At this times---any weapons procurement by KSA or GCC must have a different approach from the past---.
Let us assume---to form a complete battle force---they need subs and ships and air force and ground force---.
But for any of these forces to work properly---they will have to learn to build the machine as well.
And that is the most important part of all---until and unless these nations do not start to be a part of building and manufacturing of these machines---their level of performance in battle will never go above satisfactory---means that they will never excel OVERALL.
Because there is no vested interest in it---there is no sweat and blood involved in it---there is no LOVE involved in it---there is no romance build up---there is no true claim of ownership involved here but only the transfer of funds and exchange of equipment from the manufacturer to the end user---if it works---it works---if it does not blame it on the manufacturer.
Submarines are a totally different animals---to tame the beast---you will have to learn about the innards of the beast---and to do that---you will have to build it as well.
@Khafee --- I like your thinking---KSA and GCC need subs---.
