Raytheon to provide high-speed SATCOM submarine antennas for EHF and SHF communications at periscope depth

The Sub HDR antennas provide submarines with high-capacity communications in the extremely high frequency (EHF) and super high frequency (SHF) bands.

SAN DIEGO – Satellite communications (SATCOM) experts at Raytheon Technologies Corp. will provide the U.S., United Kingdom, and Australian navies with high-speed SATCOM antennas for submarines under terms of a $90.3 million contract announced Thursday.

Officials of the Naval Information Warfare Systems Command (NAVWAR) in San Diego are asking the Raytheon Intelligence & Space segment in Marlborough, Mass., to provide 23 Submarine High Data Rate (Sub HDR) antenna systems.

The Sub HDR antennas provide submarines with high-capacity communications in the extremely high frequency (EHF) and super high frequency (SHF) SATCOM bands and enable reception of Global Broadcast Service messages.

The Sub HDR connects submariners to the above-sea world by giving them high-rate data multi-band SATCOM capability. Submariners deploy Sub HDR by raising a mast-mounted antenna above the ocean's surface, while the submarine remains submerged at periscope depth where the boat is difficult to detect.

The system can send and receive mission-critical information such as secure wideband multi-media, voice and data traffic, imagery, and video teleconferencing. Sub HDR enables underwater forces to participate in coordinated fleet battle group operations.

On this contract Raytheon will do the work in Largo, Fla.; Marlborough, South Deerfield, and Stow, Mass.; Fairfield, N.J.; Portsmouth, N.H.; Woodland Hills and Torrance, Calif., and should be finished by January 2024.
