The latest batch of China's J-15 aircraft carrier-based fighter jet is getting fresh, green priming paint instead of the previous yellow one. Reports speculate it is a new anti-corrosion material that can enhance the aircraft's capabilities.

The colour change in the priming paint likely indicates that it features a new type of anti-corrosion material, Weihutang, a column on military affairs affiliated with China Central Television, reported on Tuesday.

This will contribute to an increase in the J-15's usage, lower maintenance costs and greater lifespan, the report said.
