Space Force ACES: Security Clearances for Space Startups
TL;DR: On October 22, 2026, the US Space Force's Commercial Space Office announced ACES (Access to the Classified Ecosystem for Space), an effort to help commercial space companies get the security clearances they need to compete for classified military work. It does not open the door to everyone: a company still needs a government sponsor with a real operational need. The same week, the Space Force named six companies to its first operational Commercial Augmentation Space Reserve (CASR) contracts. For space startups, the message is clear. The classified market is opening a little wider, and the companies that win will be the ones that build sponsors, trust and proof before they ask for access.
Key takeaways
- Security clearances have long favored established defense contractors. ACES is the Space Force's attempt to lower that barrier for commercial companies.
- ACES is sponsor-driven, not open enrollment. Your first sales job is finding a government customer with a confirmed need for what you build.
- Trust is the real currency. The six CASR companies were picked because operators already rely on them.
- "Living program" language from the Space Force means the door stays open to new entrants that prove themselves.
- Startups should market for two audiences: the sponsor who needs the capability and the program office that must trust the company behind it.
What did the Space Force announce?
Here is the news in short. As SpaceNews reports, the Space Force is now helping commercial space companies obtain the security clearances needed to compete for classified work, a long-standing obstacle that has favored established defense contractors over startups with new technology.
SatNews reports that Col. Tim Trimailo, director of Space Systems Command's Commercial Space Office, unveiled the program at the 2026 LA Space Week Space Industry Days in El Segundo, California. The key points:
- The problem it targets. Commercial vendors with mature solutions get stuck outside classified programs because of clearance delays. Without clearances, the government cannot brief them on threats or classified requirements.
- How it works. ACES aims to identify security access needs early and help companies work through the process alongside their government sponsors.
- Who is involved. The Commercial Space Office is working with SpaceWERX and the Defense Innovation Unit, using Other Transaction Authority agreements to guide companies through security vetting.
- What it is not. ACES is not an open path for companies to request clearances on their own. A vendor first needs an active government sponsor with an identified operational need.
Trimailo put the case plainly: "Without the appropriate security access, the government cannot fully engage industry partners on relevant threats, capability requirements, and mission needs."
ACES builds on a model DARPA tested. DARPA's BRIDGES pilot was designed to connect small companies that do not usually work with the government to classified research problems, including sponsoring them for facility clearances. SatNews notes that BRIDGES wrapped up in 2025 after supporting 19 space companies.
The companion news: CASR's first operational contracts
The same office made a second announcement that week. Air & Space Forces Magazine reports that the Space Force picked six space domain awareness companies for the first operational contracts under its Commercial Augmentation Space Reserve: Anduril, Intrack, Slingshot, LeoLabs, Australia's EOS and Canada's NorthStar. CASR is meant to let the military tap commercial capacity in steady state and surge it in a crisis.
Officials said the six were chosen because operators already trust them, and all six already work with the Space Force's Joint Commercial Operations cell. Trimailo also stressed that CASR is "a living program" that is "always looking for new entrants." The initial contract values were not disclosed, and officials described them as fairly low.
Why does this matter for space companies?
Put the two announcements side by side and a pattern appears. The Space Force wants more commercial capability, but it buys from companies it already trusts, and it can only share its hardest problems with companies that hold the right access.
That matters for three reasons.
First, it changes the shape of the sales cycle. For classified work, a clearance is not a box you tick at the end. It decides whether you can even hear the real requirement. ACES is designed to surface that need earlier, which means startups should plan for it from the first serious conversation.
Second, the sponsor is now the gatekeeper. Because ACES requires a government sponsor with a confirmed need, the first person you have to convince is not a security officer. It is a program or operations customer who wants your capability badly enough to back you.
Third, trust compounds. The CASR six did not get picked from a cold proposal. They were already supporting operators. Every pilot, demo and small contract you deliver today builds the track record that gets you into the next, bigger door.
Who wins and who loses?
ACES is new, and the details of how fast it moves will matter. But the design points to some likely winners and losers.
Likely winners
- Startups with a mission champion. Companies that already have an operator or program office asking for their capability can now use that sponsor to start the clearance process sooner.
