WASHINGTON --- American Superconductor Corporation, a leading energy technologies company, and Northrop Grumman Corporation announced today at the Surface Navy Associations 21st National Symposium the successful completion of full-power testing of the worlds first 36.5 megawatt (49,000 horsepower) high temperature superconductor (HTS) ship propulsion motor at the U.S. Navys Integrated Power System Land-Based Test Site in Philadelphia.>> This is the first successful full-power test of an electric propulsion motor sized for a large Navy combatant and, at 36.5 megawatts, doubled the Navys power rating test record.>> This system was designed and built under a contract from the Office of Naval Research to demonstrate the efficacy of HTS motors as the primary propulsion technology for future Navy all-electric ships and submarines. Naval Sea Systems Command (NAVSEA) funded and led the successful testing of the motor.>> Incorporating coils of HTS wire that are able to carry 150 times the power of similar-sized copper wire, the motor is less than half the size of conventional motors used on the first two DDG-1000 hulls and will reduce ship weight by nearly 200 metric tons. It will help make new ships more fuel-efficient and free up space for additional warfighting capability.>> The successful load test of our HTS motor marks the beginning of a new era in ship propulsion technology, said Dan McGahn, senior vice president and general manager of AMSC Superconductors. This motor provides the U.S. Navy with a truly transformational capability relative to size, stealth, endurance and survivability, providing our Navy with a clear performance advantage for years to come. We are grateful for the steadfast support from the Office of Naval Research, Naval Sea Systems Command and the Naval Surface Warfare Center.
