Don't you know how much BIG DADDY USA loves the Philippines? Or perhaps history has not taught you a lesson. We re-took the Philippines back from Japan after the Battle of Leyte Gulf. The some 300,000 Japanese defenders were wiped out. The United States suffered some 60,000 casualties (kia, injured, mia) to liberate the Philippines tho we could have easily bypassed them as per the Island Hopping Doctrine, yet we invaded anyway.
The Philippines remains a very sensitive and close strategic core interest for the United States. Our Mutual Defense Treaty signifies that.
No foreign power will touch the Philippines; anyone who attacks the Philippines will answer to BIG DADDY USA.
9 was built, 8 are active, with 30 being planned.
You were still incorrect by saying that there were 60 active. You did not take into account the Ohio Class subs (18 of them) , the Seawolf Class (3) and the Virginia Class (8 active, 9 built, with 30 to be built overall).
That puts the current SUB FORCE of the US NAVY at around 92 , give or take 1. Not 60 as what you had originally stated.
