MVFreedom Star is a formerly NASA-owned and United Space Alliance-operated vessel which primarily served as an SRBrecovery ship following the launch of Space Shuttle missions. It also performed tugboat duties and acted as a research platform.
Freedom Star underwent special strengthening enhancements to withstand the greater burden of towing the external fuel tanks. The stern was strengthened at critical points, new bulwark fairings were added, and an H-bitt was installed through which cabling is threaded to keep it centered during towing operations. Also installed was a hydraulictowing winch, referred to as a double-drum waterfall winch, holding 2,000 feet (610 m) or more of wire rope on each drum. One drum supports booster retrievals while the other is devoted to external tank towing.
Each ship is propelled by two main engines providing a total of 2,900 horsepower. The main engines turn two seven-foot (2.1-meter) propellers with controllable pitch, which provides greater response time and maneuverability. The ships also are equipped with two thrusters. The stern thruster is a water jet system that allows the ship to move in any direction without the use of propellers. This system was installed to protect the endangered manatee population that inhabits regions of the Banana River where the ships are based. The system also allows divers to work near the ship during operations at a greatly reduced risk.[9]
On November 6, 2015, USNS Freedom Star arrived at the Piney Point, Maryland-based maritime training school to become the Paul Hall Center's training vessel, on loan from MARAD's James River Reserve Fleet in Jamestown, Virginia. At the school, the Freedom Star replaces the Osprey, a yard patrol type vessel that served as the school's training platform from 1996 to 2009.[5][11][12]
