Since the formal success of the Chengdu J-20 after the launch of the performance test, the Chinese military forum recently exposed the Chengdu J-20 “2012” prototype to hang four sub-tank test flight, indicating that the model flight test task has entered end. Allegedly, the fuel tank can make the Chengdu J-20 range greatly increased to 6500 km, enough to fly from the northeastern China breath to Alaska, verify its external load capacity.
From the outflow of the photos clearly visible, Chengdu J-20 wing has four plug-in points, in addition to plug-in fuel tank, but also can be linked to PL-10 / PL-15 air-to-air missiles. “The observer network” analysis, the number of sub-tank mount test flight, there may be in the test Chengdu J-20 non-refueling transition range, that is, in China by loading fuel tank to increase the voyage of the emergency transfer capacity.

In fact, due to the five generations of machines to emphasize stealth and maneuverability, plug-in weapons system for the fighter’s supersonic line patrol and stealth ability, no doubt a huge burden. To solve this difficult problem, the world’s five generations of machines used mostly built-in bomb bay, but does not mean that the five generations of machines in any case do not need to use plug-in system. When carrying out cross-regional combat missions, the fuel tank can not meet the needs of the patrol voyage, this time the fuel tank mount, will be in the temporary transition to expand its voyage advantage.
In addition, the five generations of machines play the important node of the battlefield “hunting” task, in the face of air defense system is damaged or weak air defense system area, this time for the stealth capability requirements are not strict, plug-in all kinds of missile capabilities can play Great destructive power.
Familiar with the military estimates that the addition of fuel tank can make Chengdu J-20 range increased to 6500 km, enough to fly from the northeast of China to Alaska; more than four hanging under the PL-15 or PL-21 missile, also Can effectively hunt enemy early warning aircraft and tanker. And the hunting of such “high value low mobility” air combat auxiliary mission objectives, itself is also an important part of the design requirements of the five generations of machines.
