Emissary-class shuttles were hyperdrive-equipped shuttles used by the Galactic Republic. They were referred to as serviceable, but far from luxurious, like the Theta-class shuttle.
Emissary-class shuttles were known to be in use in the time following the New Sith Wars. The New Dawn, a shuttle owned by Chancellor Tarsus Valorum, was an Emissary-class shuttle.
