Italian special-attack craft against Malta

Did Italian frogmen or human-torpedo forces attack Malta?

Italian fast and explosive motorboats operated against Malta, but the recollection does not include a comparable diver or human-torpedo attack.

Several Italian special-attack methods are often grouped together. Malta faced fast boats, motor torpedo boats, and explosive MT boats, while the recollection does not include a diver or manned-torpedo attack comparable to Alexandria. The distinction matters because the Regia Marina did not use its most famous special-operation method against every target.
