In one answer to both.... given that they needed to send a tug along just in case it would break down (again!), it can't have been that cost effective, nor impressive...
When Russian state television is reporting live from the Kuznetsov that they have commenced bombing Syria and only shows Flankers carrying only A-A missiles, you understand it's only for local Russian PR.
All the Su-33 used in Syria are equipped with Gefest. The same bomb aiming as Su-24M used in Syria.
The others Su-33 are planned to rebuild for Gefest.
The state television reports are certainly not from bomb aiming missions, only just for show.
