During the Yugoslav Wars, RV i PVO G-4s carried out ground-attack sorties, a total of four were recorded as having been lost to enemy air defences.

During 1992, the remaining aircraft were relocated to Serbia and Montenegro where they entered service with the Air Force of the newly formed FR Yugoslavia.

According to aviation periodical Flight International, the Super Galeb showed unmistakable lineage from the earlier G-2, sharing the same British-sourced Rolls-Royce Viper turbojet engine, albeit uprated for greater performance.

[4] The aircraft is fitted with a short nose cone, rounded fuselage, conventional empennage, semi-circular air intakes, vertical tailfin, rudder, ailerons, horizontal stabilisers and fuel tanks at the square tips.

[2] For combat missions, the Super Galeb can be outfitted with a centreline-mounted gun pod containing a twin-barrel 23mm Gryazev-Shipunov GSh-23L cannon with up to 200 rounds.

In addition, four hard points are installed beneath the wings, the inboard pair having a 770-pound (350 kg) capacity while the outboard have a 550-pound (250 kg) capacity; these can carry a variety of Western and Eastern European armaments and equipment; the inboard pylons are plumbed for 70 gallon external fuel tanks, a locally developed reconnaissance pod was also under development at one stage.

Reportedly, this programme primarily revolved around the integration of new air-to-air and air-to-ground missiles, as well as an improved aiming capability, adjustments to raise engine reliability, and enhanced electronics.

Since then, a group of Serbian aviation enthusiasts have assembled a new display team, but have equipped it with older Soko G-2 Galebs that had been previously withdrawn during the 1980s.

Intended to be re-designated G4-MD, the envisioned upgrade programme, which largely revolves around new avionics for improved navigation, greater ease of control, and integrate new combat systems, is reportedly set to extend the type's service life through to the 2030s.
