The Vrabac (from Serbian: врабац, lit. 'sparrow') is a mini drone intended for day/night reconnaissance and surveillance at shorter distances, as well as for target finding and designating, produced in Serbia by Utva Aviation Industry, subsidiary of Yugoimport SDPR.[1]

Design

The VRABAC is a high-wing monoplane made of composite materials. Its fuselage is aerodynamically shaped around the equipment. The nose part contains an 800W DC motor powered by a Li-pol battery while the space below and behind it is intended for electro-optical equipment. The airborne computer is in the central part. The UAV is hand launched and lands with a parachute and an airbag. It is designed to survey and analyze major infrastructural facilities such as pipelines, major roads, bridges, forests, etc.

In 2022, an armed version was revealed that can be equipped with six 40 mm M22 munitions.[2]
