Saettia 920
The “Saettia 920” is an experimental prototype of a Missile Motorgun, built by Fincantieri as a DA-360T demonstration unit. The company’s intention was to offer it to the Italian Navy and foreign navies, but without finding buyers, nevertheless the goodness of the project remains. The “Saettia 920” for its equipment can be considered as a “small Corvette” in fact its equipment is very respectable, the propulsion department consists of four diesel engines MTU 16V538 TB93 of 17600 hp, and three diesel electric generators Isotta Fraschini ID38 SS6V, all this allows it to reach the maximum speed of 40 knots (74 km/h). The armament is very respectable, it consists of a compact OtoMelara 76/62mm cannon, positioned at the bow, a compact OtoMelara Cannon 30/82mm twin cannon is installed at the stern, the armament is completed by two pairs of launchers for OtoMat Mk2 SSM, for a total of four anti-ship missiles. The electronic equipment consists of a RADAR for navigation Selenia RAN-11 L/X, the RADAR for air and maritime surveillance is a Selenia Orion RTN-10X, the weapons control system is an Elsag NA 21, there is also an ELT/521 jammer, there are also two Breda 6105 - 105mm Chaff/Decoy RL. The “Saettia 920” was built in the Muggiano shipyards, laid down in June 1984, launched in December of the same year and completed in December 1985. At the beginning of the nineties it was withdrawn to be subsequently acquired by the Port Authorities Corps after being modified by Fincantieri itself according to the specifications of the Coast Guard.
