Falcon 9 v1.1 is the second version of SpaceX's Falcon 9 orbital launch vehicle. The rocket was developed in 2011–2013, made its maiden launch in September 2013, and its final flight in January 2016. It was designed, manufactured, and operated by SpaceX. Following the second Commercial Resupply Services (CRS) launch, the initial version of the Falcon 9, the v1.0, was retired from use with the v1.1 replacing it. Falcon 9 v1.1 was scheduled to launch crew for NASA under a 2014 contract that enables private organizations to launch crew to the ISS but, in the event, those launches will now be accomplished on a Falcon 9 full thrust version, first flown in December 2015.
