Goodrich to Supply Sonar Domes for U.S. Navy Frigates, Cruisers and Destroyers

CHARLOTTE, N.C. --- Goodrich Corporation has received a contract from the Naval Surface Warfare Center-Crane, IN to provide sonar domes for U.S. Navy surface combat ships. The five-year Indefinite Delivery, Indefinite Quantity (IDIQ) contract is potentially valued at up to $33 million and covers deliveries through 2013. Work will be performed by Goodrich's Engineered Polymer Products team in Jacksonville, Fla.>> A sonar dome is an acoustically transparent housing that surrounds a ship's sonar transducer array used for detection, navigation, and ranging. The dome permits acoustic energy to pass through with minimal sound degradation. The Goodrich contract covers two types of sonar domes - a sonar composite dome (SCD) and a sonar dome rubber window (SDRW).>> The SCD, mounted on the keel of FFG-7 frigates, uses a proprietary composite system designed to provide optimal structural and acoustic performance to the ship's sonar system. SCDs, which replaced traditional rubber domes on U.S. and allied Navy frigates in 1997, provide significant savings on maintenance costs, and have the potential to last many years even under the demanding operating conditions faced by naval surface ships.>> The SDRW, bow-mounted on DD-963 and DDG-51 class destroyers as well as CG-47 class cruisers, is a specialized rubber-wire reinforced structure that houses a ship's sonar system. The rubber's unique energy absorption and reflection properties enhance the sonar system's detection capability. Goodrich has produced more than 300 SDRWs over the past four decades.
