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 Lericis" or as the Gaeta class. The class design has also been used as the basis for ships of the Royal Malaysian Navy (as the Mahamiru class), the Nigerian Navy, the United States Navy (as the ), the Royal Australian Navy (as the ), and the Royal Thai Navy (as the Lat Ya class). Three updated vessels were constructed for the Finnish Navy (the ). The Republic of Korea Navy operates an unlicensed derivative, known as the Ganggyeong class. Design and service history Twelve ships were constructed by Intermarine SpA between 1985 and 1996. The first four, referred to as the Lerici subclass) were ordered on 7 January 1978. Six more ships of an improved design (known as the Gaeta subclass) were ordered on 30 April 1988, with two more Gaetas ordered in 1991. Lerici class The four Lerici-class ships were launched from September 1982 through to April 1985, and were all commissioned into the Italian Navy during 1985. Lerici-class ships have a displacement of 620 tons full load, long, wide, and a draught of . The ships have a maximum speed of , provided by a single diesel engine (GMT BL.230-8M for ) connected to an electric engine () with a variable-pitch propeller. This speed is reduced to for mine-warfare operations; three active rudders (small propellers mounted in a unit which can rotate through 360 degrees, powered by three diesel-engines generators Isotta Fraschini ID-36-SS6V) are used to keep the minehunters on station. The ships have a range of 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. CMS (Combat Management System) is Datamat MM/SSN-714(V)3. Two navigation radars: one GEM Elettronica SPN-754 (I band) and one GEM Elettronica SPN-753(V)1 ARPA (I band), completed by integrated navigation system Motorola MRS
