Leonardo’s Skybound HF Radio Set to Enhance Northrop Grumman E-2D Operations
Leonardo has secured a contract from Northrop Grumman to supply its new high frequency (HF) communication system, the SRT-400, for the U.S. Navy’s fleet of E-2D Advanced Hawkeye airborne early warning and control aircraft.
For decades, Leonardo has played a pivotal role in the design and production of airborne HF systems. Leonardo’s legacy can be traced back to the 1970s, having delivered thousands of its former-generation RT-170 (170W), RT-270 (200W), and RT-470 (400W) to clients globally.
Leonardo’s comprehensive research and innovation efforts in the airborne high frequency communication domain have culminated in the creation of the cutting-edge HF Single Side Band system SRT-400, which is designed for both fixed and rotary wing aircraft.
A patented technology from Leonardo decreases TX power usage by over 40% compared to older models, minimizing heat output and significantly enhancing reliability. Both transceivers can connect with various Antenna Tuning Units (ATU), accommodating all types of existing antennas (loop, wire, or notch).
The SRT-400 and its lower power variant, the SRT-200, offer exceptional versatility and streamlined operations in a more compact and lighter form factor achieved through sophisticated electrical and mechanical engineering.
Versions of the E-2 Hawkeye have been operational since the early 1960s. It serves as a ship or land-based, all-weather airborne early warning and command and control system, capable of detecting and tracking targets over extensive distances in deep water, coastal, and terrestrial environments.
