Korean KUS-FS hollow long endurance drone. Recently, South Korea held its first large-scale military parade in 10 years. During this period, among the first drone squadrons to appear, several new types of drones were unveiled, showcasing the development achievements of South Korea's unmanned aerial combat capabilities in recent years. The development speed of South Korean military drones is relatively slow. In the early 1990s, the South Korean Ministry of Defense formulated a "three step" strategy for the development of unmanned aerial vehicles, which included developing small tactical unmanned reconnaissance aircraft, then developing medium long endurance drones, and finally developing strategic reconnaissance drones. The "three step" strategy is gradual and emphasizes technological accumulation, with the ultimate goal of building a complete drone strike system by around 2020. In October 2002, South Korea proposed an overall development plan for unmanned aerial vehicles (UAVs) based on the "three step" strategy, with tilt wing reconnaissance drones, hollow long endurance drones, and stealth drones as the main development models. South Korea adopts a cooperative development approach between research institutions and military enterprises, first conducting technical pre research and obtaining support from military departments before conducting full-scale prototype development. In addition, South Korea is vigorously developing the civilian drone industry and promoting private companies to develop products that meet military standards. At the same time, South Korea actively purchases advanced drones from abroad and strengthens technical cooperation. In March 2021, South Korean Aerospace Industry Corporation signed an agreement with Israel's Elbit Systems Corporation to cooperate in unmanned aerial intelligence, surveillance, observation and reconnaissance fields. On February 28, 2023, the South Korean government of Yoon Seon hyeon released the Basic Plan for National Defense Reform 4.0, proposing to attach importance to the research and application of new technologies such as artificial intelligence, and accelerate the development of a manned/unmanned hybrid combat system based on artificial intelligence. Under the guidance of National Defense Reform 4.0, South Korea established the unmanned aerial vehicle combat command on September 1, 2023. This command is directly under the South Korean Ministry of Defense and is the first joint combat command of the South Korean army. It is responsible for large-scale retaliatory combat support operations in the South Korean version of the "Three Axis System" and has a very important position. At present, the South Korean frontline forces are generally equipped with small tactical reconnaissance drones such as RemoveEye-002 and RemoveEye-006. Both types of drones made their debut at the military parade, using reinforced plastic and carbon fiber manufacturing, electric propulsion, handheld projection, and abdominal landing methods. They have a maximum speed of 75 kilometers per hour and a combat radius of 75 kilometers, providing the Korean army with platoon level reconnaissance capabilities. In addition, Han Jun is also equipped with an Israeli Rotem L suicide drone. This small quadcopter drone weighs only 5.8 kilograms and can be carried by individual soldiers. It can be used for reconnaissance missions as well as suicide attack missions. At the parade, a small reconnaissance drone named RQ-102 was also exhibited. According to reports, the aircraft has a maximum speed of 200 kilometers per hour and a cruising speed of 130 kilometers per hour, using ejection takeoff and automatic recovery methods. Another KUS-7 small drone, also used for reconnaissance missions. In addition, Han Jun was also equipped with RQ-101 drones. The aircraft has a cruising speed of 150 kilometers per hour, a ceiling of 6000 meters, and a range of 6 hours. It adopts ejection takeoff, landing gear taxiing, or parachute landing back
