AN/APY-9 Radar

The AN/APY-9 is Lockheed Martin's UHF airborne early warning radar for the E-2D Advanced Hawkeye, combining mechanical and electronic scanning to build a 360-degree air and surface picture. Official Navy and company sources describe it as the E-2D's primary sensor, designed to detect small, highly maneuverable targets in littoral and overland environments.

Exact model: AN/APY-9 UHF AESA radar for the E-2D Advanced Hawkeye. Although E-2D aircraft are operationally deployed, I found no public source tying the AN/APY-9 itself to a specific conflict engagement as a weapon system.
