AIP subs are deadly,real killers.thanks its very informative,
but lets say in the mediterean sea wouldnt countering submarines easier ? with of course specialised modern anti submarine tactics, wouldnt it be very hard to hide there ?
Almost all Mediterranian navies have them,without them your navy is just a ''Navy'' in name.
The problem for your country is experience in submarine warfare,its not just training the crew(2,5 years) but also the interoperability between the various navy systems(frigates,corvettes,air assets,subs etc) which takes at least a decade to master.
