Cacciatorpediniere Classe Navigatori serie 2

The Navigatori class in 1940
Navigatori class - Second Series

This page would not be the same without the immense support of Eduardo Beck. During the war his father served as medical assistant in the Antonio Pigafetta, one of the ships of the Navigatori class.

Eduardo Beck is the responsible of one of the best and most complete page about the Antonio Pigafetta; in the Regia Marina Italiana section published in Wikipedia, in the Italian language section; he makes an impressive work which shows all his acknowledgement about their father’s ship.

I published this site at the end of 2007. One of the first persons to contact with me was Eduardo Beck; he was profoundly interested on my work and he also showed me how amazingly he was working on the Pigafetta. He transmits me all his collaboration together with significant and profuse material about the Navigatori class.

The rebuilt of 1938 - 1940
as Navigatori second series

On 1938 was decided to modifiy substantially the hull of the Navigatori class to solve definitively the stability and sea keeping deficiencies of the class. The first unit to refit was the Vivaldi; she become the model for the conversion of the other units. The hull was one more meter longer; the freeboard increased and the shape of the bow was modified to solve the definitively and sea keeping problems. She was also near one meter beamer with the incorporation of bulge-like supplements in both sides of the hull’s central part.

After the finalization of Vivaldi works on 1938 all the units remaining were refitted, but on a little different basis; they were 3.5 meter longer with a more pronounced stem. At the beginning of the war there were ten units modified but the two others, the Da Recco and the Usodimare were still unmodified an then their modifications were cancelled definitively.

Because the refitted units were beamer and heavier they were slower, between 28 to 30 knots thus they were not totally suited to Fleet escort duties.

They fought in the World War Two, but suffered heavy losses during the conflict. Only one vessel survived, six ships were lost against other ships by gunfire in the escort duty.

When the war begun all the class was employed initially as Fleet destroyers, but promptly they were transferred to escort duties in the convoys transporting the troops and supplies to the North African Theatre of War. Because their speed was lowered to 28 to 30 knots at high seas, they were not totally suited to Fleet escort duties as the new faster Maestrale, Oriani and Soldati classes were.

In the year of 1942 after appalling losses in the convoy escort duties, all survivors were refitted and received new and better anti aircraft armament, disembarking the after torpedo launcher to give space for a new structure for two Breda 37/54 singles. The first units ending the refit received also German or Italian radar equipment. They also received better anti submarine warfare equipment (ASW).
