour costs, so any figure is an estimate. The Viper is a thirsty engine by modern standards, and a Galeb in civil hands typically burns several hundred litres of jet fuel an hour; add engine reserves, airframe inspections and insurance and a private owner is plausibly spending US$2,500 to 4,000 per flying hour. That still made the Galeb one of the cheaper ways into private jet ownership after the late 1980s, when warbird dealers bought at least a dozen from Yugoslavia, and it explains why Serbian civil operators can still afford to display the type.

Stories & eyewitnesses: the G-2 Galeb in war and peace

Record

First flight at Žarkovo’s doorstep

On 3 July 1961 Yugoslavia flew its first home-designed jet destined for series production.

Read the full story
Captain Ljubomir Zekavica took prototype 23001 aloft on 3 July 1961. Behind him lay four years of work at the Aeronautical Technical Institute, where Dr Zlatko Rendulić’s team had shaped a straight-winged, Viper-powered two-seater, and two years of prototype construction at Soko in Mostar. The prototype went on to reach 812 km/h in testing. For a country that had flown only foreign jets, the flight was a statement of industrial independence, and it set Soko on a path that led to the Jastreb, the Super Galeb and the Orao.
Training

Solo in eight hours

A pioneer Galeb pilot remembered just how quickly students took to the jet.

Read the full story
Retired Colonel Mile Nežić was one of the two pilots who ferried the first Galebs into service in 1965. Speaking at the 60th-anniversary gathering at Ečka airfield in July 2021, he said students went solo after about eight hours on the Galeb, where around 1966 the older types had taken some thirty hours. Whatever the exact comparison, the point stands: the Galeb was easy to fly well, which is exactly what an air force academy needs from a first jet.
Training

Thirty generations from Zemunik

The Air Force Academy near Zadar ran its jet course on Galebs for a quarter of a century.

Read the full story
The Yugoslav Air Force Academy at Zemunik, outside Zadar on the Dalmatian coast, was the Galeb’s home. Generation after generation of cadets moved from piston trainers onto the Galeb, then on to the Super Galeb and frontline MiG-21s. Serbian accounts credit the type with training more than thirty generations of pilots, and with producing the great majority of Yugoslavia’s military aviators. One Galeb now in the Belgrade museum logged around 6,000 flying hours across some twenty years of service.
Combat

Zadar, 1991

When Yugoslavia broke apart, the trainers went to war over their own training ground.

Read the full story
In the autumn of 1991 fighting erupted around Zadar, the very city whose airfield housed the Air Force Academy. The Yugoslav Air Force pressed its Galebs, with their 12.7 mm guns, bombs and rockets, into ground-attack missions against Croatian forces. It was an unhappy irony: an aircraft built to teach young pilots from every republic now flew against one of those republics. The Academy was evacuated as the Yugoslav People’s Army withdrew, and later in the war Croatia captured three Galebs during Operation Storm in 1995.
Combat

Seen leaving Udbina

UN observers in Croatia logged Galebs on the move in the mid-1990s.

Read the full story
After 1992 Bosnian Serb and Krajina Serb forces kept small numbers of Galebs and Jastrebs flying. Aircraft of the 105th Fighter-Bomber Regiment operated over Bosnia-Herzegovina, and UN personnel reported Galebs departing the Krajina Serb base at Udbina, in breach of the UN ban on military flights. The flights were one reason NATO’s Operation Deny Flight existed, and studies of UN and NATO air power over the former Yugoslavia record the type among the violators.
Combat

Killed on the runway at Misrata

In 2011 a Libyan Galeb became one of the first casualties of the no-fly zone.

Read the full story
Libya had been the Galeb’s biggest export customer, and Qaddafi’s forces still flew them in 2011. On 24 March, an AWACS alerted a French Rafale patrol that a Libyan Galeb was airborne over Misrata in violation of the UN no-fly zone. The jet landed before the Rafales could reach it; the French then destroyed it on the ground with an AASM guided weapon. A French military statement said the strike was made “while the fighter jet of Colonel Gadhafi’s forces had just landed at the military base in Misrata”.
Combat

Mercenaries at Gbadolite

In Zaire’s collapse, a lone Galeb flew for Mobutu with Serbian pilots.

Read the full story
In 1996 and 1997, as the First Congo War closed in on Mobutu Sese Seko, Zaire hired a mercenary air unit staffed largely by Serbian pilots and technicians. Its fleet included one Galeb and several Jastrebs, flown from Gbadolite, Mobutu’s palace town. The unit achieved little. One of its pilots was killed when he clipped a lamp post during a low-level pass, and the aircraft were abandoned as rebel forces advanced in 1997.
Survivor

From Mostar to Texas

Late in the Cold War, Galebs started to appear on the American civil register.

Read the full story
In the late 1980s American warbird dealers bought at least a dozen surplus Galebs from Yugoslavia, among the first ex-Eastern European jets to reach private Western owners. Survivors have since been registered in Texas, Illinois, California, Washington and New York, and others have flown in Australia, New Zealand, Britain, Austria and Slovenia. One, N669M, joined the Air Combat Museum in Springfield, Illinois. For many owners the Galeb offered an affordable, aerobatic military jet with a genuine Cold War pedigree.

The Stars of Novi Sad

Civilian Galebs still fly formation aerobatics in Serbia.

Read the full story
In Serbia a civilian team called The Stars, based at Novi Sad, flies Galebs in formation. The team made its international debut at the Air Borne 2007 show at Rakičan in Slovenia and has since become a fixture of regional air shows, one of the very few places where a Yugoslav-built jet can still be seen performing aerobatics. The Belgrade Aeronautical Museum highlights the team as part of the type’s living legacy.

A seagull in the movies

The Galeb has a minor Hollywood credit.

Read the full story
Civil-registered Galebs flew in the 1992 action film Aces: Iron Eagle III, painted in improvised South American markings to play the drug lord’s air force. It was a brief and slightly absurd screen career for an aircraft designed to teach Yugoslav cadets, but it came from the same source as the warbird boom: Galebs were cheap, available and looked like real military jets because they were.

Service Record

The G-2 Galeb’s record

The Galeb’s main achievement was training: it produced most of Yugoslavia’s military pilots for a quarter of a century. It also flew ground-attack missions in the Yugoslav wars, in Libyan service from the 1980s to the 2011 civil war and briefly in Zaire, though it never claimed an air-to-air victory.
