India’s mini-AWACS are being developed with the capability to receive fuel mid-air. This will enhance the aircrafts’ endurance and allow them to remain longer in the air. The Brazilian Embraer – 145 jets are being modified as per demands of the Indian Air Force, S Christopher, secretary, Department of Defence R&D and director general, Defence Research & Development Organisation (DRDO), said in Kolkata on Thursday.
The IAF already operates Phalcon-mounted IL-76 Airborne Early Warning & Control (AEW&C) Systems. Apart from these, three Embraer jets are being fitted with AEW&C systems by the DRDO to operate as mini-AWACS. While the IL-76 carry sufficient fuel to remain airborne for hours at a time, the Embraers don’t have that kind of endurance, hence the need to add the facility for mid-air refuelling.
“There are only four countries in the world that have developed AEW&C systems. We are one of them. Fundamental research takes time, even in advanced countries. There are reasons for delay in the development of products. Sometimes, there are miscalculations and people are not aware of the complexities when fixing deadlines. At times, users want modifications at the last stage. This is what has happened with the Embraers. Lastly, there are certain certification processes that take time. The Prime Minister’s Make in India policy has come as a boon for DRDO. We are keenly looking out for exports. Even if a big company with 100% Foreign Direct Investment comes in, we are ready to face the competition,” Christopher said.
DRDO develops some weapons systems that can operate in sub-zero temperatures as well as extremely hot climates.
According to the DRDO DG, there are several countries where these systems are in high demand. In some cases, the tolerance levels need not be so extreme. For example, countries closer to the equator may not require systems with capabilities to operate in sub-zero temperatures. Our own military establishment has faith on us. That is why they have placed orders worth Rs 2.51 lakh crore with DRDO.
Christopher, when asked, admitted that problems still persist with the Nag anti-tank guided missile that was to undergo its final user acceptance trials by the Army in the next few days. According to the DG, there are problems with the missile’s seeker system.
“The missile operates on a temperature differential system. It distinguishes between a tank and its surroundings based on the temperature difference. During midday, the missile is not being able to find its target as there is little difference between temperatures. For the time being, we have asked the Army to reduce its range from 4 km to 3.2 km during midday trials,” Christopher said.
