Defence forces believe that terrorists operating in Jammu and Kashmir are in possession of shoulder-fired missiles that can target planes, a top Indian Air Force official said in Srinagar on Thursday.

"There is a threat and a persistent one on this account," IAF's Air Officer Commanding-in-Chief, Western Air Command, Air Marshal A R Gandhi said.

He said although such missiles have not been used so far, IAF was taking all necessary precautions to ensure safety.

"We have evolved procedures and are using protective devices to ensure safety of our planes," Air Marshal Gandhi said.

On the recent move to acquire Hawk advanced jet trainers, he dispelled doubts over their efficacy and said: "We are getting what we asked for."

"Technology is constantly improving in the world and if necessary, technology of these AJTS can also be upgraded after
induction," he said.
