The Indian Naval Air Arm is part of the Indian Navy which is tasked to provide an aircraft carrier based strike capability, fleet air defence, maritime reconnaissance, and anti-submarine warfare. To undertake these tasks, the Indian Navy employs an aircraft carrier and a variety of manned and unmanned aircraft and helicopters. The INS Viraat carries a complement of Sea Harrier aircraft and Kamov, Sea King, Chetak and Dhruv helicopters. The Kamov Ka-31 provides AEW support for the fleet. In the anti-submarine role, the Sea King, Ka-28 and the indigenously-built HAL Dhruv are used. The MARCOS use Sea King and HAL Dhruv helicopters while conducting operations. Reconnaissance operations are carried out by Tupolev Tu-142s, Ilyushin Il-38s, Dornier Do 228s and also by HAL Chetak helicopters. The UAV arm consists of around 30 UAVs, such as Heron and Searcher-IIs, that are operated from ships and shore for better surveillance. The Indian Navy also maintains an aerobatic display team, the Sagar Pawan. The Sagar Pawan team will be replacing the present HJT-16 Kiran with the HJT-36. The HJT-36 will also be used in training pilots.
