Relativity Space

Forward Guidance

Relativity issues no financial guidance. Its published operating targets are programmatic: first Terran R flight from Launch Complex 16 (LC-16) at Cape Canaveral Space Force Station in late 2026; support for NASA's Aeolus Mars science partnership with a planned 2028 departure; and construction of an additional Terran R production facility in Florida with broader expansion through 2034. Because Relativity does not publish audited financial statements, Defense Briefing cannot independently determine revenue recognition, cash burn, liquidity or profitability. Terran R's first flight remains the central public operating milestone for beginning execution of the company's launch manifest.

Relativity Space builds rockets and, increasingly, the spacecraft that ride on them. Its single flight product in development is Terran R, a two-stage, partially reusable launch vehicle sized between SpaceX's Falcon 9 and Blue Origin's New Glenn. The commercial proposition is straightforward: a second high-cadence, medium-to-heavy American lift option for satellite operators who currently have very few alternatives to SpaceX for large constellation deployment.

The company originally intended to 3D print essentially an entire rocket using its proprietary Stargate robotic deposition platform. Under the current management team that ambition has been narrowed. Additive manufacturing remains central to engine hardware and selected structures, while tanks, domes and fairings now use conventional fabrication and outside suppliers. The additive capability also supports Horizon Manufacturing Technologies, a stand-alone business unit within Relativity that applies the Stargate platform to large-scale metal manufacturing for aerospace, defense, energy and other industrial markets.

For national security customers the relevant fact is capacity, not novelty. Relativity holds LC-16 at Cape Canaveral Space Force Station, more than 300 acres of test infrastructure at NASA Stennis Space Center and, since 08-JUL-2026, one of seven positions on the National Security Space Launch (NSSL) Phase 3 Lane 1 contract. It has not yet placed a payload in orbit.

Terran R Launch Vehicle

Terran R is a 284-foot, two-stage launch vehicle burning liquid oxygen (LOX) and subcooled liquid methane. The first stage carries 13 Aeon R gas generator cycle engines, nine gimbaling and four fixed, producing 3,497,000 pounds-force of liftoff thrust. The second stage uses a single vacuum-optimized Aeon V producing 323,000 pounds-force. Published payload performance is 33,500 kg to low Earth orbit (LEO) fully expended, 23,500 kg to a 200 km LEO with booster recovery and 5,500 kg to geostationary transfer orbit (GTO). Booster recovery follows the now-conventional profile: cold-gas flip, entry burn, grid fin control, landing burn and touchdown on a downrange recovery vessel, followed by inspection and refurbishment. Early flights are engineering validation; higher reuse cadence is deferred to later blocks.

Aeon R and Aeon V Propulsion

Aeon R is a high-pressure gas generator cycle LOX/methane engine rated at 269,000 pounds-force at sea level. It completed a full-power mission duty cycle in May 2024 and was qualified in July 2025. Relativity reports more than 300 Aeon R hot fire tests to date, with all 13 engines for the first flight's booster through acceptance testing. Aeon V development testing continued into 2026. Engine and stage testing runs at NASA Stennis, where Relativity leases the A-2 stand and is raising its thrust capacity from the original 650,000 pounds to more than 3.3 million pounds to permit vertical full-stage firing.

Interplanetary Spacecraft (Aeolus Mars Orbiter)

Under a NASA public-private partnership announced 17-JUN-2026, Relativity will build the spacecraft bus, provide the Terran R launch and conduct cruise operations for the Aeolus Mars atmospheric science mission, scheduled to launch in 2028. NASA Ames Research Center designs, builds and integrates the four-instrument payload suite: the Doppler Wind and Temperature Sounder, the Thermal Limb Sounder, the Surface Radiometric Sensor Package and the Wide-Field Context Camera. NASA describes the instrument partnership as its first six-year reimbursable Space Act Agreement. NASA supplies the science payload while Relativity supplies the spacecraft, rocket and cruise operations. The agency has not published a value for Relativity's contribution.

Horizon Manufacturing Technologies

Horizon is a stand-alone business unit established in 2025 to commercialize the Stargate large-format metal deposition platform outside launch. Its target is substitution for large castings and forgings in energy, defense, aerospace and maritime supply chains, where lead times run to months and capacity is geographically concentrated. Quan Lac, formerly vice president of additive manufacturing at Siemens Energy, serves as president.

