They can't. The only chance they have at detecting them is with low frequency early warning radars, which can't provide firing solutions. Then they've gotta find the B2s with more accurate ground based systems or more likely scramble fighters who will then meet the superior F-22 and F-35 escorts, all while JASSMs, Tomahawks and AARGM-ERs are giving C2 and the AD something to think about.
