The AN/SPQ-11 Cobra Judy was a PESA radar found on the Template:USNS missile range instrumentation ship.
It was used for space tracking, ballistic missiles tracking and other instrumentation. Cobra Judy was the Airforce code name for the afloat phased-array radar that was designed with a primary mission of monitoring Soviet missile tests and which operated in conjunction with land based phased-array radar Cobra Dane and Cobra Ball aircraft.[1] Cobra Judy was replaced by the Cobra Judy Replacement (CJR) in April 2014.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/SPQ-11" designation represents the 11th design of an Army-Navy electronic device for surface ship special radar system.[2][3] The JETDS system also now is used to name all Department of Defense electronic systems.
