And I agree. I really don't know where that someone got an idea that PH is diving in into it just like that. I think I did not fail to mention that what they are thinking is around 2020 - about the time frame you gave.Seriously, the Philippines is not ready for any type of submarines now or 2 to 3 years from now. I think (IMHO) they would probably be ready to dive-in into this new class of naval armament in 6 to 8 years? Just like somebody stated, there is so much preparation for submarine operations. The Phippine navy will be lucky if their sailors are proficient to operate the ships that they're planning to acquire now in the next 2 or 3 years. It takes time to be proficient in operating more modern ships. I think it is taking at least 6 months for Philippine sailors to learn how to operate those Hamiltons and those ships are at least 40+ years old.
Really, I do not know where people got the idea that it will not take time for training, preparations and the necessary infrastructures. Just the delivery time will take years if they choose to buy new but if they intend to get 2nd-hands or they are targetting a particular 2nd-hand sub from another country it's also wise to tell that particular country that they are interested as to have those inspected and if deemed feasible and not a waste of money to have those units reserved and stored for them before it gets scrapped or converted to trainer subs.
Also, if those 2nd-hand subs still contains classified technology then the OEM can get rid those technology before they transfer them into another country. That is just common sense. That is if they still classify those as classified technology rather than obsolete. This is as much as the same as export variants of German and Russian subs does not contain classified technology in them that Germany and Russians uses. I though this was already understood but I guess I was wrong.
