After the war, "MAS-15" was installed in the Monument to Vittorio Emanuele II as part of the "Museo del Risorgimento" in Rome for the torpedo boat's role in the sinking of "Szent István". The anniversary of the sinking, 10 June, has been celebrated by the "Regia Marina", and its successor, the "Marina Militare", as the official Italian Navy Day (). After "Tegetthoff" was dismantled, one of her anchors was placed on display at the Monument to Italian Sailors at Brindisi, where it can still be found.
