X-59 Takes Flight: First Supersonic Hurdle Cleared
1 Jun
Summary
- X-59's first supersonic flight achieved speeds over 630 mph.
- The aircraft will aim for Mach 1.4 at 55,000 feet.
- New test flights gather data for NASA's quiet supersonic mission.
NASA's experimental X-59 aircraft is entering a critical phase of testing, with upcoming flights set to surpass the sound barrier for the first time. These tests aim to achieve speeds exceeding 630 mph at approximately 43,000 feet. The program is moving towards "mission conditions" tests, targeting Mach 1.4 (925 mph) at around 55,000 feet.
These performance goals align with NASA's Quesst mission, which seeks to evaluate public response to the aircraft's quieter sonic "thump." While these initial supersonic flights are not designed to demonstrate noise reduction, a chase aircraft will accompany the X-59 to gather data on its shock waves. Previous flight testing, beginning in October 2025 and resuming in March 2026, successfully met key objectives, including reaching altitudes of 43,000 feet and speeds near Mach 0.95.
The upcoming flights will challenge the X-59 in true supersonic conditions, pushing its performance envelope toward its maximum targets of Mach 1.6 and 60,000 feet. Data collected will inform Phase 2 of the Quesst mission, scheduled to begin later in 2026, focusing on directly measuring the quiet supersonic signature. These advancements mark progress toward the future of commercial supersonic travel.