Dark Matter Lab

Dark Matter Lab is a high-autonomy innovation lab within Relativity Space. Relativity describes it as a small team focused on rapid deep-technology experimentation and hardware-software prototyping. Public materials do not identify a fixed program portfolio.

Terran 1 (Retired)

Terran 1 was a small expendable vehicle powered by nine Aeon 1 engines with a single vacuum variant on the upper stage, rated at 1,250 kg to a 185 km LEO and advertised at $12 million per mission. Its only flight, "Good Luck, Have Fun," launched from LC-16 on 22-MAR-2023 local time (23-MAR-2023 UTC), passed maximum dynamic pressure at T+1:20 and then suffered a second-stage anomaly short of orbit. Relativity retired the vehicle in April 2023.

Tim Ellis and Jordan Noone founded Relativity Space in 2015 on a thesis that additive manufacturing would compress rocket build times and part counts by an order of magnitude. The company signed a 20-year lease at NASA Stennis in March 2018, won a competitive Air Force process for LC-16 at Cape Canaveral in January 2019 and announced a Vandenberg polar pad in 2020. It moved its headquarters and factory to Long Beach in February 2020, then took over the former Boeing C-17 production plant, roughly one million square feet, in 2022 for Terran R.

Capital arrived quickly. A $500 million Series D in November 2020 valued the company near $2.3 billion; a $650 million round led by Fidelity in June 2021 lifted the mark to $4.2 billion and brought total venture funding to $1.335 billion. Investors included Baillie Gifford, BlackRock, Coatue, General Catalyst, ICONIQ Capital, Tiger Global and Y Combinator.

The March 2023 Terran 1 flight validated the structure but not the mission. Relativity retired the vehicle weeks later and went all in on Terran R, a decision that removed near-term revenue while extending the development burn. By 2024, secondary reporting described a tightening capital position. On 10-MAR-2025 Relativity named Eric Schmidt chief executive amid a reported change-of-control transaction, and Ellis moved off the executive line. Relativity did not disclose the transaction price or a new valuation. At the same time, the company reported more than $2.9 billion in Terran R launch backlog.

The Schmidt-era pivot has three visible components. First, engineering pragmatism: 3D printing is now a tool rather than the product, and outside suppliers carry structures the company once insisted on printing. Second, business separation: Horizon Manufacturing Technologies was established as a stand-alone business unit within Relativity, while Dark Matter Lab remains an internal innovation lab. Both extend the company's technology base beyond the Terran R launch program. Third, mission-side vertical integration: the Aeolus agreement makes Relativity a spacecraft prime, not only a launch provider. There have been no corporate acquisitions by Relativity in this period; the March 2025 change of control is the only structural transaction on the record.

Relativity does not publish revenue, profitability, cash-flow or liquidity figures. The company reports more than $3 billion in pre-sold launch contracts across more than a dozen customers, including commercial and government counterparties. Those launch service agreements should not be treated as current revenue: payment timing, milestone structure, cancellation terms and revenue-recognition policy are not publicly disclosed.

Three operating drivers are visible from the public record. First, Terran R must reach orbit and begin flying the contracted manifest. Second, a successful Terran R launch would satisfy the flight prerequisite for competing for National Security Space Launch Phase 3 Lane 1 mission task orders. The Lane 1 contract ceiling was increased to $17 billion on 17-JUL-2026, but that is a shared program ceiling across seven providers and is not Relativity backlog. Third, Horizon manufacturing work, NASA's Aeolus partnership and Defense Logistics Agency additive-manufacturing work provide non-launch program exposure, although Relativity does not disclose the revenue contribution of any of those activities.

Not publicly disclosed. Relativity does not publish a board roster, and as a private company it files no proxy statement. Confirmed board-level facts: Eric Schmidt serves as Executive Chairman, Maria Seferian serves as Executive Vice Chair, and co-founder Tim Ellis remained on the board following the March 2025 leadership change. Any further composition is unverified and is therefore omitted rather than inferred.

N/A — no Section 16 reporting. Relativity has no registered class of equity securities, so no Forms 3, 4 or 5 exist. The only disclosed insider-adjacent transaction of record is the March 2025 acquisition of a controlling interest by Eric Schmidt, the terms of which were not made public.

