What I assume is errection/umbilical arm is retracting.

[edit]
Correction - it was just the errection arm. I can see the smaller umbillical arm still attached

what is this umbilical ?
I guess it's the same than on the Sea launch version ?

The landlaunch ans sealaunch pad are identical. Of course except the ground where they are set up...

ok, thanks.
It's the cryo umbilical for the main stage right ?

No. It's the "mast-cable" (Кабель-мачта) 11U224, built by KBTM. Its two roles are :

- provide electrical connection between rocket (and it's payload) and the ground.

- filling rocket with helium and nitrogen.

Seems like a "hot disconnect system" (I mean it disconnect at lift-off). Am I right ?

If so, why having such a mast for "just" helium an other services gaz ?

Do you know where are the cryogenic and propellant feeding lines then ?

Cheers !
