Indian Air Force UAV

An unmanned aerial vehicle (UAV) is an aircraft without a human pilot on board and a type of unmanned vehicle. UAVs include a ground-based controller, and a system of communications between the two. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator, autonomously by onboard computers or piloted by an autonomous robot.

1. IAI Searcher

The IAI Searcher is a reconnaissance UAV developed in Israel in the 1980s. In the following decade, it replaced the IMI Mastiff and IAI Scout UAVs then in service with the Israeli Army.

In addition to Israel, the system had been exported and is currently in use by Russia, India, South Korea, Sri Lanka, Singapore, Thailand and Turkey.

2.  IAI Harop

The IAI Harop is a loitering munition developed by the MBT division of Israel Aerospace Industries. It is an anti-radiation drone that can autonomously home in on radio emissions. Rather than holding a separate high-explosive warhead, the drone itself is the main munition. This SEAD-optimised loitering munition is designed to loiter the battlefield and attack targets by self-destructing into them.The drone can either operate fully autonomously, using its anti-radar homing system, or it can take a human-in-the-loop mode. If a target is not engaged, the drone will return and land itself back at base.

3.  DRDO Lakshya

The drone remotely piloted by a ground control station provides realistic towed aerial sub-targets for live fire training. The drone is ground or ship launched from a zero length launcher and recovery is by a two-stage parachute system developed by ADE (DRDO), for land- or sea-based recovery. The drone has a crushable nose cone, which absorbs the impact of landing, minimizing damage. The flight path may be controlled or pre-programmed, based upon the type of mission.

4. AI Heron 

The IAI Heron is a medium-altitude long-endurance unmanned aerial vehicle (UAV) developed by the Malat (UAV) division of Israel Aerospace Industries. It is capable of Medium Altitude Long Endurance (MALE) operations of up to 52 hours' duration at up to 10.5 km (35,000 ft). It has demonstrated 52 hours of continuous flight, but the effective operational maximal flight duration is less, according to payload and flight profile. An advanced version, the Heron TP, is also known as the IAI Eitan.
