Information About HFDL & Providers | Aviation NewsThe US Army is funding a series of tests on systems that deliver secure voice and data communications after they received upgraded AN/ARC-231s.

In a significant milestone for the upgrade program, testing for certification comes at the culmination of the new EDM deliveries and the contract is worth $39 million.

The VHF/UHF multi-mode, multi-band communications systems, provided by Raytheon, will be tested to provide full cryptographic certification.

HFDL is a viable, proven alternative to SATCOM on long-haul routes and can ‘stand-in’ for VHF on short-haul flights. The upgrades will allow SATCOM networking without compromising the legacy systems for air-to-air and air-to-ground communications.
