MM San Giorgio D562 (1965)

After the end of the Second World War, Italy was struggling with the reconstruction of its Armed Forces, due to its geographical position in the middle of the Mediterranean Sea, especially the Navy represented (and represents) a strategic component. So they tried to use all the options available to speed up the times, one of these was the modernization of two light cruisers (Capitani Romani Class) of the Second World War, the “Pompeo Magno” and the “Giulio Germanico”. Thus a new Class of destroyers was born, the “San Giorgio” composed of the “San Giorgio D562” and “San Marco D563”. The “San Giorgio” was the modernization of the “Pompeo Magno”, the works began in the Genoa shipyard in 1953 and ended in 1955, in the same year the “San Giorgio” entered service with the optical distinctive D562, this first modernization of the “San Giorgio” was identical to its twin “San Marco”. In 1963 it was decided to transform the “San Giorgio” into a Training Ship and it was transferred to the Arsenal of La Spezia, where modification works began to adapt the Unit to the new task to be performed, this new modernization ended in January 1965. These new modifications also concerned the armament, in fact the two pieces of the second bow turret of 127/38mm and all the pieces of 40/56mm were eliminated to make room for three guns of 76/62mm type MMI in single installations, the old anti-submarine systems were also eliminated and replaced by six torpedo tubes of 324 mm in two triple systems for the launch of wire-guided torpedoes. The most important modifications were applied to the propulsion system, the four boilers and the two turbines were removed and replaced by a CODAG type system consisting of four FIAT-Tosi diesel engines of 4,000 hp each and two Tosi-Metrovick G6 gas turbines of 7,600 HP each. The new propulsion system allowed the unit to reach a maximum speed of 28 knots (52 km/h). The electronic systems were also modified, a new SPQ-2 navigation RADAR, three Galileo “Orion 3” fire control units were added, the Sonar was also replaced with an Echo Sounder, while the air surveillance RADAR remained the AN/SPS-6, as was the RADAR for fire control Mk 25. Despite the role of Training Ship, which the “San Giorgio” played in the summer season, during the remaining months of the year it continued to carry out normal team activity. After 25 years of intense activity, the “San Giorgio” was decommissioned in 1980.
