Lockheed Martin and NASA Fly X‑59 Quiet‑Supersonic Demonstrator on First Test

Overview

• Lockheed Martin reported the X‑59 completed its maiden sortie on October 29, flying from Plant 42 in Palmdale to a landing area near NASA’s Armstrong center at Edwards, California.
• The aircraft performed as planned, confirming basic flight characteristics and aerodynamic behavior before arriving at its new NASA base.
• NASA’s Quesst effort uses the X‑59 as an experimental platform to turn a traditional sonic boom into a softer sound intended to be less disruptive.
• Flight testing now transitions to envelope expansion with first supersonic runs planned in the coming months to reach target speeds and altitudes.
• Developers emphasize the X‑59 is a data‑gathering demonstrator rather than a prototype airliner, intended to inform future designs and potential rule changes.
