The Novi Avion (Serbian Cyrillic:Нови Aвион English: New Aeroplane) was a 4th-generation, supersonic multi-role combat aircraft project of cropped delta-canard configuration. The work was undertaken by the Vazduhoplovno Tehnicki Institut (VTI) (Aeronautical Technical Institute) of Belgrade, the former Yugoslavia's main military-technical institute, but cancelled just before production began in 1991.
