The contract also includes the provision of associated production support material, spares, as well as engineering and hardware support services.

The LWT kits are being produced for the navies of the US, the Netherlands, Belgium, New Zealand, Spain, and Brazil under the foreign military sales (FMS) programme.

Ultra Naval Systems and Sensors president Martin Lewis said: “As we continue to provide critical components of the MK54 lightweight torpedo, we understand the ongoing need to deliver reliable and effective undersea warfare capabilities to meet the anti-submarine warfare needs of US and allied fleets.”

Work will be carried out in Braintree, Massachusetts, and Lititz, Pennsylvania, US. It is expected to be completed by April 2025.
