Not a chance. The B2 is a manned platform. It’s also quite an old one which would require a huge program to create an autonomous capability. The B2’s successor (the B21) is coming soonish so such a program would have no support. Right now, autonomous military aircraft are mostly being considered for support roles like tankers with future projects of “loyal wingman” fighters to fly alongside a manned fighter. A deep, precision strike from an untested technology would never fly.
