As an interim solution, Northrup Grumman contracted with its CRS competitor SpaceX to launch NG-20, 21 and 22 using its Falcon 9 Block 5 rocket. With the launch of NG-20, Cygnus becomes only cargo freighter to launch on four different orbital launchers, that is, Antares rocket (100 series), Atlas V , Antares 200 series and Falcon 9.
As a result Russia's invasion of Ukraine, Northrop Grumman was left with only two remaining Antares 230+ launch vehicles which were used for the CRS NG-18 and CRS NG-19 missions.
