I got involved in a long forum fight over a B-2-versus-carrier claim.
The fish-heads stoutly maintained that the use of tactics, decoys and EMCON would prevent B-2s from finding them using LPI radar. They were probably right in that you'd have needed some offboard cueing (TacSats or HALE UAVs would be the way to do that now.)
We also had an existing-weapon constraint in the discussion (I'd have used ultra-LO GPS-plus-update glide bombs).
However, a long-range, long-endurance LO platform poses a hell of a problem to carriers. The bad guys have not got one. Yet.
