Thanks for the replies guys.
I understand the issues now. I am pushing my creation to be an affordable personal jet plane for the civilian market. I was just interested if the Military is an option.
P.S. My jet is not to compete with Jet trainers such as the Hawk, Yak-130 etc etc. It was to replace basic single-engine props. Its weight is less than a ton. But regardless, I understand the problems associated with Military use of such an aircraft.
