Sonobuoys are tactical sonar systems that are deployed to transmit submarine activity in anti-submarine warfare scenarios.
The current subcontracts represent a Government Fiscal Year 2018 ERAPSCO indefinite-delivery indefinite-quantity contract release for the supply of sonobuoys under the JV’s five-year deal.
Ultra Electronics chief executive officer Simon Pryce said: “I am pleased that we have secured this significant contract to provide continuing critical sensor capabilities to the US Navy.
“This contract underscores the increased focus on anti-submarine warfare and our ability through ERAPSCO to provide a range of key technologies and capabilities to support the US Navy’s continued commitment to this important mission.’
The deal will see ERAPSCO deliver production subcontracts valued at $30.3m and $34.3m to Ultra Electronics USSI and Sparton De Leon Springs respectively.
Sparton interim president and chief executive officer Joe Hartnett said: “Undersea warfare is a vital part of the defence of our nation and our allies throughout the world.
“We are honoured that the navy continues to rely on us to manufacture a product so fundamental to that task.”
Production of the sonobuoys is expected to be completed by April 2020 and will be carried out at the Ultra Electronics USSI facility in Columbia City, Indiana, and Sparton’s manufacturing site in De Leon Springs, Florida.
The ERAPSCO JV secured $28.4m worth of subcontracts for the supply of sonobuoys for the US Navy in March.
