Advancements in Tactical Data Links (TDLs) – Link-16
Executive Summary: Recent developments in Tactical Data Links, particularly Link-16, highlight significant advancements in secure military communications and the integration of new technologies. The U.S. military continues to prioritize Link-16 within its satellite communications architecture, while exploring enhancements through laser communications for higher data transfer rates. Industry partnerships and strategic initiatives are focused on maintaining interoperability and expanding capabilities to meet future operational demands.
Introduction
The Tactical Data Links (TDLs) landscape is undergoing significant transformation, with Link-16 remaining a pivotal component of military communications. Recent announcements between June 30, 2025, and July 06, 2025, underscore the ongoing efforts to enhance secure communications, integrate new technologies, and foster defense partnerships.
Advancements in Secure Military Communications
Link-16 continues to be a cornerstone of secure military communications, providing multi-domain situational awareness, command and control, and targeting information. L3Harris Technologies has been awarded a substantial contract to supply the U.S. Navy with Multifunctional Information Distribution System Joint Tactical Radio System (MIDS JTRS) terminals, which are software-defined radios used across various platforms. This contract underscores the commitment to maintaining robust and resilient communication capabilities.

Integration of New Technologies
While Link-16 remains integral, the U.S. Space Development Agency (SDA) is exploring the integration of laser communications to address the need for higher data transfer rates. Laser communications offer the potential for rapid data transmission with low latency, which is crucial for future operations requiring large data volumes. Although laser communications will not replace Link-16’s widespread adoption, they are expected to complement existing systems and enhance overall capabilities.
