The AN/SPY-6 is an active electronically scanned array (AESA) 3D radar system developed and built by RTX Corporation, and in service with the United States Navy (USN). It provides integrated air and missile defense for Flight III s. Variants are under development for retrofitting Flight IIA Arleigh Burkes and for installation aboard s, s, s (LHA-8 and future), and s. The first delivery of the AN/SPY-6 to the USN took place on 20 July 2020.

shipborne multi-function radar

The AN/SPY-3 is an active electronically scanned array radar manufactured by Raytheon and designed for both blue-water and littoral operations.

The AN/SPG-62 is a continuous wave fire-control radar developed by the United States, and it is currently deployed on warships equipped with the Aegis Combat System. It provides terminal target illumination for semi-active surface-to-air missiles. The antenna is mechanically steered, uses a parabolic reflector, and operates at 8 to 12 GHz (X Band). The system is a component of the Mk 99 fire-control system (FCS).

The SAMPSON is a multi-function dual-face active electronically scanned array radar produced by BAE Systems Maritime. It is the fire control radar component of the Sea Viper naval air defence system. The Sea Viper system is also known as PAAMS(S) to denote the use of the SAMPSON radar and to distinguish it from the PAAMS system on the Franco-Italian Horizon-class frigate.

Seetakt was a shipborne radar developed in the 1930s and used by the German Navy (Kriegsmarine) during World War II. It is the first naval radar to enter service, and among the earliest radars of any sort. It provided range measurements with an accuracy on the order of , more than enough for gunnery. Its angle accuracy was not very good, but the development of lobe switching specifically for this radar provided about 1 degree accuracy, not enough to directly lay the guns, but still useful for initial plotting and aiding the optical spotters find their target.

It is designed to be the principal radar system aboard naval vessels of medium and large sizes. The radar offers full volumetric search coverage, low altitude and surface search, the tracking of multiple targets, and the capability to uplink in

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.

The S1850M is manufactured by Thales and BAE Systems Integrated System Technologies (formerly AMS UK). It is a modified version of the Thales Nederland SMART-L radar. The S1850M is advertised as being capable of fully automatic detection, track initiation, and tracking of up to 1,000 targets at a range of . It is also claimed to be highly capable of detecting stealth targets, and able to detect and track outer atmosphere objects at short range, enabling it to form part of a T

AN/SPS-39 is a three-dimensional radar was manufactured by Hughes Aircraft Company. It was used by the US Navy as a parabolic-cylinder reflector antenna after World War II, and was equipped aboard naval ships during the Cold War. It was mass-produced based on AN/SPS-26, and was also the first 3D radar deployed by the US Navy in the fleet. It later evolved into an improved AN/SPS-52.

thumb|AN/SPG-60 Radar The AN/SPG-60 (pronounced as "SPIG sixty") 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.

The AN/SPG-53 was a United States Navy Gun Fire-control radar (International Telecommunication Union classification: radiolocation land station in the radiolocation service), used in conjunction with the Mark 68 gun fire-control system.

Chinese naval search radar

Pantsir-M () is a Russian jamming-resistant naval close-in weapon system (CIWS) which entered service in 2018. Pantsir-M will replace Kashtan-M systems in Russian Navy.

OPS-12 is a shipborne long range air search 3D radar adopting passive electronically scanned array (PESA) technology. It was one of the first PESA radars employed on an operational warship, introduced in 1980 by the Japan Maritime Self-Defense Force. The OPS-12 is reported to have a range of more than 200km, and a target passive track capability of up to 100 contacts simultaneously.

Swedish fire control radar

FCS-1 was a Japanese ship gun fire-control system (GFCS).

The Hughes SCANFAR was the first phased array radar system to be deployed by the US Navy, installed on the and . It consisted of two search radars, the AN/SPS-32 and the AN/SPS-33. In 1982, the system was removed from Long Beach, and was replaced by the AN/SPS-48 during a comprehensive overhaul. Aboard the Long Beach, the system used AN/SPG-55 radars for missile guidance.

Type 81 Fire Control System (FCS-2) is a Japanese shipboard gun and missile fire-control system. This series of systems has been installed on destroyers of the Japan Maritime Self-Defense Force built between FY1977 and FY2001 to control medium-caliber guns and Sea Sparrow missiles, including ESSM.

Thales Naval Nederland (formerly Signaal) MW08 is a G-band passive electronically scanned array target indication 3D radar, part of the 3D multibeam 'SMART' (Signal Multibeam Acquisition Radar for Tracking) family which includes E/F band (former S band) SMART-S/SMART-S Mk2 and D band (former L-band) SMART-L.
