Under the five-year, indefinite delivery / indefinite quantity (IDIQ) contract, ERAPSCO will provide production subcontracts worth $46.8m and $54.3m to Ultra Electronics USSI and Sparton De Leon Springs respectively.
Production work on the sonobuoys will be performed at Ultra Electronics USSI’s facility in Columbia City, Indiana, and Sparton’s plant in De Leon Springs, Florida, US, and is expected to be completed next year.
Ultra Electronics 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.
It can be deployed for detection, classification, and localisation of adversary submarines during peacetime and combat operations.
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.
Recently, the Erapsco joint venture secured subcontracts worth $53.7m to manufacture sonobuoys in support of multiple underwater missions.
