✈️The Lockheed Martin X-59 Quesst ("Quiet SuperSonic Technology"), sometimes styled QueSST, is an American experimental supersonic aircraft under development by Skunk Works for NASA's Low-Boom Flight Demonstrator project. Preliminary design started in February 2016, with the X-59 originally planned to begin flight testing in 2021. After repeated delays, it began flight testing in late October 2025.

☝️In February 2016, Lockheed Martin was awarded a preliminary design contract, aiming to begin flights in the 2020 timeframe. A 9%-scale model was to be wind tunnel tested from Mach 0.3 to Mach 1.6 between February and April 2017. The preliminary design review was planned to be completed by June 2017. While NASA received three inquiries for its August 2017 request for proposals, Lockheed was the sole bidder.

🚀It is expected to cruise at Mach 1.42 (1,510 km/h; 937 mph) at an altitude of 55,000 ft (16,800 m). It is designed to create only a low 75 effective perceived noise level (EPNdB) thump in order to re-evaluate the viability of supersonic transport, since one of the main reasons previous supersonic transports (e.g. Concorde) were retired was due to their extremely loud supersonic booms.


⚙️NASA and Lockheed Martin Skunk Works are using smart aerodynamics to reshape how sound travels at supersonic speed.
The main wing’s curved design spreads pressure waves, while canards fine-tune the trim.
A conventional tail gives the jet better stability than the earlier V-tail designs.
The result: a supersonic jet that glides through the air at Mach 1.4, but with the quiet footprint of a car door slam.

🤓The X-59's long, slender shape prevents the shock waves from merging, turning a loud sonic boom into a quiet "thump". By carefully shaping the aircraft's volume and lift distribution, the design spreads the shock waves so they don't coalesce into a single, strong front and rear shock that creates a loud "N-wave". Instead, the individual pressure waves remain separate, resulting in a much softer sound on the ground.

🔥Yes, a key design feature of the X-59 is its smooth underside, which is crucial for achieving its "quiet" supersonic flight objective.
The aircraft's unique shape is specifically designed to prevent shockwaves from merging to create a loud sonic boom. Instead, the design spreads out the shockwaves, resulting in a much quieter "sonic thump" or soft sound.


🧐“How is the X-59 so quiet?”

🤐Because it doesn't talk a lot 🤫

🤔The secret is its shape.
That super-long nose stretches the airflow so the first shockwave forms gently.
The canards, wings, and tails (T-tail + conventional) each make their own small waves — spaced out and stretched on purpose.
Normally, all those waves merge into one big boom that hits the ground as an ear shattering boom.
But on the X-59, the smooth belly and carefully balanced lift keep the waves separate, so they reach the ground as a quiet sonic thump instead of boom.
