The Chinese navy intensively exercised its upgraded J-11B fighter jets over the disputed South China Sea following mass delivery of the advanced model, according to state media reports.

More than 10 fighter jets from the People’s Liberation Army’s Southern Theatre Command participated in “round-the-clock” training and battled in four-versus-two and two-versus-two formation, official broadcaster China Central Television (CCTV) reported.

CCTV’s footage of the drill showed a J-11B returning from the exercise and entering its hangar, with the aircraft featuring a grey radar dome, unlike the black sported by the original versions.

The change in colour has sparked speculation about its being a sign of a radar upgrade to a hi-tech active electronically scanned array (AESA) system, according to nationalist tabloid Global Times. The computer-controlled AESA system allows jets to communicate better, as well as detect targets earlier and at longer range.

The J-11B is a significantly modified version of the Soviet-designed Sukhoi Su-27 fighter from state-owned Shenyang Aircraft Corporation (SAC). It remains the most advanced fighter jet operated by the PLA Navy’s land-based aviation force, alongside some Su-30MKK imported from Russia in the 2000s.

The twin-engine multirole J-11B has a range of 1,500km, extendable with additional fuel tanks. It can also carry advanced weapons like the PL-10 short-range combat missile and the PL-15 beyond-visual-range air-to-air missile.
