The 112 fighter aircraft in the Fleet are all making a defensive screen, the large number of ships in the fleet can easily detect the B-2's at a range of about 20 Km, because of multiple radar arrays scanning from multiple angles, along with the exhaust from the aircraft. the radar gives an aproxoment location and 24 fighters quickly intercept, after visual confirmation they each fire four AIM-9 missiles and give the B-2's a burst with cannon rounds, the ships also light up the sky with 100 mm, 76 mm, 37 mm, and 30 mm fire. this is all before the B-2 is within bomb range.
