SES Space & Defense awards Comtech order for next-generation modems to operate on O3b mPOWER constellation

SES Space & Defense has awarded Comtech an order for software-defined SLM-5650B and other next-generation modems. Initial quantities under this new contract are expected to be delivered over the next year.


“In today’s threat environment, secure, resilient, and ubiquitous connectivity is critical to maintaining an information advantage across all domains,” said John Ratigan, Interim CEO of Comtech. “This contract award further demonstrates the trust of SES Space & Defense in Comtech’s ability to deliver next-generation digital solutions. O3b mPOWER is among the world’s most innovative satellite constellations, and we are thrilled to partner with SES Space & Defense as they pave the way for modernized military satellite communications (“SATCOM”) operations.”


“We choose customer mission success first. Comtech’s SLM modem series includes features that are unique and critical to our customers’ missions,” said David Fields, President and CEO of SES Space & Defense. “It is important that Comtech is part of the O3b mPOWER service infrastructure. Their experience developing and manufacturing defense-oriented modems that are ‘allied by design’ with footprints in many domestic and international programs of records make it an easy decision.”


Developed and manufactured at its headquarters in Chandler, AZ, Comtech’s SLM-5650B is the Company’s current Wideband Global SATCOM-certified modem designed to deliver critical communications services for commercial backhaul and government and military applications. The software-defined SLM-5650B currently supports multiple critical DoD and NATO waveforms including DVB-S2X, the preferred waveform for SES’ O3b mPOWER constellation, with the ability to easily add more waveforms and functions to meet emerging mission needs.


Comtech’s portfolio of US sovereign defense technologies and services, including the Company’s SLM-5650B and next-generation modems, align with the Space Force Commercial Space Strategy and deliver capabilities that will enhance Combined Joint All Domain Command and Control operations. Comtech’s expansive portfolio of defense and security technologies is designed to continuously evolve over time to enable digitalized SATCOM infrastructures and integrate services across blended military and commercial networks to significantly enhance mission effectiveness in future all-domain operations.
