Italian Navy

After the end of hostilities, the Regia Marina – which at the beginning of the war was the fourth largest navy in the world, with a mix of modernised and new battleships – started a long and complex rebuilding process.

However, a large number of its naval units had survived the war, albeit in a low efficiency state, which was due to the conflict and the age of many vessels.

Apart from territorial and material losses, also the following restrictions were imposed: The treaty also ordered Italy to put the following ships at the disposals of the victorious nations United States, Soviet Union, Great Britain, France, Greece, Yugoslavia and Albania as war compensation: Great changes in the international political situation, which were developing into the Cold War, convinced the United Kingdom and United States to discontinue the transfer of Italy's capital ships as war reparations.

The cruisers Attilio Regolo and Scipione Africano became the French Chateaurenault and Guichen, while Eugenio di Savoia became the Greek Elli.

The US government in Washington wished to keep its own installations on the Italian Peninsula and relaxed the Treaty restrictions by including Italy in the Mutual Defense Assistance Programme (MDAP).

The shield's quarters refer to the four Medieval Italian Maritime Republics: The coat of arms is surmounted by a golden crown, which distinguishes military vessels from those of the merchant navy.

The crown, corona rostrata, was proposed in 1939 as a conjectural link to the Roman navy by Admiral Domenico Cavagnari, then a member of the Chamber of Fasces and Corporations in the Fascist government.

A further difference is that St. Mark's lion, symbolising the Republic of Venice, does not hold the gospel in its paw (as it does on the civil ensign, where the book is open at the words "Pax tibi Marce, evangelista meus", meaning "peace to you, Mark, my evangelist") and is wielding a sword instead: such an image is consistent with the pictorial tradition from Venetian history, in which the book is shown open during peacetime and closed during wartime.
