Karman Holdings

Huntington Beach, United States commercial

Karman Holdings Inc., trading as Karman Space & Defense, is a publicly traded American manufacturer of launch-vehicle and missile structures, headquartered in Huntington Beach, California. The current company was formed in October 2020 through the merger of Aerospace Engineering LLC and AMRO Fabricating Corporation, though its manufacturing predecessors date back more than 40 years; it completed an initial public offering on the New York Stock Exchange in February 2025 under ticker KRMN, at an initial valuation of roughly $4 billion. For the 2025 fiscal year the company reported revenue of $471.5 million and about 1,400 employees, including 300 engineers, supporting more than 130 active programs. Karman organizes its hardware into three families: payload protection and deployment systems (encapsulation structures and low-shock separation and deployment mechanisms for sensitive payloads), aerodynamic interstage systems (the structures connecting rocket stages and fairings), and propulsion systems, including solid rocket motor cases and nozzles supplied through its Systima Technologies division. Its three end markets — hypersonics and strategic missile defense, tactical missiles and integrated defense systems, and space and launch — each contributed roughly 30-37% of 2025 revenue. Karman supplies structural and separation hardware that most launch-vehicle integrators buy rather than build in-house, making it a significant but little-known tier of the launch supply chain. Jon Rambeau became CEO in March 2026, succeeding Tony Koblinski.

GE Aerospace (NYSE: GE) is one of the world's largest aero-engine manufacturers. It is listed here for completeness rather than for an identifiable space division: GE Aerospace publishes no space systems business, and its FY2025 annual report contains no mention of spacecraft, satellites, launch vehicles or Space Force work. Its nearest activity to spaceflight is high-speed propulsion research, including a hypersonic test aircraft programme funded by the US Defense Innovation Unit, alongside additive manufacturing and power electronics that serve aviation rather than orbital customers. Earlier versions of this profile described satellite power conversion, thermal management and radiation-tolerant electronics as GE space products; none of that could be traced to a primary source, so it has been removed. Readers looking for the company's spaceflight heritage should note that the aerospace businesses General Electric once held in that field were divested long before the 2023 to 2024 separation that created today's GE Aerospace, GE Vernova and GE HealthCare.

Dawn Aerospace

Delft, New Zealand commercial

Dawn Aerospace, founded in 2018 and headquartered in Christchurch, New Zealand (with an R&D presence in the Netherlands), is developing a reusable suborbital spaceplane and green propulsion systems for satellites — pursuing a long-term vision of aircraft-like daily access to space using horizontally-launched, rocket-propelled vehicles that can fly multiple missions per day from conventional airstrips without large launch infrastructure. Dawn's Mk-II Aurora is an autonomous (uncrewed) suborbital spaceplane approximately 4 meters long, launched horizontally from an aircraft runway, powered by a nitrous oxide/propylene propulsion system. The Mk-II targets 100+ km altitude (Kármán line crossing) for microgravity research payloads, atmospheric science instruments, and space boundary experiments, with recovery via autonomous landing for rapid reuse. Flight testing of the Mk-II began in New Zealand in 2023 with approach-and-landing trials, working toward full rocket-powered ascent and hypersonic re-entry envelope expansion. The longer-term Mk-III concept targets orbital capability with a recoverable first stage and expendable upper stage. Dawn's satellite propulsion division manufactures green monopropellant thruster systems using hydroxylammonium nitrate (HAN)-based propellants — non-toxic, non-carcinogenic propellants with density impulse superior to hydrazine for small satellite applications. These thrusters are sold to satellite bus manufacturers and constellation operators as drop-in replacements for hydrazine monopropellant systems, avoiding the extensive ground safety equipment and handling procedures hydrazine requires. Dawn's New Zealand base leverages RocketLab's regulatory precedent for commercial launches from NZ airspace, the country's Southern Hemisphere orbital trajectory advantage, and a growing local aerospace manufacturing ecosystem. The company competes with Hermeus, Reaction Engines, and Virgin Galactic in reusable spaceplane development, and with Bradford ECAPS, Aerojet Rocketdyne, and Benchmark Space Systems in green smallsat propulsion.

Radian Aerospace

Seattle, United States commercial

Radian Aerospace is developing Radian One, a horizontal takeoff/landing single-stage-to-orbit spaceplane—the 'holy grail' of space transportation. The vehicle will launch from a 3+ kilometer rocket-powered rail sled, reaching orbit with rocket engines before runway landing, capable of flying again in 48 hours. Radian One will carry five people and 2,270 kg cargo to LEO. In April 2025, the company unveiled the R3V (Radian Reusable Reentry Vehicle) platform for near-term revenue generation. Radian partnered with General Atomics in March 2025 for advanced avionics. The company's ambitious SSTO design could revolutionize space access if successful.

