Lakshya ("target" in Sanskrit) is an Indian remotely piloted high speed target drone system developed by the Aeronautical Development Establishment (ADE) of DRDO. A variant Lakshya-1 is used to perform discreet aerial reconnaissance of battlefield and target acquisition.

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.

The requirement for a pilotless target aircraft (PTA) arose in 1976. Feasibility studies were carried out by ADE to provide for a target system that met the requirements of all 3 services of the armed forces. An Inter Services Qualitative Requirement (ISQR), common to the three Services, was formulated by a Working Group constituted by the Ministry of Defence in January 1977 and 35 ISQR points were identified. Subsequently, based on a feasibility study carried out by ADE, the project for the design and development of Inter-Services PTA by ADE, satisfying the ISQR was sanctioned by Government in September 1980 at a cost of ₹170 million (US$2.6 million) including a foreign exchange element of ₹80 million (US$1.2 million). The development activity was planned for completion within five years. In parallel, a development project for indigenous development of PTA Engine (PTAE-7) was also sanctioned at an estimated cost of ₹45 million (US$696,276.00) to Hindustan Aeronautics Limited (HAL) in September 1980, based on a feasibility study and project proposal submitted by HAL. The engine was to be developed by HAL by September 1985, concurrently with the PTA. HAL announced the successful trial of the indigenously-designed and developed remote-controlled PTAE-7 jet engine on 24 January 2001.

Between December 1985 and July 1986, four Lakshya PTA prototypes powered by Microturbo TRI-60-5 engines were launched for trials. While the first two launches were successful for planned flight times of 20 and 38 minutes respectively, the next two launches failed. By June 1994, 18 Lakshya PTA prototypes were fabricated by ADE itself and 43 trials were conducted, 24 of which were between December 1985 and February 1992. Due to rigorous evaluation and stringent quality control, a total of 10 prototypes were lost during the testing phase between 1985 and 1990. The project was formally closed on June 1994 and a final closure report was issued in April 1995 after incurring a total expenditure of ₹218.2 million (US$3.4 million). The first 6 Lakshya drones were given to the Indian Air Force in 1998. Laskhya units are manufactured and overhauled at HAL's Aircraft division, Bangalore. The Lakshya was formally inducted into the services by CAS AY Tipnis, on 9 November 2000 at Interim test range (ITR) Chandipur. On 9 May 2002, an upgraded version of the Laskhya featuring the new engine from HAL was flown from ITR Chandipur, bringing user trials to a close. On 6 November 2002, HAL announced that they had received an initial order for 25 Lakshya drones and that limited series production to satisfy the order for all three services had already begun. By 16 January 2003, the drone had completed over 100 flights.
