India's Aeronautical Development Establishment (ADE) Rustom 1 unmanned air system is still undergoing testing and recently completed its 14th successful flight.
In a statement, India's government said the 14th flight achieved two milestones: the heaviest take-off weight of 690kg (1,520lb) since testing began in November 2009; and the farthest flight from base thus far, 50km (27nm).
The flight took place from a location in India's southern Karnataka province on 8 May. It lasted 2h and 10min, with the Rustom 1 reaching a top speed of 75kt (140km/h) and altitude of 11,500ft (3,500m).
