NX-337-C, Fictional Starfleet Dreadnought Design

U.S.S. Markarius / NX-337-C
Markarius-Class Heavy Temporal Dreadnought

The goal was to create a starfleet ship that remains unmistakably Starfleet, but not gentle.
The Markarius-C combines clean Federation paneling, 32nd-century floating architecture, heavy dreadnought massing, transformable mission structures, and a unified hull-wide phaser system.
It is meant to feel like a Starfleet capital ship built for the most extreme missions: part explorer, part temporal response platform, part mobile fortress, part carrier, and part fleet command ship.
