中国空军训练照片展示Y-20B加油运输型
Chinese air force reveals Y-20B tanker-transport variant in official training image
中国军方公布的训练照片显示，Y-20B重型运输机装有机翼加油吊舱，呈现加油与运输兼用构型。照片中飞机后舱门开启，地面车辆正在装载训练；中国媒体将其确认为Y-20B。军事评论员称，该机内部燃油足以为中型或重型战斗机加油，无需在货舱加装油箱，但照片仅显示其构型，相关报道认为这可能意味着该型已服役。
China’s military has published what appears to be the first official photograph of a Y-20B heavy transport aircraft in PLA Air Force livery fitted with aerial refuelling pods, suggesting that the multi-role tanker-transport (MRTT) configuration has entered service.
An image published by the PLA Daily newspaper on October 14 shows the four-engine aircraft painted in standard military grey, with refuelling pods beneath its wings and its rear cargo ramp open as a truck carrying equipment is behind it.
The caption said an unnamed air force unit was conducting loading training in mid-autumn. While the PLA Daily did not identify the aircraft, state broadcaster China Media Group and China Military Bugle, a PLA News Media Centre social media account, both identified it as a Y-20B on Monday.

What do we know about China’s two next-generation aircraft?
In the same October 19 report by China Media Group, military commentator Fu Qianshao said the Y-20B carried enough internal fuel to refuel medium or heavy fighters without additional tanks in the cargo compartment, allowing it to retain space for personnel or equipment.
A Chinese military commentator had already concluded in an October 13 opinion piece that the MRTT version had formally entered service, citing photographs showing the aircraft in PLA Air Force livery with refuelling pods fitted.
