Indian Air-force planing to upgrade its fleet of Sukhoi-30MKI fighter jets with more advanced avionics, radars and weapons to further bolster their combat capabilities, with detailed talks currently under way with Russia for the project.

New Indian Air Force Chief Air Chief Marshal Rakesh Kumar Bhadauria has plans to upgrade the Sukhoi-30MKI with modern “radar and weapons capabilities and also enhance features that tackle obsolescence management and electronic warfare aspects”,

The Indian Air Force fleet of Su-30MKI fighter jets will undergo an upgrade and include more modern weaponry, an AESA radar and advanced avionics. The IAF operates around 240 of these fighters and another 32 are in the pipeline for delivery. “Hope the upgrade starts soon,” said Air Marshall SB Deo, VCAS, at an event organised by HAL to mark 70 years of India-Russia diplomatic relations.The upgrade shall include long-range standoff missiles  up to the range of 300 km and more powerful electronic jamming systems.Concerning the fifth generation fighter aircraft (FGFA), Chairman HAL stated that the multi-billion dollar co-development project with Russia “would be an opportunity as no country had ever offered such critical technology to India”.

An Air Force Veteran and senior defence analyst said the upgraded radar would likely be the NIIP N035 Irbis E (Snow Leopard), a 20 KW class steerable hybrid ESA radar fitted on the Su-35.

“At full power, the radar can detect an F-35 at a distance of 58-km (36-mi), In tracking mode, the distance drops to 29km,” Vijainder K Thakur, Air Force veteran and defence analyst having hawk eyes on technological development said.

Designed by the Tikhomirov Scientific Research Institute (NIIP) in Moscow’s Zhukovsky city, the Irbis-E is a direct evolution of the BARS design, all-weather multimode airborne radars of a Russian family, but significantly more powerful.

The radar is cited at an average power rating of 5 kilowatts, with 2 kilowatts CW rating for illumination. The NIIP claim twice the bandwidth and improved frequency agility over the BARS, and better electronic counter-countermeasures capability.

However, Harsh Vardhan Thakur, an experimental test pilot said: “When defining pick up and rack ranges for the F-35, the low-observability may have been exaggerated. I think F-35 can be picked up at larger ranges, just as a J-20 can.”

It is expected that upgrading the Su-30MKI will not take much time as Russia already implemented significant upgrades including radar and engines on the Su-30SM which is in the service of the Russian Air Force.

Vijainder K Thakur said Russia had integrated Su35 IRBIS-E Radar and AL-41F-C1 engines on a Su-30 airframe with the Su-30SM, which represents a convergence of the two platforms independently developed from the Su-27, aimed at mitigating logistics & maintenance overheads.

In 2018, Indian Air Force Sukhoi Su-30MKI reportedly managed to detect the latest Chinese Chengdu J-20 jet fighter, supposed to be a top-of-the-line stealth aircraft operated by China’s People’s Liberation Army Air Force (PLAAF). J-20 fighter jets, as claimed by China, are made up of radar-absorbing materials that are supposed to make it hard to detect at long ranges.

Earlier this month, the German radar-maker Hensoldt claimed that it managed to track two American made F-35s from a pony farm for almost 100 miles (about 150 km) during an air show, the C4ISRNet website reported.

  1. Fine , Good idea to have special radar to track radar evading planes.
