In 2015, a consortium composed of Avioane Craiova, and announced that an enhanced version of the IAR 99 called IAR 99 TD is under development. A single airframe will be built with a new avionics suite, a engine and radar. The Leonardo Vixen 500E radar was chosen and requires lengthening the nose by 900mm. A new engine which supports computer control is required to replace the 1951 designed Rolls Royce Viper. This in turn will need a twice as big air intake. A prototype is expected to be completed by 2022.
