CLASS INFORMATION:
The Saber-class starship was introduced in 2370 as part of Starfleet’s initiative to create a new generation of ships to combat any future Borg incursions after the defeat at Wolf 359. Designed primarily for reconnaissance, patrol and escort duties, the Saber’s maneuverability and versatility make it a reliable combat vessel.
Twice the size of the Defiant-class, the Saber-class shares many of the design features of its little sister, as well as of the larger Steamrunner-class. Its compact design allows it to maintain faster impulse speeds and turn more tightly than other, larger ships. The Saber needs this speed, as its design features a weaker hull than other Starfleet vessels and less shield power than most other ships. Nevertheless, Saber-class vessels played a key role in repelling the second Borg incursion in 2373.
Seeing how the Saber is a smaller version of the Steamrunner, here are some Steamrunner floorplans:
