You can range the whole pacific with DE boats the issue is how long they can stay in their patrol area, dunno the accuracy but there was someone saying a DE could spend 7 days on station in south china sea based out of perth while nuclear could spend 70 days
The whole china sea in reality is sorta enclosed theres only a few ways in and out, so much of shipping has to through enclosed straights, the video linked below he looks at it the shipping routes and just look at suff going through the big straits like malacca
