Watch: IAF's Sukhoi fighter jet refuel mid-air during Gagan Shakti 2018 exercise

Kalaikunda (West Bengal): In a bid to showcase its strength, reach and preparedness, the Indian Air Force (IAF) carried out an air-to-air refuelling display.

A video showed pilots performing the mid-air refuelling of a Sukhoi fighter jet during the Gagan Shakti 2018 exercises.

A Sukhoi Su-30 jet that took off from Kalaikunda airbase in West Bengal's Kharagpur engaged multiple targets over the area of Lakshadweep before it returned. The Sukhoi jet was refuelled twice mid-air. It was refuelled once on its way towards Lakshadweep and during the return flight after the mission.

IAF has mobilised 1,100 aircrafts, including fighters, transports and helicopters for Gagan Shakti 2018. Close to 4,000 sorties have been planned through the day and night across the length and breadth of the country. Simulated strike missions by IAF fighters also extend deep into the Indian Ocean.

The air-to-air refuelling methodology practiced by IAF pilots requires exceptional flying skills as the receiving aircraft has to accurately insert the receptacle probe into the basket shaped drogue trailing behind the fuel tanker aircraft.

During the process of such refuelling, both aircrafts have to maintain extremely accurate flying parameters.

Gagan Shakti 2018 will revolve around two phases. The first phase will see operations along the western border for which the government of Pakistan has been given prior intimation.

The next phase will see the flights along the northern border and will also see operations at high-altitude air landing grounds which have been constructed with an eye on Chinese defences on the Tibet front.

The key to the overall success of Gagan Shakti will be maintainability of the fleet or the ability of the IAF to successfully launch as many aircraft as possible, whenever they are required with minimal failure rates in between missions.
