Taranto damaged the Italian battle fleet without permanently eliminating it. Cunningham had concentrated a large capital-ship force and hoped the Italians would come out to attack the carrier or answer British incursions. Their losses instead discouraged a sortie, denying him the night or early-morning surface battle he wanted. The damaged ships were not all permanently lost, so Italy retained a fleet that could recover. A second carrier in the strike might have inflicted enough additional damage to leave Italy with far fewer capital ships for the rest of the war.

Why Taranto did not produce Cunningham's decisive surface battle
Taranto's damage discouraged an Italian sortie while leaving ships available after repair, frustrating the hope for a decisive follow-up battle.
