Cygnus NG-22

Maiden flight of Antares 330 — the substantially redesigned vehicle Northrop Grumman developed jointly with Firefly Aerospace after the 2022 supply break severed Ukrainian airframe and Russian RD-181 engine deliveries. The new first stage is US-built, powered by seven Firefly-developed Miranda engines, and raises Antares's payload capacity well above the 230+ generation.
