With a 600 mile (960 KM) coastline and the responsibility of an Economic Exclusion Zone of some 92,700 sq. Miles (240,000 sq.km) which is set up to increase by another 21,200 sq. Miles (55,000 sq. km), the PNA has a lot to keep its eyes on. Add a neighbor who is an old time foe looking to establish a blue water navy and the PNA’s ASW platforms are kept busy.
