As an interim solution, Northrop Grumman contracted with its CRS competitor SpaceX to launch NG-20, 21 and 22 using its Falcon 9 rocket. To accommodate the Cygnus, SpaceX modified their payload fairing to add a 5 ft × 4 ft (1.5 m × 1.2 m) side hatch to load late cargo onto the spacecraft from the cleanroom located at the end of the crew ...
Northrop Grumman NASA (CRS) Success Cygnus NG-12 is the first mission under the NASA Commercial Resupply Services-2 contract.

In August 2023, Northrop Grumman announced a further enlarged Mission B version of Cygnus, with a 1.5 m (4.9 ft) stretch to the payload module and payload mass increased to 5,000 kg (11,000 lb). This version is expected to enter service with the NG-23 mission in 2025 (the first to use the new Antares 330 launch vehicle).
The Taurus launch vehicle, later renamed [1] Minotaur-C (for "Minotaur-Commercial"), was the first of the Minotaur vehicle family, and the first ground-launched orbital booster developed by Orbital Sciences Corporation (OSC), derived by adding a solid booster stage to the air-launched Pegasus rocket.
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.
The GEM 63XL, developed by Northrop Grumman, is an extended version of the GEM 63, about 73 inches (190 cm) longer than its predecessor. [7] The weight is approximately 117,000 pounds (53 metric tons) each. [8] First fired in 2020, it is used on the Vulcan launch vehicle beginning with the first launch on January 8, 2024.
In 2004, Northrop Grumman [N 1] used the second YF-23 as a display model for its proposed regional bomber aircraft, but this project was dropped because longer range bombers were required. The two YF-23 prototypes are currently exhibits at the National Museum of the United States Air Force and the Western Museum of Flight respectively.
NG-13, previously known as OA-13, was the fourteenth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its thirteenth flight to the International Space Station (ISS) under the Commercial Resupply Services (CRS-1) contract with NASA. [4] [5] The mission launched on 15 February 2020 at 20:21:01 UTC after nearly a week of ...
