As governments boost military budgets and buy commercial space services, early‑stage companies jostle with legacy primes for a slice of the action.

The world’s defense space market is no longer a closed shop. After two years of war in Europe and rising tensions across the Indo‑Pacific, military customers are moving faster and buying more from commercial providers—small launch firms, imaging upstarts, in‑space logistics outfits and software players once dismissed as “NewSpace.” The result: an arms‑length embrace between cash‑strapped defense buyers who want speed, and venture‑backed start‑ups that need predictable revenue.

Budgets go ballistic. NATO members collectively pushed military outlays to record levels through 2024 and into 2025, with many moving beyond the alliance’s 2% of GDP yardstick. In the U.S., the Space Force has designed acquisition pipelines expressly to tap the commercial market, while in Europe, Brussels is leaning on the European Defence Fund and new industrial initiatives to keep money—and know‑how—on the continent.

The Pentagon’s playbook gets commercial. Two programs set the tone in 2025. First, the National Security Space Launch (NSSL) Phase 3 “Lane 1” track opened routine national‑security missions to a rotating bench of providers, including on‑ramps for younger launch firms. In March, Rocket Lab and Stoke Space joined the original trio of SpaceX, Blue Origin and ULA, broadening competition for future task orders. Separately, Space Systems Command (SSC) issued the first Phase 3 task orders to SpaceX late last year—covering multiple Space Development Agency (SDA) launches and an NRO mission—signaling that commercial cadence and pricing would be rewarded.

Second, the Space Development Agency’s Proliferated Warfighter Space Architecture (PWSA) reached an inflection point. On September 10, SDA placed the first Tranche‑1 Transport Layer satellites on orbit, a milestone for the “buy, build, field” model that breaks big space programs into smaller, rapidly iterated “tranches.” Contracts now extend across dozens of primes and non‑traditionals, from bus makers to payload specialists.

And there’s a third leg forming: the Commercial Augmentation Space Reserve (CASR). SSC spent the spring and summer running wargames with commercial operators to practice “surging” private constellations during crises—laying the legal and technical groundwork for pre‑negotiated contracts that could add extra capacity for satcom, sensing and space‑domain awareness on short notice.

Europe scrambles to keep up. European institutions are also leaning into commercial players. Germany’s Isar Aerospace, for example, secured institutional launch agreements under ESA’s Flight Ticket Initiative this summer—marking a first for a privately funded European launcher—just as EU capital begins to flow into defense‑tech funds and the bloc’s new security instruments take shape. Meanwhile, Finland doubled down on ICEYE’s radar fleet, and France’s Unseenlabs continued to extend its RF‑sensing constellation—both signs that European capitals want sovereign data sources they can task in a crisis.

The procurement vibe: “show, don’t tell.” Defense buyers are still risk‑averse, but the bar to entry has changed. The companies winning in 2025 are those able to fly hardware, close cybersecurity audits, and demonstrate interop with government ground systems—then scale production quickly when called. The losers: bespoke science projects that can’t get beyond the demo stage.

Who’s chasing the windfall — and why they matter

• True Anomaly (US). Space‑domain awareness from space. The company won a $30 million Space Systems Command contract for the VICTUS HAZE tactically responsive‑space demo and inked a multi‑launch deal with Firefly to fly Jackal autonomous orbital vehicles. The bet: maneuverable inspector craft that can characterize suspicious spacecraft on demand.

• Impulse Space (US). High‑delta‑v “space mobility.” Fresh off a $34.5 million responsive‑space award for the VICTUS SURGO and VICTUS SALO missions, Impulse is positioning its Mira and Helios vehicles for rapid orbit changes, cislunar logistics and even same‑day LEO‑to‑GEO transfers. Expect dual‑use: defense proximity ops and commercial orbit‑raising.

• Stoke Space (US). Launch, but faster and cheaper. On‑ramped in March to NSSL Phase 3 Lane 1 with its fully reusable Nova, Stoke is vying to fly low‑risk national‑security payloads once operational—validating the Pentagon’s strategy of “racing” emerging providers into service.

• Rocket Lab (US/NZ). Not early‑stage anymore—but a newly minted defense prime. The company’s first PWSA satellite production award and Lane 1 on‑ramp status make it a bellwether for how a once‑small launcher can scale into military manufacturing.

