“L3Harris is committed to supporting SDA’s vision of a multi-layered missile tracking architecture with the space-based capabilities needed to track threats in real time,” said Ed Zoiss, President of Space and Airborne Systems at L3Harris. “We completed the PDR milestone in just 11 months and have already received key flight subsystems for our Tranche 2 vehicles, which will provide SDA with an innovative solution against a continually evolving threat.”
In January 2024, L3Harris was awarded a contract by SDA to design and build the satellites, equipped with advanced infrared payloads. These efforts are part of the broader Proliferated Warfighter Space Architecture (PWSA), a constellation of satellites in low Earth orbit designed to provide near-global missile warning, tracking, and defence capabilities.
The company’s work on Tranche 2 builds upon its established role in supporting SDA, having previously been awarded contracts for 38 satellites across earlier tranches. L3Harris has also delivered operational capabilities on-orbit with its Tranche 0 satellites, demonstrating its ability to meet evolving missile defence requirements.
As part of its Trusted Disruptor strategy, L3Harris continues to innovate across the spectrum of hypersonic systems. The company’s portfolio includes air-breathing scramjet engines, ramjets, solid rocket motors, warheads, and other missile technologies, bolstering both offensive and defensive capabilities.
