Secure Mobile Anti-Jam Reliable Tactical Terminal

Secure Mobile Anti-Jam Reliable Tactical Terminal. It is a family of advanced, transportable satellite communications terminals developed for the United States Department of Defense. The system provides secure, jam-resistant, high-capacity data and voice connectivity for tactical forces in contested environments. Its primary purpose is to ensure reliable Beyond-line-of-sight communication for command and control, enabling Network-centric warfare across global operations.

Overview and Purpose

The terminal was developed to address critical vulnerabilities in military Satellite communication links to threats like Radio jamming and Electronic warfare. Its creation was driven by the need for assured Command and control for deployed units from United States Strategic Command to forward elements. The system supports the Global Information Grid by providing a mobile, protected link for transmitting sensitive data, including Intelligence, surveillance, target acquisition, and reconnaissance feeds. Fielding of these terminals enhances the connectivity of forces operating in regions like the Indo-Pacific Command and United States Central Command areas of responsibility.

Technical Capabilities

The terminal utilizes the Protected Tactical Waveform and legacy MILSTAR waveforms to provide anti-jam protection through techniques like Frequency hopping and Direct-sequence spread spectrum. It operates primarily on the Advanced Extremely High Frequency satellite constellation, part of the United States Space Force's architecture, ensuring global coverage. Capabilities include data rates supporting Video teleconferencing and rapid transfer of Common Operational Picture data. The system's Cryptography is integrated with modern National Security Agency Type 1 encryption suites, such as those used in the Secure Terminal Equipment family, to safeguard transmissions.

System Architecture

Architecturally, it consists of a satellite transceiver, Modem, Cryptographic unit, and power system integrated into a ruggedized shelter or vehicle mount. The antenna system typically features a parabolic dish with Electronically steered array technology for rapid satellite acquisition and tracking. It interfaces with tactical networks like the Joint Tactical Radio System and can be integrated with platforms such as the High Mobility Multipurpose Wheeled Vehicle and command posts. The internal electronics often incorporate technology from key defense contractors like Raytheon Technologies and BAE Systems.

Operational Deployment

These terminals are deployed with United States Army units like the 1st Cavalry Division and 82nd Airborne Division, as well as with the United States Marine Corps under programs like Marine Air-Ground Task Force. They have been used in exercises such as Operation Atlantic Resolve in Europe and real-world operations across the Middle East. The terminals enable connectivity for Tactical Operations Centers and are crucial for executing Joint Publication 3-12 on cyberspace operations. Their use was validated during missions in Afghanistan and Iraq, supporting units from Multi-National Force – Iraq to International Security Assistance Force.

Development and Variants

Initial development was led by L3Harris Technologies (formerly Harris Corporation) under contract to the United States Space and Missile Systems Center. The original SMART-T model was followed by the SMART-T Enhanced, which offered increased capacity. The latest, SMART-T Increment 2, features a modernized design with a smaller footprint and support for the Protected Tactical Enterprise Service. Development aligns with the Department of Defense's Joint Capabilities Integration and Development System process and is monitored by the Government Accountability Office. Future upgrades may involve integration with the Evolutionary Air and Space Global Laser Engagement system and the Next Generation Operational Control System for satellites.
