The E1 Gavilán ('Sparrowhawk' in English) is an unmanned electrical-surveillance airplane designed and manufactured by the Mexican firm Hydra Technologies.

[1] The Gavilán was unveiled on June 10 2008, at the Association for Unmanned Vehicle Systems International (AUVSI) North America 2008 event in San Diego, California[citation needed].

The Gavilán is a multipurpose reusable unmanned aerial system for surveillance.

The plane's main feature is that it does not rely on a runway for takeoff, making it easier to maneuver on uneven terrain by the help of manual control[citation needed].

The system was developed by the Mexican Federal Government, Nafinsa and academic or scientific institutions such as CONACYT, Instituto Politécnico Nacional, Universidad Autónoma de Guadalajara and ITESO[citation needed].
