In December 2008, rumors were rife of the J-10's latest incarnation, the J-10B to have taken off for the first time. Now in April 2009, we see for the initial leak of images for this plane. The J-10B appears as the next iteration of China's vaunted 4th Generation fighter and looks to take the J-10 to the 4.5 Generation level. The differences that have been identified from the earlier J-10 include a DSI intake, similar to the one on the FC-1/JF-17. The nose is now oval, more similar to an F-16's and is slightly canted downwards. An IRST similar to the J-11Bs also feature on top of the nose. Slanted radome paint along with some of the other features suggest an AESA radar.The J-10B incorporates a new small ECM housing on the vertical stabilizer and this stabilizer also appears to be longer and ending in a "shark-fin". The ECM housing is similar to the housing on the JF-17. The two ventral fins are also extended further and are larger irrespective of the shark-fin. The aerodynamic refinements of the longer vertical stabilizer and the ventral fins appear to be a result of the DSI intakes which create greater lateral forces on the aircraft. The wide angle HUD featured on the J-11Bs seem to have also appeared on the J-10B. While it cannot be confirmed, it appears that the cockpit itself has been redesigned extensively. Other than the new ECM housing on the vertical stabilizer, new MAWs appear on the tail bump. Just below these, curious breaks appear on the fuselage that some observers are referring to as possible formation lights "slime lights", but expert opinion from a Lockheed Martin source suggest that they are FLIR sensors. A redesigned satellite communication unit appears right behind the cockpit. A retractable refueling probe is likely, given the development of the J-10 thus far, and is possibly located on the port side, not visible in the latest photographs. The photographs also suggest new under-wing pylons. These appear to be strengthened for a variety of possible uses, ranging from larger drop tanks to ASMs. The engine is likely to be either a redesigned WS-10A (B?) or possibly the WS-15, a new generation engine currently in advanced development. This would not only have higher thrust than the AL-31s, but also feature TVCs, giving the J-10Bs vaunted agility an even greater boost. The actual engine on the aircraft presently on the released pictures, is the AL-31. Like the J-10S, a J-10BS is also eventually likely. This would be an advanced trainer with the 360 degree view similar to the J-10S. EW/Wild Weasel variants could also eventually be possible.
