AEHF Secure Communication Satellite

Full Specifications

The Advanced Extremely High Frequency satellite, known as AEHF, is the backbone of the United States most secure military communications network. It is built to keep commanders connected even during nuclear conflict, cyber attacks, or heavy electronic jamming.

Developed by Lockheed Martin with payload support from Northrop Grumman, AEHF is a U.S. strategic satellite system operated by the U.S. Space Force. The program replaces the older Milstar satellites and delivers much higher data rates, stronger protection, and wider global reach.

Mission and Role

AEHF Secure Communication Satellite supports national command authorities, nuclear forces, missile defense units, aircraft, ships, and ground forces. It provides protected voice, data, and video links across the globe. The system is designed to survive nuclear effects and operate in highly contested space environments.

Technology and Capabilities

AEHF satellites operate in geostationary orbit, allowing constant coverage of large regions. They use Extremely High Frequency and Ka band communications, combined with advanced encryption and anti jam technology. Each satellite can handle much more traffic than Milstar, while serving more users at once.

The system supports real time command and control, secure targeting data, and strategic messaging. AEHF terminals are used on bombers, submarines, surface ships, mobile ground units, and command centers.

Operational Use

Since entering service in 2010, AEHF Secure Communication Satellite has been a critical asset for U.S. and allied forces. Partner nations include the United Kingdom, Canada, and the Netherlands, which access the system under formal agreements.

AEHF Satellite Price

The estimated cost of one AEHF satellite is between USD 1.8 and 2.1 billion. This includes advanced payloads, nuclear hardening, encryption systems, and launch support. The high cost reflects its strategic role and unmatched survivability.
