Northrop Grumman received a 56-month contract from Lockheed Martin worth up to $240 million to provide technologies for the Airborne and Maritime/Fixed Station (AMF) Joint Tactical Radio System (JTRS). An initial $186.7 million subcontract has been awarded focused on the software-defined radio development for AMF JTRS. Northrop Grumman will lead the Joint Tactical Radio (JTR) integrated product team and co-development of the JTR small airborne (JTR-SA) hardware and software. Northrop Grumman will also provide common JTR software for two JTR form factors, wideband power amplifiers, and the use of its Advanced Communications Test Center in San Diego as the integration and test site for the JTR-SA radio, waveforms and ancillaries. The development activities will take place in San Diego, and supportability studies will be conducted in Sierra Vista, Ariz. In March, Lockheed Martin was awarded the $766 million contract for the system development and demonstration (SDD) phase of the AMF JTRS program. For related news
