The AN/SPG-59 was an advanced phased array radar developed by the U.S. Navy starting in 1958. It was intended to offer search, track and guidance from a single radar system and antenna. Paired with the new Typhon missile, the system was to provide wide-area air defense out to about from suitable anti-aircraft cruisers. Both the radar and missile proved to be well beyond the state of the art of the era, and the project was eventually canceled in December 1963.
