Mercury Systems has been contracted to support an airborne sensor processing application for fighter aircraft.
Valued at $6.5m, the purchase order will see the company provide the military with advanced programmes leveraging the latest commercial technology.
Mercury Commercial Electronics business unit president Didier Thibaud said: "Mercury's commercially-developed, modular open architecture-based secure and sensor processing subsystems provide our customers a clear upgrade path into the future.
"This allows the military to continue developing affordable advanced programmes with the assurance that as systems move toward deployment they will still be able to leverage the latest commercial technology."
Mercury's signal processing technology is expected to realise faster time to market and a lower total cost of ownership for the customer's critical airborne programme.
In April last year, the company received a $17.9m purchase order relating to the airborne sensor processing application for fighter aircraft.
The company's solutions power a range of critical defence and intelligence applications on more than 300 programmes such as Aegis, Patriot, SEWIP, F-35 and Gorgon Stare.
In 2013, Mercury Systems secured a contract from Raytheon Integrated Defense Systems (IDS) for delivery of additional OpenVPX-based radar subsystems for installation on the Patriot air and missile defence system.
Under the $3.3m deal, that represented the follow-on contract for the systems, the company supplied unspecified units of OpenVPX-based radar subsystems, along with spares to Raytheon.
