- Large Scale Vehicle LSV
-
- The Large Scale Vehicle Kokanee (LSV-I)
is operated by the Acoustic Research Detachment (ARD) for the Naval Sea
Systems Command (SEA 92R). Kokanee is a one-quarter scale model of the
Seawolf (SSN-21). She is an unmanned, battery-powered, free-running model,
90 feet long, 150 tons, with batteries weighing approximately 25 tons and
requiring special, high-powered battery chargers. This large-scale structural
model was delivered to Bayview in north Idaho in November 1987 and operated
in Lake Pend Oreille for research work.

-
- Lake Pend Oreille provides a deep (1150
ft), quiet body of water where a free-field ocean-like environment is available
without the attendant problems and costs of open ocean operations. Unique
experimental hardware and floating platforms have been developed to support
a wide variety of R&D programs ranging from the measurement of flow
induced boundary layer fluctuations on sonar domes to the calibrations
of full-scale surface ship sonar transducers. The site's technical programs
typically support analytical efforts at the NSWCCD and contribute to the
development of advanced submarine and sonar designs.
-
- The Advanced Submarine Technology Development
program enhances the capability of the Large Scale Demonstrator System
to conduct hydrodynamic/hydroacoustic/flow management/maneuvering tests,
as well as development of an advanced propulsion system and sensor &
processing technologies being considered for insertion in the New Attack
Submarine.
-
- Congress authorized the Secretary of
the Navy to pursue a new Large-Scale Vehicle (LSV II) demonstrator that
is not limited by form or single hull design. In January 1997 the Naval
Sea Systems Command contracted with Newport News Shipbuilding (NNS), for
the design and construction of an Advanced Large Scale Vehicle (LSV II).
These efforts include all engineering, technical, coordination, support
and manufacturing efforts necessary to design and construct LSV II. LSV
II will replicate large scale submarines in design and capability and is
to be used as a demonstration platform for the insertion of new submarine
technologies related to deep diving, nuclear powered attack submarines.
It is envisioned that NNS will team, via a subcontract, with Electric Boat
Corporation for some of these requirements.
-
- LSV II Cutthroat, a quarter-scale version
of the New Attack Submarine (NSSN), will be the world's largest underwater
autonomous submarine vehicle. It will be used as a demonstrator vehicle
for the advanced technologies anticipated for the submarine. After delivery
in 2011, the LSV-2 will operate on Lake Pend Oreille at the Acoustic Research
Detachment in Bayview, Idaho.
