A Gloriana associated with Corvus illustrates a weakness in combining stealth and protection. Its concealment is described as effective against all but the strongest psykers. Using it required shutting down the shields, and the ship could not switch back quickly enough during combat. That incompatibility is identified as the reason for its eventual destruction in the fictional account.
