The X-59 team at Lockheed Martin Skunk Works in Palmdale, California, load the lower empennage - the tail section - into place. The surfaces used to control the tilt of the airplane are called stabilators and are connected to the lower empennage. The X-59 is the centerpiece of NASA’s Quesst mission, which could help enable commercial supersonic air travel over land.

NASA’s X-59 sits in support framing while undergoing the installation of its lower empennage, or tail section, at Lockheed Martin Skunk Works in Palmdale, California in late March.

The tail of NASA’s X-59 aircraft is shown here in late March at Lockheed Martin Skunk Works in Palmdale, California where the plane recently underwent a final install of the lower empennage or better known as tail section of the plane.

Event: SEG 510 Upper Empennage An inside peek at the X-59 gives us a view from the aft end looking at the engine bay. Later in the assembly process, the engine will be placed inside this section. 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.

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.

Technicians work with a laser measuring system on the X-59 spine. The X-59 Quiet SuperSonic Technology, or QueSST, aircraft is under construction at Lockheed Martin Skunk Works in Palmdale, California, and will fly to demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump.

Here is a close-up of the GE F414 engine, from the aft deck or rear, before the tail section of the X-59 is lifted into place and attached to the aircraft. The aft deck helps control the shockwaves at the end of the aircraft and reduce the noise of a sonic boom to more of a sonic thump.

This image shows the X-59 aircraft’s lower empennage structure, or tail section of the plane, that was installed. The stabilators, the outer surfaces also seen in the photo, attach to the lower empennage and are used to help regulate the aircraft pitch which controls the up and down movement of the motion of the plane. The 13-foot engine will pack 22,000 pounds of propulsion and energy and power the X-plane to its planned cruising speed of Mach 1.4. 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 overhead view of the X-59 aircraft (left) prior to the installation of the General Electric F414 engine (center, located under the blue cover). After the engine is installed, the lower empennage (right), the last remaining major aircraft component, will be installed in preparation for integrated system checkouts. The X-59 is the centerpiece of the Quesst mission which plans to help enable commercial supersonic air travel over land.

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.

This overhead shot of the X-59 Quiet SuperSonic Technology or QueSST aircraft shows the assembly progress of the vehicle during Spring 2021. The aircraft, under construction at Lockheed Martin Skunk Works in Palmdale, California, will fly to demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump.

A laser scans the inside of the X-59 aircraft’s lower engine bay at Lockheed Martin Skunk Works in Palmdale, California. These scans can help identify potential hardware or wiring interferences prior to the final installation of the engine and lower tail.

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.

Event: SEG 570 Vertical Tail Assembly - Final Install Lockheed Martin technicians work on a fit check and installation of the vertical tail onto the X-59 aircraft. The plane is under construction at Lockheed Martin Skunk Works in Palmdale, California, will fly to demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump.
