Spacepower Podcast is the podcast from the Space Force Association exploring the leaders, ideas, and operations shaping the space domain. Hosted by SFA Founder Bill “Hippie” Woolf, the show features conversations with senior military leaders, policymakers, and industry experts on deterrence, maneuver, technology, and the evolving role of space in national security. Episodes include in-depth interviews and solo analysis breaking down the trends defining the future of spacepower.

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.

Guest:

Col. Corey Klopstein, Commander, System Delta 81, Space Systems Command

Col. Klopstein commands System Delta 81, the Space Systems Command unit responsible for developing and delivering the Operational Test and Training Infrastructure for the Space Force. On his 13th year at Los Angeles Air Force Base, he serves as both the SYD 81 commander and the Portfolio Acquisition Executive and Program Acquisition Executive for infrastructure. SYD 81 works across Space Training and Readiness Command and Combat Forces Command to ensure delivered capabilities are tested against real threats and Guardians are trained to operate them before the first flag event.

The Space Force's Invisible Battlefield: Why Test and Training Infrastructure Changes Everything

What Is The Space Force?

Just as the Navy maintains freedom of the seas, the Space Force maintains freedom of space for U.S. activities, both governmental and commercial.

Check out the Space Force 101 publication to learn all about this branch of the U.S. military.

In December 2024, the U.S. Space Force celebrated five years of growth, overcoming challenges while achieving significant milestones. This chronology captures the dedication and vision of the service’s founding members—ensuring future Guardians understand the monumental effort behind building the Space Force and the spirit that drives it forward.
