Terran Orbital Corporation has completed delivery of all 42 satellite bus platforms for the Space Development Agency's Tranche 1 Transport Layer program. The spacecraft, built in partnership with Lockheed Martin, will support a resilient low-Earth orbit communications network providing secure, low-latency data links for U.S. and allied forces worldwide.

"Completing delivery of all satellite buses for the SDA's Tranche 1 Transport Layer marks a major achievement for Terran Orbital and a key milestone in our work with Lockheed Martin," said Peter Krauss, Terran Orbital's President and CEO.

Krauss added that the program demonstrated the team's "relentless dedication and technical excellence," underscoring its role in building a secure and resilient space communications architecture to enhance global defense operations.

The first launch of the Tranche 1 Transport and Tracking satellites took place September 10, deploying 21 spacecraft. Nine further launches are scheduled, roughly one per month, leading to full deployment and operational status by 2026.
