Editing Thrust vectoring (section)

====Gimbaled thrust====
{{main|gimbaled thrust}}
Thrust vectoring for many [[liquid rocket]]s is achieved by [[gimbaled thrust|gimbal]]ing the whole [[rocket engine|engine]]. This involves moving the entire [[combustion chamber]] and outer engine bell as on the [[Titan II]]'s twin first-stage motors, or even the entire engine assembly including the related [[fuel pump|fuel]] and [[oxidizer]] pumps. The [[Saturn V]] and the [[Space Shuttle]] used gimbaled engines.<ref name="Sutton" />

A later method developed for [[solid rocket propellant|solid propellant]] [[ballistic missile]]s achieves thrust vectoring by deflecting only the [[rocket nozzle|nozzle]] of the rocket using electric actuators or [[hydraulic cylinder]]s. The nozzle is attached to the missile via a [[ball joint]] with a hole in the centre, or a flexible seal made of a thermally resistant material, the latter generally requiring more [[torque]] and a higher power actuation system. The [[UGM-96 Trident I|Trident C4]] and [[UGM-133 Trident II|D5]] systems are controlled via hydraulically actuated nozzle. The [[Space Shuttle Solid Rocket Booster|STS SRB]]s used gimbaled nozzles.<ref name=RSRM-ALCS>{{cite journal |title=Reusable Solid Rocket Motor—Accomplishments, Lessons, and a Culture of Success |url=https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20120001536.pdf |website=ntrs.nasa.gov |date=27 September 2011 |access-date=February 26, 2015 |archive-date=4 March 2016 |archive-url=https://web.archive.org/web/20160304210207/http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20120001536.pdf |url-status=live }}</ref>
