I have always considered the Tazarv/Dorna jet trainer the true representation of Iran's Aviation industry..A completed design, plenty of prototypes, cheap construction, available engine, but yet no production. I have never quite understood why this design hasnt entered production. It's airframe is predominately Fiberglass which is cheaper to build and assemble than traditional aluminum airframe...Its not like the engine isnt available (one of the problems with the Shafagh)...Lack of funds has always been a big problem with Iran's military aviation industry, but the Tazarv is supposely quite cheap (claimed to be $2million apiece), so building a small fleet over say a 5 year period shouldnt very expensive (say 5 aircraft a year, $10 million per year)..I just dont see the logic. Thoughts?
