Kaman Aerospace, Newport News Shipbuilding Selected to Design Electric Propulsion System for Navy's DD-21 Destroyer

June 15, 2000

BLOOMFIELD, Conn.--June 15-- Kaman Aerospace Corp. (NASDAQ:KAMNA) said today that its Electromagnetic Development Center in Hudson, Mass., as part of a Newport News Shipbuilding-led team has been selected by Litton Ingalls Shipbuilding to begin preliminary design of electric propulsion motors and drive electronics in an industry competition for the U.S. Navy's next generation destroyer, the DD-21.

As part of the Newport News-led propulsion team, Kaman will be responsible for the permanent magnet propulsion motors that would drive the DD-21. Litton Ingalls Shipbuilding leads one DD-21 design team that is competing with another industry team led by Bath Iron Works.

Kaman pioneered the development of powerful, compact permanent magnet motors for industrial equipment, heavyweight vehicles, and naval machinery in the early 1990's. Compact and rugged, Kaman's motors are in use throughout the world in conditions of extreme heat, humidity, shock and vibration. Drilling equipment powered by Kaman motors is at work searching for oil and gas, 24 hours a day, 7 days a week, from the Canadian Arctic to the jungles of Indonesia.

Newport News has long recognized the importance of Kaman's compact, high performance motors for ship propulsion and has worked closely with Kaman for more than 10 years to develop key design features, such as removable magnets, to make large permanent magnet propulsion motors a practical reality. Under Newport News funding, Kaman developed and tested a 3,000 horsepower scale propulsion motor in 1995 as a proof-of-principle demonstrator of many of these key features.

The Newport News/Kaman propulsion team also includes Power Technology Incorporated, a spin-off of General Electric's former Fitchburg, Massachusetts naval machinery business. As part of the Newport News team, PTI will apply its field-proven distributed manufacturing approach to fabricate and assemble the DD-21 propulsion motor using a broad base of proven local and regional vendors.

The unique design of Kaman's DD 21 propulsion motor makes it a highly maintainable, low-cost solution that is easily adapted to a wide range of ship types. Key features include its patented use of removable magnet modules and segmented stators. The open architecture of the Newport News Integrated Power System is designed for maximum simplicity with extensive use of ruggedized commercial components to provide state-of-the-art performance at an affordable cost.
