The story
Founded by Paul Allen in 2011.1
The project was started in 2010, almost a year before the public announcement was made. Development costs were initially projected to be US$300 million in 2011. Dynetics actually began work in early 2010 and had approximately 40 employees working on the project as of December 2011. Dynetics was cited as "responsible for the total systems engineering, integration and testing, which includes aerodynamics, loads, and interfaces". It was announced in 2011 that SpaceX was also already working on the design for the rocket-powered space vehicle components of the system, the Falcon 9 Air.
The collaboration with SpaceX ended by 2012. In a 2015 interview, former president Chuck Beames (2014–2016) explained, "SpaceX was a partner, and like a lot of partnerships, it was just determined that it was best we went our separate ways – different ambitions. We were interested in their engines, but Elon and his team, they're about going to Mars, and we're just in a different place, and so I think it was a parting of the ways that was amicable".
Stratolaunch Systems completed its first 88,000 sq ft (8,200 m2) composites production building in October 2012. In February 2013, the company completed construction of its 92,640 sq ft (8,607 m2) carrier assembly hangar and operations facilities at the Mojave Air and Space Port.
The carrier aircraft was originally projected to make its first test flight in 2015. By October 2013, the first flight of the carrier aircraft was pushed back until 2018 at the earliest, with the first flight of the air-launched rocket expected in 2019 at the earliest.
In 2014, Stratolaunch announced that it was considering multiple launch vehicle options over a range of satellite sizes, and that some development work on the orbital launch vehicle has been slowed down to focus on completion of the carrier aircraft.
In 2014, Stratolaunch Systems was placed under the supervision of Paul Allen's new aerospace company Vulcan Aerospace, a subsidiary of Vulcan Inc. Beames stated, "Vulcan Aerospace is the company within Vulcan that plans and executes projects to shift how the world conceptualizes space travel through cost reduction and on‐demand access. Vulcan Aerospace has its heritage in SpaceShipOne and oversees the Stratolaunch Systems project"
Later in the year, in November 2015, Gary Wentz "stepped down as president and CEO of Stratolaunch Systems to join United Launch Alliance to lead human launch services" for ULA. Vulcan ended its contract with Orbital ATK in mid-2015 and indicated that a decision on a new rocket for the Stratolaunch Carrier Aircraft would be made in late 2015.
In 2017, Fast Company named the Stratolaunch one of the world's most innovative companies citing the air-launch system's size and ability to fly in inclement weather. In April 2017, Stratolaunch formally transitioned its name from Vulcan Aerospace to Stratolaunch Systems Corporation.

In May 2017, the Stratolaunch was rolled out for the first time to begin fueling tests, the first of many ground tests.
In December 2017, the Stratolaunch was rolled out for the first taxi test on the runway at the Mojave Air and Space Port in California. On April 13, 2019, Stratolaunch took to the air for the first time and flew for two and a half hours from the Mojave Air and Space Port. The flight reached a maximum altitude of 4,570 meters and a top speed of 278 kilometers per hour.
In January 2019, Stratolaunch announced it was halting development of its own air-launched family of launch vehicles. This followed the Allen's death in October 2018, who had been the source of funds for the capital intensive development program since its founding in 2011. In April 2019, Jean Floyd remained CEO of Stratolaunch.
The carrier first flew in April 2019, at the Mojave Air and Space Port, reaching 15,000 ft (4,600 m) and 190 mph (305 km/h) during a 2 hour 29 minute flight.
On 31 May 2019, it was reported that the company would cease operations and sell its assets. In the event, the company remained in operation and posted job openings, including listings for test pilots, in September 2019. Stratolaunch rapidly grew their staff from 13 employees in October 2019 to 87 employees by mid-December 2019, later reaching 360 employees and contractors.
Stratolaunch underwent a change of direction when Jean Floyd became CEO in 2019, reacquiring staff and growing to 87 employees by the beginning of 2020. Zachary Krevor became president and CEO in March 2022. Krevor was previously vice president of engineering.
