Walker class

The Walker class was a type of Federation starship in service during the mid-23rd century.
==History==
By 2249, the Walker class was considered "old" compared to other ships in the fleet. ()

==Technical data==
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.
This ship class was capable of atmospheric flight by means of thrusters scattered over its ventral hull. The ship's armament included phase cannons, phasers, and photon torpedoes. The ship was equipped with internal and external plasmatic filters.
The ship's medical facilities featured an antiproton chamber. ()
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 did not change significantly by the development of the more advanced ships, 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 brig was located on deck nine. ()

===Background information===
The Walker-class was named for NASA test pilot . (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 .
The Walker-class, represented by the , was designed by John Eaves in conjunction with 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 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. (Star Trek: Discovery The Official Starships Collection, issue 1, pp. 9-10)
The Walker-class was meant to incorporate elements from from and the from , 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) Eaves also produced a four-nacelled concept design for this class of vessel, in mid-, which later played a part in inspiring the design of the . (Star Trek: Discovery Designing Starships, p. 74)
According to Eaves, "the only real note I had was that the bridge was going to be on the bottom, plus we knew it was going to be an older ship." During the process of designing the Shenzhou, many of the variety of designs Eaves conceptualized would be later used for other Starfleet ships. In finalizing the design, "I wanted something non-traditional to tie it all together. I thought about something that Tony Moore at Edwards Air Force Base told me about, which was a 'blended body' aircraft, where everything smoothly transitions into itself, so the hull blends into the winds and so forth [….] So my hull blended with the saucer." The final product resulted with "a body that arched across the top of the saucer with the bridge on the bottom, so it had all the necessary elements, but in a new layout." (Star Trek: The Art of John Eaves, pp. 188-191)
===Apocrypha===
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). 
The Walker class issue of the Star Trek: Discovery The Official Starships Collection further claims a length of 423.37 meters, as does a size chart in The Art of Star Trek: Discovery where the figure is 1389 feet 0 inches. This would make it about 1.5 times as long as a TOS starship (whose size was increased by a factor of 1.5 itself for Star Trek: Discovery).
The Walker class is a playable ship in Star Trek Online, classified as a "light exploration cruiser". The game also introduces two design variants, the Georgiou class (based on the ) and the Shenzhou class (a 25th century update).
