The Armed Forces of the Argentine Republic are the combined armed forces of Argentina. It is controlled by the Commander-in-Chief and a civilian Minister of Defense. In addition to the Army, Navy and Air Force, there are two security forces, controlled by the Ministry of Security, which can be mobilized on occasion of an armed conflict: the National Gendarmerie, a gendarmerie used to guard borders and places of strategic importance; and the Naval Prefecture, a coast guard used to protect internal major rivers and maritime territory.
HMS Sheffield was a Type 42 guided missile destroyer and the second Royal Navy ship to be named after the city of Sheffield in Yorkshire. Commissioned on 16 February 1975 the Sheffield was part of the Task Force 317 sent to the Falkland Islands during the Falklands War. She was struck and heavily damaged by an Exocet air-launched anti-ship missile from an Argentine Super Étendard aircraft on 4 May 1982 and foundered while under tow on 10 May 1982.
The Dassault-Breguet Super Étendard is a French carrier-borne strike fighter aircraft designed by Dassault-Breguet for service with the French Navy.
Rajendra is a passive electronically scanned array radar developed by the Defence Research and Development Organisation (DRDO). This acts as the Fire-control radar for Akash weapon system. It is a multifunction radar, capable of surveillance, tracking and engaging low radar cross section targets. It is a ground surveillance radar and is a great source of surveillance operating at frequency around 20 GHz. It is mainly used to track enemy's installations.
The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. The system offers instrumented detection at ranges on the order of 200 to 250 nautical miles and has a wide variety of interference and clutter rejection systems.
SMART-L is a long-range naval search radar introduced in 2002 by Thales Nederland, formerly Hollandse Signaalapparaten (Signaal).
An airport surveillance radar (ASR) is a radar system used at airports to detect and display the presence and position of aircraft in the terminal area, the airspace around airports. It is the main air traffic control system for the airspace around airports. At large airports it typically controls traffic within a radius of 60 miles (96 km) of the airport below an elevation of 25,000 feet. The sophisticated systems at large airports consist of two different radar systems, the primary and secondary surveillance radar. The primary radar typically consists of a large rotating parabolic antenna dish that sweeps a vertical fan-shaped beam of microwaves around the airspace surrounding the airport. It detects the position and range of aircraft by microwaves reflected back to the antenna from the aircraft's surface. The secondary surveillance radar consists of a second rotating antenna, often mounted on the primary antenna, which interrogates the transponders of aircraft, which transmits a radio signal back containing the aircraft's identification, barometric altitude, and an emergency status code, which is displayed on the radar screen next to the return from the primary radar.
A passive electronically scanned array (PESA), also known as passive phased array, is an antenna in which the beam of radio waves can be electronically steered to point in different directions, in which all the antenna elements are connected to a single transmitter and/or receiver. The largest use of phased arrays is in radars. Most phased array radars in the world are PESA. The civilian microwave landing system uses PESA transmit-only arrays.
The AN/TPS-75 is a transportable passive electronically scanned array air search 3D radar produced in the United States. It was originally designated the TPS-43E2. Although the antenna is a radically new design from the TPS-43, the radar van itself, which houses the transmitter, receiver processors, and displays is very similar to the older TPS-43E2. It is produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop Grumman.
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 P-40"Armour" or 1S12 is a 3-D UHF radar developed and operated by the former Soviet Union.
The AN/MPN is a mobile Ground-controlled approach radar first used during World War II. "MPN" is Joint Electronics Type Designation System nomenclature for (Ground) Mobile (M), Pulsed (P), Navigation aid (N).
Captain Roberto Curilovic is a former Argentinian Navy pilot. On 25 May 1982 in the Falklands War, he sank the transport ship Atlantic Conveyor with an Exocet AM.39 anti-ship missile.
The AN/TPS-44 is a transportable 2-dimensional air search radar produced in the United States originally by Cardion Electronics.
AN/TPS-70 is a mobile rotating S band phased array 3D radar produced by Westinghouse. It can track 500 targets, displaying target range, height, azimuth, identification friend or foe (IFF) information from an altitude of 0 to 100,000 feet to a maximum range of 240 nautical miles. It is the successor of the AN/TPS-43. The TPS-70 tactical radar provides reliability, sensitivity, and accuracy, even in the face of jamming and high-clutter conditions. It is being replaced by newer systems, but is still in service all around the world.
Aselsan EIRS (Early Warning RADAR System) is a new generation S-Band radar, developed for long range early warning purposes, with AESA and digital beamforming antenna architecture. The system developed by Turkish company Aselsan. In addition to air-breathing air targets, EIRS also has the ability to detect and track Ballistic Missiles and targets with stealth technology / low RKA from long range.
Army/Navy Transportable Pulse-Radar Search-32 (AN/TPS-32) was a three-dimensional, tactical long-range surveillance radar operated by the United States Marine Corps from the early 1970s through the early 1990s. Developed by ITT Gilfillan in Van Nuys, California, the radar was the primary sensor for the Marine Corps' Tactical Air Operations Center (TAOC) and was optimized to work in concert with the MIM-23 Hawk Missile System and the Marine Tactical Data System.
The SCR-602 also known as the AN/TPS-3, was a mobile, lightweight, medium-range, early-warning radar utilized by the United States and its allies during World War II. The radar was originally designed for use during the initial stages of an amphibious assault or military operation where its lightweight relative to other radar systems was a distinct advantage. Once larger radars such as the SCR-270 or AN/TPS-1 came online the SCR-602 could also be used to fill in gaps in radar coverage.
AN/SPS-6 is a two-dimensional radar manufactured by Bendix and Westinghouse Electric. It was used by the US Navy as a first-generation air-search radar after World War II, and was widely exported to allies. In addition, the improved AN/SPS-12 is the derivative types developed in other countries.
The AN/TPS-63 was a medium range, Two-dimensional, L band radar system utilized by the United States Marine Corps from the early 1980s until finally retired in 2018. This mobile radar was developed by Northrop Grumman and complimented the AN/TPS-59 long range radar by providing 360 degree, gap-filling coverage of low altitude areas. Because it was more mobile, the TPS-63 was also employed as the first radar ashore during amphibious operations until the larger and more capable AN/TPS-59 was established. The TPS-63 was used in combat operations during the Gulf War, the 2003 invasion of Iraq and subsequent operations in Iraq and Afghanistan. The TPS-63 was eventually phased out of service in 2018 as it was replaced by the AN/TPS-80 Ground/Air Task Oriented Radar.
