New MPMC-9323/EWS-DRS mission computer speeds development/deployment of high performance EW/RF applications with COTS-based open architecture solution

ASHBURN, Va. – October 3, 2018 – Curtiss-Wright’s Defense Solutions division today announced the MPMC-9323/EWS-DRS, the latest addition to its family of open architecture COTS-based EW RF tuner mission computers. To address today’s emerging Electronic Warfare (EW) threats, system integrators seek to deploy the maximum number of RF channels, supported with supercomputing-class processing in a chassis small and light enough to minimize the platform’s SWaP burden. Designed to ease and speed the development and deployment of EW hardware solutions to the warfighter, the MPMC-9323/EWS-DRS mission computer provides system integrators with a pre-integrated, SWaP-optimized Multi-Channel Tuner System that features a Leonardo DRS SI-9172 Vesper Tuner/Exciter. This new compact design eases the deployment of EW hardware solutions to the warfighter and speeds the development for system integrators. This RF tuner-based EW System (EWS) is ideal for countering emerging battlefield threats in COMINT and ELINT applications.

The MPMC-9323/EWS-DRS mission computer features an ideal combination of solutions. It integrates the SI-9172 3U OpenVPX™ module, a Curtiss-Wright Xilinx® Kintex®-7 XF07-523 FPGA mezzanine module, and an Intel® Xeon® D-based CHAMP-XD1 DSP engine, to provide end-to-end data flow and enables the customer to focus on their application instead of the integrated hardware architecture. Even better, this EW/RF tuner mission computer is packaged in Curtiss-Wright’s 2-slot 3U OpenVPX MPMC-9323 Mission Computing System. This rugged chassis, a compelling SWaP-optimized solution - 10.5” x 5.9” x 7.7” volume and weight of 18 lb. - is designed to meet or exceed the most demanding thermal requirements.

The MPMC-9323 chassis’s PSU3-THOR power supply also provides system designers with two additional XMC sites that can be optionally configured to support Gigabit Ethernet (GbE) ports (via an XMC-651 Ethernet Switch) or up to terabytes of data storage (via an XMC-554 SSD Flash Memory card), depending on customer application requirements. To support the SI-9172 Vesper Tuner/Exciter module’s high-performance RF bandwidth, this EWS mission computer supports the new VITA 67.3 subminiature blind-mate multi coaxial RF backplane connectors which deliver new levels of RF bandwidth and signal density.

“We are excited to extend our support for Leonardo DRS embedded RF Tuner technology with the introduction of our new Electronic Warfare System-DRS mission computer, which combines the recently announced SI-9172 Vesper Tuner/Exciter with our best-in-class DSP engine and FPGA processor modules in a compact rugged chassis,” said Lynn Bamford, Senior Vice President, and General Manager, Defense Solutions division. “This pre-integrated COTS mission computer speeds the deployment of cost-effective, proven Electronic Warfare solutions to the warfighter,”
