Blurry images of two seemingly new Chinese military aircraft with stealthy characteristics appeared online on Friday, with defence experts saying they were clearly advanced designs, but there was not enough detail for definitive conclusions.

China has made it a national priority to develop military jet engines for its fighter jets, bombers, transports, and UAVs.

The new Chinese aircraft are not the first modern tailless designs. The Northrop Grumman B-2 and B-21 stealth bombers are both flying wings, and several uncrewed aircraft, such as the Lockheed Martin RQ-170 and China's CH-7, lack tails.
