Cantieri navali Tosi di Taranto

The Cantieri navali Tosi di Taranto (Tosi Shipyard at Taranto) is a defunct Italian shipyard founded in 1914 by engineering company Franco Tosi & C. Between World War I and World War II it specialized in building submarines. The company never really recovered from the devastation from World War II and it was one of the first acquisitions of the newly formed financial holding company, Fincantieri, on 29 December 1959. The shipyard closed on 31 December 1990.
