The Dauntless.
See it has subtext. Exploration and discovery require courage, the unknown is scary. To be Dauntless is to be unafraid of any challenge no matter how hard, it would represent our ability "To strive, to seek, to find, and not to yield". The second one could be called the Ulysses. They need to represent our ability to be more than ourselves and to push every frontier. So I vote Dauntless and Ulysses. Imperator, Oberon and Furious Abyss are also pretty damn cool but less meaningful.
