Mercury Systems has received follow-on orders worth $2m to deliver advanced digital radio frequency memory (DRFM) jammers to support the US Navy requirements.
The latest order is part of the firm-fixed-price, indefinite delivery/indefinite quantity (IDIQ) time and material contract award, worth up to $44.4m, originally received by KOR Electronics (now Mercury Defense Systems) in March 2010.
The IDIQ contract was extended by the US Navy to include an additional 63 units for a total contract value of $56.7m.
Mercury Defense Systems president Brian Perry said: "This award is a further acknowledgement of the company's continuing effort to support the warfighter.
"For more than 20 years, our DRFM products have been used for self-protection, vulnerability assessment, training and radar environment simulation. Our successful performance under firm-fixed-price contracting is the cornerstone of our business."
The jammers are expected to be shipped by the end of the third quarter of 2016.
Mercury's Airborne 1225 ruggedised air-cooled, airborne 3-bit miniaturised DFRM comes with storage for up to 48 user-defined deception programmes. Over 130 units have been produced so far for multiple users.
The system has been developed for airborne, pod and UAV applications with up to 1,200MHz instantaneous bandwidth.
Mercury's solutions are used in a variety of critical defence and intelligence applications in more than 300 programmes, including Aegis, Patriot, SEWIP, F-35 and Gorgon Stare.
