==History==
In 2020, ABL Space Systems was planning the first orbital launch of its RS1 rocket in 2022. The firm received contracts worth US$44.5 million from the [[United States Air Force]], as well as private funding equaling US$49 million.

===Previous design===
In 2019, RS1 was planned to have three E1 engines, each producing {{cvt|42000|lbf|order=flip}} of thrust to power the rocket's first stage. A single E2 engine, with {{cvt|13000|lbf|order=flip}} of thrust, was planned for the rocket's second stage. Both engines would use liquid oxygen and RP-1 propellants. The first development build of the vehicle has been completed.<ref>{{cite web|date=1 February 2019|first=Jeff|last=Foust|title=ABL Space Systems increases performance and cuts price of its small launch vehicle |url=https://spacenews.com/abl-space-systems-increases-performance-and-cuts-price-of-its-small-launch-vehicle/ |access-date=15 February 2021|publisher=[[SpaceNews]]}}</ref>

==Testing==
In 2019, ABL Space conducted testing of the [[E2 rocket engine]] at the company's test facilities at Spaceport America, New Mexico, which "provided the perfect location and support staff for us to test the E2 rocket engine". The test was considered a success.<ref name="Spaceport">{{cite news |last1=Clark |first1=Carol A. |title=Spaceport America announces test operations of ABL Space Systems |url=https://ladailypost.com/spaceport-america-announces-test-operations-of-abl-space-systems/ |access-date=16 November 2021 |agency=Los Alamos Daily Post |date=29 December 2019 |archive-date=16 November 2021 |archive-url=https://web.archive.org/web/20211116124712/https://ladailypost.com/spaceport-america-announces-test-operations-of-abl-space-systems/ |url-status=live }}</ref>

| colspan="8" |First flight of the RS1 launch vehicle. The vehicle suffered an anomaly shortly after liftoff and was destroyed. Failure was attributed to an overly restrictive launch mount and flame diverter causing plume recirculation and overloading of headshield causing fire. Fire subsequently caused damage to key harnesses causing loss of power and simultaneous loss of thrust in all engines due to de-energization of valves.<ref>{{cite web |title=FAA Closes RS1 Mishap Investigation |url=https://ablspacesystems.com/news/faa-closes-rs1-mishap-investigation/ |website=ablspacesystems.com |publisher=ABL |access-date=7 November 2023}}</ref>
