Their design is based on the second series of the Italian Lerici-class, built in La Spezia by Intermarine between 1990 and 1996. Eight vessels were built in the Intermarine shipyard located in Savannah, while the remaining four have been built by a second-source shipyard under a Technology Transfer and Licence Agreement.[1]
They use sonar and video systems, cable cutters and a mine detonating device that can be released and detonated by remote control. The Osprey class are the world's second largest minehunters (surpassed by the Royal Navy's 60-meter (200 ft) Hunt-classmine countermeasures vessels) to be constructed entirely of fiberglass and designed to survive the shock of underwater explosions. Their primary mission is reconnaissance, classification, and neutralization of all types of moored and bottom mines in littoral areas, harbors and coastal waterways.[2]
Twelve minehunter ships were built for the U.S. Navy by Northrop Grumman Ship Systems (formerly Litton Avondale Industries) of New Orleans and Intermarine of Savannah. The ships were commissioned between 1993 and 1999.[2] The ships of this class were named after various types of birds.[3]
The 12 ships are 187 feet 10 inches (57.3 m) long, 34 feet 7 inches (10.5 m) wide, and 70 feet 0 inches (21.3 m) tall.[2] When carrying a full load they displace 904 tonnes (890 long tons; 996 short tons).[4] They have four decks, and have a complement of five officers, four chief petty officers, and 42 enlisted men. They are armed with two .50 caliber machine guns. All of the major equipment is suspended from the main deck in glass-reinforced plastic holders, so that in the event of an undersea explosion, it will not be damaged.[2]
They use an AN/SLQ-53 deep sweep mine countermeasures system. They also use an AN/SQQ-32 Variable Depth Sonar, which is tethered to the front of the bridge, to detect and identify mines using multiple ping processing. Two AN/UYK-44 computers are also used to classify and detect mines. For surface radar purposes, an AN/SPS-64(V)9 is used. They also use the AN/SLQ-48 mine neutralization system, which is tethered to the ship by a 1.07-kilometre (0.66 mi) long cable. They have two AN/UYQ-31 operator data terminals, which are identical.[2]
All of these ships were decommissioned in 2006–07. The Hellenic Navy received two of the Osprey class from the US Navy: Heron, renamed Calypso and Pelican, renamed Euniki. Two more were transferred to the Egyptian Navy: Cardinal, renamed al Sedeeq (MHC-521) and Raven, renamed al Farouk (MHC-524). The sale of Oriole and Falcon to the Republic of China was also authorized.[5]
The U.S. General Services Administration (GS) announced in April 2014 that hull numbers MHC-51, 54, 56, 57, 58, and 62 were up for auction to be sold as an entire lot for "dismantlement purposes only." This contradicted earlier information announcing the sale of some of these vessels to foreign operators.[6] The minehunting role of this class is to be taken over by Littoral Combat Ships equipped with the Mine Counter-Measures Module.[2]

Intermarine SpA of Sarzana, Italy, was invited by the United States Navy to transfer their composite material design and production technology to the USA in support of a new Coastal Minehunter program. In response, Intermarine USA was established in 1987 following a U.S. Navy contract, awarded on a sole source basis, to build large minehunters using composite materials. Intermarine completely renovated a shipyard in Savannah, Georgia, and converted it into a modern composite manufacturing facility.
