The Boeing-built X-37B spaceplane, currently 10 months into its seventh mission, is preparing to carry out a series of advanced aerobraking manoeuvres to enhance the United States Space Force’s (USSF) understanding of fuel-efficient orbital techniques, according to a press release from Boeing.
The Orbital Test Vehicle (OTV-7), which has been operating in a Highly Elliptical Orbit (HEO) since December 2023, will use Earth’s atmosphere to slow down and reduce its altitude with minimal fuel consumption.
This will be the first time Boeing, the USSF, and the X-37B have attempted such a demonstration, which aims to further space manoeuvring capabilities. “Space is a vast and unforgiving environment where testing technologies is critical to the success of future endeavours,” said Michelle Parker, vice president of Boeing’s Space Mission Systems. “There is no other space platform as capable, flexible, and manoeuvrable as the X-37B, and its next demonstration will be another proof point that this test vehicle sets the pace of innovation.”
The aerobraking process will see the X-37B utilising atmospheric drag to reduce its energy and alter its orbit while using minimal fuel.
The disposal of the Service Module will adhere to established space debris mitigation standards, ensuring the orbit change is conducted in a safe and responsible manner. Once the aerobraking manoeuvres are complete, the X-37B will resume its mission objectives focused on testing and experimentation.
General Chance Saltzman, Chief of Space Operations for the USSF, stressed the importance of this milestone, stating: “This first-of-a-kind manoeuvre from the X-37B is an incredibly important milestone for the United States Space Force as we seek to expand our aptitude and ability to perform in this challenging domain.”

I was reading up on this a while ago. Interesting bit of kit. Deployable equipment bay, for launching “stuff”, or just testing it in position, spare thruster housing aft, for testing new propulsion methods like the newer ion drives, etc.
That’s just the info they’re willing to publish…
The X-37B is now under the control of Space Force’s Delta 9 unit which is responsible for orbital warfare. It’s speculation, but informed speculation, that Space Force now sees the X-37B as a means to take out other nation’s satellites and anti-satellite capabilities.
TWZ has an in-depth look at the X-37B, which complements George’s article above.
