[2] This speed is reduced to 6 knots (11 km/h; 6.9 mph) 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.

[2] 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.

[1][4] However, an inflexible export policy and demands by Intermarine that all ships be built in Italy are believed to have prevented wider sales.

[5] The Royal Malaysian Navy operates four ships based on the Lerici class design: KDs Mahamiru (11), Jerai (12), Ledang (13), and Kinabalu (14).

[6] The four ships were ordered from Intermarine on 20 February 1981, commissioned into the Royal Malaysian Navy on 11 December 1985, and arrived in Malaysia on 26 March 1986.

[6] 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 the Italian vessels they were based on.

[6] In 2008, Mahamiru and Ledang were modernised by Thales as part of the Royal Malaysian Navy's Service Life Extension Program.

[7] The TSM 2022 sonars were upgraded to the Mark III version, and the ships were reconditioned to meet a minimum of ten more years active service.

[8] The Nigerian Lericis are based on the Mahamiru class, but use the Pluto submersible, a Racal Decca 1226 radar, and are slightly slower with a maximum speed of 15.5 knots (28.7 km/h; 17.8 mph).

[10] The operating capabilities of the Bay class were found to be severely lacking, with four of the six ships cancelled before construction started.

[10] In 1994, a contract was awarded to Australian Defence Industries (ADI) to construct six minehunters based on the Gaeta subclass.

[10] The Australian ships, which are referred to as the Huon class, have a slightly greater displacement and draft than the Gaetas.

[10] The ships use a GEC-Marconi Type 2093 sonar, two SUTEC Double Eagle remote mine disposal vehicles, and are armed with a 30 mm DC30B gun.

[10] Eight minehunters based on the Gaeta class were ordered by the Royal Thai Navy on 19 September 1996, after Intermarine won the tendering process initiated in April that year.

[11][12] In comparison to the Gaetas, 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).
