Mothership

"But the fact is, not much else on the battlefield compares to the mothership. With its ability to warp the fabric of space and time itself, this monster of a ship really is a weapon without equal."

- Jim Raynor

The mothership is a powerful protoss capital ship.

Overview
"By the heart of Aiur!"

- Protoss mothership commander

Motherships are mighty protoss support vessels, and are one of the most powerful warships in the protoss arsenal.

Design
Motherships are costly and time-consuming to produce. As a result, the protoss have begun constructing them in two stages, with the mothership core being the first step. The core itself can be used as a defensive and support weapon. Its hull, comprised of three slowly rotating wings, projects a tightly woven energy dome which allows for a life-sustaining atmosphere within the confines of the vessel, and turns harmful deep-space radiation into surplus energy for plasma shields and primary systems. The mothership’s core itself has a similar barrier whose sole function is to keep the crew on the rest of the ship safe from the powerful energies it generates.

A single crew member can pilot the ship for simple warps. More complex operations require a crew.

Capabilities
At the heart of each mothership is a huge khaydarin crystal infused with an incredible amount of psionic energy that quickly dissipates. By tapping into this energy, a mothership can warp or crack the very fabric of space-time itself. Once the mothership becomes fully operational, this dissipating power is absorbed by the wings and projected as a cloaking field that covers a wide area around the vessel. The mothership itself does not benefit from said field, but it renders nearby protoss forces, structures, and allies invisible to the naked eye.

For combat, the mothership is equipped with a purifier beam which constitutes its primary means of defense, firing in controlled bursts against air and ground targets. The devastating power of a mothership can wipe out squadrons of enemy ships in the blink of an eye or lay waste to entire planets. Other aspects of a mothership's interior include a waking chamber for its commander, crew quarters and a med-bay. A number of escape pods are also featured.

History
The motherships were designed by Juras, and constructed during the protoss Golden Age of Expansion as deep space exploration vessels, leading armadas of protoss ships through space. The Templar Caste successfully petitioned for modifications; the final design included weapons and some were eventually converted into military command ships.

Around 1500, a flaw was discovered in the khaydarin crystal cores of the motherships, causing two to fail in the gravity well of a neutron star and leading to the deaths of 8,463 protoss, one of the greatest loss of lives in the Golden Age. In response to the tragedy, the Khalai Caste developed two inventions, the technology allowing the motherships to mass recall away from danger, preventing another disaster like the neutron star incident, and the arkship, a massive ship that could be used prevent a similar random tragedy from also befalling the Protoss Empire as a whole.

The surviving motherships were not recalled at the end of the Golden Age. Most were left at the farthest reaches of protoss exploration as titanic monuments and holy shrines, commemorating an honored way of life and a proud period of history. The crews were placed in stasis, although it was expected the ships would not be needed again.

High templar Rihod's mothership remained active. Its crew assisted lower-technology aliens who had been struck by a disaster.

The Fall of Aiur
The zerg attack on Aiur during the Great War reversed forced a re-evaluation. The motherships were recalled to service by high templar Erekul. However, it was too late for the ships to alter the course of the war.

Amongst the reactivated ships was Moratun, the original mothership and crewed solely by Juras. Moratun rescued zealots from a besieged colony before traveling to Aiur. The ship, and other empty motherships, arrived in Aiur's star system only after the Khalai evacuation to Shakuras. The ships were forced to find the Dark Templar homeworld by themselves. The fleet was manned by the few survivors that could be found. Rihod's mothership was not brought to Aiur, for fear it could be lost in combat.

The motherships were reunited with the protoss during the Interbellum and taken over by the Templar Caste. Since their return from deep space, they have become an important part of the protoss war effort.

Game Unit
The mothership is a high-value support unit. Only one may be deployed at a time.

It behaves like the Arbiter: it cloaks and recalls friendly units, and may temporarily disable units. The ship's long ranged attack allows it to contribute firepower from behind the front; it may also fire on the move. The mothership is the only unit able to survive a direct hit from a nuke.

Vikings, corruptors, and void rays, are effective counters. It may also be hijacked by the infestor's neural parasite.

The mothership is suited for late-game scenarios. However, its use in multiplayer is curtailed by its high cost, position on the tech tree, vulnerability to focus firing, low mobility, and relatively low damage output.

Legacy of the Void
In the Legacy of the Void single-player campaign, the player acquires Tal'darim motherships that have significantly different statistics and abilities from the motherships available in multiplayer play. The normal mothership is not accessible in the campaign.

Abilities

 * Time Warp (T): This ability is only available in Heart of the Swarm, replacing Vortex. It affects enemy ground units in an area, forcing them to move at half speed. It costs 100 energy and lasts 10 seconds.
 * This ability has a range of 9 and an area of effect of 3.5.
