Naval Undersea Warfare Center, Newport, RI

Current Research Interests are as follows:

The Naval Undersea Warfare Center Division, Newport (NUWCDIVNPT) is the Navy's principal research, development, test and evaluation center for submarine warfare systems, submarine weapon systems, and submarine surface ship sonar systems. Our 2000 strong scientific and engineering staff provides expertise in science and technology; technical direction; and system design, development, test and evaluation. NUWCDIVNPT is on the forefront of developing and maintaining the best scientific and technical facilities for underwater research, supporting many important Navy programs and helping minimize risk and cost of operations. We are also the designers of virtually all underwater acoustic sensors and weapons systems operating in the Fleet today, and we introduced the use of a supercomputer onboard a submarine. Working closely with the Fleet, our scientist and engineers meet current and future operational requirements and solve technical problems. They also provide expertise in undersea warfare systems and technology to defense strategists and Navy planners.
