Missile Warning and Defense
Serious efforts to defend against ballistic missile threats began over three decades ago. Since then, the challenges have expanded in magnitude and source, with adversaries developing missile capabilities in increasing number and capability.
L3Harris has answered the call to protect against these advanced threats, with technology based in space and on Earth that keeps the United States and allies safe.
In an increasingly contested environment, our national security depends on multi-layered solutions. From bus to payload, build to launch, and operations to algorithms, L3Harris delivers these unique capabilities rapidly and affordably.
Space-Based Technologies
Threats to missile warning and defense assets grow by the day.
In addition to rogue satellites and space debris, directed physical attacks and cyberattacks highlight the emerging risks the U.S. military must be prepared to combat.
L3Harris addresses that danger with end-to-end missile defense solutions that are responsive, resilient, affordable and quickly deployable at scale.
Our advanced sensor technology finds, tracks and targets hypersonic vehicles that elude other capabilities.
It adds a vital tool to the U.S. military’s multi-layered approach to eliminating danger wherever it appears.
Features and Benefits
- End-to-end capabilities that support responsive space missions, including, bus, payload, engineering design, mission planning, integration, testing, launch, operations and deliverable intelligence
- Secure and scalable ground infrastructure provides command and control of responsive space constellations as well as data processing
- Mission-defining sensor technology provides critical missile detection with precision infrared imaging technology that can be produced at volume
- Production capabilities built upon years of space mission experience but with the commercial speed of a nontraditional vendor
- Experience launching reconfigurable, multi-mission, software-defined payloads at scale
- Record of cost-effectively meeting right-sized performance requirements and balance lifecycle costs across an entire smallsat constellation architecture
- Years of delivering essential payloads in multiple orbits
Multi-Layered, Multi-Domain Solutions
In an increasingly contested space environment, a multi-layered approach can significantly reduce risk along the threat-elimination chain.
