Northrop Grumman has awarded Leonardo with a contract for SRT-400 High Frequency (HF) radio system for the U.S. Navy’s E-2D Advanced Hawkeye Airborne Early Warning and Control (AEW&C) aircraft fleet.
Variants of the E-2 Hawkeye have been in operation since the early 1960s and the aircraft is the prime U.S. Navy ship or land based all-weather airborne early warning and command and control platform detecting and tracking targets at extended range in deep water, littoral and over-land environments.
The state-of-the-art HF Single Side Band system SRT-400 HF radio is suitable for fixed and rotary wing aircraft.
It uses a patented Leonardo technology which reduces TX power consumption by more than 40% compared to previous designs, reducing heat dissipation and greatly improving reliability.
Both transceivers can be interfaced with multiple Antenna Tuning Units (ATU) matching all kinds of existing antennas (loop, wire or notch).
The SRT-400 and its low power variant, the SRT-200, combine high flexibility and simplified operations into a reduced size and weight package achieved through innovative electrical and mechanical design.
Leonardo’s extensive research and development activities in the high frequency airborne radio field has led to the design and production of thousands of its previous generation RT-170 (170W), RT-270 (200W) and RT-470 (400W) to customers around the world.
The Italian defence conglomerate has been involved in the design and manufacture of airborne HF systems for decades.
