“All of the pieces that are required to make it viable exist. They’re out there,” Cinnamon told Ars. “We have satellites, we have boosters, we have seekers, we have fire control, we have IFTUs (in-flight target updates), we have inter-satellite links. The key is, all those pieces need to talk to each other and actually come together, and that integration is really, really difficult. The second key is, in order for it to be viable, you need enough of them in space to actually have the impact that you need.”
This frame from an Apex animation shows a space-based interceptor deploying from an Orbital Magazine.
Apex says its Project Shadow demo is scheduled to launch in June 2026. Once in orbit, the Project Shadow spacecraft will deploy two interceptors, each firing a high-thrust solid rocket motor from a third-party supplier. “The Orbital Magazine will prove its ability to environmentally control the interceptors, issue a fire control command, and close an in-space cross-link to send real-time updates post-deployment,” Apex said in a statement.
The Orbital Magazine on Apex’s drawing board could eventually carry more than 11,000 pounds (5,000 kilograms) of interceptor payload, the company said. “Orbital Magazines host one or many interceptors, allowing thousands of SBIs to be staged in orbit.”
Apex is spending about $15 million of its own money on Project Shadow. Cinnamon said Apex is working with other companies on “key parts of the interceptor and mission analysis” for Project Shadow, but he wasn’t ready to identify them yet. One possible propulsion supplier is Anduril Industries, the weapons company started by Oculus founder Palmer Luckey in 2017. Apex and Anduril have worked together before.
“What we’re very good at is high-rate manufacturing and piecing it together,” Cinnamon said. “We have suppliers for everything else.”
Apex is the first company to publicly disclose any details for an SBI demonstration, but it won’t be the last. Cinnamon said Apex will provide further updates on Project Shadow as it nears launch.
“We’re talking about it publicly because I believe it’s really important to inspire both the US and our allies, and show the pace of innovation and show what’s possible in today’s world,” Cinnamon said. “We are very fortunate to have an amazing team, a very large war chest of capital, and the ability to go do a project like this, truly for the good of the US and the good of our allies.”
