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.

Advanced reentry starts in the lab. Our custom torch stand moves heat shield test samples through dynamic thermal conditions, helping us simulate the extreme, rapidly changing heat flux spacecraft experience during flight.

SpaceX doesn't go after bullshit markets. The Starfall demo today is the latest proof point that reentry is becoming its own market. Space as a logistics domain is the natural next evolution of global cargo transportation. Sea → Air → Space 1/n🧵

Inversion was on Capitol Hill yesterday for the MACH-TB Congressional Reception and Showcase.   We’re proud to support the nation’s premier hypersonic test program that is making hypersonic flight testing faster, more frequent, and more affordable.   Arc is built for this mission.   Thank you to @KratosDefense for hosting yesterday’s reception and bringing together leaders from across government and industry.

On Memorial Day, we remember the brave Americans who gave everything to protect this land and the freedoms we share.   Their sacrifice will never be forgotten.

I'll be speaking at @tectonicdefense's Inside the Dome event on Thursday in DC about Space Based Interceptors alongside GDA leadership and other awesome companies. Space is no longer just a destination, but rather a platform whose core value is providing near-instant access to the entire world. If you're there, come and say hi! I’m hearing there are a few tickets still available. Link below

Inversion is partnering with @anduriltech to work on Space-Based Interceptors for Golden Dome. We are proud to support such a critical national security and technical challenge. x.com/anduriltech/st…

Inversion is proud to partner with Anduril on Space-Based Interceptors for Golden Dome. Anduril has set the standard for building real operational capability at speed and scale. @InversionSpace is thrilled to be building alongside them. Space offers access to the globe at unprecedented speeds. Advanced reentry lets that become physical, and will play a critical role in SBI. Work is already ripping.

No music. No voiceover. Just the ride. Hop onboard our Arc drop test vehicle as it tests our autonomous parachute system. After reentry from space, Arc deploys its parachutes and steers itself to a precise, soft landing. We conduct regular drop tests in California to refine our custom flight computer and onboard autonomy stack. Powered by AI, advanced GNC, and computer vision, Arc is designed to land within feet of its target – anywhere in the world.

Space will define the future. The 21st century so far has been about getting to space regularly. The next chapter, is about coming back.

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.
