This is the Tamiya F-16CJ Block 50, in the markings of the Commander 5th Air Force, Misawa Air Base Japan, 2010. This one was built entirely out of the box.
Tamiya initially released this kit without the weapons, and it was not received well by the modeling community. The later boxing included the full load of external stores missing the first time around. The parts are very finely detailed. Care has been taken to minimize the size of the sprue gates and to locate them on hidden surfaces whenever possible. You really get the feeling that the designers are guys who build models themselves. If you’ve seen a Tamiya Zero you will get the same appreciation for the engineering with this kit.
