The Luna-class was a Federation reconnaissance science vessel starship type in service to Starfleet since the late 24th century. The Luna-class ships were the top of the line in Starfleet's scientific and exploratory pursuits on behalf of the United Federation of Planets. Each had an average crew of the 350 individuals and was approximately 450 meters long. Starfleet designed the Luna-class to accommodate the most diverse crew in the galaxy. By the early 25th century, the successful Luna-class spawned three variants, the Comet-, Polaris- and Sol-classes. (TTN novel: Taking Wing, ST video game: Star Trek Online)
The Luna-class was designed by Doctor Xin Ra-Havreii, of Utopia Planitia Fleet Yards on Mars, and 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, then restarted following the end of the Dominion War.
Their shuttlebays were reminiscent of the old Constitution-class shuttlebays, having a more rounded opening door. They also featured a longer "runway" for shuttles as they entered and exited the ship.
In the mirror universe, the Luna-class was a design in use by the Terran Empire. Imperial Starfleet categorized the Luna-class as a deep space science vessel (DSSV). When the Tholian Assembly accessed alternate timelines in the Azure Nebula, Federation Starfleet gained access to the Luna-class DSSV and added it to its ranks. (STO video game: Legacy of Romulus)
In the 25th century, the design of the Luna-class reconnaissance science vessel allowed its commanding officer to choose from different designs of livery, which could be modified further at starbases. These options were designated Type 1-5 and Veteran. (STO - "The Klingon War" mission: "Welcome to Earth Spacedock")
Furthermore, the installation of deflector shields from specific factions modified the hull appearance, including shields from the Reman Resistance, the Breen Confederacy and the Dominion. (STO missions: "Coliseum", "Cold Storage", "Boldly They Rode")
After the Borg Invasion of 2381, President Nanietta Bacco promised that more Luna-class ships would be built and that exploration would continue in the face of the recent disaster. (ST - Destiny novel: Lost Souls)

Star Trek Nemesis established William T. Riker's new command, the USS Titan, but offered no information about that ship. When Pocket Books launched the Star Trek: Titan book series, they held a competition to design the new Luna class. The winning design by Sean Tourangeau was announced on October 6, 2005. Tourangeau then worked with artist Ellery O'Connell to develop a 3D model of the Titan, which debuted on the cover of the fourth Titan novel, Sword of Damocles.
