Forty years later, he is the Vice Chief of Space Operations, the number two officer in the United States Space Force. There was no plan. There was no map. There was a recruiter and a string of people who kept opening doors as he was ready to walk through them.
In this episode of the Spacepower Podcast, SFA Founder and host Bill Woolf sits down with Gen. Bratton, Vice Chief of Space Operations, to close out the season with the question every young person asks when they look at this service: is there a path for me?
The answer, as Gen. Bratton tells it, is that there are a hundred of them. He was an E-1. He was a staff sergeant in the Arizona Air National Guard fixing ground radars. He was a captain who walked into his commander's office and asked for a job earmarked for a lieutenant colonel. He flew high altitude balloons over the Nevada ranges. He volunteered for a deployment to Baghdad. He found out he was going to build STARCOM in a four car parking garage.
In this conversation, Gen. Bratton discusses:

Two American cities had land, airspace, and a hunch. Neither had a guarantee. This is the story of what it actually took to turn that hunch into reality, and a bet that's still being placed.
The commercial and national-security space economy has outgrown its old coastal footprint, and the launch, testing, and infrastructure demand it's generating has nowhere left to go but inland. That shift is landing in city halls that never expected to be part of the space conversation, and the mayors making the call are becoming the model for how it gets done.
In this episode of the Spacepower Podcast, SFA Founder and host Bill Woolf sits down with Mayor Lori Blong of Midland, Texas, and Mayor Douglas Nicholls of Yuma, Arizona, to unpack what it actually took to turn two very different cities into space and defense hubs, and why the decision came down to local leadership, not geography.
Space development isn't happening to these cities from the outside anymore, it's being decided by them. Midland and Yuma make the case that a city's place in the space economy has less to do with geography and more to do with whether its leadership will hold a bet through the years before it pays off.

Nobody handed them the answers. When Chance Saltzman got engaged, two weeks before shipping out for missile training, neither he nor Jennifer knew what military life would demand. When he chased a brand-new weapons school, the personnel office told him it was "a terrible idea, an unproven path." So he did it. The through-line of a 35-year career and marriage turned out to be four words: we'll figure it out.
That instinct built more than a family. It helped build a service. The Space Force is still writing its identity, what it means to be a Guardian, what traditions to keep, what culture to forge from scratch, and few people have shaped that answer more directly than its Chief of Space Operations. This is the story of the character behind the stars.
In this episode of the Spacepower Podcast, SFA Founder and host Bill Woolf sits down with General Chance Saltzman, Chief of Space Operations, and Jennifer Saltzman, back in the Space House where Bill first interviewed a brand-new CSO four years earlier, for a candid conversation about marriage, character, and how you build something that lasts without a blueprint.
In this episode:
- Why "an unproven path" was the exact reason Saltzman chose the Weapons School, and how a warning to stay away became the best career advice he ever ignored
- How a physics scholarship he couldn't finish funneled him into ICBM operations, and why he was certain he'd gotten the better end of the deal
- What it actually means that Guardians conduct combat operations from garrison, watch an adversary act in space, then drive home for soccer practice and help with math homework
- The 2007 Chinese anti-satellite test, told from the ops floor, and the moment there was no hand signal for "they destroyed the satellite"
- How the "floodgates" from missiles to space turned a generation of missileers into the Space Force's first operators
- The surreal night a Hollywood director had dinner at their house, and what saying "yes" has to do with a whole career
Standing up a service from nothing: no flag, no song, no uniform, and why "you have to pay the tax" of becoming real
- Guardian #89, the 89th Weapons School space graduate, Bowling Green High class of '89 — and why Saltzman calls it karma
- Saltzman's one regret as CSO
- Why Jennifer is his "best sensor", the things Guardians will tell her that they'll never tell the CSO
How a marriage that "grew up together" with the service became a lesson in connection and community
The Space Force will be defined by its technology and its doctrine. But this conversation is a reminder that services are built by people, and that identity, partnership, and the willingness to walk a path no one has mapped are as foundational as any capability in orbit.

