Extremely instructive thread on the evolution of the doctrine of the utility of drones in the services, the R&D involved, the various programs afoot & the likely procurement schedules..
Do note that this is a civilian writing. Someone who believes in talking to & not down to his audience. Someone who has also come up with extremely good write ups in the past in the public domain on our various air force programs which in turn have been favourably reviewed by ex & serving service personnel. Someone whose writing isn't 1/4 part knowledge & 3/4 parts wishful thinking + optimism.
The Indian Army has leased four Heron Unmanned Aerial Vehicles (UAV) from Israel as part of its emergency procurement programme. The Heron, with the Indian Army for some years, can be particularly effective in intelligence gathering as it is a long-endurance UAV and can be in the air for about 50 hours at a time.
