Variants:

G-4 Super Galeb: Designed to replace the G-2 Galeb and Lockheed T-33 in Yugoslav service, the Super Galeb (super seagull) bears no more relationship to the G-2 Galeb than an identity of role, being and altogether more advanced machine with marked conceptual similarities to the BAe Hawk. The type was first flown in July 1978 as the G-4PPP prototype, which, with the following six pre- production aircraft, had a straight tailplane with conventional inset elevators. However, the G-4 production variant that entered in service in 1983 has a slab tailplane of distinct anhedral. The type offers a modest light attack facility in addition to the standard training role, and this capability is being expanded under an improvement program revealed in 1990 but interrupted by civil war as the former Yugoslavia fragments into a number of smaller states. The improvement program is designed to upgrade engine performance under icing conditions, update the electrical and electronic (including nav/attack) systems, and enhance weapon capability for missiles such as the R-60 (AA-8 “Aphid”) and R-73 (AA-11 “Archer”) short range AAMs, and Kh-23 (AS-7 “Kerry”) and AS-9 “Kyle” ASMs.



G-4M Super Galeb: The program for this upgraded Super Galeb has revived to provide a more capable type in the armament training and light attack roles. The variant’s improvements stem from the use of more advanced avionics and higher-rated hardpoints complemented by a missile rail at each wing tip. The avionics include a Zrak ENP-MG4 HUD, Rudi Cajavec ENS-MG4 electronic sight, gyro platform, multi function displays, and optional chaff/flare dispensers. The inner and outer hardpoints are each rated at 500 and 350 kg respectively for a maximum disposable load of 1800 kg. In other respect, the G-4M differs from the G-4 in details such as span of 10.05 m excluding tip-mounted AAMs or 10.31 m including tip-mounted AAMs, aspect ratio of 5.18, empty equipped weight of 3403 kg without missile rails and 3435 kg with missile rails, internal fuel weight of 1376 kg supplemental by up to 925 kg of external fuel in one 449 liter and two 368 liter drop tanks, normal take-off weight of 4971 kg as a trainer, maximum take-off weight of 6400 kg as an attack warplane, maximum level speed ‘clean’ of 865 km/h at 10000 m and 900 km/h at 4000 m, ferry range of 2900 km with drop tanks; range of 1800 km with standard fuel reducing to 1200 km with cannon pack, four BL755 cluster bombs and two AAMs, maximum rate of climb at sea level of 1800 m per minute, and service ceiling of 12500 m.

There is always confusion, because different sources report different numbers.