There is a version of ready where the hardware works. There is another version where the people, the doctrine, the joint playbooks, and the partner relationships all hold under the pressure of an actual conflict. Building the second one is a full-time job, and almost none of it is visible from the outside.
The Space Force organizes, trains, and equips. U.S. Space Command employs. The layer in between, the exercises, the wargames, the training architecture, and the doctrine that tells the joint forceMaj. Gen. "Bull" Keener: Inside Space Command's Exercise and Wargaming Architecturehow to operate together in a contested domain, belongs to the J7. As adversary counterspace capability moves from projection to fielded reality, that layer is where readiness is either proven or exposed.
In this episode of the Spacepower Podcast, SFA Founder and host Bill Woolf sits down with Maj. Gen. Samuel "Bull" Keener, Director of Exercises, Training, Wargames, and Experimentation (J7) at U.S. Space Command, to walk through how a combatant command builds itself into a warfighting organization.
Capability delivered is not capability employed. The distance between the two is measured in exercises, in wargames, and in the honesty of the models you train against. That distance is the J7's work, and it is where the Space Force's investment either becomes joint warfighting readiness or does not.
Editor's note: this conversation was recorded several months before U.S. Space Command published the Space Warfighting Environment 2040 on July 28, 2026.

Earlier this year, a finished GPS satellite was sitting in Florida ready to fly. The rocket assigned to it needed more time. The warfighters waiting on that satellite could not.
So System Delta 80 moved it. Different rocket. Full recertification. On orbit in about six weeks. What normally takes two years happened in a month and a half, and it was the fourth time the team had pulled off something like it.
Nothing in national security space gets off the ground without System Delta 80. Every satellite this series has covered, the SATCOM links, the GPS constellation, the systems certified by OTTI, all of it begins at the launch pad. This episode is the capstone: how the Space Force gets its most critical capabilities to orbit, what it takes to keep multiple launch providers viable, and what becomes possible when satellites are no longer constrained by the fuel they launched with.
In this episode of the Spacepower Podcast, SFA Founder and host Bill Woolf sits down with Col. Ryan Hiserote, Commander of System Delta 80 at Space Systems Command, to discuss the National Security Space Launch program, the GPS rocket swap that made headlines, and the on-orbit servicing mission that could fundamentally change how the Space Force operates in space.
In this conversation, Col. Hiserote discusses:
- Why System Delta 80's claim — that nothing in national security space gets off the ground without it — is literal, not rhetorical
- How the dual-lane NSSL structure works: Lane 1 for competition and capacity, Lane 2 for no-fail missions with complex requirements
- What it actually takes to certify a new rocket for national security missions — and why that process takes years
- How the GPS 3-8 rocket swap worked, why it happened, and what it signals about the Space Force's willingness to move at the speed of need
- Why Rocket Lab and Stoke Space were added as Lane 1 providers in early 2025 — and what the service is looking for as it evaluates more
- The on-orbit servicing mission: what Starfish Space's Otter vehicle and Astroscale's refueling demo are designed to prove
- Why Gen. Whiting at U.S. Space Command has been calling for a maneuver warfare strategy in space — and how on-orbit refueling enables it
- What it means for a satellite to be "no longer constrained by its gas tank" — and how that changes tactics
- Why Col. Hiserote describes launch as a team sport — and who all the players are
- Why he calls this the most exciting time to be in the launch business since the Apollo days
The Space Force can build the most advanced satellites in the world. They mean nothing until they reach orbit. This is the mission that starts everything else — and it's about to get a lot more capable.

Fighter pilots don't go to war on day one. First comes Red Flag, the punishing mock combat over the Nevada desert designed to be harder than anything a pilot will ever face in actual conflict, so that when the real moment comes, it isn't the first time.
For most of the space mission's history, that rehearsal didn't exist. Guardians operated systems that had only ever been tested in benign environments. The capabilities were real. The training wasn't. System Delta 81 is the unit changing that.
In this episode of the Spacepower Podcast, SFA Founder and host Bill Woolf sits down with Col. Corey Klopstein, Commander of System Delta 81 at Space Systems Command, to discuss the Operational Test and Training Infrastructure, OTTI, the Space Force's answer to Red Flag, and why building it is one of the most consequential things SSC is doing right now.
In this conversation, Col. Klopstein discusses:
- Why the Space Force went this long without a Red Flag equivalent, and what changed in the threat environment to make OTTI urgent
- The three layers of space test and training infrastructure: digital simulation, physical on-orbit assets, and the data architecture connecting them
- Why a simulation is only as honest as the live data feeding it, and what it takes to build a physical lane that validates the digital one
- What a range-as-a-service contract looks like in practice, and how a commercial satellite's on-orbit maneuver became a live Guardian training event
- Why SYD 81 pairs with multiple commands simultaneously, Space Training and Readiness Command and Combat Forces Command, rather than a single Mission Delta
- How the Joint Simulation Environment, already used by F-35 pilots, is being extended for space
- What Gen. Saltzman told Col. Klopstein about delivering an F-22 without a training infrastructure, and why that analogy captures exactly what OTTI solves
- Why "when I say football and you say football, we need to mean the same thing", and what that has to do with building a shared operational language across commands and allies
- What ruthless prioritization looks like for a mission area with more requirements than people and more requirements than money
You can build the most advanced satellite in the world. If the Guardian operating it has never trained against a thinking adversary, you haven't delivered combat power. This episode is about the infrastructure that closes that gap, before the conflict starts.

