[Yorktown_Class]

I love this movie and have seen it several times,when the captain of the Haines says he could be pulled into a fight with a German raider,is he reffering to a Hansa Class ship?
He says that it could out gun and out run his Buckley Class DD,I know it is just a movie,but was just curious if this is true and is he reffering to a Hansa or something else...thanks
