UAVOS Announces a New Generation S1-V300 MALE Unmanned Platform Prototype

UAVOS has successfully completed the S1-V300 Medium Altitude Long Endurance (MALE) Unmanned Aerial System (UAS) prototype designed to check basic aircraft systems. The advanced UAS model is based on the Saker MALE UAS design that achieved operational capability in 2020. The S1-V300 MALE UAS prototype is an upgrade to the unmanned system and features a new design and  a more powerful heavy fuel engine with 260 HP offering greater speed, payload, and endurance of 28 hours with a range of 4020 km.  

Work performed under UAVOS’ MALE UAS program using its proven Saker aircraft capabilities has enabled it to create a new generation S1-V300 MALE unmanned platform.
The aircraft features unique UAVOS’ avionics solutions and redundant flight control system,
which will enable the complex missions of the MALE UAS.
The improved S1-V300 prototype is equipped with both Line-of-Sight (LOS) and Beyond Line-of-Sight (BLOS) data link systems for over-the-horizon operations. Additionally, the aircraft may be integrated with multiple ISR sensors, including state-of-the-art Electro optical Infrared (EO/IR) cameras and a state-of-the-art Synthetic Aperture Radar (SAR) that offers all-weather, day/night performance for a wide-area search capability. Enhanced with unsurpassed ISR capabilities, the S1-V300 UAS will now be able to support a variety of overland and maritime Intelligence, Surveillance, and Reconnaissance (ISR) missions worldwide.

The S1-V300 MALE UAS next-generation capabilities combined with medium-altitude persistence make it an ideal platform to add with long-range RADAR, Signals Intelligence
(SIGINT),  communication relay payloads, and system of counter electronic warfare.

Additional retrofits include improved structural strength wings and extra hardpoints for
carrying external payload of 300 kg.

The S1-V300 MALE is an advanced Unmanned Aerial System prototype with fully
autonomous operation capability. It is equipped with automatic taxi-takeoff and landing
systems, satellite communication for extended range, and fully redundant avionics. The UAV is designed to operate in harsh environments and is adapted to perform in extremely hostile, dry and dusty ambient air. The aircraft features an 8,7 meters long fuselage, a 18,7 meters wingspan, is capable of flying at 220 km/h, and has an endurance of over 28 hours. 

“We pride ourselves in rapidly designing, developing and launching advanced UAS thus
contributing to growing the unmanned systems industry. Data collected from the test will
inform UAVOS’ developments of future medium altitude long endurance unmanned aircraft
capabilities,” said Aliaksei Stratsilatau, CEO at UAVOS.
