Editing Emergency thruster

{{Era|UNSC|HCW}}

'''Emergency thrusters''' are standard equipment on [[United Nations Space Command|UNSC]] vessels, serving as emergency one-use [[maneuver drive]]s. They are often the reason a UNSC ship is able to escape a confrontation unscathed. These thrusters are used only in dire situations; for instance, to dodge enemy fire where the [[Fusion drive|standard propulsion systems]] would not be able to do so. They consist of strategically placed tanks on the ship's outer hull, containing [[trihydride tetrazine]] and [[Wikipedia:Hydrogen peroxide|hydrogen peroxide]]. These substances, when mixed, produce significant explosive force to blast the ship onto a new course.{{Ref/Novel|Halo: The Fall of Reach<!--|Page=149-->}} However, the thruster is expended in the process and must be replaced in a ship dock before it can be used again. The real-world term for this reaction would be a hypergolic propellant, which is used in some of today's modern spacecraft.

The {{UNSCShip|Iroquois}} had six of these devices on it. Two of them were used during the [[Battle of Sigma Octanus IV]], the first during the performance of the "[[Keyes Loop]]" in order to cause several [[Plasma turret|Plasma Torpedoes]] to hit a [[Covenant destroyer|Covenant Destroyer]], the second time to blast the ''Iroquois'' out of the gravity well of [[Sigma Octanus IV]]. The ''[[UNSC Pillar of Autumn|Pillar of Autumn]]'' also had several of these, though "the portside emergency thrusters were missing".{{Ref/Novel|Halo: The Fall of Reach<!--|Page=271-->}} However, this is a discrepancy, because they are later used twice.{{Ref/Novel|Halo: The Fall of Reach<!--|Page=292-->}}{{Ref/Novel|Halo: The Fall of Reach<!--|Page=320-->}}
