A historic milestone as the X-59 QueSST aircraft achieves supersonic speed for the first time.

GD&TĐ - Lockheed Martin's latest experimental aircraft, the X-59 QueSST, has achieved supersonic speed for the first time.

The X-59 QueSST was created as part of the "quiet supersonic aircraft" program, according to NASA.

The test flight is a significant milestone on the path to demonstrating quiet supersonic flight technology, which is expected to be deployed this year.

NASA test pilot Jim "Clue" Less took off from Edwards Air Force Base in California and landed successfully, reaching speeds of approximately Mach 1.1.

The flight commenced at 11:08 AM Pacific Time and lasted 81 minutes. During the test, experts evaluated the aircraft's flight characteristics in both subsonic and supersonic modes.

The X-59 aircraft is designed to operate at supersonic speeds with minimal sonic impact. Instead of the large sonic boom typically seen, it produces only a characteristic low noise.

During testing, the X-59 was escorted by a NASA F-15 to monitor the flight, and the F-15's sonic boom masked any potential acoustic effects from the X-59. It's worth remembering that this aircraft is scheduled to make its maiden flight in late October 2025.

The QueSST (Quiet Supersonic Technology) program aims to develop vehicles capable of significantly reducing noise levels during supersonic flight.

If successful, this would pave the way for the resumption of supersonic flights over land, currently restricted by international regulations due to the excessive noise from sonic booms.

The core idea behind the X-59 is the unique aerodynamic shape of its airframe, which allows for the minimization of shock wave formation and intensity.

One of the key design elements is the extremely long and pointed nose, which helps to create a gradual shock wave and reduce the force of the sonic boom.

Even the waves generated during flight must be significantly weaker than those from traditional supersonic aircraft.
