Cygnus XL is the third major cargo-module configuration of Northrop Grumman's Cygnus spacecraft. Introduced on NG-23 in 2025, its enlarged pressurized cargo module provides about 38 cubic metres of volume and capacity for roughly 5,000 kilograms of cargo while retaining Cygnus autonomous rendezvous, station berthing, reboost, and expendable disposal capabilities.
