NX was a material option, an Alpha Quadrant Alliance designation for the visual appearance of a spacecraft's outer hull, i.e. a vessel's "skin". This version of NX was available for select Federation Starfleet starships from 2409 onwards. This material was based on the NX-class escort.
In 2410, following the return of J'Ula, this material was made available to tier 3 and tier 6 heavy cruiser classes - cruisers with quad nacelle configuration like the Cheyenne and Stargazer-class. (STO - Legacy mission: "Welcome to Earth Spacedock")
- With the PC Patch Notes for 01/28/20, the NX skin became available for the Federation Heavy Cruiser classes.
