The AN/SPG-51 is an American tracking / illumination fire-control radar for RIM-24 Tartar and RIM-66 Standard missiles. It is used for target tracking and Surface-to-air missile guidance as part of the Mk. 73 gun and missile director system, which is part of the Tartar Guided Missile Fire Control System. [4]

Aircraft tracking is based on monopulse radar utilizing Pulse-Doppler radar signal processing in MK 74 MOD 14 and MK 74 MOD 15. The MK 74 MOD 15 configuration includes continuous-wave radar tracking in addition to pulse-Doppler tracking. It provides illumination for bistatic radar operation associated with missile guidance in all configurations. Older systems rely on conical scanning rather than monopulse.

<i>Arleigh Burke</i>-class destroyer Class of guided-missile destroyers

The Arleigh Burke class of guided-missile destroyers (DDGs) is a United States Navy class of destroyer centered around the Aegis Combat System and the SPY-1D multi-function passive electronically scanned array radar. The class is named for Admiral Arleigh Burke, an American destroyer officer in World War II and later Chief of Naval Operations. With an overall length of 505 to 509.5 feet, displacement ranging from 8,300 to 9,700 tons, and weaponry including over 90 missiles, the Arleigh Burke-class destroyers are larger and more heavily armed than many previous classes of guided-missile cruisers.

<i>Charles F. Adams</i>-class destroyer Class of guided-missile destroyers

The Charles F. Adams class is a ship class of 29 guided-missile destroyers (DDG) built between 1958 and 1967. Twenty-three were built for the United States Navy, three for the Royal Australian Navy, and three for the West German Bundesmarine. The design of these ships was based on that of Forrest Sherman-class destroyers, but the Charles F. Adams class were the first class designed to serve as guided-missile destroyers. 19 feet (5.8 m) of length was added to the center of the design of the Forrest Sherman class to carry the ASROC launcher. The Charles F. Adams-class were the last steam turbine-powered destroyers built for the U.S. Navy. Starting with the succeeding Spruance-class, all U.S. Navy destroyers have been powered by gas turbines. Some of the U.S. Charles F. Adams class served during the blockade of Cuba in 1962 and during the Vietnam War; those of the Royal Australian Navy served during the Vietnam War and Gulf War.

The General Dynamics RIM-24 Tartar was a medium-range naval surface-to-air missile (SAM), among the earliest SAMs to equip United States Navy ships. The Tartar was the third of the so-called "3 Ts", the three primary SAMs the Navy fielded in the 1960s and 1970s, the others being the RIM-2 Terrier and RIM-8 Talos.

<i>Cassard</i>-class frigate

The Cassard class was a class of two anti-air warfare destroyers of the French Navy introduced in the latter 1980s/early 1990s. The class was an air defence variant of the Georges Leygues class. The two classes have a different armament and propulsion system mounted on an identical hull. Their primary role was to provide air cover for a fleet, an aeronaval group, a convoy & a littoral point. Their secondary role was to manage air assets coordination & aircraft control for the force, especially through Link 16.They can also be used for research, identification or presence missions. Both ships were assigned to the Force d'Action Navale. The lead ship of the class, Cassard, was retired in 2019 followed by the retirement of Jean Bart in 2021.

<span class="mw-page-title-main">AN/SPG-55</span>

The AN/SPG-55 was an American tracking / illumination radar for Terrier and RIM-67 Standard missiles (SM-1ER/SM-2ER). It was used for target tracking and surface-to-air missile guidance as part of the Mk 76 missile fire control system. It was controlled by a UNIVAC 1218 computer.

<span class="mw-page-title-main">RIM-66 Standard</span> US medium range surface-to-air missile

The RIM-66 Standard MR (SM-1MR/SM-2MR) is a medium-range surface-to-air missile (SAM), with a secondary role as an anti-ship missile, originally developed for the United States Navy (USN). A member of the Standard Missile family of weapons, the SM-1 was developed as a replacement for the RIM-2 Terrier and RIM-24 Tartar that were deployed in the 1950s on a variety of USN ships. The RIM-67 Standard (SM-1ER/SM-2ER) is an extended range version of this missile with a solid rocket booster stage.

<span class="mw-page-title-main">RIM-67 Standard</span> Extended range surface-to-air missile with anti-ship capability

The RIM-67 Standard ER (SM-1ER/SM-2ER) is an extended range surface-to-air missile (SAM) and anti-ship missile originally developed for the United States Navy (USN). The RIM-67 was developed as a replacement for the RIM-8 Talos, a 1950s system deployed on a variety of USN ships, and eventually replaced the RIM-2 Terrier as well, since it was of a similar size and fitted existing Terrier launchers and magazines. The RIM-66 Standard MR was essentially the same missile without the booster stage, designed to replace the RIM-24 Tartar. The RIM-66/67 series thus became the US Navy's universal SAM system, hence the "Standard Missile" moniker.

The -1A was installed on ships up to CG-58, with the -1B upgrade first installed on USS Princeton in 1986. The upgraded -1B(V) was retrofitted to existing ships from CG-59 up to the last, USS Port Royal.

The AN/SPG-60 is a United States tracking radar that is part of the MK-86 Gun Fire Control System (GFCS). It is used for air tracking and on some MK-86 configurations it is also used for illumination for RIM-24 Tartar and RIM-66 Standard missiles. Though the radar is primarily an air tracking radar, the SPG-60 radar can be used for surface tracking. With the boresight mounted camera, the radar could also be used as a sight for optical tracking, optical engagement and damage assessment.
