== Operational examples == ===Aircraft=== [[File:Vector-nozzle-sea-harrier-jet-common.jpg|thumb|[[Sea Harrier]] FA.2 ''ZA195'' front (cold) vector thrust nozzle]] An example of 2D thrust vectoring is the [[Rolls-Royce Pegasus]] engine used in the [[Hawker Siddeley Harrier]], as well as in the [[AV-8B Harrier II]] variant. Widespread use of thrust vectoring for enhanced maneuverability in Western production-model fighter aircraft didn't occur until the deployment of the [[Lockheed Martin]] [[F-22 Raptor]] fifth-generation jet fighter in 2005, with its afterburning, 2D thrust-vectoring [[Pratt & Whitney F119]] [[turbofan]].<ref name="F-22_factsheet">[https://web.archive.org/web/20121103231508/http://www.af.mil/information/factsheets/factsheet.asp?id=199 "F-22 Raptor fact sheet."] ''U.S. Air Force'', March 2009. Retrieved: 10 July 2014.</ref> [[File:F-35B short takeoff from HMS Prince of Wales.jpg|thumb|A [[Royal Navy]] F-35B taking off with thrust-vectored nozzle.]] While the [[F-35 Lightning II|Lockheed Martin F-35 Lightning II]] uses a conventional afterburning turbofan (Pratt & Whitney F135) to facilitate supersonic operation, its F-35B variant, developed for joint usage by the [[US Marine Corps]], [[Royal Air Force]], [[Royal Navy]], and [[Italian Navy]], also incorporates a vertically mounted, low-pressure shaft-driven remote fan, which is driven through a clutch during landing from the engine. Both the exhaust from this fan and the main engine's fan are deflected by thrust vectoring nozzles, to provide the appropriate combination of lift and propulsive thrust. It is not conceived for enhanced maneuverability in combat, only for [[VTOL]] operation, and the F-35A and F-35C do not use thrust vectoring at all. The [[Sukhoi Su-30MKI]], produced by India under licence at [[Hindustan Aeronautics Limited]], is in active service with the [[Indian Air Force]]. The TVC makes the aircraft highly maneuverable, capable of near-zero airspeed at high angles of attack without stalling, and dynamic aerobatics at low speeds. The [[Su-30MKI]] is powered by two [[Al-31FP]] [[afterburning]] [[turbofan]]s. The TVC nozzles of the MKI are mounted 32 degrees outward to longitudinal engine axis (i.e. in the horizontal plane) and can be deflected Β±15 degrees in the vertical plane. This produces a [[corkscrew]] effect, greatly enhancing the turning capability of the aircraft.<ref>{{cite web |url=http://www.air-attack.com/page/80/Su-30MK.html|title=Air Attack - Fighters and more|website=www.air-attack.com |url-status=dead |archive-url=https://web.archive.org/web/20100917182438/http://air-attack.com/page/80/Su-30MK.html|archive-date=2010-09-17 }}</ref> A few computerized studies add thrust vectoring to extant passenger airliners, like the Boeing 727 and 747, to prevent catastrophic failures, while the experimental [[Boeing X-48|X-48C]] may be jet-steered in the future.<ref name=galor>{{cite journal |last=Gal-Or |first=Benjamin |title=Future Jet Technologies|journal=International Journal of Turbo and Jet Engines|year=2011|volume=28|pages=1β29 |location=online |doi=10.1515/tjj.2011.006 |s2cid=111321951 |issn=2191-0332}}</ref> ===Other=== Examples of rockets and missiles<ref>https://patents.google.com/patent/US7509797B2</ref> which use thrust vectoring include both large systems such as the [[Space Shuttle Solid Rocket Booster]] (SRB), [[SA-10 Grumble|S-300P (SA-10)]] [[surface-to-air missile]], [[UGM-27 Polaris]] [[nuclear weapon|nuclear]] [[ballistic missile]] and [[SS-24|RT-23 (SS-24)]] ballistic missile and smaller battlefield weapons such as [[Swingfire]]. The principles of air thrust vectoring have been recently adapted to military sea applications in the form of fast water-jet steering that provide super-agility. Examples are the fast patrol boat [[Super Dvora Mk III-class patrol boat|Dvora Mk-III]], the [[Hamina class missile boat]] and the US Navy's [[Littoral combat ship]]s.<ref name=galor/>
