The YPs are used to teach familiarization with water craft, Basic Damage Control and underway instruction of Basic to Advanced Seamanship and Navigation. Yard Patrol craft provide realistic, at-sea training in navigation and seamanship for midshipmen at the U.S. Naval Academy in Annapolis, Md., and candidates at Officer Candidate School, Pensacola, Fla. These craft can cruise for 1400 nautical miles at 12 knots for five days without refueling.
The YPs are used at the Naval Undersea Warfare Center Division, Keyport, Wash., to measure mobile underwater target and torpedo radiated noise plus ambient water noise conditions; serve as a platform for deployment of suspended, stationary, in-water acoustic targets during on-range torpedo proof and test operations; deployment of countermeasure emulator during torpedo operations; and deployment of oceanographic measurement instrumentation to determine seawater conductivity and temperature at the depth(s) of interest.
