The Majestic-class was a type of starship that entered service with the Federation Starfleet during the last quarter of the 24th century, classified as a deep-range explorer. The lead ship was launched in 2379. (Journal of Applied Treknology)
The class was designed as a replacement for the aging Ambassador-class and Excelsior-class vessels still in service after the Dominion War, and its mission profile was intended primarily for diplomatic assignments.
The Majestic class was designed by Malcom "Galen" Lu. A version of the class exists in Obsidian Fleet continuity, but while using the diplomatic ship concept, OF's Majestic class is smaller, classified as a frigate, and utilizes images of Lu's Legacy-class starship design.
