Physical arrangement Edit
The design of the Walker-class consisted of a saucer section with an integrated, laterally-positioned navigational deflector, a compact secondary hull, and two nacelles attached by pylons extending beneath the ship's superstructure.
The Walker-class had at least fifteen decks and two shuttlebays. It carried a compliment of shuttlecraft and worker bees, as well as escape pods which could be launched from breakaway panels lining the top of the saucer section.
Atypically for a Starfleet vessel, the bridge was located on the underside of the saucer, on deck seven, and had an adjacent captain's ready room. The internal arrangement of the Walker-class was not dissimilar to that of the more advanced Crossfield-class, with nearly identical corridors and crew quarters. The Walker-class possessed transporter systems similar to that of the Crossfield-class; however, it was equipped with lateral vector transporters, a design deemed obsolete by the late 2240s.

The Walker-class was named for NASA test pilot Joe Walker. (; Star Trek: Discovery The Official Starships Collection, issue 1, p. 10) A photo of Walker standing next to Little Joe, a Bell X-1E, was used as set decoration in the Shipyard Bar, a location visited in the film Star Trek.
The Walker-class, represented by the USS Shenzhou, was designed by John Eaves in conjunction with Star Trek: Discovery production designer Todd Cherniawsky, under guidance from co-creator Bryan Fuller who requested that the ships have a lower profile than that of the original USS Enterprise and possess angular nacelles. In order to rationalize this divergent design ethic, Eaves and Cherniawsky speculated that Starfleet of this era might have deviated from earlier, Vulcan-inspired designs, or that the Shenzhou and Discovery originated from a different production base than the Enterprise.

The Walker-class was meant to incorporate elements from Enterprise NX-01 from Star Trek: Enterprise and the USS Reliant from Star Trek II: The Wrath of Khan, as well as 1940s aircraft. The distinctive red livery adorning the Shenzhou was added after the design was finalized and the Atzec-patterning deemed too subtle. Eaves also created a rendering of the ship with turquoise livery, but this was not utilized in the final design. (Star Trek: Discovery The Official Starships Collection, issue 1, pp. 10-13)
According to technical data prepared for the San Diego Comic Con in 2018, the ISS Shenzhou had 13 decks, a crew complement of 150, a maximum warp of 6, and two impulse engines (approximate warp factor 0.3).
