Ultra Electronics Ocean Systems has secured a modification contract to manufacture MK54 MOD 0 lightweight torpedo (LWT) array kits.

The $23m fixed-price, cost-plus-fixed-fee, and cost-only modification represents the exercise of option year three of the MK54 MOD 0 LWT programme to deliver array nose assembly kits.

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.

The Naval Sea Systems Command, Washington, DC, is serving as the contracting activity.

In June 2020, Ultra won a $45m contract modification to the previously awarded contract to produce MK54 MOD 0 LWT array kits. This contract was phase one of second option year of the array kits programme.

MK 54 is an advanced LWT designed and developed by Raytheon Integrated Defense Systems in partnership with the US Navy.

In February 2019, Ultra Electronics Maritime Systems received a sub-contract from Lockheed Martin Canada to serve as the anti-submarine warfare lead for the Canadian Surface Combatant.
