In tune with other leading military powers of the world, China has delved into the realm of the Unmanned Combat Air Vehicle (UCAV), a remotely-piloted aircraft with weapons delivery capability, through its unveiling of the Hongdu Lijian ("Sharp Sword"). The aircraft represents China's first official foray into a jet-powered, stealth-minded Unmanned Aerial Vehicle (UAV) and is believed to serve the role of technology demonstrator for a possible future combat system.

The design was photographed during a taxiing run in May of 2013, officially marking its appearance in the Chinese aircraft inventory. The "Sharp Sword" is one of several all-wing designs tracing its roots to the AVIC 601-S UAV project. This includes "Wind Blade", "Cloud Bow", and "Warrior Eagle".

Externally, the vehicle takes on the form of the competing (and in-development) Northrop Grumman X-47B complete with frontal air intake and tailless profile.

The Lijian exited a period of development that spanned some three years and involved both Hongdu and Shenyang aircraft makers. The end-result was a flying wing with a turbofan buried within the bulbous fuselage. The overhead profile of the aircraft is reminiscent of the Northrop Grumman B-2 "Spirit" stealth bomber and lacks any vertical fins of any kind. It is presumed that there lies an internal weapons bay for munitions. The tricycle undercarriage is fully-retractable and consists of two main single-wheeled legs and a nose leg.

As it stands, the Lijian is thought to be powered by the same Shenyang WP7 series engine as featured on the J-7 fighter series. Estimated specifications include an operational range out to 80 miles with a payload-carrying capability not exceeding 4,000lb. The structure includes a wingspan of some 46 feet.
