one of my favorite designs, really nice work, it's very applicable and stealthy indeed, i believe if it's ever build it will have less radar signature than F-22 due to it's sharp delta shape and you toke care of the details avoiding all 90 degree angles with the direction of movement. nice work.
allow me to add one more suggestion to this design, is to add two extra medium missle bays 2.5~3 meters long at the intakes to maximize the armament capacity, also all bays can be used for extra optional fuel tanks.
you already have the capacity of 4 long range BVR missiles which can be replaced by 8 close range compat missiles or 2 major strike bombs, the maximum length of a BVR missile is about 4.8 meters which means that those bays you have is about 5 meters each making the total length of this aircraft is about 20 meters max, quiet a big girl, like the big russian sukhoies (they 22 meters max).
i have respect to all delta wing / tailless designers, i'm new to the graphics world, but i have alot of pencil designs that i will digitize soon.
really beautiful, nice work
Two things to nitpick:
1) It should probably be a little fatter in the middle to leave enough room for fuel storage. With the large engines, weapon bays and air intake ducts, there isn't a lot of internal volume left for the fuel (no, not the wings, those are too thin), which powerful supercruise engines need a lot of.
2) The number 21 is already taken. In the 1980s, the US leased several IAI Kfir fighters from Israel and designated them the F-21 Lion (they were used in the Red Flag and Top Gun programs as aggressor aircraft). This would have to be at least F/A-24 or F/A-25*
*Further sub-nitpick: I don't see a bay door covering a tail hook, so it doesn't look like this is a Navy aircraft. The Air Force doesn't really care for the "F/A" designation, they want to call their aircraft "F" for "fighter" because it sounds more macho that way.
