Osprey (MHC 51) class ships are mine hunter-killers capable of finding, classifying and destroying moored and bottom mines. Eleven of the twelve Osprey-class Coastal Minehunter are assigned to the Reserve and homeported at Ingleside, TX. The MHC 51 has a 15-day endurance and depends on a support ship or shore based facilities for resupply. This mine hunter (coastal) is designed to operate from CONUS bases against enemy bottom and moored mines. It is the first US Navy mine countermeasures ship to be constructed of Glass Reinforced Plastic (GRP). The design is based on the Italian Navy Lerici Class. Voith-Schneider rotors replace the conventional propellers of the MCM and MSO classes. The ship will have modular sweep systems which can be installed as needed.

In the early 1980s, the U.S. Navy began development of a new mine countermeasures (MCM) force, which included two new classes of ships and minesweeping helicopters. The vital importance of a state-of-the-art mine countermeasures force was strongly underscored in the Persian Gulf during the eight years of the Iran-Iraq war, and in Operations Desert Shield and Desert Storm in 1990 and 1991. Avenger class ships are also designed as mine hunter-killers. Overall Length: 188 ft
