Large Scale Vehicle - LSV 2

Description
The world's largest unmanned autonomous submarine.

Features
LSV 2 Cutthroat offers a cost effective and scalable research and development platform which enables advanced research and development in the areas of submarine hydroacoustics, hydrodynamics, and radiated noise reduction.

Background
LSV 2 Cutthroat provides submarine design engineers a readily available submarine platform to install and test advanced submarine technologies.

Cutthroat, a 205-ton, battery-operated, large-scale submarine test vehicle, is a 1/3 scale model of the Virginia-class attack submarine and is used to affordably explore and test emerging technologies while conducting physics-based experiments. Cutthroat was designed with specific emphasis towards supporting submarine stealth, hydrodynamics, hydroacoustics and submarine propulsion designs to permit technology insertion into current and future U.S. Navy submarines.

LSV 2 provides the capability to develop and evaluate the effectiveness of new technologies that have resulted in major improvements in performance for the Virginia class, and is now being modified to support the development of the nationís next strategic ballistic submarine, the Ohio Replacement SSBN.

Cutthroat has been operating at the Acoustic Research Detachment in Bayview, Idaho, located along Lake Pend Oreille, since its delivery in 2001. The facility is operated by the Naval Surface Warfare Center Carderock Division.
