The Italian Minisub Maiale (or "Pig") was the direct inspiration for the British Chariot series of minisubs. It is a modified electric torpedo with a detachable warhead. Three were carried by the Italian submarine Sciré to the Egyptian port of Alexandria on December 3, 1941. The 3 Maiales and their 6 crew members proceeded into the harbor and successfully sank the British battleships HMS Queen Elisabeth, Valiant, and a British tanker. Their crews survived and were captured, and as a result of their examination of the recovered Maiales and the success of the mission the British developed their own version, the Chariot. This particular Maiale is an SSB (Siluro San Bartolomeo) version - the last of the Mailale series and was built sometime in 1943. This version more or less encased the divers providing better security and less hydrodynamic drag and better range. Italy's surrender in 1943 saw the SSB Maiales fall into allied hands and this example did not see action. 80 Mailale's were produced between 1940 and 1943.
