Taking out a sub with any ordinance that An F15 would have is…unlikely. F15 is an airforce specific craft, thus not a maritime platform.
I don't think you understand how difficult it is to track a sub from the air, let alone hit one with a bomb.
If you knew the location of a rogue sub in Puget sound, why not just send the USS Jimmy Carter to hunt it? That boat is the spoopiest of them all, and it's based put of Bangor subbase, right up the river…
