I don't thing having this type of task force is realistic. If anyone is worth helping they need to provide a base for Russia.
The US built a nice base in Cam Rahn Bay in Vietnam... but then their side lost and the Soviet Navy went in to use it... much like if Russia had done nothing in the Crimea then HATO and the US would probably have moved their ships in to Sevastopol...
The problem is that such bases are much more expensive than any carrier group and subject to change of ownership either from war or simply a coup.
And even then having a friendly port you can operate from means nothing if you only have corvettes to operate there.... who is going to build you a port for Frigates and Corvettes?
The US has a massive network of bases to sustain operations, and that is really only because no one of significance has tried to oppose them.
They do but that is part of their world police complex... and economically it is killing them.
Interference with Russian commercial business is more effetively done by sanctions, if they actually start to interdict Russian ships, Russia can do a lot of its own interdiction.
The situation in Georgia told the Russians that they cannot rely on the international community to help... even when they are clearly right... and also the support the US provided to Georgia... a country they took as cannon fodder to Afghanistan and Iraq... was pathetic and useless because their navy could not reach... now they could have sent army forces or air power via Turkey which is right next door... but it seems their best option was still their navy because it would be a more complete and useful force... the Georgian conflict left the US in the same boat so to speak as the Russians found themselves in Serbia/Kosovo.... just words and not force.
It would be cheaper and more useful (more mobile and independent) to build destroyers and cruisers and aircraft carriers... than to try to pick some countries and either build new ports for them or ask them to upgrade ports for you... with the promise of future protection.
You don't become a world power and then build a navy.... it happens the other way around.
You cannot mount sustained ops without bases and you cannot have bases without a navy.
Of course you can mount sustained ops without bases... it is just easier if you do have local support... They have support tankers as shown in the Auxiliary Ships thread that carry fuel and food and fresh water to maintain other ships on location for long periods... such vessels could also support oil and gas tanker operations delivering energy around the world too.
This is why Russia now has overseas naval bases in Syria, Vietnam and now Sudan (I think this one is quite new) I suspect they will have one in either Cuba or Venezulela again
Russian troops in Syria still have a job to do so having air and naval bases makes sense. They have a new base in Sudan but I don't know of any Russian base in Vietnam that is currently being used, nor in Venezuela or Cuba at the moment.
Of course they don't need Actual bases... just good relations with countries would be good enough where they can go in to port and receive fuel and water and food supplies and maybe fly in a replacement crew perhaps...
But if you look at the economic ramifications of being in Russias orbit, the price paid by Cuba is really appalling.
The price paid by Cuba was for saying no to the US... not for saying yes to the Soviet Union... Iran is not best friends with Russia or the Soviet Union and it gets the same treatment essentially... as does North Korea...
The price Cuba pays and is still paying reflects more on the US than anyone else.
I wonder if it will be longer or if they will replace some of the SAMs.
Maybe they have shifted a few other things around to fit more in essentially the same space.
