The Naval Submarine Base in Bangor, WA - is across the body of water called the Puget Sound on the Olympic peninsula. It feels like it's 2 hours away, but by boat or air, it's less than 20 miles from downtown Seattle.

 Nearly one-quarter of America’s 9,962 nuclear weapons are now assigned  to the Bangor submarine base on Hood Canal, 20 air miles northwest of  downtown Seattle. -source

The stockpile (as of 10 years ago) included:

• 1,100 W76 warheads on Trident IIs
• 850 W76s on Trident I C4s
• 246 W88 on Trident IIs
• 150 W80-0s

Of course, even the largest megaton devices still won't have the range to reach Seattle. I'm not sure what happens though if multiple thousands of warheads go off at once. I myself live just northeast of Seattle, I'd like to think that I'd have time to book it over the mountains if something happened.

The Dolphins

The Navy Marine Mammal Program is part of the Space and Naval Warfare Systems Command (or SPAWAR). The program runs at $14M a year, based mainly out of San Diego, but used for defense for many Naval installations.

Dolphins disable enemy divers by tracking them down and spearing them with needle full of compressed gas. The injected gas expands inside the enemy's body, creating an embolism. This is very fatal. They are also used for detecting and disabling marine mines, and can plant explosives on enemy vessels.

So there you have it, millions of megatons of radioactive death, protected by weaponized sea mammals. Seattle is one of the ultimate cyberpunk cities.
