Direct peers

• Aerojet Rocketdyne (L3Harris): Aerojet Rocketdyne, now part of L3Harris, is the legacy U.S. leader in liquid and solid rocket propulsion and in-space thrusters. It is the most direct comparable to SPG as a propulsion-focused supplier serving defense primes, NASA, and commercial launch integrators.

Emerging players

• Ursa Major Technologies: Ursa Major is an emerging U.S. propulsion startup producing Hadley and Draper engines for small launch and hypersonic applications. It competes with SPG for emerging commercial and defense propulsion programs that prize additive manufacturing and rapid iteration.
• Rocket Lab: Rocket Lab designs and flies the Rutherford and Archimedes engines for its Electron and Neutron launch vehicles and offers the Space Systems business (spacecraft, separation systems, propulsion). It overlaps with SPG in small-launch and in-space propulsion.
• Relativity Space: Relativity developed the Aeon family of 3D-printed rocket engines for its Terran launch vehicles. Its additive-manufacturing propulsion approach overlaps with SPG's niche of novel, cost-efficient propulsion technologies.
• Firefly Aerospace: Firefly Aerospace produces the Reaver and Lightning engines powering its Alpha and MLV launch vehicles and the spacecraft bus for its Elytra orbital transfer vehicle. It is an emerging propulsion-and-spacecraft peer competing in small/medium launch and in-space mobility.

Broad incumbents

• SpaceX: SpaceX develops the Merlin and Raptor rocket engines for Falcon and Starship and operates the world's largest private launch fleet. While vertically integrated rather than a merchant propulsion supplier, it sets the benchmark for propulsion cost and cadence that SPG must compete against.
• Blue Origin: Blue Origin produces the BE-3PM, BE-3U, and BE-4 engines for its New Shepard, New Glenn, and for Vulcan customers. As a privately funded broad space incumbent with in-house propulsion, it represents both a competitor and a potential customer/supplier for SPG technologies.
• Northrop Grumman (Space Systems): Northrop Grumman's Space Systems segment produces solid rocket motors, kick stages, and in-space propulsion for defense and civil missions (e.g., GEM solid boosters, MEV). It is a broad incumbent that competes with and procures from propulsion suppliers like SPG.

Regional players

• Nammo: Nammo is a Norwegian-headquartered aerospace and defense company producing solid rocket motors, ramjets, and space propulsion components. It is a regional peer offering comparable propulsion technology, primarily serving European and allied defense markets.
• Mitsubishi Heavy Industries: Mitsubishi Heavy Industries manufactures the LE-series liquid and solid rocket engines for Japan's H-IIA/H3 launch vehicles. It is a regional incumbent comparable in scope of propulsion offerings but geographically separated from SPG's U.S. footprint.
