OTO Melara 76mm - Super Rapid Fire Naval Gun

The OTO Melara 76 mm Super Rapid Fire Naval Gun is a naval gun built and designed by the Italian defence company Oto Melara. It is based on the Oto Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales. The system is compact enough to be installed on relatively small warships. Its high rate of fire and availability of range of ammunition make it capable for short-range anti-missile point defence, anti-aircraft, anti-surface, and ground support. Ammunition includes armour-piercing, incendiary, directed fragmentation effects, and a guided round marketed as capable of destroying manoeuvering anti-ship missiles. A stealth cupola is now offered. Other specifications Cooling: sea water—fresh water for flushing Electrical Power supply : 440 V, 3-phase, 60 Hz, main circuit; 115 V, 1-phase, 400 Hz, servo and synchro network Variants : Super Rapid Developed in the early 1980s (and sometimes called the "Super Rapido"), this variant is the up-to-date development of rapid fire Italian 76 mm naval cannons, capable of firing an increased 120 rounds per minute. The Super Rapid's higher rate of fire was achieved by designing a faster feed system. Strales system These new improvements led to the Italian Navy preferring the Super Rapido with Strales System and DART ammunition to the Fast Forty 40 mm CIWS, in the anti-missile defence role, being capable of countering several subsonic missiles up to 8,000 meters away. Ammunition To provide multiple roles for the gun, OTO provides the user with wide ranges of specialised ammunition: HE standard (all models): weight 6.296 kg, range 16 km, effective 8 km (4 km vs. air targets at 85°) MOM: developed by OTO (Multirole OTO Munition) PFF: anti-missile projectile, with proximity fuze and tungsten balls embedded in the shell for defined fragmentation effect SAPOM: 6.35 kg (0.46 kg HE), range 16 km (SAPOMER: 20 km) semi-armoured piercing DART: guided projectile for anti-aircraft manoeuvring targets VULCANO: 5 kg, guided projectile with a maximum range around 40 km (it is a smaller version of the 127 mm Vulcano) Fuzes There have been many developments in the fuzes, essential to shoot down low-flying missiles. The best fuze developed for the 76/62 guns is arguably the 3A-Plus programmable multi-role fuze, manufactured by Oto Melara and Simmel Difesa, introduced in the early 2000s. This fuze requires the installation of a fuze programmer in the mount. DART Since the 1980s efforts were made for development of guided 76 mm ammunition, but this was not achieved until recently. The first such ammunition was the CCS (Course Corrected Shell), also known as CORRETTO; a joint program of OTO and British Aerospace. Work started in 1985. The projectile had several small rockets in order to deviate the trajectory. Radio commands were sent from the ship FCS. The FCS did not know the exact position of the projectile, only that of the target. This system was too complex and unreliable, so OTO studied another development in order to obtain a real 'guided ammunition'. VULCANO The more recent development is the VULCANO 76 ammunition system. Basically, it is a scaled down version of the 127–155 mm Vulcano family of extended-range projectiles developed by Oto Melara; guided by Inertial Navigation System and Global Positioning Systems, it is capable of hitting targets twice the distance of normal 76 mm gun ammunition.
