Rustom II Medium-Altitude Long-Endurance (MALE) drone has been developed by India’s DRDO and is part of the Rustom class of drones built by India

India’s Defence Research and Development Organisation successfully completed the test flight of its Rustom 2 drone at the Aeronautical Test Range. Rustom 2 is part of the Rustom line of Unmanned Aerial Vehicles (UAVs) that includes Rustom-I, Rustom-H and Rustom-C.

The drone was developed for use by all three services of the Indian armed forces, primarily for intelligence, surveillance and reconnaissance (ISR) operations. The medium-altitude prototype can fly at over 22,000 ft and is a long-endurance UAV that has an approximate flight time of 20 hours.

The drone has been modelled on the Rustom-H UCAV with a light airframe. The Rustom 2 is propelled by two 3-bladed NPO saturn engines. It stands 2.4 metres tall with a wingspan of 20.6 metres and a length of 9.5 metres. The UAV’s tail section comes with a T-type vertical stabiliser and a high-mounted horizontal tailplane.

It can fly at around 280 km/h and carry a variety of payloads like Medium Range Electro Optic (MREO), Long Range Electro Optic (LREO), Synthetic Aperture Radar (SAR), Electronic Intelligence (ELINT), Communication Intelligence (COMINT) and Situational Awareness Payloads (SAP) that help in performing missions even during the night. MREO and LREO sensors are placed inside a modular payload under the nose for capturing imagery and video.

The drone’s data link developed by Defence Electronics Application Laboratory transmits the ISR data to the armed forces’ ground control station in realtime allowing prompt action.

Rustom-2 can fly missions on manual as well as autonomous modes. The onboard way-point navigation system allows the drone to conduct missions autonomously. The two NPO Saturn MT turboprop engines are fitted under the wings and produce over 450 kilogram-force thrust each.

Several critical systems and components of the drone, like its airframe, avionics sub-systems, flight control, landing gear etc have been made indigenously and some in collaboration with private manufacturers.
