The Death Fleet is a protoss fleet based on Slayn. Comprised of a number of Tal'darim vessels, it was constructed to serve Amon's will to eradicate all life in the sector at his command. It later came to serve as the Tal'darim aerospace force.
The Death Fleet was formed under the command of the Tal'darim Highlord Ma'lash. The fleet maintained orbit over the Tal'darim homeworld of Slayn, ready to move at a moment's notice for a full-scale invasion. The fleet comprised a number of destroyers, carriers, and motherships. The fleet is commanded by powerful fleet lords, who oversee the destruction of their foes from the bridges of their motherships.
During the End War, First Ascendant Alarak came to Slayn with Hierarch Artanis, and with his aid, overthrew Ma'lash to rule the Tal'darim. Under Alarak's command, the Death Fleet subsequently joined with the Daelaam to fight against Amon, and Alarak deployed them in his fight against Amon's Forces. In the final stages of the End War, the Death Fleet finally arrived to Aiur with the Purifier, Nerazim and Khalai fleets. Together they bombarded Amon's host form, destroying it. Later, the Tal'darim fleet provided defense against Amon's zerg brood and the corrupted protoss of the Golden Armada, until the xel'naga Keystone activated, freeing the Templar.
Into the Void
In the war's aftermath, Alarak remained in command of the Death Fleet. At his direction, the Death Fleet struck at unsuspecting worlds, claiming their technology and resources.
The Defenders of Man
Years later, the Death Fleet arrived at Tyrador IX to exterminate the Defenders of Man for destroying a remote Tal'darim outpost and then escaping before the Tal'darim could retaliate, though they were stopped by Dominion forces. Alarak vowed retribution against the Defenders of Man, and struck a bargain with Nova Terra in order to locate them.
After Vardona was discovered to be the Defenders of Man stronghold and General Carolina Davis their leader, Alarak unleashed the Death Fleet on the world. Dominion soldiers, Defenders of Man, and civilians alike were caught in the Tal'darim's fury. However, though Alarak and Nova had made a bargain, she refused to allow him to harm civilians, and opposed his attack. Dominion forces, Nova's Covert Ops Crew, and low ranking Defenders of Man all united to push back the Death Fleet, forming a defensive line as they poured through the city. The line held back the Tal'darim's initial pushes, and soon the Dominion Fleet arrived, using Gorgon-class battlecruisers to strafe the attack lanes. Ji'nara attempted to throw motherships against the terran defenses, but to no avail. After heavy casualties, the Death Fleet was forced to withdraw. Alarak contacted Nova in the aftermath, stating she had just made a powerful enemy for her betrayal, and Nova replied that he had as well.
The Fall of Spearpoint Base
Sometime after the End War, the Tal'darim were contacted by a renegade Nerazim, who led them to a Umojan Protectorate world named Aeneas where anti-protoss weapons were being developed. The Tal'darim dispatched the Death Fleet, and besieged the world. In a fierce battle, the Death Fleet annihilated the defenders and purified the base. However, over the course of the battle, a terran ship containing a powerful protoss power source rammed into one of the Death Fleet's motherships, destroying both in a cataclysmic explosion.
In Co-op Missions, Alarak can summon the Death Fleet as a calldown ability, unlocked at Level 10. It summons a mothership and four destroyers to fight for 60 seconds. At level 13 the ability is upgraded to summon eight destroyers, and allow the mothership to use its Thermal Lance ability.
