Under the ambitious Project Cheetah, the Indian Air Force wants to upgrade its existing fleet of Israeli-origin Heron unmanned aerial vehicles with better communication facilities and missiles which can target enemy positions from long range.
A Heron Unmanned Aerial Vehicle of the Indian Air Force, used for surveillance, crashed on Wednesday on the outskirts of a village near Bhuj town in Gujarat's Kutch district.

The army has about 200 UAVs, mostly the Searcher 1, Searcher 2 and Heron supplied by Israeli Aerospace Industries, but security experts feel mini-UAVs will give troops an edge in operations against militants.
UAVs are an intrinsic part of today's technology driven battlefield. Indians don't seem to be taking the challenge with the degree of urgency that is required, says Brigadier S K Chatterji (retd).
'If UAV technology is used by the adversary to target VIPs or strategic targets it would be a different ball game altogether,' says Group Captain Murli Menon (retd).
DRDO says it is working with the navy to fit the Rustom-1 with an Automatic Identification System that will identify Indian fishing vessels along the maritime boundary
