The contract has a two-year base period of performance and comes with three one-year options. The cumulative value of the award could reach up to nearly $36m, if all options are exercised.

On 13 September 2018, the company was awarded a $13.93m to design and develop ADC MK5 developmental devices, as well as deliver engineering and technical services and non-recurring engineering services such as software and hardware development.

“Our focus is to provide the right combination of technical depth and customer insight to deliver the right solutions within challenging operational environments.”

Leidos Defense Group president Gerry Fasano said: “We employ a different mindset on how to keep up in a dynamic and rapidly changing defence environment where world-class systems are the only option for our defence customers to accomplish their missions.

“This win opens a new market for our organisation in underwater sensors, and our focus is to provide the right combination of technical depth and customer insight to deliver the right solutions within challenging operational environments.”

The ADC MK5 is part of the navy’s next-generation countermeasure programme, which seeks to insert new technologies into submarine defence. The device will replace the existing ADC MK3 systems with the service.

The submarine-launched device will have a 3in diameter and be able to protect the vessels against modern incoming torpedoes.

Work under the contract will be carried out in the US states of Washington, Northern Virginia, Ohio, California and Florida.

Last November, Sparton teamed up with Leidos Maritime Systems to support the ADC MK5 programme.
