The IAF formed its first dedicated EW Squadron equipping No 35 Squadron with Canberras and MiG-21 aircraft with stand-off and escort jammers respectively. Jaguars were the next to get the ‘Dawn’ podded jammer. With the Mirage-2000 came the first dedicated EW suite that included the Thales Serval internal RWR, internal ABD-2000 ASPJ, Remora podded ASPJ, Caiman Escort jammer and the Syrel ELINT pod. SU-30 MKI too has a comprehensive EW suite that includes OLS-30 laser-optical IRST with day-and-night FLIR capability which enables engagement of the target even when partly obscured by clouds or countermeasures; the Tarang RWR developed by DRDO and the Elta EL/M-8222 self-protection jammer developed by Israel Aircraft Industries with an ESM receiver integrated into the pod.
India’s DRDO labs are working on a host of EW Systems for application on airborne, space-based and surface systems. Most indigenous EW systems developed by DRDO included Dawn, Tempest, Tarang, CMDS, Samyukta, COIN for various fighter aircraft such as MIG 21, MIG 23, MIG 27 Jaguar, Su-30, Sea Harrier and LCA had limited success. Bharat Electricals Limited (BEL) produces most indigenous EW systems. MiG-29 and Su-30 MKI need upgrade of their EW suite. EW suite of Light Combat Aircraft Tejas and Light Attack Helicopter (LAH) are still evolving. DRDO’s Defence Avionics Research Establishment (DARE) EW suite completed first flight on Tejas-PV1 LCA early 2015.
The LCA will be fitted with unified radar warning and jamming system. The flight testing will take some time for the system to become operational. India’s Advanced Light Helicopter (ALH) Dhruv is equipped with a Swedish Saab EW suite. The Rafale will bring new EW technologies. It features an integrated system named SPECTRA developed jointly between Thales and MBDA, which protects the aircraft against airborne and ground threats. SPECTRA would allow Rafale to become independent of SEAD platforms. The effective radiated power (ERP) of the EL/M-2080 Green Pine radar, with India, makes it a possible candidate for conversion into a directed-energy weapon, by focusing pulses of radar energy on target missiles.
Indigenous EW Projects
DRDO’s Brazilian Embraer EMB-145 aircraft was chosen as the AEW&C platform and three aircraft purchased for $210 million. The first aircraft arrived on August 16, 2012. The IAF needs 24 such platforms. The aircraft will have Active Electronically Scanned Array (AESA) primary radar. The system will also have Electronic Support Measures (ESM) and Communications Support Measures (CSM) ability. There will be datalinks to network with the fighters, and ground-based control systems. Aircraft’s Self Protection Suite will have a passive Missile Approach Warning System, a Radar Warning Receiver and countermeasures dispensers. The DRDO and the Bengaluru-based Centre for Air Borne Systems (CABS) have also launched a new project to build larger and more capable AWACS. Initially, two AWACS aircraft will be developed, with four more to follow at a later stage. Clearances for the project were received from the government in January 2013.
In 2014, the Defence Acquisition Council (DAC) finally approved `1,100 crore for the IAF’s long awaited nine ‘Special Mission’ aircraft. These multi-mission aircraft with Signals Intelligence (SIGINT), aerial survey, target towing, and Communication Jamming (COMJAM) militarised business jets would replace the retired Canberra and Avro aircraft. This acquisition would meet airborne special-mission requirements currently serviced by a small fleet of Gulfstream III SRA ELINT jets operated by the country’s external intelligence agency, R&AW. Embraer and IAI may be the main contenders. Embraer would pitch for advantage of commonality with DRDO AEW&C and IAI may offer more affordable Gulfstream G200/280 which it manufactures under license in Israel. US Hawker Beechcraft with Raytheon L-3 communications and Lockheed Martin or Boeing systems could also be in the race. The IAF is also looking for systems that merge cyber and EW techniques akin to US next generation jammer. Israeli Elbit Systems EW and SIGINT Company ‘Elisra’which provides comprehensive solutions in the electromagnetic spectrum domain is working closely with BEL and Private sector Samtel Group for aircraft EW systems. All aircraft have to be capable of operating from airfields located up to an altitude of 10,000 ft such as Leh and Thoise.
India’s Indigenous Synthetic Aperture Radar (SAR) developed by DRDO’s Electronics & Radar Development Establishment (LRDE) for Unmanned Aerial Vehicles (UAVs) is reportedly progressing well and may be flight tested by early 2017 on a modified Dornier Do-228. LRDE’s SAR is planned to be integrated with India’s Rustom-2 which is Medium Altitude Long Endurance (MALE) UAVs at later stages. LRDE is also planning to develop a derivate of this radar for operations from manned reconnaissance aircraft including a maritime variant. L&T CASSIDIAN Ltd is working on Tactical Radar for Ground Surveillance (TRGS) system that utilises AESA technology for ground surveillance missions.
Samyukta is an ambitious mobile integrated EW system developed jointly by DRDO, BEL, ECIL and Corps of Signals of the Indian Army that includes ELINT, COMINT and electronic attack. The Indian tri-services Defence Communication Network (DCN) would give ‘jointness’ to connectivity and will be the backbone of the proposed joint commands for cyber warfare, Special Operations and space operations.
