Missile Warning and Defense

Space-Based Technologies

SDA OV1

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

A Standard Missile-3 (SM-3) Block 1B interceptor missile is launched from the guided-missile cruiser USS Lake Erie (CG 70) during a Missile Defense Agency and U.S. Navy test in the mid-Pacific. The SM-3 Block 1B successfully intercepted a target missile that had been launched from the Pacific Missile Range Facility at Barking Sands in Kauai, Hawaii. Lake Erie detected and tracked the target with its onboard AN/SPY-1 radar. The event was the third consecutive successful intercept test of the SM-3 Block IB mi