Space Transportation

Beijing, China commercial

Space Transportation (凌空天行, Lingkong Tianxing) is a Beijing-based Chinese commercial aerospace company founded in 2018 developing a family of reusable winged rocket-powered vehicles for suborbital cargo transport, hypersonic point-to-point passenger transport, and eventual low Earth orbit access — pursuing an alternative architecture to vertical-launch rockets by leveraging the aerodynamic efficiency and runway landing capability of spaceplane designs. The company's Tianxing vehicle family is designed for horizontal runway landing, recovering the vehicle for rapid reflight similarly to an aircraft. The near-term commercial target is hypersonic point-to-point (P2P) cargo and passenger transport: a suborbital trajectory that reaches Mach 5-20 enables cargo delivery from China to Europe in 1-2 hours, or passenger transport in 3-4 hours compared to 10-12 hours by conventional aircraft — a market Space Transportation is targeting alongside competitors Sierra Space's Dream Chaser and Hermeus in the West, and Rocket Cargo and DARPA's DRACO for military applications. Space Transportation has conducted multiple hot-fire tests of its rocket engines and vehicle flights, with significant Chinese venture capital backing from investors including Shunwei Capital and other top-tier Chinese funds. China's civil-military fusion (CMF) industrial policy means Space Transportation's hypersonic spaceplane technology has dual defense significance for the People's Liberation Army Rocket Force alongside its commercial transport applications. The company competes within China's commercial spaceplane sector alongside Lingkong Hypersonics and the Beijing-based teams developing winged reusable launch vehicles, and internationally with Sierra Space, Rocket Lab's future reusable plans, and Hermeus.

SpinLaunch is a Long Beach, California company developing a kinetic energy launch system that uses a ground-based centrifuge to spin-accelerate small payloads to hypersonic speeds before releasing them vertically, reducing the fraction of propellant required for a launch vehicle. Founded in 2014 by Jonathan Yaney, the company raised over $150M from investors including Airbus Ventures, Google Ventures, and Kleiner Perkins. SpinLaunch completed construction of a 33-meter suborbital accelerator at Spaceport America in New Mexico and conducted 10 successful test launches between October 2021 and September 2022, demonstrating the core kinetic launch concept. The company plans a full-scale orbital system capable of delivering 200 kg payloads per day. Critics note that rapid-rotating electronics must survive ~10,000g acceleration, limiting payload options primarily to rugged government and mass-production commercial satellites.

Arceon

Delft, Netherlands commercial

Arceon is a Dutch advanced materials company based in the Netherlands, operating out of the ESA space cluster in the Noordwijk area, that produces Carbeon — a proprietary silicon carbide fiber-reinforced silicon carbide matrix ceramic matrix composite (SiCf/SiCm CMC) capable of maintaining structural integrity at temperatures up to 1600°C, with excellent oxidation resistance and low density compared to refractory metals. Ceramic matrix composites represent the materials frontier for extreme-temperature aerospace applications: unlike ablative thermal protection systems (PICA, AVCOAT) that erode on each reentry and require replacement, structural CMC components are designed to be reusable — a critical advantage for the reusable launch vehicle era. Arceon's Carbeon targets applications including reentry heat shields for capsules and lifting bodies, rocket nozzle extensions and combustion chamber inserts (replacing ablative carbon-carbon or tungsten), hypersonic vehicle leading edges and control surfaces, and high-temperature structural brackets in satellite propulsion systems. Arceon graduated from the ESA Business Incubation Centre (BIC) at ESTEC in Noordwijk in 2023 — co-located with Europe's main space engineering campus — providing access to ESA's materials testing facilities, European space prime contractor networks, and ESA's TRL maturation funding. Validation of Carbeon in space environments progressed significantly when samples were sent to the International Space Station aboard SpaceX CRS-31 (the 31st Commercial Resupply Services mission), exposing the material to microgravity, vacuum, atomic oxygen, and thermal cycling conditions that simulate orbital reentry stresses before qualification for flight hardware. The Dutch deep-tech ecosystem — Delft University of Technology's materials science programs, NL Space Office funding instruments, and proximity to Airbus Defence and Space, RUAG, and other European space prime suppliers — supports Arceon's development path. Primary competitors include Safran/Herakles (CMC for Ariane 6 nozzle extensions), Albany Engineered Composites (US carbon-carbon and CMC), SGL Carbon, and established refractory ceramic manufacturers like CoorsTek for niche structural applications in rocket propulsion.
