NX-Class starship

NX-01 Enterprise, the first NX-Class ship

The NX-Class Starship is an Earth Starfleet vessel, launched in 2151, with the Enterprise NX-01 being the first vessel launched in 2151.

## History

The NX-Class was a continuation of the Intrepid-class ship, with an evolution in starship design with a more complete saucer section, and an eye to the future with systems capable of being expanded with a mission-specific module attached under the saucer.

Henry Archer designed the ship around his revolutionary Warp-5 Engine, which could reach over 125 times the speed of light, theoretically 150 times light speed at maximum. The ship had 7 decks, mostly contained within the saucer section.

When launched in 2151, the Enterprise was considerably underpowered for its eventual needs in space. For much of 2151, the Enterprise traveled among the human colony worlds, and encountered the Andorians and Tellarites for the first time. Once its first year in space was finished, the Enterprise returned to Earth for a one-month refit.

The lessons learned with the Enterprise were transferred to the Columbia and Challenger, which were six-months behind in construction in comparison to the Enterprise. Additional phase cannons were installed on the following ships, as plasma cannons were less powerful overall. These ships would be designated the Mark 1a version of the ship, as the weaponry upgrades were not a significant-enough upgrade to consider it a completely new version of the ship.

In 2153, based on lessons learned with the Enterprise, Columbia, and Challenger, the Mark 2 version of the NX-class was created with a slightly more powerful warp engine that could sustain Warp 5 for 12 hours, and twice the number of phase cannons, covering additional firing arcs. Given the challenges with the Orions, Andorians, Xindi, and Kazathans, the Mark 2 was a necessary upgrade.

By 2155, however, the limitations of the class, and its need for refueling and resupply were showing themselves, and the final testing of the Warp 7 engine for the class was nearing completion. The Enterprise turned out to be the closest ship, already having been upgraded to a Mark 2 version, before returning to Earth for a 10-month refit to the Mark 3 NX-Class ship.

The Enterprise launched again in 2156 in time for the start of the Earth-Romulan War, with a new Warp 7 engine, 8 phase cannons (ventral fore, dorsal port/starboard, ventral aft), six photonic torpedo launchers (4 fore, 2 aft), and stronger polarized hull plating.

## Ships Built

### Mark I Version

This is the initial version of the NX-class ship, as built in 2151, with upgrades applied based on real-world experience of the Enterprise, including increased weaponry on the ship.

1. Enterprise, NX-01
2. Columbia, NX-02
3. Challenger, NX-03
4. Discovery, NX-04
5. Atlantis, NX-05
6. Endeavor, NX-06

#### Strength Index for Mark I

Torpedo Firepower : 0.5
Weapon Range and Accuracy : 15
Shield Strength : -
Hull Armour : 126.25
Speed : 65
 Overall Strength Index :

### Mark II Version

Given the hostilities encountered by the original group of 6 NX-class vessels, another group of vessels were ordered and constructed with spaceframes already near completion to help aid the protection of Earth and Earth colony shipping lanes.

1. Independence, NX-07
2. Explorer, NX-08
3. Pathfinder, NX-09
4. Dauntless, NX-10

#### Strength Index for Mark II Version

Torpedo Firepower : 18.75
Weapon Range and Accuracy : 30
Shield Strength : -
Hull Armour : 200.31
Speed : 65
 Overall Strength Index :

### Mark III Version

This version featured the secondary hull addition, long planned but finally implemented in 2156, with the Enterprise being the first ship to fly with it as a testbed. The refit took six months to install systems and refit the ship, which increased the deck count from 7 to 14, and the crew size to 140 persons. The speed was increased through the fitting of the Warp 7 engine to a cruising speed of Warp 6.2 and a maximum warp speed of Warp 7.3 for 1 hour.

The warp engines were altered to a 36° angle from the original 28°, and the new warp core was installed in the secondary hull. In the event of a warp core emergency, the Warp 7 core could be ejected with the secondary hull, and the Warp 7 core would come online to provide warp flight for the ship until it could return to a starbase for repair.

1. Confederation, NX-11
2. Cleburne, NX-12
3. Forrest, NX-13
4. Lee, NX-14
5. Washington, NX-15
6. Custis, NX-16
7. Hancock, NX-17
8. Virginia, NX-18
9. Montgomery, NX-19
10. Richmond, NX-20
11. Manassas, NX-21
12. Nashville, NX-22
13. Lynchburg, NX-23

During the Earth-Romulan War, all 23 NX-Class vessels were engaged, with 7 being destroyed, 3 damaged and retired from service, and the rest surviving past the war.
