A guided 76 mm barrage against Kongo

How many OTO Melara 76 mm guns would a modern ship need to defeat a Kongo-class battleship?

The example uses six guns in three twin mounts to argue for a mission kill, without demonstrating that the armored hull would sink.

The example proposes a Type 31 carrying six 76 mm guns in three twin mounts, firing guided Vulcano ammunition. At the assumed firing rate and range, Alex Clarke calculates about 1,440 rounds in two minutes from forty kilometers. He expects the barrage to destroy the superstructure and the equipment needed to direct return fire, producing a mission kill. A participant asks about the effect of the incoming shell weight on stability, but the reply returns to damage and rates of fire without resolving that question. The proposed result is loss of fighting capability, with no demonstration that the armored hull would sink. The fit, ammunition performance, and firing figures belong to the scenario. The reply later switches to a comparison with 18-inch guns, so those return-fire figures should not be read as Kongo's armament.
