Vigilant™

CONQUER THE WAVES

Introducing L3Harris’ Vigilant family of digital radar ESM solutions

For the past 60 years, L3Harris has developed technologies that detect, protect and help project naval power anywhere on Earth. We lead the field in providing maritime ESM solutions for allied naval surface and subsurface vessels – with systems installed in over 20 maritime fleets worldwide.

Now, we’re leveraging our unmatched, decades-long ESM expertise to introduce the Vigilant™ family of digital, software-defined radar ESM solutions.

The Vigilant family provides allied naval forces with advanced situational awareness and threat detection capabilities that are adaptable and robust against spectrum congestion – enabling mission success.

Our solutions leverage new digital sensor technology, a modular open architecture and software-defined electronic warfare (EW) capabilities to increase functionality, upgradability and ease of operation while decreasing long-term sustainment costs.
