The first of four US Air Force (USAF) E-4B aircraft recently concluded developmental testing. It received the Low Frequency Transmit System (LFTS) and Advanced Extremely High Frequency Presidential National Voice Conferencing Integration Program (APIP) modifications.

Work on the other three aircraft will be performed in the coming years. The modification will be provided during their standard programmed depot maintenance cycle.

Presidential and Executive Airlift Directorate E-4B Materiel leader lieutenant colonel Ben Chown said: “These modifications are game-changing. The LFTS mod provides revolutionary single wire low frequency communication capability, while APIP transforms reliability and survivability of the E-4B SATCOM and national leadership command and control systems.”

A major part of the modification effort was carried out by the Command, Control, Communication, Intelligence, and Networks (C3I&N) Directorate.

This effort included escorting, securing, and transferring crypto materials integral to the evaluation, testing, and operation of the aircraft’s communications systems.

The Air Force Nuclear Weapons Center’s (AFNWC) Nuclear Command, Control, and Communications (NC3) Integration Directorate acquired the APIP systems through two different programmatic efforts.

Presidential and Executive Airlift Directorate programme executive officer brigadier general Ryan Britton said: “Superior communication capabilities are essential on the battlefield.

“The revolutionary technology that these modifications provide, delivers the US an incredible strategic advantage for command and control.”

Boeing and Collins Aerospace are installing the Low Frequency Transmit System modification, while Raytheon Technologies is responsible for the aircraft’s APIP mod.
