The EL/M-2238 3D-STAR is a multi-purpose air and surface-search naval radar system developed by IAI Elta for medium-sized ships like corvettes and frigates. STAR is an acronym of Surveillance & Threat Alert Radar. [3]
It is a 3D multi-beam and multi-mode fully coherent pulse Doppler search radar which functions in the S band (2-4 GHz). It can perform both surface and aerial search simultaneously. It is designed to support anti-air and surface-gunnery systems. The antenna in the Doppler sensor has a planar array for 3D multi-beam operations and a vertical array of strip radiators. It has programmable signal processing and is stabilized within a roll and pitch of 20 degrees. It comes in three variants - a larger dual-face version, a medium version and a small single-face version. [2] [4]

The 46 Knox-class frigates were the largest, last, and most numerous of the US Navy's second-generation anti-submarine warfare (ASW) escorts. Originally laid down as ocean escorts, they were all redesignated as frigates on 30 June 1975, in the 1975 ship reclassification plan and their hull designation changed from 'DE' to 'FF'. The Knox class was the Navy's last destroyer-type design with a steam turbine powerplant.
The Halifax-class frigate, also referred to as the City class, is a class of multi-role patrol frigates that have served the Royal Canadian Navy since 1992. The class is the outcome of the Canadian Patrol Frigate Project, which dates to the mid-1970s. HMCS Halifax was the first of an eventual twelve Canadian-designed and Canadian-built vessels which combine traditional anti-submarine capabilities with systems to deal with surface and air threats as well. All ships of the class are named after the capital cities most of the Canadian provinces plus the capital of Canada, Ottawa as well as the major cities of Calgary, Montreal, and Vancouver.
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.
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
Sa'ar 5 is a class of Israeli Navy corvettes. They were Israeli designed using lessons learned from the Sa'ar 4.5-class missile boats. Three Sa'ar 5 ships were built by Huntington Ingalls Industries for the Israeli Navy, based on Israeli designs.
The Lupo class is a class of frigates built by Cantieri Navali Riuniti (CNR) for the Italian Navy. Designed as multipurpose warships with an emphasis on anti-surface warfare (ASuW), they have enjoyed some success in the export market, being acquired by the navies of Peru and Venezuela. A small run of a slightly updated version is known as the Soldati class.
The F124 Sachsen class is the German Navy's latest class of highly advanced air-defense frigates. The design of the Sachsen-class frigate is based on that of the F123 Brandenburg class but with enhanced stealth features designed to deceive an opponent's radar and acoustic sensors. The class incorporates an advanced multifunction radar APAR and a SMART-L long-range radar which is purported to be capable of detecting stealth aircraft and stealth missiles.
The F123 Brandenburg class is a class of German frigate. They were ordered by the German Navy in June 1989 and completed and commissioned between 1994 and 1996, replacing the Hamburg-class destroyers. The ships primarily carry out anti-submarine warfare (ASW), but they also contribute to local anti-aircraft defenses, the tactical command of squadrons, and surface-to-surface warfare operations. Together with the F124 Sachsen-class frigates, they are the mainstay of the German surface fleet.
Active Phased Array Radar (APAR) is a shipborne active electronically scanned array multifunction 3D radar (MFR) developed and manufactured by Thales Nederland. The radar receiver modules are developed and built in the US by the Sanmina Corporation.
The AN/SPS-48 is a US naval electronically scanned array, air search three-dimensional radar system manufactured by ITT Exelis and deployed in the 1960s as the primary air search sensor for anti-aircraft warships. The deployment of the AN/SPY-1 and the end of the Cold War led to the decommissioning of many such ships, and many of these vessel's AN/SPS-48 sets were reused on aircraft carriers and amphibious ships where it is used to direct targets for air defense systems such as the Sea Sparrow and RIM-116 SAM missiles. Existing sets are being modernized under the ROAR program to AN/SPS-48G standard for better reliability and usability.
USS Gray (FF-1054) was a United States Navy Knox-class frigate. She was named for Marine Corps Sergeant Ross F. Gray, who was a posthumous recipient of the Medal of Honor.
The Saab Giraffe Radar is a family of land and naval two- or three-dimensional G/H-band passive electronically scanned array radar-based surveillance and air defense command and control systems. It is tailored for operations with medium- and Short Range Air Defense (SHORAD) missile or gun systems, or for use as gap-fillers in a larger air defense system.
The AN/SPY-1 is a United States Navy 3D radar system manufactured by Lockheed Martin. The array is a passive electronically scanned system and a key component of the Aegis Combat System. The system is computer controlled and uses four complementary antennas to provide 360-degree coverage. The system was first installed in 1973 on USS Norton Sound and entered active service in 1983 as the SPY-1A on USS Ticonderoga. 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.
EMPAR is a rotating C band multifunction passive electronically scanned array radar that reached IOC in 2006 and was initially built by Selex ES. 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 information for missile guidance.
The EL/M-2248 MF-STAR is a multifunction active electronically scanned array naval radar system developed by IAI Elta for maritime installation on warships. It is capable of tracking both air and surface targets and providing fire control guidance. MF-STAR is an acronym of Multi-Function Surveillance, Track And Guidance Radar.
The EL/M-2258 ALPHA is a multi-function active electronically scanned array naval radar system developed by IAI Elta for maritime installation on medium-sized combat ships such as corvettes, frigates and larger vessels. It is capable of tracking both air and surface targets and providing fire control and splash spotting guidance with target classification. ALPHA is an acronym of Advanced Lightweight Phased Array Naval Radars.
ARV Mariscal Sucre (F-21) is the lead ship of the Mariscal Sucre-class frigate of the Venezuelan Navy.
ARV Almirante Brión (F-22) is the second ship of the Mariscal Sucre-class frigate of the Venezuelan Navy.
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.
