The Yarará project is the first unmanned aerial vehicle (UAV) programme in South America to be produced in series and for export. The system is developed by Nostromo Defensa for surveillance, border patrol and reconnaissance. It was unveiled at the Air Show of the Argentine Air Force (Fuerza Aérea Argentina, FAA) on 10 August 2006. The manufacturer says it has been produced in small series for export to an unidentified government customer in the United States.

Technical specifications (as reported by manufacturer): Payload capability: 5 kg, Endurance: 4 Hrs, Wingspan: 4 Mts, Engine: 5.5 Hp gas-propelled, Range: 20 km, Cruise speed: 100 km/h

The vehicle was named after the yarará, a South American snake.

Currently the Yarara UAV is being upgraded to use an advanced Wankel engine, running on heavy fuel with electronic injection. This engine is being developed by the British company Cubewano Ltd.
