The U.S. Space Force's roster of companies eligible to bid on national security launches just got two names longer — and one of them isn't even a rocket company in the traditional sense. On July 7, 2026, Space Systems Command announced it had admitted Impulse Space and Relativity Space into the National Security Space Launch (NSSL) Phase 3, Lane 1 contract vehicle. That brings the pool of qualified providers to seven, alongside SpaceX, United Launch Alliance, Blue Origin, Rocket Lab, and Stoke Space.
Each new entrant received a $5 million task order to begin initial capability assessments — the government's way of kicking the tires before real mission money is on the line. Admission to Lane 1 doesn't guarantee either company an actual launch contract; it simply pre-qualifies them to compete for task orders as they come up.
What Lane 1 Actually Is
NSSL Phase 3 splits national security launch procurement into two tracks. Lane 1 is the lower-barrier, higher-competition lane, structured as an indefinite-delivery/indefinite-quantity (IDIQ) vehicle worth up to $5.6 billion. It's designed for missions the Space Force considers more tolerant of risk — a deliberate on-ramp for newer or less-flight-proven vehicles that wouldn't necessarily clear the bar for Lane 2's most sensitive, highest-assurance payloads.
That framing matters for judging what just happened. Getting into Lane 1 is not the same as being declared combat-ready for a exquisite reconnaissance satellite. It's closer to being added to a bench of vetted contractors who can now formally bid when the Space Force puts out a Lane 1 task order.
Two Very Different On-Ramps
Relativity Space's inclusion follows a familiar script for the program: a launch vehicle developer pursuing government business with its flagship rocket, in this case the reusable, medium-lift Terran R. The catch, and it's a significant one, is that Terran R has not yet flown — Relativity expects its first launch later this year. The company is effectively asking the Space Force to bet on a vehicle that exists on paper and in hardware testing rather than on a flight record.
Impulse Space's addition is the more unusual of the two. Impulse doesn't build launch vehicles at all — it's largely focused on orbital transfer vehicles, and its offering here is Helios, a high-energy upper stage designed to move payloads from low Earth orbit to higher, more useful orbits after a separate launch vehicle has already done the heavy lifting. According to Air & Space Forces Magazine, that makes Helios a first for the NSSL program: an orbital-mobility product, rather than a rocket, being pre-qualified as its own line item. That's a distinct role in the launch chain, and the Space Force apparently now considers it something it can procure directly through Lane 1 rather than only as a subcontracted add-on to someone else's rocket.
Impulse Space president and COO Eric Romo was quoted in Air & Space Forces Magazine's coverage of the announcement: "This award is a big validation of the capabilities we're delivering at Impulse, and we're honored to support national security objectives for our country."
The Official Rationale
Col. Eric Zarybnisky, the acting portfolio acquisition executive for space access at Space Systems Command, framed the expansion around tempo. "This is critical at a time when our launch cadence is rapidly increasing," he said, according to Air & Space Forces Magazine. The Space Force has spent the past several years trying to shorten the list of ways a single provider's schedule slip or anomaly can stall national security missions — and broadening the Lane 1 bench is one of the more direct levers available for that.
Why It Matters
For most of the past decade, national security launch has effectively meant a short list: ULA, and more recently SpaceX, with Blue Origin working its way in. Rocket Lab and Stoke Space joining Lane 1 already signaled the Space Force's appetite to widen that circle. Adding Impulse and Relativity Space pushes further in the same direction, but with two different kinds of bets attached.
Relativity represents the standard risk of pre-flight hardware — the Space Force is pre-qualifying a rocket that still has to prove it can reach orbit before any task order becomes a real mission. Impulse represents something more structural: an acknowledgment that orbital transfer vehicles are becoming their own procurement category, separate from the launch itself. If the Space Force starts routinely buying "last mile" orbital mobility as its own line item, that reshapes how launch contracts get bundled — and potentially opens the door for other in-space mobility companies to pursue primes status without ever building a rocket.
None of this guarantees either company flies a national security payload soon. The $5 million task orders are for capability assessments, not missions, and Lane 1's lower-risk framing means the Space Force retains plenty of latitude in how much real business flows to any given provider. But the roster expansion — now seven deep — is a concrete signal that the Pentagon wants more paths to orbit, and more kinds of companies competing to provide them, than it had even two years ago.
