Its design consisted of a saucer section with a secondary hull positioned below and aft of the saucer. Two warp drive nacelles connected dorsally to the secondary hull with pylons that angled ventrally. The navigational deflector dish was located on the forward face of the secondary hull. A roll-bar mounted near the aft-dorsal of the saucer section resembled a similar structure seen on the Danube-class, and housed photon torpedo launchers. The saucer section also housed a Phaser array strip mounted on top. The secondary hull also houses two quantum torpedo launchers, one on each side of the deflector dish.
The main shuttlebay was at the aft-most section of the secondary hull.
The Luna-class bridge was similar to that of the Galaxy and California class, though the aft section lacked the slight elevation the other two classes' bridge designs had.
The class for the USS Titan wasn't stated on screen, but the trivia question for the "Nepenthe" episode of The Ready Room stated the USS Titan was a Luna-class starship, named after the moon of Saturn.
Pocket Books released a series of novels, called Star Trek: Titan, which are based aboard Riker's ship. The class' pathfinder vessel was the USS Luna (β). All Luna-class (β) ships were named for moons in the Sol system.

The Luna-class was designed by Efrosian engineer Doctor Xin Ra-Havreii of Utopia Planitia Fleet Yards on Mars, and was initially conceived for scientific exploration of the Gamma Quadrant following the discovery of the Bajoran wormhole. The project was sidelined by the impending threat from the Dominion and was suspended during the Dominion War, but was renewed soon afterwards.
In a rare exception, the class and registry of the Titan from the novels were referenced in the fourth edition of the Star Trek Encyclopedia (4th ed., vol. 2, p. 401). Included with the entry was an image of the Titan.
A competition to design the new vessel was held. Despite early conjecture that the Titan would be as large as its name suggested, the stipulations of the contest revealed that the ship was approximately 450 meters long, which was notably smaller than the last two starships Enterprise, and was only slightly bigger than the Intrepid-class. The contest rules established that within the novels' continuity, the Luna-class had a crew complement of 350 and was intended as an extended-mission, deep-space explorer, apparently as a result of Starfleet's efforts to get back on an exploration standing following the Dominion War.
The winning design was created by Sean Tourangeau and appeared similar to the Sovereign-class, but on a smaller scale, and with a "roll-bar" above the saucer section, similar to that found on the Akira-class. See the winning illustration on the .

In Star Trek Online, the Luna-class became so successful that by the early 25th century, it spawned three variants: the Comet-class, the Polaris-class, and the Sol-class. Following the Titan's appearance in Lower Decks, the model received a much-needed facelift in November 2020, as well as a new design variant christened the Titan-class.
