LAPAN LSU-03
Indonesian tactical UAV with extended range and payload capacity.
The LAPAN LSU-03 (LAPAN Surveillance UAV-03) is a tactical unmanned aerial vehicle built by Indonesia’s National Institute of Aeronautics and Space (LAPAN). It is an upgraded version of the LAPAN LSU-02, with a maximum range of 600 kilometers—roughly 133 percent of the LSU-02’s 450 kilometers—and a much larger payload capacity.
Development began after the LSU-02 proved successful. The first flight of a pre-production model, which had a theoretical range of 350 kilometers and could carry 10 kilograms of payload, took place on 25 January 2014 to test stability. This model cruises at 100 kph and reaches a top speed of 150 kph, powered by a 100cc two-cylinder piston engine driving a 24x12 pusher propeller, using 7 liters of Pertamax Plus fuel and a Lippo battery.
Between 2015 and 2016, LAPAN created a higher-performance variant called the LSU-03 NG (Next Generation). While the earlier version offered 350 kilometers of range and 10 kilograms of payload, the NG version achieves 600 kilometers and 24 kilograms of payload, improvements attributed to weight reduction. The NG model uses Glass Fiber Reinforced Polymer (GFRP) with plywood supports in a semi-monocoque structure, the same material technology found on the LAPAN LSU-05 drone.
The LSU-03’s payload includes a FLIR camera, a Lippo battery, and other electronics. It can be controlled by radio or autonomously via a mission planner from a ground control station. It also features anti-jamming technology: if the signal is jammed, the UAV automatically returns to its takeoff point.
In November 2015, the LSU-03 flew a photographic mission from Pameungpeuk to Pelabuhan Ratu and back, setting a new MURI record for the longest UAV range at 340 kilometers in 3 hours and 39 minutes. The previous record, held by the LSU-02, was 200 kilometers in 2 hours and 37 minutes.

Lore & Background
Development of the LSU-03 began after the success of the LSU-02. The first flight took place on 25 January 2014 to test the stability of the pre-production model, which had a theoretical range of 350 km and a 10 kg payload. Technically, the LSU-03 uses a 2-cylinder 100cc piston engine, a 24x12 pusher propeller, 7 litres of Pertamax Plus fuel, and a Lippo battery. It has a cruising speed of 100 kph and a maximum speed of 150 kph.
Between 2015 and 2016, LAPAN developed a higher-performance version called the LSU-03 NG (Next Generation). This version achieved a 600 km range and a 24 kg payload, improvements attributed to weight reduction. The NG version adopted Glass Fiber Reinforced Polymer (GFRP) material with plywood as support in a semi-monocoque concept, similar to the material technology used on the LSU-05 drone.
The payload of the LSU-03 consists of a FLIR camera, Lippo battery, and other electronics. It can be controlled via radio or autonomously using a mission planner from a Ground Control Station (GCS). It has anti-jamming technology installed; if jammed, it automatically returns to its former take-off area.
Reader's Guide
The LAPAN LSU-03 represents a significant step in Indonesia's indigenous UAV development, building directly on the capabilities of the LSU-02. Its operational history includes a notable mission in November 2015, when an LSU-03 flew from Pameungpeuk to Pelabuhan Ratu and back, covering 340 km in 3 hours and 39 minutes. This flight set a new MURI record for the longest UAV range, surpassing the previous record held by the LSU-02 (200 km in 2 hours 37 minutes). The development of the LSU-03 NG version further extended the platform's range to 600 km and payload to 24 kg, demonstrating LAPAN's iterative improvement approach. The use of GFRP materials and semi-monocoque construction, shared with the LSU-05, indicates a progression in Indonesian UAV manufacturing techniques. The inclusion of anti-jamming technology and autonomous return capability enhances operational reliability. As a tactical UAV, the LSU-03 serves roles in surveillance and reconnaissance, with its FLIR camera payload suited for imaging missions. Its record-setting flight and subsequent upgrades underscore its role as a milestone in Indonesian aerospace engineering.
