I’m sure that ship will always have at least 1 of our nuclear attack subs watching her 24x7 silently.
The sub that was supposed to be doing that was in port for mandatory diversity training and the installation of gender neutral heads (bathrooms).
Also, if you hadn’t noticed, Obama winnowed down our fleet - including the replacements for the Los Angeles class boats, the Virigina-class. Which are actually deliberately degraded from the original 688 follow on, the Seawolf class. Which we only built three of before we decided we didn’t need an awesome underwater killer and went with the cheaper Virginia buses with less capability.
