The Soko G2 Galeb (English: Seagull) is a Yugoslav single engine, two-seater jet trainer and light ground-attack aircraft. The G2 was developed during the 1950s by the Aeronautical Technical Institute at Žarkovo as a replacement for the Lockheed T-33 in service with the Yugoslav Air Force (Serbo-Croatian Latin: Ratno vazduhoplovstvo i protivvazdušna odbrana – RV i PVO). Production started in 1965 at the Soko aircraft factory in Mostar, and ended in 1985 with 248 aircraft delivered. The G2 had the distinction of being the first mass-produced jet aircraft in socialist Yugoslavia. It also served as a basis for the single-seat ground-attack J-21 Jastreb. The RV i PVO took delivery of 128 aircraft that were used by the Air Force Academy for training new pilots. The second largest operator of the Galeb was Libya, which acquired over 100 aircraft during the 1970s. A small number were also acquired by Zaire, Zambia and Indonesia. During the breakup of Yugoslavia, the Galebs were used for ground attack sorties throughout Croatia and Bosnia and Herzegovina. By 1992, RV i PVO G-2s relocated to Serbia and Montenegro where they operated with the Air Force of the new FR Yugoslavia. The aircraft remained in service until 1999 when the majority of them were destroyed on ground during the NATO bombing of Yugoslavia. The Libyan Air Force's G2s were used during the Libyan Civil War by Gaddafi forces, with an unknown number surviving the war and being reported in service as late as 2013. A single aircraft remains in service with the Technical Test Center of the Serbian Armed Forces. A number of aircraft are still flown by civilians as warbirds, including the private aerobatic team "Stars" from Novi Sad. John Travolta is listed as a private owner, and the hangar photo below (177) was taken at Lilydale in 2011. For details of development, design, operational history and variants, click here.
