Sierra Space, a defense-tech space company delivering solutions for the nation's most critical missions and advancing the future of security in space, announced it has been awarded a Firm Fixed Price Other Transactional Agreement (OTA) by the Space Development Agency (SDA), with a total potential value of $798 million, to design, manufacture and deliver 18 missile warning/missile tracking/missile defense satellites for the Accelerated Missile Defense Tranche 3 (AMDT3) tracking layer. The award solidifies the company's position as a prime contractor and mission integrator in the rapidly growing national security space market.

"This contract demonstrates Sierra Space's capabilities as a formidable player in American national security," said Dan Jablonsky, CEO of Sierra Space. "We're honored to partner with SDA as a prime contractor to deliver on the nation's space-based missions. By combining cutting-edge design and manufacturing systems with industrial depth and systems integration expertise, we're able to move faster, manage risk better and deliver more cost-effective solutions. AMDT3 is proof that our approach is working, and we're just getting started."

The 18 AMDT3 satellites will be based on the Horizon spacecraft, one of three satellites in the Sierra Space Eclipse Satellite Family, the same proven platform used for the company's successful Tranche 2 Tracking Layer program. 

Sierra Space has completed all 18 space vehicle structure builds of the T2 program and is preparing for qualification testing of the nine-satellite launch configuration this summer, followed by system verification testing later this year. The AMDT3 award supports Golden Dome for America's space-based capabilities.
