Final flight of Antares 230+. With Russia's invasion of Ukraine in February 2022, the supply of Ukrainian-built first-stage airframes and Russian RD-181 engines was permanently severed; Northrop Grumman subsequently bought four Falcon 9 flights from SpaceX as a stopgap while developing the redesigned Antares 330 around new Firefly-built first stages.
