[[Company:SpaceX|SpaceX]] manufactures [[Engineering:Launch vehicle|launch vehicle]]s to operate its [[Engineering:Launch service provider|launch provider services]] and to execute its various exploration goals.

As of 2024, the company is also developing the fully reusable [[Engineering:SpaceX Starship|Starship]] launch system, which will replace Falcon 9, Falcon Heavy, and Dragon.<ref>{{Cite web |last=Berger |first=Eric |date=November 18, 2024 |title=SpaceX president predicts rapid increase in Starship launch rate |url=https://arstechnica.com/space/2024/11/spacex-president-predicts-rapid-increase-in-starship-launch-rate/ |access-date=November 18, 2024 |website=Ars Technica |language=en-US}}</ref>

SpaceX's first launch vehicle, the [[Engineering:Falcon 1|Falcon 1]], was the first [[Engineering:Private spaceflight|privately developed]] liquid fueled launch vehicle to be launched into orbit, and used SpaceX's Merlin and Kestrel engines for its first and second stages, respectively. It was launched five times from Omelek Island between 2006 and 2009 – the [[Engineering:Falcon 1e|Falcon 1e]] and [[Engineering:Falcon 5|Falcon 5]] variants were planned but never developed. The [[Engineering:Falcon 9 v1.0|Falcon 9 v1.0]], using upgraded Merlin engines on both its stages, was developed as part of the United States Air Force's [[Engineering:National Security Space Launch|Evolved Expendable Launch Vehicle]] program and [[Organization:NASA|NASA]]'s [[Astronomy:Commercial Orbital Transportation Services|Commercial Orbital Transportation Services]] program. It was first launched from Cape Canaveral in 2010 and later replaced by the [[Engineering:Falcon 9 v1.1|Falcon 9 v1.1]] series in 2013, which was also launched from Vandenberg Air Force Base in California. The [[Engineering:Falcon 9 Full Thrust|Falcon 9 Full Thrust]] and [[Engineering:Falcon Heavy|Falcon Heavy]] variants followed in 2015 and 2018. Falcon Heavy launches from Kennedy Space Center in Florida, and Falcon 9 additionally launches from Cape Canaveral Space Force Station in Florida and Vandenberg.

== Nomenclature ==
[[Biography:Elon Musk|Elon Musk]], CEO of SpaceX, has stated that the Falcon 1, 9, and Heavy are named after the ''[[Engineering:Millennium Falcon|Millennium Falcon]]'' from the ''Star Wars'' film series.<ref>{{cite web |url= https://www.youtube.com/watch?v=hwMIAKabRng |title= Joseph Gordon-Levitt at SpaceX |publisher= Youtube |page= timeindex 2:25 }}</ref>

{{Main|Engineering:Falcon Heavy}}
{{stack|[[File:Falcon Heavy cropped.jpg|thumb|Falcon Heavy on pad LC-39A.]]}}
Falcon Heavy (FH) is a [[Engineering:Super heavy-lift launch vehicle|super heavy lift space launch vehicle]] designed and manufactured by [[Company:SpaceX|SpaceX]]. The Falcon Heavy is a variant of the [[Engineering:Falcon 9|Falcon 9]] launch vehicle comprising three Falcon 9 first stages: a reinforced center core, and two additional [[Engineering:Modular rocket|side boosters]]. All three boosters are capable of being recovered and reused, although most flights use unrecoverable stripped-down center cores to increase performance. The side boosters assigned to Falcon Heavy's first flight were recovered from two prior Falcon 9 missions. SpaceX successfully launched the Falcon Heavy on February 6, 2018, delivering a payload comprising Musk's [[Engineering:Elon Musk's Tesla Roadster|personal Tesla Roadster]] onto a trajectory reaching the orbit of Mars.<ref>{{cite web |url=https://www.cbsnews.com/news/watch-live-falcon-heavy-launch-spacex-online-stream-live-updates/ |title=SpaceX Falcon Heavy launch puts on spectacular show in maiden flight |publisher=CBS News |date=February 6, 2018 |access-date=February 6, 2018 |first=William |last=Harwood }}</ref>

{{Main|Engineering:Falcon 9 Full Thrust}}
The "Full Thrust" version of Falcon 9 is an upgraded version of the Falcon 9 v1.1. It was used the first time on December 22, 2015, for the ORBCOMM-2 launch at Cape Canaveral SLC-40 launch pad.<ref name="sn20150915">{{cite web |last1=Foust |first1=Jeff |date=September 15, 2015 |title=SES Betting on SpaceX, Falcon 9 Upgrade as Debut Approaches |url=http://spacenews.com/ses-betting-on-spacex-falcon-9-upgrade-as-debut-approaches/ |access-date=September 19, 2015 |publisher=SpaceNews}}</ref>

