At the moment we are able to see military aircraft NOT belonging to Russia in the conflict zone. well most of them, as I'm sure some are incognito.

Is it that all Russian airframes are operating with jammers, or some other blocking tech ? There are several surveillance airframes going up and down the western border of Ukraine and Belarus, so they will know what's what in terms of the sky.

Several possible reasons, some or all of which may apply:

1) Russian aircraft flying combat missions don't feel the need to switch their transponders on

2) FR24 feeders in Ukraine have more pressing things on their minds at present

3) FR24 is voluntarily suppressing some information

Don't forget that, despite the name, FlightRadar24 isn't radar at all, it's essentially datacomms and relies on the participation of the targets.

All salient points, though I was referring to trackers, rather than just FR24. Regarding the Russian aircraft wouldn't they require some form of transponder, even if just a secure signal to show command where the chess pieces were, so to speak ?

Russian aircraft will almost certainly have IFF so they can avoid shooting each other down.

Whether they send anything on the frequency that FR24 feeders' receivers are hard-tuned to is another question, and even if they do, they certainly won't be broadcasting their position for the world to see.
