Lakshya

The Lakshya is a remotely piloted high-speed target drone developed by the Aeronautical Development Establishment (ADE) of the DRDO. The Indian military established a Pilotless Target Aircraft (PTA) requirement in 1976, leading to a joint Inter Services Qualitative Requirement in January 1977. The development project was sanctioned in September 1980. Concurrently, Hindustan Aeronautics Limited (HAL) was tasked with developing the PTAE-7 turbojet engine, which completed trials in January 2001. Between December 1985 and July 1986, four prototypes powered by Microturbo TRI-60-5 engines were flight-tested. By June 1994, ADE fabricated 18 prototypes and conducted 43 trials, losing 10 prototypes during testing. The first six units were delivered to the Indian Air Force (IAF) in 1998, and the system was formally inducted on November 9, 2000. HAL began limited series production in 2002 to satisfy an initial order for 25 drones.

Design

The drone is 2.385 meters long, has a wingspan of 5 meters, and has a maximum takeoff weight of 705 kg. It uses a NACA 64 A 008 airfoil. The aircraft is launched from ground- or ship-based zero-length launchers with rocket assistance and is recovered via a two-stage parachute system. A crushable nose cone minimizes landing damage. Propulsion is provided by a 3.73 kN HAL PTAE-7 turbojet engine, yielding a maximum speed of Mach 0.7, a range of 150 km, and a ceiling of 9,000 meters (5,000 meters when towing targets). The flight path is controlled via a ground control station or pre-programmed, deploying towed aerial sub-targets for live-fire training.

Operational History

The IAF received its first systems in September 1999. A total of 23 Lakshya drones have been inducted into the defense services, with allocations listing 15 units for the IAF, 5 for the Indian Navy, and 10 for the DRDO. Unit production cost is 29.375 million Rupees ($450,000). In 2002, a paid demonstration was conducted for the Israeli Air Force, and Singapore, Malaysia, and Israel have expressed interest in similar target demonstrations.

Variants

• Lakshya-1: A target and reconnaissance variant used for target acquisition and battlefield reconnaissance, with some IAF units upgraded with digitally controlled engines.

• Modified Reconnaissance Version: A development variant configured with oblique cameras and a digital onboard computer with a high-speed data link for autonomous operations.

• Lakshya-2: An advanced variant designed to simulate low-level cruise missiles by flying at sea-skimming altitudes down to 12 meters, featuring waypoint navigation, GPS recovery, and dual-target control from a single ground station.
