Yard Patrol Craft - YP
Yard Patrol craft are used for training and for research purposes.
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, Maryland. These craft can cruise for 1,800 nautical miles at 12 knots for five days without refueling.
The new Training Patrol Craft (YP) are designated the YP 703 class. The general craft characteristics of the YP 703 class emphasize habitability, training areas, hull structure, integrated bridge, maneuverability, propulsion plant configuration, and, for training purposes only, simulated underway replenishment. The main and auxiliary systems and electronics are state-of-the-art, commercial-off-the-shelf equipment. Design, construction, and selection of systems, sub-systems, and equipment along with associated software are consistent with reduced total ownership cost and facilitate system maintenance and periodic upgrades.
The primary mission of the Training Patrol Craft (YP) is to provide the midshipmen professional training course with practical training afloat on a robust platform to conduct professional development in a safe shipboard environment equipped with systems essential to modern seamanship and navigation. Such training is designed to develop within midshipmen the abilities of an officer-of the deck, a proficiency in navigation, and a working knowledge of afloat operations.
YP 701 is used at the Naval Undersea Warfare Center Division, Keyport, Washington, 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.
