Northrop Grumman has received a $429 million contract from the US Air Force to provide two Extremely High Frequency eXtended Data Rate (EHF XDR) payloads for the Enhanced Polar System-Recapitalization (EPS-R), the company announced on 7 June.
The EPS-R EHF system provides secure, anti-jam, low probability of detection/intercept communications for military forces. Designed to enable hosting on a separately procured satellite with other payloads, the EPS-R payloads will maintain continuity of protected military satellite communications in the North Polar Region.
The company deployed the EPS Control and Planning Segment hardware in December 2015 to operational sites at Clear Air Force Station, Alaska and Schriever Air Force Base, Colorado. CAPS is a next-generation ground system that receives telemetry and supplies configuration commands, mission planning and cryptographic planning for EPS polar-orbiting payloads.
Cyrus Dhalla, VP, communications systems, Northrop Grumman, said: ‘EPS-R provides communications services to critical national security users. We are pleased to support the air force as a system prime in the timely recapitalisation of the protected, anti-jam communications capabilities in the strategically important polar region.’
Airbus was awarded the Composante Spatiale Optique (CSO) contract at the end of 2010. This included an option for a third satellite, which was activated after Germany joined the programme in 2015.
In today’s contested operational environment, adaptability is key. The new Geospatial-Intelligence as a Service (GEO IaaS) solution from Fujitsu and MAIAR empowers militaries by enabling intelligence advantage, combining advanced technology with human expertise to deliver actionable insights.
Israel will continue to develop autonomy for its weapons and platforms as it brings together defence personnel, academia and industry.
Clavister CyberArmour, an integrated defence cybersecurity system, will be used on BAE Systems Hägglunds’ CV90 platform in deployments with a Scandinavian country, as well as in an eastern European nation.
The tactical satellite (TacSat) is an intelligence, surveillance and reconnaissance (ISR) system and will participate in exercises in 2025.
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
