All the other ships in the class are named for American cities. According to what I read, Mabus sent a memo down which designated this ship name. So absent any contradictory information, Ray owns this stinker of a decision.
You’re right, Mabus owns this.

Apparently in an attempt to outdo himself, Mabus has also named a Navy cargo ship after Cesar Chavez...
“Cesar Chavez, the Marxist community organizer and farm union leader, who hated the U.S. Navy and capitalism, has been honored with a Lewis and Clark class Naval vessel named the Cesar Chavez.”
