Lockheed Martin has secured a $154m contract with the US Navy to upgrade the electronic warfare systems on its fleet.

The low-rate initial production contract covers Block 2 of the navy’s surface electronic warfare improvement programme (SEWIP).

Under the deal, the company will supply systems to upgrade the AN / SLQ-32 systems on the US aircraft carriers, cruisers, destroyers, and other warships.

The upgrade will provide the navy’s fleet with capabilities to determine if a vessel is being tracked by the electronic sensors of other ships.

Lockheed Martin Mission Systems and Training electronic warfare programme director Joe Ottaviano said: "We’re proud to continue supporting the US navy with capabilities delivered on schedule to rapidly introduce new technology to the sailors.

"This contract allows us to continue providing much needed technological advance."

"Our fleets are facing a rapidly changing threat environment in theatres across the globe.

"This contract allows us to continue providing much needed technological advances that will help outpace our adversaries and protect our warfighters."

The company plans to perform work under the contract at its facility in Syracuse, New York.

SEWIP Block 2 is designed to provide enhanced electronic support (ES) capability for the AN / SLQ-32. It involves an upgraded ES antenna, ES receiver and an open combat system interface.

The programme achieved Milestone C in January 2013 with the receipt of approval to commence low rate initial production.

Lockheed was selected to provide 24 systems in 2013 and 2014, as part of the low-rate initial production, and has delivered ten systems to the navy on schedule.
