A war fought in orbit will not stay between the two countries that start it. That was the blunt message Gen. Chance Saltzman carried into his final public address as Chief of Space Operations, delivered to an international audience of military leaders at the Global Air & Space Chiefs’ Conference in London. Orbital conflict, the outgoing Space Force chief argued, is no longer hypothetical, and deterrence flows from combat-credible forces rather than declarations.
The speech capped a military career spanning more than three decades and a tenure leading a service that barely existed when he took command.
The core warning
Saltzman’s central claim was geographic as much as strategic. Satellites do not respect borders. A war fought in orbit — even one initiated between two adversaries — sweeps in every nation with assets overhead.
He told the London audience that orbital mechanics will place every nation’s space capabilities in a space war zone whether those nations want to be there or not. Because the consequences will be shared, he argued, responsibility for a safe, secure, and stable space domain should be shared as well.
The message was aimed squarely at allied air and space chiefs. Saltzman framed space as a team sport — not by preference, but by physics.
Deterrence as capability, not signaling
Saltzman has spent his tenure pushing back against a version of deterrence built primarily on statements, red lines, and calculations about adversary intent. His alternative strategy asks the service to avoid operational surprise, deny adversaries the benefit of striking first, and develop counterspace capabilities that do not generate long-lived orbital debris.
The logic is that visible, credible force does the deterrent work on its own.
Saltzman argued that combat-credible capabilities should create a deterrent effect, and that if they don’t, the force will be prepared to respond to aggression.
That framing matters because it shifts the burden of prediction. Rather than trying to game out what Beijing or Moscow might do, the Space Force builds forces designed to defeat what those adversaries have already fielded — jammers, dazzlers, co-orbital interceptors, and cyber tools capable of disabling satellites.
Those warnings are grounded in a specific assessment: China and Russia are developing systems capable of jamming, disabling, or destroying satellites. That has pushed the Space Force’s focus toward what is known as space control — the ability to defend friendly assets and, if necessary, disrupt adversary space operations.
The terrestrial precedent is already visible. Widespread GPS jamming across the Middle East during recent conflicts has disrupted commercial aviation, shipping, and civilian navigation across a wide region. Space-based services are already contested infrastructure. The question is whether the platforms themselves become targets.
Saltzman’s answer is that if adversaries believe an attack on U.S. satellites can be answered — and answered without turning low Earth orbit into a debris field — the attack becomes less likely.
A service transformed in four years
When Saltzman took command, the Space Force was less than three years old. It had a thin institutional identity and no coherent long-term force design.
By the time of his farewell, the service had grown and gained visibility through its role supporting recent operations.
Under Saltzman, the Space Force introduced the Objective Force — a 15-year force-design effort meant to define the spacecraft, personnel, infrastructure, and partnerships the service will need through 2040. It also began implementing a new personnel model that blends full- and part-time service, moving away from the traditional active-reserve split. In April, nearly 250 Air Force reservists were selected to transfer into part-time Guardian roles, a step toward a single, unified component.
The budget shadow
Saltzman’s farewell came as House lawmakers signaled they would approve only a fraction of the funds the Trump administration had requested for major space programs through budget reconciliation.
The White House had requested substantial funding through the normal defense budget plus additional funding through reconciliation — a partisan-controlled maneuver rarely used for defense spending until recently. The reconciliation package was meant to fund programs including space capabilities and missile defense efforts. House leaders indicated they would back a significantly smaller reconciliation bill.
Saltzman declined to say publicly whether that shortfall would harm the service. He said he stood behind the request and called it a dramatic increase in resourcing for capabilities he considers vital. The rest, he acknowledged, is a negotiation between the executive and the legislature.
Alliances and the political weather
The London speech came after recent tensions between the United States and European allies. Saltzman’s message pushed the other direction.
He emphasized that nations are stronger as a team than individually, pointing to decades of evidence supporting that conclusion.
He also offered a rare piece of advice to uniformed leaders operating in politically turbulent times, describing military institutions in democracies as providing stability — the weight that slows movement but keeps the vessel stable in a storm.
The framing is worth pausing on. Space is one of the few remaining domains where allied cooperation is not just useful but structurally required. Satellites cross national airspace hundreds of times a day. Space situational awareness depends on ground stations scattered across friendly territory. Debris from a single kinetic anti-satellite test can threaten spacecraft belonging to dozens of nations. The physics forces the politics.
What Saltzman leaves behind
Lt. Gen. Douglas Schiess is expected to become the third Chief of Space Operations if confirmed by the Senate. He inherits a service with a clearer doctrine than the one Saltzman received, but also with sharper political headwinds, a contested budget, and adversaries whose counterspace programs have matured considerably in recent years.
One line from Saltzman’s farewell hints at how he thinks about the job he’s handing off: not all challenges must be solved, and some should simply be managed.
Acquisition speed, interoperability across allied systems, information sharing between classified and unclassified networks — these are persistent conditions of running a modern military service, not problems with endpoints. Treating them as solvable invites frustration. Treating them as manageable invites patience.
That’s a quieter argument than the headline warning about war in orbit, but it may be the more consequential one for the institution Saltzman built. The Space Force he leaves is younger than most of its guardians’ careers. It will spend the next decade discovering which of its problems are the kind that get fixed and which are the kind that get lived with.
For readers thinking about how space reshapes institutional identity and civilian imagination, our earlier piece on Artemis 2, Apollo 8, and overview thinking traces a parallel question from the exploration side of the ledger.
