LCA Tejas Mk 1A gets Israeli EL/M-2052 AESA Radar

The home grown Light Combat Aircraft (LCA) is set to be equipped with Israeli super radars that will give it the combat edge to engage multiple air and ground targets simultaneously. Israeli firm ELTA is likely to shortly bag an order for a new set of AESA (Active Electronically Scanned Array) radars for an air force order of 83 LCA Mk 1A jets.
The Israeli firm appears to have beat off competition from French firm Thales for the contract that has been in the works since 2016. Sources said that advanced negotiations are now on to finalise the contract at the earliest for early delivery of the combat enhanced jets to the Indian Air Force.
The ELTA radar is a derivate of the EL/M-2052 Active Electronically Scanning Array (AESA) that has also been equipped onboard the Jaguar DARIN III fighter jets of the air force. It has been selected for the LCA program ahead of the French Thales RBE2 radar derivative. Earlier, other suitors including the Americans and Swedes dropped out of the competition.
The integration of an AESA radar is a pre requisite to the air force order that also mandates equipping the fighters with beyond visual range missiles and an electronic warfare suite. The radars give much more range and engagement potential to fighters, enabling them to engage targets from a distance without getting detected. The AESA will give the LCA an edge over fighter of a similar weight category that are operating in the region with conventional radars.
The Jaguar DARIN III is India’s first fighter jet to be equipped with AESA radars with 58 of them being integrated currently onto the fleet. The deep penetration fighter fleet got a big upgrade with the new radars, significantly increasing the air force’s capability to carry out cross border strikes.
AESA radars have replaced conventional systems at the heart of all modern fighter aircraft – be it the Dassault Rafale and Boeing F/A 18 other than fifth generation jets like the F 22 and F 35.
Hindustan Aeronautics Limited (HAL) conducted the maiden flight of the first SEPECAT Jaguar DARIN III equipped with an Elta EL/M-2052 active electronically-scanned array (AESA) radaron August 10.
The DARIN (Display, Attack, Range and Inertial Navigation) III is an upgrade of the SEPECAT Jaguar, which serves as one of the Indian Air Force’s (IAF) mainstay strike aircraft.
The DARIN III comprises of upgrades to the Jaguar’s electronics systems. These include open system architecture mission computer, multi-functional displays, engine and flight instrument system, new fire control radar, geodetic height correction system and inertial navigation system with satellite navigation.
Wort $520 million U.S., HAL was to implement DARIN III onto 61 IAF Jaguars by the end of 2017. However, the program is behind schedule and will likely conclude in 2022. The IAF awarded initial operational clearance (IOC) to the Jaguar DARIN III in November 2016.
Already a valuable strike asset, the inclusion of the EL/M-2052 provides the Jaguar DARIN III with improved defensibility against electronic warfare jamming. By virtue of having multiple transceiver modules (TRM), each transmitting in a different radio frequency, the EL/M-2052 also has a lower probability-of-intercept with enemy radar warning receivers. The Jaguar DARIN III would be more difficult to detect and to jam.
Otherwise, EL/M-2052 is an advanced multi-mode radar capable of air-to-air, air-to-ground and air-to-sea tracking, targeting and engagement. Elta has not disclosed the radar’s range or the number of targets it can track and simultaneously engage.
The IAF has configured the SEPECAT Jaguar to deploy a wide range of munitions, among them the AIM-132 Advanced Short Range Air-to-Air Missile and the CBU-105 Sensor-Fuzed Weapon. The latter is a highly capable anti-armour weapon comprising of a total 40 dual infrared and laser-guided top-attack Skeets. Each Skeet can independently target and engage tanks and other armoured vehicles.
LM-2052 – Active Electronic Scan Array Airborne Fire Control Radar
General
The ELM-2052 is an advanced Fire Control Radar (FCR) designed for air-to-air superiority and strike missions, based on fully solid-state Active Ellectronically Scanning Array (AESA) technology, enabling the radar to achieve long detection ranges, high mission reliability and multi-target tracking capabilities.
The ELM-2052 radar provides simultaneous modes of operation supporting multi-mission capabilities for air-to-air, air-to-ground and air-to-sea operation modes, and weapon deployment.
In the air-to-air mode, the radar delivers very long-range multi target detection and enables several simultaneous weapon deliveries in combat engagements.
In air-to-ground missions, the radar provides very high resolution SAR mapping, surface moving target detection and tracking over RBM and SAR maps in addition to A/G ranging.
In air-to-sea missions the radar provides long-range target detection and tracking, including target classification capabilities (RS, ISAR).
The ELM-2052 radar design reflects ELTA’s vast field-proven radar experience and operational feedback received from Israeli Air Force fighter pilots.
