KRQ-101 Night Intruder 300

As Korea's first Tactical Unmanned Aerial Vehicle, Night Intruder 300 performs its missions of Area Surveillance, Reconnaissance, Target Acquisition, Battle Field Surveillance, and Target Damage Assessment. This UAV is the definitive version of what began life in 1991 as the Daewoo (now KAI) Doyosae, developed with support from the Agency for Defence Development (ADD). South Korea's ADD and Korea Aerospace Industries, Ltd. (KAI) began developing the Night Intruder 300 (initially called Pijo, literally, "flying bird") reconnaissance UAV in 1990, and first flown in 1993.

At the Seoul Air Show in late 1996 Daewoo briefly showed a more fully developed TRPV-1 Doyosae, designated XSR-1. No details were released, but press reports at the time suggested a possible service entry with the South Korean Army in 1998; however, development of the Night Intruder was not completed until August 2000, after more than 100 flight tests.

The Night Intruder 300 is a fixed-wing UAV with a 200 km range and 45 kg (99 lb) payload capability (devoted to infrared sensors and synthetic aperture radar). The Night Intruder 300 made its public debut at Seoul in October 2001, wearing the designation XKRQ-101, and is now in service. A production contract was awarded in 2001, and production continued through 2004. The delivery of five Night Intruder 300 unmanned aerial vehicle (UAV) systems to the Republic of Korea (South Korea - RoK) Army is complete. Deliveries were completed in December 2004. Other indigenous programs have been funded, but the heart of the country's UAV capability as of 2003 lay in purchases of Israel's Harpy.

The nations first strategic UAV (Night Intruder 300) is designed on multipurpose operations to perform missions like wide area surveillance, reconnaissance, target acquisition, battlefield supervision & checking target break-down, and it is also possible to transfer real-time images, especially in unfavorable environments during day and night. It is performing its missions such as aerial surveillance and reconnaissance, target acquisition, battlefield surveillance and bombing guidance.
