Ultra Electronics (USSI) and Sparton have secured subcontracts worth $53.7m from their Erapsco joint venture to manufacture sonobuoys in support of multiple underwater missions.
Under the indefinite-delivery, indefinite-quantity (IDIQ) contract, which forms part of an existing five-year deal, Erapsco will deliver production subcontracts to Ultra Electronics USSI and Sparton DeLeon Springs, worth $26.1m and $27.6m respectively.
ERAPSCO has received this contract to deliver sonobuoys that are used for detection, classification, and localisation of adversary submarines during peacetime and combat operations.
Work under this contract will be performed at Ultra Electronics USSI's facility in Columbia City, Indiana, and Sparton's De Leon Springs, Florida facility and is scheduled to be completed next year.
USSI chief executive Rakesh Sharma said: "I am pleased that we have secured this important contract that will continue to provide critical sensor capabilities to the US Navy.
"This contract is a reflection of the increased focus on anti-submarine warfare and the US Navy's commitment to providing key technology for this important mission."
The sonobuoys can be deployed to assess environmental circumstances and help install top search tactics, as well as communication with friendly vessels.
The systems are also capable of transmitting an acoustical signal source and accept underwater signals of interest, which are then delivered to monitoring units for analysis.
Last year, USSI and Sparton secured subcontracts worth $6.9m and $9.2m respectively to manufacture passive and active sonobuoys in support of multiple underwater missions.
