RAF's Protector RG1 Achieves Successful Flight Test Over Lincolnshire

The Royal Air Force (RAF) has successfully conducted a flight test of its latest Remotely Piloted Air System (RPAS), the Protector RG1, over Lincolnshire. This event signifies a pivotal step in the aircraft's evaluation program as it approaches full operational status.

Advancements in RPAS Technology

The Protector RG1 is poised to replace the current Reaper system, introducing significant advancements in intelligence, surveillance, and reconnaissance (ISR) capabilities. Notably, it is the first RPAS certified to operate across all classes of UK airspace, ensuring seamless integration into both military and civilian aviation sectors.

Key Specifications

• Endurance: Capable of operating for over 30 hours, the Protector RG1 offers extended mission durations, enhancing its ISR effectiveness.
• Altitude: The aircraft can reach altitudes up to 40,000 feet, allowing for operations above commercial air traffic and providing a broad surveillance range.
• Dimensions: With a wingspan of 79 feet (24 meters) and a length of 37.5 feet (11.43 meters), the Protector RG1 is designed for optimal aerodynamic performance.
• Engine: Powered by a Honeywell TPE331-10 turboprop engine, it ensures reliable performance across various mission profiles.

Advanced Features

The Protector RG1 is equipped with state-of-the-art technology to enhance its operational capabilities:

• Electro-Optical/Infrared (EO/IR) Sensor: Provides high-definition imagery for detailed reconnaissance.
• Lynx® Multi-Mode Radar: Offers synthetic aperture radar (SAR) imaging and ground moving target indication (GMTI), crucial for identifying and tracking targets.
• Detect and Avoid System (DAAS): Ensures safe operation within civilian airspace by autonomously detecting and avoiding other aircraft.
• All-Weather Capability: Features lightning protection and a de-icing system, allowing operations in diverse weather conditions.

Operational Milestones

The recent flight test was conducted by an all-UK crew from the new RAF ground station at Waddington, led by 56 (Test & Evaluation) Squadron with support from 31 and 54 Squadrons. This marks a significant phase in the aircraft's testing program, focusing on critical integration and operational assessments.

The UK government has committed to acquiring 16 Protector RPAS units for the RAF, bolstering the nation's remotely piloted aviation capabilities. RAF Waddington will serve as the primary operational hub, supporting both training and global deployment operations.

Infrastructure and Training

To support the Protector program, the first Certifiable Ground Control Station (CGCS) and simulator have been installed at RAF Waddington. As of now, four Protector aircraft have arrived in the UK, with additional units undergoing testing in the United States.

RAF engineers from 31 Squadron have been instrumental in assembling and testing the aircraft, ensuring it meets the rigorous standards required for operational deployment.

Future Outlook

As testing progresses, the Protector RG1 is anticipated to provide the RAF with an advanced, long-endurance, high-altitude RPAS. Its ability to operate in complex environments while integrating seamlessly into civilian airspace represents a significant leap in addressing the demands of modern air operations.

The successful flight test over Lincolnshire underscores the collaborative efforts of RAF personnel, defense partners, and industry contractors in delivering this state-of-the-art capability to the UK's defense arsenal.
