The B-2 bomber can carry up to eighty 500 lb (230 kg) class JDAM “smart” bombs, or sixteen 2,400 lb (1,100 kg) B83 nuclear bombs.
It can deliver its full payload in a single pass and uses an advanced GPS Aided Targeting System (GATS) complete with a passive electronically scanned array APQ-181 radar to correct GPS errors of targets, in order to achieve greater accuracy than laser-guided dumb bombs.
Thank you Mack from Future Weapons.
