Seal Beach Weapons Depot....missle cruisers come in and deposit their nuclear weapons prior to going to port.
Long Beach Shipyard has been gone a long time now.

I am down there all the time and there is nearly always a big ship there.
I seriously doubt that our missile crusiers are carrying nukes.
They would do an offload after deployment for the SM2's & Tomahawks,
but not for a single port visit.
