The US Air Force’s (USAF’s) four-strong fleet of Boeing E-4B Nightwatch airborne command and control (C2) aircraft is receiving key upgrades that are designed to revolutionise the platform’s communication capabilities and effectiveness.
The service revealed on March 4 that the first of four E-4Bs had successfully completed the upgrade process, as well as an associated developmental testing programme. During the upgrade, the aircraft received Low Frequency Transmit System (LFTS) and Advanced Extremely High Frequency Presidential National Voice Conferencing Integration Program (APIP) modifications. Boeing and Collins Aerospace are working on installing the LFTS, while Raytheon Technologies is responsible for integrating the APIP modifications onto the aircraft.
