US Vows To Preserve Access To Space 

Richard Palmer, director of the Capability and Resource Integration Directorate at U.S. Space Command, said disclosing the capabilities was intended to deter adversaries, while also showing America’s readiness to respond.

“The acknowledgment of these space-control capabilities is fundamental to ensuring that we prevent deterrence from failing, and that we are postured and ready should deterrence fail to employ them effectively,” Palmer said Tuesday. “The bottom line is that our joint force and our allied forces require space. Our economies require space,” he added. “We are ready in the U.S. to preserve that.”

Space Force Lifts The Veil On Orbital Weapons 

Space Force chief Douglas Schiess separately confirmed on Tuesday that enlisted Guardians “operate on-orbit weapons that can defend the Joint Force against space-enabled attacks.” He said the service would make “disciplined and responsible choices” as it expands its orbital arsenal.

The comments followed Air Force Secretary Troy Meink’s announcement on Monday that the U.S. “has on-orbit space control weapons capable of defending the Joint Force against hostile adversary action.” Meink declined to identify the systems. “Talking about the details of what we’re doing would actually not benefit that deterrence,” he said.

Golden Dome Hardware Moves Closer To Orbit 

Meink separately said Golden Dome’s space-based interceptor program had advanced from an initial contract to “flight-ready hardware” in less than a year.

The Space Force awarded 20 prototype contracts worth up to a combined $3.2 billion to 12 companies in April, including SpaceX, Northrop Grumman, Lockheed Martin and Anduril. The program aims to demonstrate an integrated space-based interception capability by 2028.

The push comes as China develops spacecraft capable of grappling and moving satellites, while Russia has been linked to electronic interference and a potential nuclear anti-satellite capability.

“We’ve gone from not talking about counter-space capabilities ... to now saying flat-out we have weapons in space,” said Victoria Samson of the Secure World Foundation. “The pendulum keeps on shifting over that way.”

Which Space Stocks Stand To Benefit? 

SpaceX has the most exposure to Washington’s buildup. It received a $2.29 billion contract in May to build the secure Space Data Network Backbone and also a $4.16 billion award for satellites and supporting systems to track airborne threats from orbit. 

Rocket Lab holds a $266 million Space Force contract for 12 suborbital missile-defense launches, with options for six more, and two Space Data Network orders worth a combined $12 million. Its proposed $8 billion acquisition of Iridium Communications would add an established satellite network to its launch and spacecraft businesses.
