Hawk is a fast moving fighter jet that is designed for eliminating multiple and/or heavy air units.
It has little problems with scattered T1 air defenses. Always put your fighters on patrol in front of your base, so they attack any aircraft moving in the vicinity. Send fighters with your bombing runs to disable opponent's fighter wall before your bombers come to deliver the final blow.
Its stealthy attribute makes it invisible to radars.
Your enemy never knows how many you have without scouting. A bit slower but and a little more effective than its CORE counterpart.
