It's not just a matter of money. The mixed task force operation on the deck is one of the most difficult areas of naval operations.
Apart from that, the primary issue is the doctrinal infrastructure. Only those who approach the event on the basis of inventory do not have a deep understanding of the military structures. As far as I know, they are feeding a giant army of advisors who have a very serious US influence in the SA's navy structure. We have a similar picture in the air force. In fact, we know that the shortage of trained personel in the Saudi Arabia has been accompanied by the support of friendly states like Pakistan from time to time.
The second important problem is the logistics flow. The logistic dependence of these systems destroys the entire strategic multiplier effect. If you can support this system yourself and operate it with your own staff, it carries a power factor.
Operational experience and capability
Doctrinal compliance and navy organization
Independent logistics and back services
Powerful economy.
Even if you have dealt with these 4 issues, it should be kept in mind that CSG presence means power transfer capability, and that this is a parallel issue with the power in the global political arena.
