VIPER 100C – Unmanned Aerial System (UAS)

The Viper 100 is a long endurance, long range unmanned aircraft system designed for a professional use. 


Viper 100 Overview

The Viper 100 is a long-endurance, long range unmanned aircraft system designed for professional use. Its flight endurance of over 20 hours and operation radius of over 100 kilometres or 60 miles makes it an extremely productive unmanned platform in terms of distance travelled and area covered in a single flight. If equipped with advanced AMG camera payloads. Viper 100 is one of the most capable surveillance and inspection UAS available on the market.

The aircraft, operated by a crew of two, fits in a minivan, and it can be assembled in less than an hour. Its portable launcher and parachute recovery system allows for runway-independent operation and unmatched portability in its class.

The Viper 100 falls under the 25 Kg CAA regulation requirements for small UAVs. The aircraft is non-ITAR restricted, giving our global customers easy access to its capabilities.

The design of the system is based on the proven Viper airframe. The Viper 100 is powered by Ultimate Unmanned highly efficient Electronic Fuel Injected Gasoline Engine

The Viper 100  has been test flown for hundreds of hours to ensure its reliability and robustness in normal to severe weather conditions.

Class leading mobility

A crew of two can operate the Viper 100 UAS, and all the necessary equipment, including the pneumatic launcher, can be transported in a minivan and assembled in under an hour. The whole system, packed in several ruggedized containers, weighs up to 265 kilograms or 585 pounds.

The use of a sophisticated parachute/airbag recovery system eliminates the need for bulky equipment such as a landing net or landing wire and provides for a very soft landing, thus reducing the risk of damage to the aircraft or payload in case of both planned and emergency landings. In addition, the Viper 100 uses a proprietary algorithm that estimates the parachute landing point based on a number of flight conditions and allows for controlled aircraft recovery in a small designated area.

Highly efficient EFI long-endurance engine

Thanks to the Ultimate Unmanned state-of-the-art electronic fuel injected (EFI) engine, Viper 100 flight endurance exceeds 20 hours. The cooling system provides the ability to operate from below freezing point to extremely hot conditions.

The EFI engine comes built into a swappable propulsion module than can be changed in minutes, allowing for uninterrupted operation of the aircraft system while maintenance is performed on a second module.

Each engine is equipped with a Silent muffler with the lowest acoustic signature in this class of aircraft, and this makes the Viper 100 a very suitable platform for covert surveillance missions.

Leading cost efficiency

While the Viper 100 system provides the best in-class capabilities, it also comes at the lowest acquisition cost in its class and has the lowest operating cost. Additionally, its parachute/airbag landing system reduces the risk of payload, aircraft or third-party property damage in case of an unscheduled landing.
