What aircraft rockets could do to an armored warship

How effective were air-launched RP-3 rockets against an armored warship?

They were limited against armor but useful against exposed equipment and crews, and they could distract defenses during a mixed attack.

The RP-3 was of limited use against a warship's armor. Rockets could still damage exposed anti-aircraft positions, radios, and masts, start fires, produce smoke, and force defenders to divide their attention. In a combined strike, that disruption could help Swordfish or other attackers reach the target. Their value came from suppressing crews and damaging systems in coordination with other aircraft.
