EL SEGUNDO, Calif. -- In April 2025, a massive U.S. Air Force C-17 Globemaster III descended onto the flight line at Buckley Space Force Base in Colorado, tasked with a critical national security mission: to secure and transport the eighth next-generation Global Positioning System satellite, the multimillion-dollar GPS III Space Vehicle 08, or SV-08.
For the two men overseeing the transport, the moment was both a professional and personal milestone.
Up in the cockpit was Air Force Capt. Sebastian Bedoya, the C-17 aircraft commander. Down on the tarmac, waiting with SV-08 to be loaded, was his older brother, Space Force Maj. Esteban Bedoya.
While teamwork and cutting-edge technology development brought the GPS II satellite to the tarmac, it was a lifetime of mutual mentorship, shared sacrifice, and a relentless climb from the enlisted ranks that brought the brothers face-to-face that day.
Originally from Colombia, the Bedoya family moved to the United States when the brothers were children. After a brief period living in Costa Rica — where an uncle with prior U.S. military experience planted the seed of service — the brothers returned to the U.S. with a shared mission to give back to their adopted country.
Older brother Esteban enlisted in the Air Force first. He was 17. From that point on, he served as the trailblazer for his younger brother, always staying a few steps ahead and charting a course for Sebastian to follow. Two and a half years later, Sebastian enlisted as a materiel management specialist, eager to mirror the older brother he deeply admired.
"My brother mentored me and told me what to do and how to stand out and work hard," Sebastian said. "He just said, 'Keep your focus, get your school done, get your career progressed as much as you can.' And that's what I did."
As Esteban progressed through the enlisted ranks to become a technical sergeant, he realized that earning a degree and commissioning as an officer was the best path forward. He earned his bachelor's and master's degrees, paving the way to Officer Training School. True to form, he immediately turned around to help pull his brother up the exact same ladder.
Knowing Sebastian harbored a lifelong dream of flying, Esteban actively researched the pathways to the cockpit. He discovered that the operations route at OTS actually had higher acceptance rates than general support roles. Esteban guided his younger brother through the rigorous application and testing process, ensuring Sebastian was perfectly positioned for success.
"I helped him through that package, and we both decided to commission," Esteban said, a subtle point of pride in his younger brother's eventual success.
Sebastian earned his wings, eventually becoming an instructor pilot for the C-17 with the 3rd Airlift Squadron at Dover Air Force Base in Delaware, while Esteban transitioned into missile operations and eventually space acquisitions, landing a pivotal role as the deputy program manager for the GPS III program in Detachment 1, under Combat Forces Command’s Mission Delta 31.
In this capacity, Esteban’s contributions were critical to the integration of next-generation GPS. Working closely with Space Systems Command’s System Delta 831, he was deeply involved in the development and technical oversight of the GPS III series. His work within System Delta 831 ensured that the satellite’s advanced payloads, including the more secure Military Code (M-code) signal, met the rigorous performance requirements necessary for global military operations.
The brothers’ professional paths converged in early 2025 when the Space Force and Air Force were tasked with executing the GPS III SV-08 launch on a radically accelerated timeline, cutting the typical 24-month launch preparation down to just three months.
Recognizing that C-17s were required to transport SV-08 to Florida, Esteban initiated a request to see if Dover Air Force Base could support the mission. Sebastian worked the logistics from his end, navigating a busy deployment schedule to ensure he was assigned to pilot the specific aircraft carrying his brother's satellite payload.
Before the flight, Esteban arranged for his younger brother to tour the Lockheed Martin facility to see the technology they were about to move. The GPS III series is the third generation of the U.S. Space Force’s GPS satellites and consists of ten 5,000-pound satellites manufactured by Lockheed Martin, with the first launched in 2018.
"We couldn’t actually see what the satellite looked like once it was packaged for air transport," Sebastian said. "But they showed us the exact same model. You think about it—that’s going to be put in a spaceship and go up into space. And to think that GPS is something that we as pilots use every day. Being able to be a part of that whole chain of events was great."
Loading the massive satellite onto the C-17 was a meticulous, five-hour ballet requiring inches of clearance. After it was secured, Esteban rode in the back with his payload, entrusting his life and his multimillion-dollar mission to the younger brother he had once guided through high school and basic training.
"Flying into Cape Canaveral at nighttime with a million-dollar asset and my brother watching me and judging me—it was a great feeling once we touched down safe and sound," Sebastian joked. "We taxied to park and were like, 'Hey, we’re halfway there. Now put that in a spaceship!'"
The GPS III satellites they helped deploy represent a massive leap in capability. GPS III satellites are the first to broadcast Military Code (M-code), the military’s encrypted GPS signal designed to provide more secure, jam-resistant signals. The cutting-edge technology was built on the dedication of joint force personnel.
For the Bedoya brothers, that culture of collaboration runs deeper than the uniform. It is a lifelong bond—one of guidance, profound respect, and brotherly love—crystallized on a tarmac, contributing to a constellation that will guide the world for decades to come.
“It’s an incredible feeling because when you’re a kid, you always do everything with your brother," Esteban recalled of that day on the flight line. "You’re playing games, playing sports, fighting—and then you get to do that when you grow up with big boy toys. Definitely the best moment of my professional career, for sure."
