Moorestown NJ (SPX) Dec 05, 2007 – Lockheed Martin successfully demonstrated a new Extreme Short Range (ESR) mode for its family of SPY-1 naval radars – a radar family most noted for its unmatched performance detecting and tracking ballistic and supersonic cruise missiles. This new ESR mode provides an additional layer of ship defense that supports close-in operations, such as helicopter approach control, and enhances small surface target detection and performance in the littorals.
