Systems based on the Rohde & Schwarz M3SR Series 4400 VHF/UHF radio family are being used for the production phase of the VHF and UHF emergency radio system for both Queen Elizabeth Class (QEC) aircraft carriers being built for the UK Navy.
A contract from the Aircraft Carrier Alliance (ACA) will see Rohde & Schwarz UK build two equipment racks for each vessel housing the V/UHF software defined radios from the company and recording equipment, incorporating the software and remote control.
The heart of the system is based on the R&SM3SR Series 4400 VHF/UHF radio family and is designed for stationary air defense, civil and military air traffic control and shipborne applications.
For civil applications, the 4400 systems were developed in line with international civil air traffic control guidelines (EN 300676) while integrating the requirements for the UHF Band I in line with EN 302617.
It provides military customers with a range of interfaces and associated proprietary frequency hopping waveforms, as well as radio communications schemes that conform to NATO standards. Military data transmission methods such as LINK 11 and LINK 22 are also supported.