- Commercial firms with mature, flight-proven tech. The program targets vendors with real solutions that have been blocked by access, not ideas looking for a customer.
- Companies already working with the government. The CASR picks show that existing relationships, such as work with the Joint Commercial Operations cell, carry real weight.
- SpaceWERX and DIU performers. With both organizations involved, companies already in those pipelines may find it easier to connect with sponsors.
Likely losers
- Startups that lead with "we need a clearance." Without a sponsor and a confirmed need, ACES is not a shortcut. Asking for access before showing value will go nowhere.
- Companies with no public proof. If operators cannot see what you have delivered, they cannot vouch for you, and trust is what got the CASR companies in.
- Incumbents relying on the clearance moat. Established contractors have benefited from the clearance barrier. If ACES works, more commercial competitors will be in the room.
Fair warning: a framework is not a contract. The real test is how many companies actually get cleared, and how quickly.
What should space entrepreneurs do now?
Here are five practical moves for space companies that want to sell into national security space.
1. Map your sponsor before you map your clearance
Because ACES runs through government sponsors, list the specific program offices, operators and labs that have a mission need your product solves. Then build a plan to reach and educate each one. Our playbook on how to sell to the Space Force walks through how to find and work those buyers.
2. Turn small wins into visible proof
The CASR companies were chosen because operators already depend on them. Make your own track record easy to see: pilots, demos, data deliveries and contract awards, presented in order. If much of your work is under NDA, our guide to case studies for space companies shows how to share proof without breaking confidentiality.
3. Use non-dilutive programs as a door, not just funding
SpaceWERX and DIU are part of ACES. Programs like SBIR are often the first way a startup gets in front of a government customer who could later sponsor it. Read our breakdown of SBIR Phase 1 for space startups to see how to approach it with sales in mind.
4. Market carefully in a sensitive space
More access to classified programs means more care with what you publish. You can still build a strong public brand around outcomes, people and unclassified results. Our guide to ITAR-safe marketing covers how to stay visible without oversharing.
5. Partner with primes while you build your own access
Large contractors already hold clearances and classified contracts. Being a trusted supplier to them can put your technology inside classified programs while your own access is in progress. See selling to prime contractors in space for how suppliers win that work.
How does this change positioning for space companies?
For defense-focused space startups, positioning now has two jobs. It has to show a sponsor that you solve an urgent mission problem, and it has to show a program office that your company is mature enough to trust with sensitive work.
Three questions are worth answering this quarter:
- Who is our sponsor, by name? If you cannot name the government customer who needs you, start there.
- What proof do operators already have? List every pilot, demo and delivery, and make it easy for a champion to share.
- What do we say when we win? When you land a contract or a program slot, have an announcement plan ready. Our contract announcement playbook lays out the first 30 days.

Frequently asked questions
What is the Space Force ACES program?
ACES stands for Access to the Classified Ecosystem for Space. It is an initiative from Space Systems Command's Commercial Space Office, announced on October 22, 2026, to help commercial space companies get the security clearances they need to work on classified national security space missions.
Can any space startup apply to ACES for a clearance?
No. According to SatNews, ACES is not an open path for companies to request clearances on their own. A company first needs an active government sponsor with an identified operational need for its capability.
Who is working with the Space Force on ACES?
The Commercial Space Office is working with SpaceWERX and the Defense Innovation Unit, using Other Transaction Authority agreements to help companies through security vetting. The approach builds on DARPA's BRIDGES pilot, which SatNews says supported 19 space companies before it ended in 2025.
What is the Commercial Augmentation Space Reserve?
The Commercial Augmentation Space Reserve, or CASR, is a Space Force program to use commercial space capabilities in normal operations and surge them during a crisis. Its first operational contracts, announced in October 2026, went to six space domain awareness companies: Anduril, Intrack, Slingshot, LeoLabs, EOS and NorthStar.
How can space startups prepare to sell into classified programs?
Find a government sponsor with a real need for your product, build a visible record of pilots and deliveries, use programs like SBIR and SpaceWERX as entry points, market carefully around sensitive details and consider supplying prime contractors while you build your own access.
