Kanwa turning an outdated news to something new...

The first batch of J-11B entered the service with PLAAF 1st Division (S/N 10x2x) in late 2007. However the initial batch of J-11Bs powered by the indigenous WS-10 turbofans were quickly grounded due to the poor quality of the engine. Subsequent batches are forced to be powered by Russian AL-31F turbofans until WS-10's reliability problem is solved. The latest image (December 2009) suggested that the engine quality problem was partially solved and the aircraft (02 batch?) has started to fly with WS-10s installed. The latest rumor claimed that PLAN is starting to receive land-based J-11Bs (as J-11BH?) in spring 2010, which wear a light gray camouflage.

Update on the J-11B Project.
Recently surfaced photos indicate that the WS-10A turbofan engine is now operational with the J-11B heavy fighter.
According to the PLAAF 60th Anniversary Warplane Show, the J-11B conducted its maiden flight on December 2003 and entered service with the 1st PLAAF Fighter Division on December 2007. The initial batch of the J-11B was powered by the imported Russian AL-31F turbofans engine instead of the delayed WS-10A.

In addition to the engine, the J-11B differs from the J-11A in other areas; it features a new quadruple-redundant digital fly-by-wire flight system with mechanical backup, a new multimode pulse Doppler radar for indigenous armaments against land/sea/air targets, and a new cost of composite material to reduce weight. It's redesigned cockpit is equipped with a new set of instruments ranging from a holographic HUD, four LCD MDFs, to a new missile warning system.
