This overhead view of the X-59 shows the aircraft’s current state of assembly at Lockheed Martin Skunk Works in Palmdale, California. Throughout the manufacturing process, the team often removes components to effectively and safely assemble other sections of the aircraft. The X-59’s horizontal tails and lower empennage were recently removed from the aircraft and can be seen behind it as the team prepares for the installation of the engine. The X-59 is the centerpiece of the Quesst mission which plans to help enable commercial supersonic air travel over land.

Following the successful installation of mounting brackets, technicians successfully installed the pallet for the eXternal Visibility System, or XVS, onto the X-59 Quiet SuperSonic Technology X-plane, also known as X-59 QueSST. The pallet installation marks an assembly milestone as the first NASA flight systems hardware to be installed onto the vehicle. X-59 will fly to demonstrate the ability to produce quiet thumps at supersonic speeds, instead of the typical, loud sonic booms associated with supersonic flight.

Here is a closer view of the X-59 fuselage section of the aircraft during assembly. The fuselage contains the cockpit and helps define the distinct shape of the X-59. Lockheed Martin Photography By Garry Tice 1011 Lockheed Way, Palmdale, Ca. 93599 Event: SEG 210 Forebody-Subsystems Date: 5/12/2021

The team at Lockheed Martin Skunk Works in Palmdale, California, merged the major sections of the X-59 Quiet SuperSonic Technology aircraft, which includes the wing, tail assembly, and fuselage or forward section. This marks the first time the X-59 resembles an actual aircraft. (Pictured here is a overhead view of the X-59 as it comes together for the major assembly merger in summer 2021.)

An overhead view of the X-59 during assembly in spring 2023. Assembly took place at Lockheed Martin’s Skunk Works facility in Palmdale, California. Once complete, the X-59 is designed to fly supersonic while reducing the loud sonic boom. The Quesst mission could help change the rules for commercial supersonic air travel over land.

This is an up-close view of the X-59’s engine inlet – fresh after being painted. The 13-foot F414-GE-100 engine will be placed inside the inlet bringing the X-59 aircraft one step closer to completion. Once fully assembled, the X-59 aircraft will begin flight operations, working toward demonstration of the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump, helping to enable commercial supersonic air travel over land.

The upper empennage, or tail section of the plane, and engine bay is surrounded by a blue gantry that is used to assist with ground installation and removal of the X-59’s lower empennage and engine. Once fully assembled, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land. This aircraft is the centerpiece of NASA’s Quesst mission.

S94-30393 (23 Nov 1993) --- In the south level IV stand of the Operations and Checkout Building low bay, the Space Radar Laboratory -1 (SRL-1) antenna is being placed atop a pallet which holds the antenna electronics. SRL-1 is scheduled to fly on Space Shuttle mission STS-59 next year. It is comprised of two different imaging radars, the Spaceborne Imaging Radar-C (SIR-C) and the X-band Synthetic Aperture Radar (X-SAR). These radars are the most advanced of their kind to fly in space to date, and will allow scientists to make highly detailed studies of the Earth's surface on a global scale. An Interface Verification Test of the antenna and a Mission Sequence Test will be performed on the fully assembled SRL-1 later this month.

A Lockheed Martin Skunk Works technician inspects some of the wiring and sensors on the X-59 aircraft in preparation for the first power-on system checkouts. Once complete, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land. This aircraft is the centerpiece of NASA’s Quesst mission.

Here is an image of the X-59’s 13-foot General Electric F414 engine as the team prepares for a fit check. Making sure components, like the aircraft’s hydraulic lines, which help control functions like brakes or landing gear, and wiring of the engine, fit properly is essential to the aircraft’s safety. Once complete, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land.

This is an image of the X-59 inlet with a safety covering. The inlet’s purpose is to adjust air speeds before they pass through the aircraft’s engine. The purpose of the covering is to protect the inlet and engine from foreign objects.

The X-59’s nose is 38-feet long – approximately one third of the length of the entire aircraft. The aircraft, under construction at Lockheed Martin Skunk Works in Palmdale, California, will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump.
