History of the Development of the Hongdu JL-10 / L-15 Falcon
The development of the Hongdu JL-10, or L-15 Falcon, can be traced back to the early 2000s when China recognized the need to upgrade its air force training systems. By this time, China’s existing trainer aircraft, such as the JJ-7, based on the outdated MiG-21, were becoming obsolete. These trainers, while sufficient for basic flight instruction, were inadequate for preparing pilots to handle the sophisticated avionics, weapon systems, and flight performance of modern fourth- and fifth-generation fighter jets, such as the J-10 and J-20.
In response to this gap, the Chinese government initiated the development of a new advanced trainer aircraft that could meet the requirements of both its domestic air force and potential international customers. The program was part of China’s broader military modernization efforts, which were aimed at transforming the PLAAF into a world-class air force capable of projecting power beyond its borders.
Hongdu Aviation Industry Corporation, one of China’s leading aerospace manufacturers, was selected to develop the new trainer. Hongdu had prior experience with aircraft design, having worked on the K-8 Karakorum basic trainer, which had been widely exported. For the advanced trainer project, Hongdu sought to create an aircraft that would not only serve as a training platform but also have light combat capabilities, making it versatile for multiple roles.
The development of the JL-10 involved collaboration with foreign partners, particularly the Ukrainian company Ivchenko-Progress, which supplied the AI-222-25 turbofan engines for the initial versions of the aircraft. This engine provided the necessary thrust for high-speed performance while also being economical to operate, a key factor for a trainer aircraft. The use of foreign engines was a stopgap measure as China continued to develop its domestic aerospace industry, particularly the WS-17 engine, which would later equip some variants of the JL-10.
The first prototype of the JL-10 flew in 2006, and subsequent testing phases followed. During the design process, the aircraft incorporated many features commonly found in advanced fighter jets, such as digital fly-by-wire controls, a glass cockpit with multifunctional displays, and a heads-up display (HUD). These systems were intended to mimic the avionics of operational combat aircraft, allowing trainees to familiarize themselves with the technology they would encounter in frontline fighters.
In 2010, the aircraft was officially unveiled, and it quickly gained attention as one of China’s most advanced aviation projects. Its export version, the L-15 Falcon, was marketed to countries in need of a cost-effective yet modern training platform. The JL-10 was designed to operate alongside China’s newer fighter jets, offering seamless transition training for pilots moving from basic trainers to more sophisticated aircraft.
While the aircraft was primarily developed for the PLAAF and the People’s Liberation Army Navy Air Force (PLANAF), it was also marketed internationally. In particular, nations looking to modernize their air forces without the high costs associated with more advanced Western trainers found the L-15 Falcon an attractive option. Countries in Africa, the Middle East, and Southeast Asia expressed interest in the aircraft, drawn by its affordability and advanced features.
