U.S. President Trump’s “One, Massive Stunning Invoice Act,” H.R. 1 consists of $1 billion for the U.S. House Drive (USSF) X-37B navy spacecraft program.
The largely categorized X-37B – additionally known as the Orbital Take a look at Automobile (OTV) program – carried out its seventh mission, touchdown at Vandenberg Air Drive Base in California on March 7, touching down after 434 days in orbit.
As for the way that $1 billion can be spent, and when the subsequent X-37B would depart, House.com reached out to the area aircraft’s builder, Boeing. We obtained a “thanks for the question” in response, and an inquiry-altering observe to contact the Air Drive for touch upon the X-37 schedule and funds.
House check platform
“The united states X-37B program helps expertise danger discount, experimentation, and operational idea improvement for future re-usable area autos,” responded USAF Colonel Lori Astroth, Public Affairs Deputy Director for House throughout the Secretary of the Air Drive Workplace of Public Affairs on the Pentagon.
The X-37B program “serves as a versatile area check platform to conduct varied experiments that may be transported to area and returned to Earth,” Col. Astroth added. “Additional info concerning X-37B’s value and funds info will not be releasable.”
Extremely elliptical orbit
That final hush-hush flight of the X-37B Orbital Take a look at Automobile-7 (OTV-7) featured the craft being hurled right into a extremely elliptical excessive Earth orbit by way of a Falcon Heavy rocket again on December 28, 2023.

After aerobraking to a low Earth orbit and finishing its check and experimentation goals, the area aircraft efficiently carried out its deorbit and touchdown procedures.
As did the earlier (OTV-6) area aircraft trek, OTV-7 additionally concerned a service module that expanded the capabilities of the spacecraft.
“The profitable completion of the novel aerobraking maneuver demonstrated the agile and versatile capabilities the X-37B supplies the USA House Drive,” based on the assertion issued by the Secretary of the Air Drive Public Affairs.
The aerobraking method entails use of atmospheric drag over the course of a number of passes to vary orbits whereas expending minimal gasoline.
“Whereas on orbit, Mission 7 achieved a spread of check and experimentation goals supposed to exhibit the X-37B’s strong maneuver functionality whereas serving to characterize the area area by means of the testing of area area consciousness expertise experiments,” the assertion notes.
Flight roster
This is a list of earlier flights of the area aircraft:
- OTV-1: launched on April 22, 2010 and landed on December 3, 2010, spending over 224 days on orbit.
- OTV-2: launched on March 5, 2011 and landed on June 16, 2012, spending over 468 days on orbit.
- OTV-3: launched on December 11, 2012 and landed on October 17, 2014, spending over 674 days on-orbit.
- OTV-4: launched on Might 20, 2015 and landed on Might 7, 2015, spending almost 718 days on-orbit.
- OTV-5: launched on September 7, 2017 and landed on October 27, 2019, spending almost 780 days on-orbit.
- OTV-6: launched on Might 17, 2020 and landed on November 12, 2022, circling Earth for 908 days.
- OTV-7: lofted on December 28, 2023 and touched down on March 7, 2025, circling Earth for 434 days.
First use applied sciences
The builder of the automobile, Boeing, has beforehand famous that the X-37B makes use of a number of “first use in area” applied sciences together with:
- Avionics designed to automate all de-orbit and touchdown capabilities.
- Flight controls and brakes utilizing all electro-mechanical actuation; no hydraulics on board.
- Use of a lighter composite construction, somewhat than conventional aluminum.
- New technology high-temperature wing modern tiles and toughened uni-piece fibrous refractory oxidation-resistant ceramic (TUFROC) tiles and superior conformal reusable insulation (CRI) blankets.
In keeping with Aviation Week & House Know-how, the House Drive is using the X-37B system as an on-orbit testbed to check out new applied sciences, to raised perceive related adversarial platforms and to design new coaching environments, citing feedback to the publication in January by Chief of House Operations Normal Probability Saltzman.
