空中加油操控台/Air Refueling Control Console
my $.02 because everyone else has, The PLAAF needs Tankers. We all know that.
There are two concepts for this Flying boom and Probe and Drogue.
- Flying boom is rarer, it has a major advantages. You can fuel up faster because of the pipe, but only a hand full of users use it. Thus far if the PRC invested in it, I can only think for export. As none of the PLA aircraft have a flying boom receptacle. US made Fighters that started in the USAF like the F15 and F16 demand Booms same for Some older F4 and A Flying boom Can be modified to tank Aircraft with a Probe and Drogue system. Downside it's heavy, demands an Operator and you can only mount one.
- Probe and Drogue is far more common and already the standard of PRC. It's 1 easier to build, you can tank multiple aircraft meaning if you build a large tanker you can get more use from that tanker per flight than a flying boom. it's more universal in that it allows tanking of not just fighters and bomber but also Helicopters. Again meaning you can get more use from the tanker as you have a expanded envelope. Down side is not as easy to tank up with because it's subject to turbulence and it has a slower refuel speed. There is some risk of fuel or the Drogue damaging the receiving aircraft. The Russians and Chinese as well as all the Tanker operators of the World already have provisions for Probe and Drogue. Even flying boom tankers can be fitted with an adapter to fuel Probe an Drogue aircraft however Probe and Drogue tankers can not.
Now If it is a study for export that could make some sense a few F16 and others who use older USAF type F4 have shall we say fallen from US favor. As I stated above A Flying boom Tanker can be modified to refuel a Aircraft using Probe and Drogue via an adapter.
So from an Export perspective if one of the PRC builders was looking to offer a Tanker program for both the PLA and possible Export to it's allied states a Flying boom like system would be a good option as you could mount one. If the End customer says They don't use it. Then you can modify the system to a Probe and Drogue.
So if you are building it off say a Comac 919 ( Hypothetical here) you can then have 3 refueling points One center line with a flying boom system installed but able to be modified for Probe and Drogue and 2 Probe and Drogue systems on the wings.
meaning that a 3 ship formation of fighters could be tanked at the same time. And this is a real configuration used on some MRTT like the A310, A330, KC46 ( troubled though it is)
Of course it could just be that they thought it looked cool. But I think my little Theory works well as you see the a Flying boom but the picture to the right ( our perspective) is clearly a Probe and Drogue receiving aircraft.
