 ## Features/Improvements
 
+* **[Factions]** Replaced Patriot STRs "EWRs" with AN/FPS-117 for blue factions 1980 or newer.
 * **[Mission Planning]** Per-flight TOT offsets can now be set in the flight details UI. This allows individual flights to be scheduled ahead of or behind the rest of the package.
