Orizzonte-class frigates

Orizzonte-class frigates are a class of Italian Navy ships, designed to operate in a multi-mission environment, including anti-submarine warfare, anti-surface warfare, and air defense. The class is based on the Horizon-class frigate design, developed in collaboration with the French Navy and the Italian Navy. The Orizzonte-class frigates are equipped with advanced Aegis Combat System-like capabilities, including the EMPAR phased array radar and the SAAM air defense system, similar to those used on Arleigh Burke-class destroyers and Ticonderoga-class cruisers. The ships are also fitted with Otobreda 76 mm guns, Sylver A50 vertical launch systems, and Twin 324 mm torpedo tubes, similar to those used on La Fayette-class frigates and Formidable-class frigates.

● Introduction

The Orizzonte-class frigates were designed to replace the older Lupo-class frigates and Maestrale-class frigates in the Italian Navy, with the goal of improving the navy's capabilities in anti-submarine warfare and air defense. The class is named after the Italian word for "horizon", reflecting the ships' advanced radar and sensor systems, similar to those used on Oliver Hazard Perry-class frigates and Knox-class frigates. The Orizzonte-class frigates are also designed to operate in a NATO environment, with interoperability with other NATO ships, such as Fletcher-class destroyers and Gearing-class destroyers. The ships have participated in several NATO exercises, including Operation Active Endeavour and Operation Allied Protector, alongside ships like USS Enterprise (CVN-65) and HMS Invincible (R05).

● Design and development

The Orizzonte-class frigates were designed by a consortium of Fincantieri, Orizzonte Sistemi Navali, and Armaris, with the participation of the Italian Navy and the French Navy. The design is based on the Horizon-class frigate concept, which was developed in the 1990s as a joint project between France and Italy. The Orizzonte-class frigates have a length of 153 meters, a beam of 20.3 meters, and a draft of 5.4 meters, similar to Freedom-class littoral combat ships and Independence-class littoral combat ships. The ships are powered by a combined diesel and gas turbine propulsion system, which provides a top speed of over 29 knots, similar to Arleigh Burke-class destroyers and Ticonderoga-class cruisers. The ships are also equipped with advanced stealth features, including a reduced radar cross-section and a low-observable design, similar to Zumwalt-class destroyers and Visby-class corvettes.

● Operational history

The Orizzonte-class frigates have been deployed in several operations, including Operation Enduring Freedom and Operation Iraqi Freedom, alongside ships like USS Nimitz (CVN-68) and HMS Ark Royal (R07). The ships have also participated in NATO exercises, such as Operation Active Endeavour and Operation Allied Protector, with ships like USS Enterprise (CVN-65) and HMS Invincible (R05). In 2011, the Orizzonte-class frigates were deployed to Libya as part of Operation Unified Protector, alongside ships like USS Barry (DDG-52) and FS Forbin (D620). The ships have also been used for humanitarian missions, such as the evacuation of civilians from Libya during the 2011 Libyan civil war, with the help of ships like USNS Comfort (T-AH-20) and HMCS Toronto (FFH 333).

● Ships

in class The Orizzonte-class frigates consist of two ships: Andrea Doria (D 553) and Caio Duilio (D 554). Both ships were built by Fincantieri at their Riva Trigoso shipyard, with the participation of Orizzonte Sistemi Navali and Armaris. The ships were commissioned in 2007 and 2009, respectively, and are based at the Italian Navy's Taranto naval base, alongside ships like Giuseppe Garibaldi (C 551) and Cavour (C 550). The Orizzonte-class frigates are part of the Italian Navy's Fleet Command, which also includes Ammiraglio di Saint Bon-class destroyers and Maestrale-class frigates, as well as ships like USS San Antonio (LPD-17) and HMS Ocean (L12).

● Characteristics

The Orizzonte-class frigates have a displacement of 6,700 tons, a length of 153 meters, and a beam of 20.3 meters, similar to Freedom-class littoral combat ships and Independence-class littoral combat ships. The ships are powered by a combined diesel and gas turbine propulsion system, which provides a top speed of over 29 knots, similar to Arleigh Burke-class destroyers and Ticonderoga-class cruisers. The ships are equipped with advanced sensor systems, including the EMPAR phased array radar and the SAAM air defense system, similar to those used on Aegis Combat System-equipped ships like USS Arleigh Burke (DDG-51) and JS Kongo (DDG-173). The ships are also fitted with Otobreda 76 mm guns, Sylver A50 vertical launch systems, and Twin 324 mm torpedo tubes, similar to those used on La Fayette-class frigates and Formidable-class frigates.

● Upgrades and modernization

The Orizzonte-class frigates are scheduled to undergo a mid-life upgrade, which will include the installation of new radar and sensor systems, as well as the upgrade of the ships' combat management system, similar to the upgrades performed on Arleigh Burke-class destroyers and Ticonderoga-class cruisers. The upgrade will also include the installation of new missile systems, including the Aster 30 surface-to-air missile and the Exocet MM40 anti-ship missile, similar to those used on Horizon-class frigates and FREMM multipurpose frigates. The Orizzonte-class frigates will also receive new electronic warfare systems, including the SLQ-32 electronic warfare system, similar to those used on Oliver Hazard Perry-class frigates and Knox-class frigates. The upgrade is expected to extend the service life of the ships by 10-15 years, allowing them to remain in service until the 2030s, alongside ships like USS Gerald R. Ford (CVN-78) and HMS Queen Elizabeth (R08). Category:Italian Navy ships