What this means for national security. The Space Force is short on lift. Lane 1 expected mission volume has grown from roughly 60 at the June 2024 award to approximately 170 over the coming decade, and launch backlog has already delayed on-orbit capability for customers including the Space Development Agency. Adding a seventh Lane 1 provider is a hedge against provider concentration, not a near-term capacity fix. Relativity contributes no launch capacity to the national security manifest until it flies and completes tailored mission assurance. The $5 million task order buys the government an assessment, nothing more.

What this means for capital. There is no listed exposure. The last widely reported funding-round valuation was $4.2 billion in June 2021. The March 2025 change-of-control transaction was reported on undisclosed terms, so current valuation cannot be established from company disclosure. Public-market read-through runs through the competitive set: a successful Terran R debut compresses pricing power at the medium-to-heavy tier and is directionally negative for incumbents dependent on scarcity of alternatives to SpaceX, while a failure reinforces the current duopoly-plus structure. Watch instead for a priced round, a secondary transaction or an initial public offering filing after first flight; that is the first moment a defensible valuation exists.

Catalysts to watch. Terran R stage acceptance and static fire at Stennis A-2; LC-16 activation milestones including tank farm and flame trench completion; first flight window confirmation; the first Lane 1 task order competition Relativity is eligible to bid; Aeolus spacecraft critical design review; and formal site selection and permitting on the Space Coast campus.

Relativity's durable assets are physical and contractual rather than technological. LC-16 is a leased Cape Canaveral pad with an exclusive operator position, and pads on the Eastern Range are genuinely scarce. Its Stennis footprint, more than 300 acres including the A-2 stand being uprated from 650,000 pounds to more than 3.3 million pounds of thrust capacity, is the largest commercial presence at the center and is difficult for a new entrant to replicate. The company-reported $3 billion-plus launch manifest and Lane 1 position represent commercial access and procurement optionality, not guaranteed revenue.

The original moat thesis, that printing an entire rocket would deliver a structural cost and cycle-time advantage, has been substantially retired by the company itself. Tanks, domes and fairings now come from conventional processes and outside vendors, which means Terran R competes on the same industrial terms as its peers. What survives of the additive program is being monetized separately through Horizon, where large-format WAAM addresses a real bottleneck in castings and forgings for energy, defense and maritime customers. That business is credible on its own merits; it is not a launch moat.

The clearest structural weakness is the absence of a flying revenue base. SpaceX, Rocket Lab and United Launch Alliance all fund development from operating vehicles. Relativity funds development from a single balance sheet controlled by one shareholder. That concentrates decision speed, and it concentrates risk.

Execution. Terran R has slipped repeatedly from an original no-earlier-than 2024 posture to a late 2026 target. First flights of new medium-to-heavy vehicles fail at a material rate, and Relativity's only orbital attempt to date did not reach orbit. Early-flight recovery performance and orbital mission success are both material execution tests; the public record does not support assigning a market probability to either outcome.

Capital concentration. One shareholder controls the company and, in practice, its funding. There is no public market, no disclosed cash position and no committed external facility on the record. Relativity does not disclose current liquidity, external credit facilities or the funding commitments supporting Terran R development. That limits independent assessment of capital runway.

Customer concentration. Backlog sits with a handful of satellite operators, several of which have consolidated or restructured since signing. OneWeb is now inside Eutelsat, and constellation replenishment plans have shifted. Manifest values signed in 2022 and 2023 are not guaranteed to survive to launch on the same terms.

Government position without government revenue. Lane 1 eligibility requires a successful launch before task order competition. The $5 million assessment task order is not a launch contract. Program-level budget growth for Space Force launch improves the opportunity set but does not de-risk Relativity's access to it.

Governance and disclosure. No proxy statement, no published board roster, no audited financials and no stated valuation since 2021. Analysts working from secondary marks or headcount aggregators are working from estimates, not from company disclosure. This profile flags those fields rather than filling them.

Facilities and schedule dependency. LC-16 activation, the Stennis A-2 uprate and the new Florida campus are concurrent construction programs. Any one of them slipping compresses the launch schedule further, and the Space Coast expansion is tied to state incentive eligibility with performance conditions extending to 2034.
