Cygnus NG-14 (Northrop Grumman-14) is a cargo resupply mission of the Northrop Grumman Cygnus spacecraft to the International Space Station under the Commercial Resupply Services (CRS) contract with NASA. The cargo will also launch the European Bartolomeo platform to the ISS. It will be docked to the Colombus European module.

Northrop Grumman and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station. The Cygnus cargo ship consists of two parts, a service module built in the USA based on the GEOStar platform, and a pressurized module, manufactured in France and Italy by Thales Alenia. The cargo is sent into orbit by a launcher specially developed for this purpose.

Antares has a first stage based on Energiya lateral blocks, made in Ukraine by Yuzhnoye. It was initially powered by two NK-33s, built in the 1960s for the Soviet N1 lunar launcher, before being replaced by RD-181s, derived from the RD-170s installed on Energiya and Zenit. The second stage, a Castor-30, is made in the USA, by Northrop Grumman.

Its stay on the ISS was 113 days. It was unberthed on 06/01/2021 at 12:15 UTC and released by RMS on 06/01/2021 at 15:11 UTC. It deorbited on 26/01/2021 at 20:23 UTC.
