The LAPAN LSU-03 (LAPAN Surveillance UAV-03) is an unmanned aerial vehicle (UAV) developed by the Lembaga Penelitian dan Penerbangan Nasional (LAPAN) of Indonesia. It is a further development of LAPAN LSU-02, and both is classified as tactical UAV. While it is basically a further development of LSU-02, LSU-03 can achieve maximum range about 133% of its predecessor (600 km compared to 450 km of LSU-02) and significantly more payload.

Design and development

The LSU-03 development started after the success of LSU-02. First flight take place in 25 January 2014 to test the stability of pre-production model. This pre-production model has a theoretical range of 350 km and 10 kg payload. Technically LSU-03 has a cruising speed of 100 km/h and maximum speed of 150 km/h. It uses a 2-cylinder 100cc piston engine, 24x12 pusher propeller, 7 litre Pertamax Plus fuel and lippo battery.^[1]

In period 2015-2016, LAPAN developed a higher performance LSU-03, dubbed LSU-03 NG (Next Generation). While the former version has a 350 km and 10 kg payload, this version has a 600 km range and 24 kg payload. This improvement is believed due to reducement of weight. The new version adopted GFRP material (Glass Fiber Reinforced Polymer) with plywood as support in semi monocoque concept. Similar material technology has been used on LSU-05 drone.

The payload of LSU-03 consist of FLIR camera, Lippo battery and other electronics. It can be controlled using radio or autonomously using mission planner from GCS. It has an anti jamming technology installed, even if it is jammed, it will automatically return to its former take-off area.^[2]

Operational history

In November 2015, LSU-03 took flight for a photographing mission from Pameungpeuk, Cilacap, to Pelabuhan Ratu and return to Pameungpeuk. The mission broke new MURI record for longest UAV range, which is 340 km in 3 hour and 39 minutes. The previous record holder was LSU-02, that flew 200 km in 2 hour 37 minutes.^[3]
