This is an original ship design, the USS Stronghold, Goliath class. It's a Starfleet battleship. After the Dominion War, and the hundreds of ships lost, they decided to toughen up. Not all races in the universe are peaceful, and Starfleet wants to be prepared. The ship isn't necessarily bigger, but it is thicker. It is both heavily armed and armored. It's equipped with the latest shield enhancements and ablative hull armor. It has six torpedo launchers, four forward launchers next to the deflector dish, and two aft next to the secondary shuttlebay. There are multiple phaser arrays all over the hull represented with dark gray plates. Most impressive is the Isokinetic Pulse Cannon that Starfleet designed based on the specs Voyager brought back from the Delta Quadrant. It's mounted on the front of the saucer section. The saucer does separate from the engineering section, and that was the final touch for this model.
