The AN/SPY-1 [a] is a United States Navy passive electronically scanned array (PESA) 3D radar system manufactured by Lockheed Martin, and is a key component of the Aegis Combat System. The system is computer controlled and uses four complementary antennas to provide 360-degree coverage.
The Navy was forced to halt the contract in response to a challenge by Lockheed. [9] Lockheed officially withdrew their protest in January 2014, [10] allowing the Navy to lift the stop work order. [11] In March 2022, Raytheon announced a $3.2B contract to outfit every new surface ship in the US Navy with the SPY-6 family of radars. [12] [13]
air target tracking of over 200 targets out to 150 km [2] surface target tracking of over 150 targets out to 32 km [2] horizon search out to 75 km [2] "limited" volume search out to 150 km [2] (in order to back up the volume search capabilities of the SMART-L) cued search (a mode in which the search is cued using data originating from another ...
The radar provides data and range safety for missile launches. This radar, along with its data system, is used for tracking the Minuteman III ICBM. The AN/FPS-16 is a highly accurate ground-based monopulse single object tracking radar (SOTR), used extensively by the NASA crewed space program
Blue force tracking (BFT) systems consist of a computer, used to display location information, a satellite terminal and satellite antenna, used to transmit location and other military data, a Global Positioning System receiver (to determine its own position), command-and-control software (to send and receive orders, and many other battlefield support functions), and mapping software, usually ...
The radar examines the track's size, speed, altitude, and heading, and decides whether or not it is a legitimate track or "clutter" created by RF interference. If the track is classified by the radar as an aircraft, in the AN/MSQ-104 Engagement Control Station, an unidentified track appears on the screen of the Patriot operators.
Due to its active radar tracking, the brevity code "Fox Three" was used when firing the AIM-54. The act of the missile achieving a radar lock with its own radar is known under brevity as "Going Pitbull". Both the missile and the aircraft were used by Iran and the United States Navy (USN). In US service both are now retired, the AIM-54 Phoenix ...
The Transit system, also known as NAVSAT or NNSS (for Navy Navigation Satellite System), was the first satellite navigation system to be used operationally. The radio navigation system was primarily used by the U.S. Navy to provide accurate location information to its Polaris ballistic missile submarines, and it was also used as a navigation system by the Navy's surface ships, as well as for ...
