UTC Aerospace Systems has secured a $39m contract from the US Navy's Naval Surface Warfare Center to deliver sonar domes for surface combat ships.
Under this contract, UTC will be responsible for shipping, installation and transportation fixtures, engineering and field services, inspection and repairs.
The contract will cover delivery of two types of sonar domes, including a sonar composite dome (SCD) and a sonar dome rubber window (SDRW).
This five-year indefinite-delivery, indefinite-quantity contract will cover deliveries through 2020 to the US Navy and foreign military sales.
Work under this contract will be carried out by the Engineered Polymer Products (EPP) team, which is part of UTC's aerostructures business unit.
Aerostructures president Marc Duvall said: "Our proven ability to provide advanced acoustic products that maximise sonar system performance gives our sailors a significant at-sea advantage.
"Our dedicated team of engineers and manufacturing experts at EPP is committed to delivering superior acoustic technologies in support of the US Navy's most advanced surface combatants."
The sonar dome is an acoustically transparent housing that surrounds the sonar transducer array used for detection, navigation and ranging. It helps acoustic energy to pass through with minimal sound transmission interference.
The SCD uses a patented composite system developed to deliver optimal structural and acoustic performance to the ship's sonar system, allowing enhanced discovery and classification of underwater targets.
The SDRW is a specialised rubber wire-reinforced structure that houses a ship's sonar system. The rubber's energy absorption and reflection properties will improve vessels' detection capability.
The SCD is mounted on the keel of FFG-7 frigates, while the SDRW is bow-mounted on DDG-51-class destroyers, as well as on CG-47-class cruisers.