• Apex (US). Satellite buses as products, not projects. Apex landed a roughly $46 million Space Force award in February and is scaling its Aries/Comet buses for SDA‑class constellations—an answer to schedule slips from bespoke bus integrators.

• Umbra (US). Sharper, cheaper synthetic‑aperture radar (SAR). Umbra advanced to Stage III of the NRO’s commercial radar program late last year and signed an R&D pact with NGA this spring—evidence that smaller SAR providers are now baked into U.S. GEOINT workflows.

• ICEYE (FI). Europe’s SAR workhorse with wartime validation. Backstopped by fresh Finnish R&D funding, ICEYE continues to expand a fleet that has supplied NATO allies and Ukraine—proof that persistent, all‑weather imaging is a must‑have, not a nice‑to‑have.

• BlackSky + HEO (US/AU). Non‑Earth imaging (NEI) for on‑orbit awareness. In August, BlackSky signed a seven‑figure deal with HEO to capture fast‑turn pictures of other spacecraft—turning idle imaging time into actionable SDA data feeds for defense users.

• Xona Space Systems (US). GPS‑like positioning from LEO. In February, Xona won a $4.65 million AFRL contract to demo resilient, centimeter‑level navigation in GPS‑challenged environments—an attractive hedge for autonomous systems on land, sea and air.

• Slingshot Aerospace (US). Signals of interference. The company secured SSC funding in January to expand global detection of GPS jamming and spoofing and is adding AI‑based “fingerprinting” of suspicious objects—software plumbing for a noisier orbital neighborhood.

• LeoLabs (US). Independent space‑traffic radar. With Space Force backing, LeoLabs is building deployable UHF arrays in the Indo‑Pacific and upgrading expeditionary sensors—giving civil and military operators higher‑fidelity catalogs outside traditional government networks.

• Kayhan Space (US). Autonomy for conjunction avoidance. Kayhan merged its Satcat and Pathfinder tools into a single platform this year and was tapped by the U.S. Office of Space Commerce for TraCSS pilots—positioning it as middleware between civil SSA and operator flight control.

• Scout Space (US). Hosted SDA sensors—headed to GEO. In April, Scout won a multi‑million‑dollar TACFI from SpaceWERX/SSC to field a new GEO‑class sensor and on‑board processing, with an Owl payload slated to fly on Blue Origin’s Blue Ring mission in 2026.

• Unseenlabs (FR). RF geolocation at sea. The company launched its BRO‑18 satellite in June and is expanding from maritime into terrestrial and space‑borne signals—data EU navies and coast guards increasingly want on tap.

• Isar Aerospace (DE). Europe’s institutional pathfinder. With ESA/EC launch agreements signed in August, Isar became the first privately financed European launcher to secure institutional “tickets”—a template for moving EU security payloads off foreign rockets.

Follow the money. On both sides of the Atlantic, the procurement pipelines are widening. In the U.S., SSC has said at least 30 NSSL Lane‑1 missions will be competed over the base ordering period, with additional on‑ramps for emerging providers. SDA’s tranche model now repeats every 24 months, and the Space Force is studying ways to migrate some data‑transport missions to lower‑cost commercial networks. CASR, meanwhile, is steadily building the legal and operational scaffolding to “surge” commercial services during crises. In Europe, the European Defence Fund’s 2025 work program opened 30‑plus calls, including space‑domain topics, while national investment arms—Finland’s Business Finland among them—are directly backing dual‑use space firms.

The catch. For start‑ups, defense demand is real—but so are the hurdles. Security clearances and export controls slow hiring; program delays can blow cash‑flow plans; and price pressure is intense as primes undercut bids to defend incumbencies. The prize is sticky revenue, but the path runs through production discipline and credible delivery timelines.

The outlook. With proliferated LEO architectures maturing, “software‑defined everything” payloads spreading, and launch options multiplying, a new class of venture‑backed companies is finally graduating from hype decks to order books. In 2025, governments don’t just want innovation—they want inventory. The start‑ups that can show up with flight‑proven hardware, secure interfaces and a plan to scale will win the work, while those still pitching PowerPoints will be left on the pad.
