BRIN Successfully Tests New LSU-02 VTOL and Alap-Alap Winged Drone Systems in Bogor.

The National Research and Innovation Agency (BRIN) has completed a successful series of winged drone flight tests in Bogor, Indonesia. The tests focused on validating core systems for four unmanned aerial vehicles (UAVs). This effort is part of a broader strategy to advance Indonesia domestic drone technology. The goal is to establish the country as a producer, not just a consumer, of advanced UAVs.

Flight Test Success

BRIN's Research Center for Aviation Technology conducted the tests at Lanud Rumpin between December 17 and 19, 2025. A key focus was the LSU-02 VTOL Alap-Alap aircraft, designed for vertical takeoff and landing. This feature allows the drone to operate without a long runway. The LSU-02 VTOL flew for eight minutes at 300 feet and a speed of 53 knots. Researchers confirmed the aircraft’s flying performance and VTOL system functioned as expected. The drone is primarily intended for territorial surveillance and area mapping missions.

Another fully developed BRIN aircraft, the Alap-Alap, underwent flight testing to optimize its autopilot systems. It reached an altitude of 800 feet and a speed of 50 knots during its 30-minute flight. Test results confirmed the autopilot system was functioning properly.

Core Technology Development

Young Expert Researcher Danartomo Kusumoaji confirmed that BRIN researchers fully designed the LSU-02 VTOL and Alap-Alap. This includes the crucial internal Flight Control Computer (FCC) technology. The development of indigenous FCC is vital for technological independence.

Two other models, Skywalker and Krishna, were also tested. These drones used existing airframes modified by BRIN researchers. The Krishna model, based on a Cessna aircraft design, focused on evaluating its telemetry system. This system is critical for sending real-time flight data telemetry to ground stations. The Skywalker drone tests were used to identify aerodynamic parameters and flight stability. Data from these flights will help refine future designs and improve overall unmanned aerial vehicles performance.

Advancing Domestic UAV Technology

The successful trials underscore Indonesia's commitment to building a robust national drone ecosystem. The country has a long-standing interest in UAVs for monitoring its vast borders and maritime zones.

• Opportunity: The research directly supports civilian applications like mapping, agriculture, and logistics.
• Challenge: The domestic market still often favors foreign-made drones.
• Strategic Impact: BRIN's work, supported by government initiatives like the Domestic Component Level (TKDN) program, aims to strengthen local components.

Achieving full autonomy in drone technology is a significant step for national resilience. The data gathered will be essential for future designs that meet both local and international standards set by bodies like the FAA and ICAO.
