India catching up with advances in UAVs.


India is looking to beef up its domestic capabilities by rapidly developing a fleet of unmanned aerial vehicles

Main article: Unmanned aerial vehicle
The following is a list of Unmanned aerial vehicles developed and operated by various countries around the world. Listed with primary mission(s) and year of first flight.
. The slow development of indigenous UAVs forced India to drop around $300 million to purchase the Heron and Searcher-II systems from Israel in 1999, during a tense standoff with Pakistan.

Most recently, the Indian Defence Research and Development Organisation announced it is charging ahead with the development and deployment of the domestically-produced Nishant and Lakshya drones.

Lakshya is a subsonic sub·son·ic  
adj.
1. Of less than audible frequency.

2. Having a speed less than that of sound in a designated medium.


subsonic
Adjective
 reusable target aircraft, powered by a gas turbine. It already is employed in the Indian Air Force The Indian Air Force (भारतीय वायु सेना : Bharatiya Vayu Sena) is the air-arm of the Armed Forces of India and has the prime responsibility of conducting aerial warfare and securing the , Army and Navy to train land or ship-based gun and missile crews in weapons engagement.

With rocket-assisted take-off, Lakshya can reach altitudes of 100 km. It can be recovered by parachute. It can be reused for 15 missions. A hybrid autopilot provides pitch, roll and yaw yaw, in aviation: see airplane; airfoil.


See pitch-yaw-roll.
 control in flight.

The Lakshya target vehicle will be the basis for the development of a subsonic cruise missile--one of the futuristic projects planned to start this year.

Nishant has been developed for battlefield surveillance and reconnaissance, and has a gimbaled payload assembly with control mechanism in azimuth and elevation. A pusher pusher Drug slang 1.

It has autonomous flight capabilities at longer ranges, as well as jam-resistant digital command and downlink. The vehicle can be recovered with a combination of parachute and landing bags. It will be used for day and night reconnaissance, surveillance, target acquisition and correction of artillery fire. Nishant can detect human beings out to 2.5 km, trucks at 5 km and buildings at 12 km. It can fly as fast as 150 km an hour.

The Nishant is connected to a ground control station by a fiber-optic link. The GCS consists of an electronic map display, mission-planning tools, simulator for pilot training and remote control of antenna system.

India is expected to soon start the development of a long-endurance UAV, multi spectral stealth materials and an autonomous underwater vehicle | An Autonomous Underwater Vehicle (AUV) is a robot which travels underwater. Sometimes called Unmanned Underwater Vehicles, these devices are powered by batteries or fuel cells and can operate in water as deep as 6000 meters. , according to DRDO.
