Soko G.4 Super Galeb
Designed to replace the T-33 and the earlier G.2A Galeb in Jugoslavian Air Force service, this two-seat basic trainer/light strike aircraft has swept wings and all-swept tail surfaces, the tailplane having pronounced anhedral, and stepped tandem seating. Its performance is improved by the introduction of a 17.8kN Rolls-Royce Viper turbojet.
The first of two prototypes was flown on 17 July 1978 and the first of six pre-production aircraft on 17 December 1980. These and the first prototype were designated G-4 PPP, and had fixed tailplanes with inset elevators and no anhedral.
Production examples (and the second prototype) were designated G-4 and featured an all-moving anhedral tailplane and comprehensive avionics improvements. Armament includes a detachable underfuselage 23mm cannon pod, and a variety of stores on four underwing hardpoints. A Ferranti D282 gyro gunsight is standard equip-ment.
The G-4 was been ordered in large numbers for the Yugoslav air force. They were delivered to the Air Academy at Zemunik (later relocated to Udbina) and to advanced flying schools at Pula and Totograd. The academy fleet includes the 'Letece Zvezde' (Flying Stars) formation display team, whose aircraft are painted in a red, white and blue colour scheme.
Twelve G-4s, in two batches of six, were delivered to Myanmar in 1991 and 1992.
A ground-attack trainer, with advanced avionics, an upgraded nav/attack system, and wingtip missile launch rails was developed under the designation G-4M, but no prototype has flown. A similar single-seat derivative designated G-5 was also under development.
The UTVA factory was heavily bombarded in 1999 and certain parts of it were still off limits due to the unexploded ordnance in 2012. All five original lasta 95 prototypes were destroyed in the factory and the only existing Supergaleb G4MD prototype was lightly damaged.
