    Default Soko J-22 Orao

    The Soko J-22 Orao (Eagle) is a ground-attack and recconisance aircraft developed as a joint-venture in Yugoslavia and Romania.

    Development and construction

    Soko J-22 Orao, was intended as a replacement for the lightly armed Soko J-1 Jastreb (Hawk), and the ubiquitous Republic F-84G Thunderjet, then in JNA ****nal.

    On May 20 1971, the governments of Romania and Yugoslavia signed an agreement for the formation of YuRom, a joint R&D venture. The program was headed by Dipl. Dr. Engineer Teodor Zanfirescu of Romania and Colonel Vidoje Knezevic of Yugoslavia.

    The aircraft is of a conventional high wing monoplane construction with two Rolls-Royce Viper turbojets provided as primary propulsion. Alhtough originally it was intended for afterburners to be developed and added to the Viper turbojets, there were prolonged difficulties with this project. During 1980s, both countries developed slightly different versions to take advantage of new propulsion technologies then becoming available.

    Flight testing

    The Yugoslav prototype 25002 made its first flight on November 1976 from Batajnica airfield near Belgrade, with Major Vladislav Slavujevic at the controls.

    The third aircraft, numbered 003, a pre-production two-seater version, made it's first flight on July 4, 1977. But was lost almost a year later due to tail flutter problems.

    However, construction continued, and the first batches of pre-production machines were delivered on 1978 to the Air Force Aircraft Testing Facility in Belgrade, with serial production being set-up in Mostar, Bosnia and Herzegovina.

    Operational history

    Serbian machines saw combat against NATO in 1999. During the campaign, Serbian sources claim, a J-22 shot down a Tomahawk cruise missile. This representing the only succesfully air-to-air action by an Orao. The war ended with most Orao's successfully surviving the bombing campaign.

    Variants

    Orao 1 - initial production version, without afterburners. Lack of performance limited role to tactical reconnaissance - later re-designated IJ-22 (Izvidyach Yurishny - reconnaissance attack)
    NJ-22 - two-seat trainer version of the Orao 1. (Nastahvny Yurishny - trainer attack)
    Orao 2, also known as J-22(M) - refined version with afterburner, enlarged fuel tanks, HUD, ejection seat, and LERx.
    Orao 2D, also known as NJ-22(M) - two-seat trainer version of Orao 2

    Dalleer:

    The irony is that you just said that the 'Eagle' (Orao = Eagle) must have been a real hawk back in the day.



    I hope I'm not the only one who finds that humorous.

    Well even as recently as in 1999 during the NATO airwar against Yugoslavia the aircraft was in action, flying fighter-bomber and recon missions, none were intercepted by NATO airforces, even as they were supposedly incontrol of the airspace.

    Tells alot about the quality of mission planning and about the low flying skills and of the knowledge of the terrain that local pilots / airforce had.

    The story goes that romanian inteligence in britain or germany not sure,...got somehow incomplete blueprints of some british designed plane(i think it was lower part of the plain where the landing gear is etc,...) and then romania offered yugoslavia to try to produce plain at 50/50 costs but it wasnt posible because they were missing many details so at the end they(yugos) bought plan from the brits and built upper part of the plane on it themselfes.

    Interesting story shadower, it makes sense 'cause Orao looks almost like british Jaguar(landing gear, wings, whole bottom part is almost the same):

    That's a big bull**** dude...
    The iar-93 was romanian/yugo design ... Not a slant of British design in them.. The Vipers engine where the only engines that where allow by the Brits to be exported. As you know there was an Embargo against WP countries. Only Engines under 20KN where allow to be exported and licenced.

    The Iar-95 was to be the supersonique fighter that needed and engine ...We wanted the RR Spey(the engine was used in Romanian produced BAC-1-11) they say no...we asked the russians and then Chinnese (they where producing the Mig21 engines.) they said No..the plane never get beyond scale model.

    The yugo guy who worked in yugo institute on developing this plane told a story on the another forum where yugo pilots hang around.
