The “Lerici Class” is world-wide renowned for being the first of a successful family of GRP (Glass-Fibre Reinforced Plastic) MCMVs built by Intermarine using its peculiar construction technique and technology. It consists of four MCMVs, “Lerici”, “Sapri”, “Milazzo” and “Vieste”, all delivered in 1985.
The “Osprey Class” consists of twelve MCMVs, delivered to the U.S. Navy between 1991 and 1998. Eight vessels of this Class have been built in the Intermarine shipyard located in USA (Savannah – Georgia), while the remaining four have been built by a second-source shipyard under a Technology Transfer and Licence Agreement by Intermarine.
The “Huon Class” consists of six MCMVs, “Huon”, “Hawkesbury”, “Norman”, “Gascoyne”, “Diamantina” and “Yarra”. The first vessel of this Class has been built at Intermarine, while its outfitting and the whole construction of the remaining five have been performed, with the initial assistance of Intermarine personnel, by the Australian company ADI (Australian Defence Industries) in Australia under a Technology Transfer and Licence Agreement.
The “Katanpää Class” consists of three MCMVs (“Katanpää”, “Purunpää” and “Vahterpää”) delivered to the Finnish Navy. The appearance of the vessels is quite different from the other Intermarine MCMV, and also the Mission System is very innovative, being based on extensive use of Autonomous Underwater Vehicles and redundancy on the MDVs (both reusable and expendable systems are available).
