用法筆記

Common in technical and news contexts — especially in discussions of autonomous shipping, drone vessels, and uncrewed space exploration. In everyday conversation, 'unmanned' or 'autonomous' is more frequent. 'Crewless' is slightly more formal than 'uncrewed' and is the standard spelling in British maritime English.
