It had a 20mm cannon that retracted up into the fuselage, a much more advanced version than found on the Cobra with twice the rate of fire. It could carry 6 hellfire internally or 24 rockets or 12 stinger (6 hardpoints) plus 8 more hardpoints if the external wings were added on but then you lost the stealth ability.
It was all composite using the latest stealth technologies, had a cruise airspeed of 175 knots and was fully aerobatic.
