HVAR and RP-3 rockets threatened warship upperworks

Neither rocket needed to penetrate a battleship belt to suppress anti-aircraft guns, damage sensors, and make a ship vulnerable to follow-on attack.

Question

Which was more effective against ships, the American HVAR or the British RP-3?

Short answer

Both were dangerous because they could devastate upperworks and anti-aircraft positions, weakening a ship for later attacks even without penetrating its main armour.

Notes

Both the American HVAR and British RP-3 were dangerous naval-attack weapons, making a universal winner difficult to choose. Their explosive and kinetic effect could wreck exposed weapons, directors, radar, bridge spaces, and crews. That damage reduces a ship's ability to defend itself even when the main armour remains intact. Repeated rocket attacks therefore create opportunities for bombs, torpedoes, or later aircraft to finish the target.
