Naval Base Kitsap
In the other corner of the continental U.S. is Naval Base Kitsap, which was created in 2004 from the merging of two separate naval bases located across the Elliott Bay from Seattle. The largest naval facility in the Navy Region Northwest, Kitsap houses surface ships, submarines, and ballistic missiles.
This no-fly zone is P-51, which might be a little confusing because you’d expect that one to be, well, Area 51.
