U.S. Army Develops WiSPR Radar for Enhanced Vehicle Defense

9/10/2025

Summary

Story summary

The U.S. Army is creating the Wideband Selective Propagation Radar (WiSPR) to improve armored vehicle protection against anti-tank threats.
WiSPR employs an active electronically scanned antenna array for covert communication and threat detection.
Currently in production, it addresses vulnerabilities exposed by recent global conflicts.
The Protected Anti-jam Tactical SATCOM (PATS) Key Management System (KMS) Prototype secures military satellite communications during jamming.
PATS KMS uses innovative protocols for real-time key distribution, essential for the Department of Defense's next-generation SATCOM architecture.

History

Historical Context

The U.S. military's experience in Iraq in 2003 revealed vulnerabilities in armored vehicle protection against anti-tank threats, prompting advancements like the Joint Tactical Radio System for secure communications. This evolution continued with the development of the WiSPR radar system, which utilizes active electronically scanned antennas, highlighting the military's ongoing need for innovative solutions to address emerging global threats.
