The MPL radios are engineered to process warfighting data, supporting Integrated Broadcast System-low Earth orbit (IBS-L) and tactical satellite communications. Meanwhile, the CXK-1000 radios facilitate Ka-band communication, enabling the seamless transmission of data between satellites. These technologies play a pivotal role in enhancing national security through advanced space-based capabilities.
T2 Transport Layer Beta is part of the SDA’s Proliferated Warfighter Space Architecture. This initiative seeks to establish a robust network of military satellites in low-Earth orbit, ensuring resilience and layered defence capabilities. L3Harris has also made progress across other SDA programs, including missile-tracking and warning systems.
In early 2024, L3Harris launched four missile-tracking satellites under the SDA’s Tranche 0 (T0) Tracking Layer program. These satellites aim to demonstrate global indications, warning, tracking, and targeting of advanced threats like hypersonic missiles. For Tranche 1 (T1), the company is building 16 satellites featuring infrared sensors and algorithms for real-time threat detection and data fusion, set to launch in 2025.
Further cementing its partnership with the SDA, L3Harris was awarded a USD 919 million contract in early 2024 to develop 18 infrared space vehicles for the Tranche 2 (T2) Tracking Layer. This constellation will deliver near-global missile warning and tracking coverage, strengthening defence capabilities.
Ed Zoiss, President of Space and Airborne Systems at L3Harris, highlighted the company’s commitment to innovation. “L3Harris is proud to be a leading partner to the Space Development Agency in the rapid development of missile warning and missile defence technologies in support of national security,” he said. “We’re able to leverage our extensive experience and innovative approach to continuously refine and enhance capabilities across each tranche, accelerating the launch of mission systems into orbit on faster timelines.”
