The Lerici class is a class of minehunters constructed by Intermarine SpA and owned and operated by the Italian Navy . The class incorporates two subclasses: the first four ships are referred to specifically as the first series of the Lerici class, while eight more ships produced to a slightly modified design are known as "second series Lerici s" or as the Gaeta class .

68-783: A contract was signed with Intermarine to build three mine countermeasures vessels (initially referred to as the MCMV 2010 class, then as the MITO class). The MITOs are based on the Huon class design, but with a redesigned superstructure. The six Ganggyeong - ( Swallow -) class ships of the Republic of Korea Navy are an un licensed derivative of the Lerici class. Constructed by the Kangnam Shipbuilding Corporation,
102-445: A draught of 2.6 metres (8 ft 6 in). The ships have a maximum speed of 14 knots (26 km/h; 16 mph), provided by a single diesel engine (GMT BL.230-8M for 1,600 hp; 1,200 kW) connected to an electric engine (1,985 hp; 1,480 kW) with a variable-pitch propeller. This speed is reduced to 6 knots (11 km/h; 6.9 mph) for mine-warfare operations; three active rudders (small propellers mounted in
136-499: A draught of 2.9 metres (9 ft 6 in). The ships are fitted with two diesel motors driving two Voith Schneider Propellers ; these cycloidal propellers eliminate the need for the aft two active rudders. The ships use a Raytheon/Thomson Sintra SQQ-32 VDS sonar for minehunting, and Alliant SLQ-48 remote vehicles for mine disposal. The ships normally carry a crew of 51, including four officers, and are armed with two 12.7-millimetre (0.50 in) machine guns. Upon entering service,
170-572: A draught of 3 metres (9.8 ft). Main propulsion is a single Fincantieri GMT BL230-BN diesel motor, which provides 1,985 brake horsepower (1,480 kW) to a single controllable-pitch propeller , allowing the ship to reach 14 knots (26 km/h; 16 mph). Maximum range is 1,600 nautical miles (3,000 km; 1,800 mi) at 12 knots (22 km/h; 14 mph), and endurance is 19 days. The standard ship's company consists of 6 officers and 34 sailors, with accommodation for 9 additional (typically trainees or clearance divers ). The main armament

238-543: A maximum speed of 6 knots (11 km/h; 6.9 mph): two are located at the stern, while the third is sited behind the variable-depth sonar. Mines are located with the minehunting sonar, and can be disposed of by the vessel's two Double Eagle mine disposal vehicles , the Oropesa mechanical sweep, the Mini-Dyad magnetic influence sweep, or the towed AMASS influence sweep (which is not always carried). To prevent damage if

306-541: A separate class of ships. The eight ships of the Second Series Lerici class, more commonly known as the Gaeta class, were all launched in the early 1990s, and were commissioned by May 1996. The Gaeta class is almost identical to the Lerici class: the main structural differences between the ships are that displacement of the latter is 77 tons greater, the hull is 2.5 metres (8.2 ft) longer, and

The ships have a range of 1,500 nautical miles (2,800 km; 1,700 mi) at operational speed. Each ship has a standard complement of 47, made up of 4 officers, 7 clearance divers , and 36 ratings . They are equipped with one hyperbaric chamber , one mechanical minesweeper system Oropesa Mk4, two ROV Whitehead-Riva Calzoni MIN-77 (then replaced by one ROV Gaymarine Pluto GIGAS ) and Gaymarine Pluto , remote-operated submersibles for mine investigation and clearance, and VDS FIAR SQQ-14 (IT) sonar.

The Lerici class design has been successfully exported to Algeria, Australia, Finland, Malaysia, Nigeria, the United States, Thailand and Taiwan. However, an inflexible export policy and demands by Intermarine that all ships be built in Italy are believed to have prevented wider sales. These restrictions were lessened in

The hull of the first ship, HMAS Huon was constructed by the Intermarine shipyard in Sarzana, Italy, then was sent to Australia in 1995 for fitting out at ADI's shipyard in Newcastle, New South Wales. ADI constructed the other five ships in the class, which were all named after Australian rivers. The Australian ships, which are referred to as
612-602: The Gaeta s, Lat Ya -class ships have a slightly greater displacement of 680 tons, with a corresponding increase in draught to 2.9 metres (9.5 ft). They use Atlas Elektronik radar and sonar, Pluto ROVs, and are fitted with a 30-millimetre (1.2 in) MSI cannon. Each ship carries 8 officers, and 42 other crew. In 2004, the Finnish Navy began to look at replacements for the Kuha-class minesweepers , which had been in service since 1974. On 23 November 2006,

In 1994, a contract was awarded to Australian Defence Industries (ADI) to construct six minehunters based on

Most significant of these is that Mahamiru s are equipped with two diesel engines with dedicated propeller shafts instead of a single engine and propeller, giving them a maximum speed of 16 knots (30 km/h; 18 mph) and a minehunting speed of 7 knots (13 km/h; 8.1 mph). The Malaysian ships are also equipped with Thomson Sintra TSM 2022 sonar, Thomson-CSF radar, and two PAP-104 remote-operated submersibles, and are 1 metre (3.3 ft) longer than

Six more ships of an improved design (known as the Gaeta subclass) were ordered on 30 April 1988, with two more Gaeta s ordered in 1991. The four Lerici -class ships were launched from September 1982 through to April 1985, and were all commissioned into the Italian Navy during 1985.

The Nigerian ships are armed with two 30 mm cannons, and have a crew complement of 50, including 5 officers. Because of a lack of funding and maintenance, Ohue and Marabai were among several ships of the Nigerian Navy that were non-operational by 1996. However, as at 2013, both of these vessels are currently undergoing refurbishment prior to rejoining
