Making Earth radically more accessible by turning space into a global logistics network

Introducing Arc – the world’s first space-based delivery vehicle. Arc enables the on-demand delivery of cargo and effects to anywhere on Earth in under an hour, and offers unparalleled hypersonic testing capabilities. Arc reshapes defense readiness by enabling access to anywhere on Earth in under an hour – allowing for the rapid delivery of mission-critical cargo and effects to austere, infrastructure-limited, or denied environments. This capability establishes space as a new global logistics domain, introducing unprecedented speed, reach, and resiliency for national security. Arc features a versatile payload bay designed to accommodate a wide range of mission-critical cargo and effects. When launched to low-Earth orbit, Arc vehicles will form constellations of varying sizes and locations tailored to each customer’s needs. When called down on demand, Arc spacecraft descend from orbit, maneuver through hypersonic reentry, and touch down safely under parachutes – all autonomously.

Cool to see AFRL talking about this! At Inversion we've been focused from day 1 on building advanced re-entry vehicles to deliver cargo to remote locations. We’ve always believed the future of space-based delivery would require a new class of smaller scalable reentry vehicles. More to do, but closer every day!
BREAKING: The Pentagon is developing a way to launch military cargo into orbit, divide it among multiple reentry capsules, and deliver supplies near several battlefields from a single rocket. The Air Force and Space Force are moving away from the original Rocket Cargo concept, which centered on flying as much as 30 tons aboard one enormous reusable rocket. The new priority is a network of smaller, lower-cost capsules that can reenter independently and reach remote locations on land or at sea. The services jointly allocated $51.8 million to the Payload Delivery System effort in FY2026 and requested another $48.8 million for FY2027, according to Breaking Defense. AFRL has engaged SpaceX, Blue Origin, $RKLB, Sierra Space, Varda, Inversion Space, and Outpost Space as it seeks multiple capsule and launch providers. If successful, the Pentagon could pre-position critical supplies in orbit or launch them on demand, then send individual capsules toward forces operating across several distant or contested locations globally. The technology remains under development.

Inversion has been selected by @NASA to advance aerocapture technology for interplanetary missions. Aerocapture is a simple but powerful idea: use a planet’s atmosphere to slow down instead of fuel. Spacecraft arriving at another planet are traveling at tremendous speeds and traditionally must carry significant propellant to slow down and enter orbit. Aerocapture instead uses aerodynamic forces during a single controlled pass through the atmosphere to shed velocity and achieve orbital capture. Less fuel means mass savings that can enable greater flexibility in launch vehicle selection, increased science payload, and significantly shorter trip times. Under the contract, Inversion will study how Arc could support the demonstration through mission design, aerodynamics, trajectory analysis, and vehicle definition. This award represents a new frontier for Arc and highlights the growing range of missions enabled by advanced reentry.

Inversion is hiring across ALL disciplines. Including: Reentry. As part of the Reentry team, you’ll help Arc survive, maneuver, and operate through one of the most extreme environments any vehicle can face: hypersonic flight back from space. Thermal protection, aerodynamics, structures, GNC, testing – every discipline has to work together when a spacecraft hits the atmosphere at Mach 20+. Explore open roles: inversionspace.com/careers

Our CEO @jcfiaschetti shares the origin story of Inversion. Check out this clip from the MECO podcast hosted by @acolangelo. It’s part of a nearly hour-long conversation that dives into spacecraft design, first-principles engineering, advanced reentry, and the technical decisions shaping the future of returning from space.

This is an anechoic chamber – a room designed to minimize RF reflections and external interference to accurately characterize antenna performance under near free-space conditions. We just completed testing for a portion of Arc’s RF system. The goal: validate that our system performs as expected, including through our thermal protection system. Early results are very encouraging as we continue validating flight hardware ahead of Arc’s first flight.

Our drogue parachute deploys at supersonic speeds – making it a fundamentally different engineering challenge than the main parachutes for Arc. Made of Kevlar, the drogue is designed to withstand the extreme aerodynamic loads and temperatures in the wake of Mach 2+ speeds post reentry from space. Every drogue is cut, sewn, and tested in-house. We're not just designing the hardware, but building the manufacturing capability to produce it at scale.

A key differentiator of Arc is its high maneuverability. That means Arc can precisely shape its path through the atmosphere, access a wider range of landing locations, respond to changing mission conditions, and create unique, sustained flight environments for hypersonic testing.

Not exactly Times Square. But a better place to promote Arc as a scalable hypersonic test platform. Any guesses where we put this billboard? @georainbolt?
