Battle of Cape Matapan
The first prototypes were designed by navy technicians Ugo Tiberio, Nello Carrara and Alfeo Brandimarte in the period 1936–1937. The project was stalled due to budget cuts until 1941, when interest was revived soon after the Italian navy suffered a series of heavy setbacks in night actions against the radar-equipped units of the Royal Navy, especially that of the Battle of Cape Matapan.
