Its a Pearl Harbor invite.
A Chinese container ship could be fitted out with Yakhont or other module bank launch cruise missiles.
You could put 50 -100 and have them look like normal shipping containers.
Plodding allong up the coast on a scheduled commerce run to New York.
In minutes 50-100 nuclear and TNT/Thermitic charge warheads skim or arc in on Norfolk.
Its easy to say it would never happen.
Yet such coup's have occured in war.
Said container ship on a certain suicide mission could also seed the ocean with mines and the Norfolk base entrance.
Its left to the imagination of the attacker.
