Baionetta corvette

Baionetta corvette

In the last months of 1940 the Regia Marina understood that the escort of the traffic directed to overseas started to present difficulties that had not been foreseen and which seemed hard to overcome. Besides, the scarcity of available naphtha advised against a too prolonged utilization of the units, above a certain tonnage, for missions of escort to convoys. The threat of the British Fleet which could interrupt the flow of supplies forced, however, to use as well large units, which was a high risk, considering that the strong fuel consumption would have led, sooner or later, to the immobilization of the Fleet.

It was decided then to build units of the same type than the British corvettes, adapted for escort, particularly antisubmarine, in such a way that they were built quickly, with a reduced initial cost and with good structural and nautical qualities. The studies started in the first months of 1941, and the 3rd October 1942 the first corvette, the Gabbiano, entered service with the Regia Marina. Of the other 59, all of them started, only 29 could be delivered to the Regia Marina due to the arrival of the Armistice.

The units in question, studied to operate as "guard dogs" quickly moving within "herds" of merchant ships that advanced at a maximum speed of 11-12 knots, had a very interesting engine system, constituted by two Diesel in two axes, with a total power of 3500 horsepower, which in actions of antisubmarine hunt gave way to two silent electric motors, of 75 horsepower each, fed by accumulators and able to move the ship at a maximum speed of 7 knots without betraying her presence to the hydrophones of the attacked submarine. The units had as well ecogoniometric systems and the installation of a demagnetization system allowed to face with sufficient safety the danger of magnetic mines.

Overall they showed themselves as good units and many of them had a very long operative life after the war. Among these the Baionetta, delivered to the Regia Marina the 28th July 1943, which was decommissioned by the Marina Militare the 1st January 1971 after long years of training service. In 1977 was still operative in the role of pilot ship the corvette Ape, modified as incursion support ship.
