Inversion

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.

As the United States looks to scale hypersonic testing, commercial space offers the cadence, affordability, and flight conditions the field has been missing. Read more about space as a hypersonic testing domain from Inversion CEO @jcfiaschetti here: bit.ly/4a9kWyZ

Reentry is hot. We’re deep in the throes of Thermal Protection System (TPS) testing at Inversion. Our spacecraft Arc relies on it to survive the high hypersonic conditions of reentry. Our in-house TPS testing capability allows us to expose materials to extreme flight-representative heat fluxes and temperatures to validate our designs long before they go to space. Arc uses a proprietary material we can’t show — so in this video we’re torching cork.

I'm convinced that Space is the answer to scalable hypersonic testing. Everyone knows that the U.S. is behind in hypersonics and is working hard to catch up. Spending on hypersonics rose from ~$3.8B in 2022 to ~$6.9B in 2025. Pouring more money into legacy testing methods will yield the same inadequate results. The US's investments should follow the industry where market forces are bringing costs down and increasing flight rate: commercial space. 🧵

One year ago today our first spacecraft Ray launched to orbit. Here's a photo Ray just took — we're still in contact with her regularly. Ray’s mission was a major milestone for Inversion. With a team of just 25 people, Ray was designed, built, tested, and flown at an order of magnitude lower cost than comparable spacecraft. Ray delivered substantial technical validation and invaluable real-world operational experience for the team. A few key technologies successfully tested include: • Two major delta-v maneuvers • Our in-house designed separation system • Validation of our full avionics stack • Repeated on-orbit software updates The final planned milestone, controlled reentry, was not executed due to a short circuit that prevented deorbit engine ignition. Ray has since been repurposed as a long-duration on-orbit testbed, and we continue to maintain full control of the spacecraft. Ray’s mission provided the team with deep technical validation and operational insight. Everything we learned and built — from in-space systems to software to operations — now carries direct flight heritage into our next spacecraft: Arc.

2025 was a flagship year for Inversion. We launched our first spacecraft to orbit, doubled the team, moved into a new Los Angeles facility, conducted dozens of drop tests, joined the nation’s premier hypersonic program of record, and unveiled Arc – the world’s first space-based delivery vehicle. None of this happens without incredible customers and an extraordinary team. Thank you for building with us. 2026 is going to be even bigger.

Inversion is proud to be selected for the Missile Defense Agency’s SHIELD IDIQ contract. SHIELD will build and evolve the U.S. homeland’s layered defense against hypersonic, ballistic, and other advanced aerial threats. Inversion brings a rapid, affordable, and scalable approach to testing and maturing next-generation missile defense capabilities.

Arc directly contributes to two of six Critical Technology Areas for the @DeptofWar 1. Contested Logistics Technologies: Arc’s primary mission enables access to anywhere on Earth in under an hour — allowing for the rapid delivery of mission-critical cargo to austere, infrastructure-limited, or denied environments. 2. Scaled Hypersonics: Arc provides unmatched hypersonic testing capabilities, including maneuverability at Mach 20+, prolonged time on condition, and sustained high g-loading. Fully reusable and capable of precise landings for rapid recovery, Arc makes hypersonic testing faster, repeatable, and more affordable.

Arc is not a one-trick pony.   Beyond its delivery missions, Arc provides unmatched hypersonic testing capabilities, including maneuverability at Mach 20+, prolonged time on condition, and sustained high g-loading.   Clip from our CEO @jcfiaschetti’s interview with @ti_morse on @relentless

To our veterans, thank you for protecting this beautiful nation 🇺🇸

"Help has arrived… From orbit." A thorough look at the capability Inversion is creating with Arc.

Arc is a new kind of spacecraft. Not quite a capsule, not quite a spaceplane. It’s based off of a lifting body design – ideal for its mission to deliver cargo from orbit to anywhere on Earth in under an hour.

From avionics to supply chain, business ops to mission management – we are looking for creative, passionate, and unrelenting individuals to join our team. Check out openings: inversionspace.com/careers

Space nerds, yes. Design nerds, also yes. We designed the Arc spacecraft logo in-house – striving for a simple, but elegant emblem. Something that could one day be instantly recognizable like the Nike swoosh or NY Yankees logo but still with a touch of aerospace heritage.

Thanks for coming by @ti_morse! Great long form interview with our CEO @jcfiaschetti below ⬇️

Meet Jaws and Big Tuna, our autonomous drop test vehicles. Our Arc spacecraft isn’t just built to survive reentry - it’s built to land precisely wherever it’s needed within feet of its target. The team regularly conducts drop tests to refine our guidance system and autonomy algorithms.

The future should be beautiful. As we work to make space a new global logistics domain, each vehicle we build will strive to inspire – with both form and function.

We're big fans of Scott Manley @DJSnM over here at Inversion, so you can imagine our delight when he built our Arc spacecraft in Kerbal and took it for a spin. Watch our founders @jcfiaschetti and @_abriggs react to Scott's video, answering questions and diving deeper into Arc's design and mission.
