They have to run transponders over the US so that commercial aircraft know their position and don’t collide. Once they leave our airspace, (or in special circumstances where the airspace is cleared) they will run without. These are just basically civilian transponders they run to “be polite” - they are also filtered by most flight tracking sites. Some (such as the one pictured) allow one to look at the raw data (and likewise you can run an SDR transponder receiver yourself at home to see what aircraft are over you.)
Sometimes they will bluff the transponder value and say things like, “hey I’m a Cessna going 400 knots” but most of the time they just say who they are.
Fun fact! The transponders don’t work over the oceans anyway, since there’s nobody on the surface to pick them up, you’re basically a ghost once you leave land, (surrounding aircraft can see each other, however) think about that during your next trans-ocean flight. They increasingly have satellite Internet these days to have some form of comms, though.
Nah, that exercise only involves a handful of KC-135s. We’re seeing 30+ KC-46 Pegasus and KC-135 Stratotankers being strategically redeployed. This is something else.
We were also running transponders on tankers even when they were refueling aircraft around Ukraine (albeit in friendly airspace).
The refuelled aircraft (at least some of which were F-35s, if not all, as someone geolocated a picture during the conflict) were not running transponders, though (and in the case of the picture of the F-35, had the radar reflectors removed).
First, they are probably actually participating in this annual training exercise: https://www.europeafrica.army.mil/Defender/
