Rocket Lab Corporation, through its subsidiary Rocket Lab USA, Inc., signed an agreement on December 17, 2025, with the U.S. Space Development Agency (SDA) valued at $816 million ($806M base plus $10M options) to design, manufacture, operate, and sustain 18 satellites for the Tracking Layer Tranche 3 under the Proliferated Warfighter Space Architecture. The Item 7.01 discloses a press release issued December 19, 2025, detailing the award. Work commences immediately, with satellites for launch expected by 2029. The agreement permits termination for convenience by either party, subject to conditions, highlighting standard government contract risks like customer rescheduling or cancellation.

This landmark SDA contract significantly expands Rocket Lab's revenue backlog into defense space systems, diversifying beyond launches and validating its end-to-end satellite capabilities. Near-term operational ramp-up will drive revenue recognition starting FY2026, with multi-year cash flows through 2029, though options and termination risks temper full value assurance. Strategically positions RKLB in proliferated architectures; investors should monitor execution milestones for stock upside.