Your phone knows where you are right now. Your bank recorded the exact millisecond of your last transaction. The plane you flew on landed safely in low visibility. The farmer who grew your food planted rows one to two centimeters apart. Every one of those things runs on a signal broadcast from twelve thousand miles overhead, a signal the United States Space Force has guaranteed to the entire world, by law, since way before its inception, 1978.
GPS is the closest thing the planet has to a shared utility. It is also something the Space Force has to defend, every single day, against adversaries who cannot out-engineer it and are actively trying to deny it.
In this episode of the Spacepower Podcast, SFA Founder and host Bill Woolf sits down with Col. Neil Barnas, Commander of System Delta 831 at Space Systems Command, to discuss what makes American GPS the global gold standard, what it takes to keep a 31-satellite constellation running against active threats, and what the next generation of GPS will be able to do that the current one cannot.
In this conversation, Col. Barnas discusses:
- The three pillars that make American GPS the global gold standard, accuracy, transparency, and a legally guaranteed service level
- Why GPS is certified for human flight operations, and what that standard means in practice
- How the signal has been continuously broadcast since 1978, and why the satellites being launched today are designed to serve for 15 years or more
- What GPS Space Vehicle 10, the final GPS III satellite, means for the constellation and the warfighters waiting on it
- The GPS III-F upgrade: a 1,200-kilometer spot beam capable of up to 63 times the baseline M-code signal power, focused on exactly the area of the Earth where it's needed most
- How 63 international partners integrate GPS user equipment into their own aircraft, ground vehicles, and munitions
- Why agriculture is one of the most GPS-dependent industries on Earth, and what differential GPS does at the centimeter level
- How AI tools are now processing eleven hundred pages of technical documentation to accelerate acquisition decisions
- What the System Delta construct means for a mission area as globally consequential as position, navigation, and timing
GPS is often called a gold standard. This episode explains what that standard actually requires to maintain, and what happens to the joint force if it degrades.

On the worst day imaginable, the day a nuclear decision has to be made, the President of the United States needs to talk to commanders and allies anywhere on Earth. That conversation runs through space. And the people responsible for delivering it just did so two full years ahead of schedule.
But this episode isn't just about a single acquisition win. It's about a fundamental shift in how the Space Force thinks about buying capabilities. For decades, a cultural wall separated the people who acquired systems from the people who fought with them. Requirements passed over a fence. Timelines drifted. By the time a capability arrived, the threat had sometimes already moved. System Delta 88 exists to make that model obsolete.
In this episode of the Spacepower Podcast, SFA Founder and host Bill Woolf sits down with Col. A.J. Ashby, Commander of System Delta 88 at Space Systems Command, to discuss how the Space Force is rewiring military satellite communications acquisition and what it looks like when acquisition becomes a warfighting function.
In this conversation, Col. Ashby discusses:
Military satellite communications is invisible on a good day. It has to be invisible, reliable, and unjammable on the worst one. This episode is about the team building it and the reform changing how the Space Force buys for war.

Ten thousand Guardians. That's it. The entire United States Space Force fits inside a mid-sized college campus. And yet the domain they protect underpins every GPS route, every weather forecast, every financial transaction, every call you made today.
Jennifer Saltzman has been part of that community since before the Space Force existed, since before most people had heard the word "Guardian," since the uniforms were still being designed and the swag hadn't been invented yet. As the spouse of Gen. B. Chance Saltzman, Chief of Space Operations, she has traveled to bases and installations across the country and around the world, meeting families in places where a handful of Guardians are embedded in a much larger military community, sometimes feeling invisible, always doing critical work.
