“Cobra King”

“Cobra King” (formerly known as Cobra Judy Replacement, CJR) is a mobile dual-band range instrumentation radar suite installed on the USNS “Howard O. Lorenzen”. Cobra King replaces the original “Cobra Judy” system, which has reached the end of its service life.

The upper radar is the operating in S-band phased-array radar designed by Northrop Grumman for weather-independent long-range surveillance. The lower radar is an X-band system by Raytheon, predetermined for more accurate target tracking. It also has a search capability.
