TPY-4, previously known as TPY-X

TPY-4 is a multi-mission, ground-based radar for air defense surveillance that can operate in contested electromagnetic environments and provides the warfighter an ability to detect and track current and emerging threats. Gallium Nitride (GaN) technology in the system also provides greater efficiency and improved reliability as compared to legacy systems.

Radar System that Maximizes Flexibility and Mission Capability

Proven, Low-Risk Solution Performance

Proven, Low-Risk Solution Performance

A solution that effectively balances performance, prime power, weight, heat dissipation and cost when constrained by tactical mobility and extreme operating environments. Our rotating Active Electronically Scanned Array (AESA) incorporates Gallium Nitride (GaN) transmitter technology, distributed digital architecture concepts, and advanced signal processing techniques proven and tested.
Operator / Maintainer-Focused
