High Frequency Modernization

Abstract

This modification replaces the legacy HF radio with a modernized HF radio on KC-135 aircraft to operate in a SATCOM-denied environment while maintaining global, secure voice/data between Mobility Air Forces' aircraft and command and control (C2) agencies to exchange classified information. This complies with DoD directive to modernize HF capability. If requirements are not met, then KC-135 aircraft loses BLOS communication capability with MAF aircraft and C2 agencies if satellite connectivity is lost. Additionally, KC-135 aircraft loses the capability to use HF for Air Traffic Control communication during transoceanic flights. This form fit radio replaces the current ARC-190 radio with the new ARC-260 radio.
