TERRESTRIAL LAYER SYSTEMS (TLS)

The Terrestrial Layer Systems (TLS) program is a key part of the Army's modernization strategy, aimed at enhancing multi-domain operations and deep sensing capabilities. The TLS Brigade Combat Team (BCT) focuses on providing Army maneuver forces with integrated full-spectrum Signals Intelligence (SIGINT), Electronic Warfare (EW), and Cyber-enabling options. This integration is designed to offer non-kinetic offensive capabilities to Brigade Combat Team commanders, thereby improving decision-making processes, targeting accuracy, and offering electronic attack and cyber warfare options to manipulate adversary forces.

The TLS BCT utilizes advanced modular systems that can be adapted for various operational configurations. This adaptability ensures effectiveness against evolving threats from near-peer adversaries. The program's design allows for efficient upgrades and sustainability, addressing capability gaps in multi-domain operations. A significant portion of the investment is allocated to research, development, testing, and evaluation.

Beyond the BCT focus, the Terrestrial Layer System Echelon Above Brigade (TLS EAB) extends these capabilities to higher command levels such as Army Divisions, Corps, and Multi-Domain Task Forces. The TLS EAB provides extended-range sensing and electromagnetic attack capabilities by combining SIGINT, EW, and Cyber effects. This system enhances situational awareness and understanding for commanders during large-scale combat operations by delivering synchronized lethal and non-lethal effects.

For FY 2025, resources support the procurement and initial deployment of TLS BCT systems, including both Manpack and Stryker variants. It also covers system engineering efforts necessary for acquisition documentation development. For the TLS EAB, resources are allocated for critical long-lead items required for initial production systems, supporting preparations for future production decisions. These efforts align with strategic objectives outlined in defense authorization acts to ensure readiness across active and reserve components for various defense missions.
