SELEX Elsag is to provide Boeing Defense, Space and Security with SRT- 270 High-Frequency radio communication systems to equip new CH-47 transport helicopters in the Mark (MK)-6 version, recently purchased by the British Ministry of Defense. The system will feature next-generation ALE (Automatic Link Establishment) capability, the international standard which allows rapid and reliable HF radio communications. SELEX Elsag already supplied the previous CH-47 MK-2A version with HF ALE1G avionic systems.

The SRT-270 is the outcome of advanced research and development activity carried out by SELEX Elsag within the High-Frequency sector. It provides voice/data radio communications for avionic applications, across the 2MHz and 30MHz frequency range. It also features high power transmission, of up to 200 Watt PEP/100 Watt AVG.

The equipment encompasses the control panel, which provides a user-friendly man-machine interface through an LCD display – compatible with night scopes – to a “loop” antenna, which, combined with the ATU (Antenna Tuning Unit), ensures effective communications on the whole HF range.

SELEX Elsag offers a deep knowledge of the avionics sector and its customers’ operational needs, thanks to 50 years of co-operation with the main aircraft companies. SELEX Elsag creates CNI (Communication, Navigation & Identification) devices and systems, complying with the highest market standards.

This contract is the result of a contest between worldwide key players. It also serves to strengthen SELEX Elsag’s international leadership within the avionic communications sector.