The first stage was upgraded with a larger [[Physics:Liquid oxygen|liquid oxygen]] tank, loaded with subcooled propellants to allow a greater mass of fuel in the same tank volume. The second stage was also extended for greater fuel tank capacity. These upgrades brought a 33% increase to the previous rocket performance.<ref>{{cite web |url=https://www.youtube.com/watch?v=O5bTbVbe4e4 |title=ORBCOMM-2 Full Launch Webcast |date=December 21, 2015 |author=SpaceX |website=[[Company:YouTube|YouTube]] }}</ref> Five sub-variants have been flown; only [[Engineering:Falcon 9 Block 5|Falcon 9 Block 5]] is still active.<ref>{{Cite web |last=Berger |first=Eric |date=June 28, 2018 |title=SpaceX has flown its last Block 4 version of the Falcon 9 rocket [Updated] |url=https://arstechnica.com/science/2018/06/spacex-set-to-fly-its-final-block-4-version-of-the-falcon-9-on-friday/ |access-date=December 30, 2024 |website=Ars Technica |language=en-US}}</ref>

On September 8, 2005, SpaceX announced the development of the [[Engineering:Falcon 9|Falcon 9]] rocket, which has nine Merlin engines in its first stage.<ref name="SpaceX Press 2005-09-08"/> The design is an [[Engineering:Evolved Expendable Launch Vehicle|EELV]]-class vehicle, intended to compete with the Delta IV and the Atlas V, along with launchers of other nations as well. Both stages were designed for reuse.

The first version of the Falcon 9, [[Engineering:Falcon 9 v1.0|Falcon 9 v1.0]], was developed in 2005–2010, and flew five orbital missions in 2010–2013. The second version of the launch system—[[Engineering:Falcon 9 v1.1|Falcon 9 v1.1]]—has been retired meanwhile.

Falcon 9 v1.1 was developed in 2010–2013, and made its maiden flight in September 2013.

The first stage of Falcon 5 was to be powered by five Merlin engines, and the upper stage by one Merlin engine, both burning [[Chemistry:RP-1|RP-1]] with a [[Physics:Liquid oxygen|liquid oxygen]] oxidizer. Along with the [[Engineering:Falcon 9|Falcon 9]], it would have been the world's only launch vehicle with its first stage designed for reuse.<ref>{{cite press release |url = http://www.spacex.com/press.php?page=18 |title = SpaceX announces the Falcon 9 fully reusable heavy lift launch vehicle |date = September 8, 2005 |publisher = SpaceX |access-date = March 26, 2013 |archive-url = https://web.archive.org/web/20130326183411/http://www.spacex.com/press.php?page=18 |archive-date = March 26, 2013 |url-status = dead |df = dmy-all}}</ref>

The Falcon 5 would have been the first American rocket since the [[Engineering:Saturn V|Saturn V]] to have full engine-out capability, meaning that with the loss of one engine, it can still meet mission requirements by burning the other four engines longer to achieve the correct orbit.<ref name="Wade Falcon V">

'''Falcon 9 Air''' would have been an [[Astronomy:Air launch to orbit|air-launched]] multi-stage [[Engineering:Launch vehicle|launch vehicle]] under [[Engineering:New product development|development]] by SpaceX in 2011–2012. Falcon 9 Air was to be carried to launch position and launch altitude by a [[Company:Stratolaunch Systems|Stratolaunch Systems]] carrier aircraft, the world's largest aircraft by wingspan. Payload to [[Astronomy:Low Earth orbit|low Earth orbit]] was projected to be {{convert|6100|kg|lb|abbr=in}}.

Propulsion for the rocket was planned to be provided by four Merlin 1D rocket engines, engines that were also to be used in the [[Engineering:Falcon 9 v1.1|Falcon 9 v1.1]] beginning in 2013, and also on the [[Engineering:Falcon Heavy|Falcon Heavy]] in 2014. Its first flight was notionally planned for 2016.

In December 2011 [[Company:Stratolaunch Systems|Stratolaunch Systems]] announced that it would contract with SpaceX to develop an [[Astronomy:Air launch to orbit|air-launched]], multiple-stage [[Engineering:Launch vehicle|launch vehicle]], as a derivative of Falcon 9 technology, called the Falcon 9 Air,<ref name=ss20111220>
