A stretched fighter, mini-bomber, designated for deep strike missions similar in scope to the F-111 Aardvark and the F-117 Night-Hawk, like a stealth F-15E Strike Eagle. The are designed to get to targets fast, out in the middle of nowhere. They are bomb trucks that can protect themselves from enemy fighters with air to air defenses. They fit in a sweet spot of better protected than a standard bomber, and carry more ordnance than a fighter.
The tailless design gives it greater stealth. The delta-wing design gives the jet a large wing area, enabling super-cruise and greater range. The co-pilot, conducts hard and electronic attacks or drone operation. A backwards facing radar between the engines targets would be aggressors.
