The IAI EL/W-2090 is an airborne early warning and control (AEW&C) radar system developed by Israel Aerospace Industries (IAI) and Elta Electronics Industries of Israel. Its primary objective is to provide intelligence to maintain air superiority and conduct surveillance. The system is currently in-service with the Indian Air Force. [1]
It is a development of the EL/M-2075 system, described by the Federation of American Scientists as the most advanced AEW&C system in the world in a 1999 article. [2]
The EL/W-2090 is a further development of EL/M-2075 and EL/W-2085.
The EL/W-2090 uses an active electronically scanned array (AESA), an active phased array radar. This radar consists of an array of transmit/receive (T/R) modules that allow a beam to be electronically steered, making a physically rotating radome unnecessary. AESA radars operate on a pseudorandom set of frequencies and also have very short scanning rates, which makes them difficult to detect and jam.
In March 2004, as a part of a tri-partite deal among Israel, India, and Russia, Israel and India signed a US$1.1 billion deal according to which IAI would deliver the Indian Air Force three AEW&C radar systems, each of which was worth approximately $350 million. [3] [4] India signed a deal with Ilyushin of Russia for the supply of three Il-76 A-50 heavy airlifters, which were to be used as platforms for these radar systems, for an additional US $500 million. The first aircraft was delivered to India on 25 May 2009, landing at Jamnagar AFS in Gujarat, completing its 8 hour long journey from Israel. [5]
In November, 2016, India signed another deal to purchase two more AEW&C radar systems to purchase two additional systems for $1-1.4 billion, with scheduled within the next 3 years. [6] [7] As of end 2023, India has three EL/W-2090 systems in service. [8] [9]
In 1994, Israel entered into talks with China regarding the sale of the Phalcon radar system, initially for four units but with an understanding that as many as eight would be procured. [10] An agreement between China and Israel was signed in July 1996. Russia entered the program in March 1997; the first Il-76 slated for modifications landed in Israel in October 1999. [10] Although the US government was aware of the sale, it remained silent until October 1999, when it publicly opposed the sale of the EL/W-2090 to China. Fearing that the system would alter the military balance in the Taiwan Strait, American officials threatened to withhold aid to Israel in April 2000 if the deal proceeded. [10] [11]
On 12 July 2000, Prime Minister Ehud Barak announced that Israel would scrap the deal. [11] However, it was not until July 2000 when a formal letter was sent to the Chinese government; the Israeli government hoped that the newly elected Bush administration would endorse the Phalcon deal. [10] In March 2002, Israel concluded a $350-million compensation package to China, more than the $160-million advance payment China had already made. [10] Subsequently, the original Chinese KJ-2000 AEW&C entered service in 2004.
An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack aircraft. AEW&C units are also used to carry out aerial surveillance over ground and maritime targets, and frequently perform battle management command and control (BMC2). When used at altitude, the radar system on AEW&C aircraft allows the operators to detect, track and prioritize targets and identify friendly aircraft from hostile ones in real-time and from much farther away than ground-based radars. Like ground-based radars, AEW&C systems can be detected and targeted by opposing forces, but due to aircraft mobility and extended sensor range, they are much less vulnerable to counter-attacks than ground systems.
The Boeing E-7 Wedgetail, also marketed as the Boeing 737 AEW&C, is a twin-engine airborne early warning and control aircraft based on the Boeing 737 Next Generation design. It has a fixed, active electronically scanned array radar antenna instead of a rotating one as with the 707-based Boeing E-3 Sentry. The E-7 was designed for the Royal Australian Air Force (RAAF) under "Project Wedgetail" and designated E-7A Wedgetail.
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).
The Embraer R-99 is the Brazilian Air Force (FAB) military designation of the EMB-145-RS. Various models of the aircraft have been produced to perform special mission duties, including the E99 for airborne early warning and control (AEW&C) missions, the R-99 for remote sensing, and the P-99 for maritime patrol.
