For when you need cargo or effects, and you need it NOW So excited to share a sliver of the vision we’ve been quietly building. Arc is a real game changer for the US and the world.

Continuing to dial in the precision of our autonomous parachute landing system. @InversionSpace

Lifting body reentry Will be back Very soon @InversionSpace

@InversionSpace @jcfiaschetti Commercial launch cadence could compress hypersonic development cycles from decades to mere years.

RT @Cadillac_F1: Progress under pressure. The first Cadillac F1 livery is here.

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.

The US shouldn’t be looking to catch up to China in hypersonics technology, we should leapfrog them. Our investments need to flow to actually scalable approaches to testing: commercial space.

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.

@danpiemont People will refer to this tweet when the US finally shows the effectiveness of what you’re saying

There is a way for the Navy to get a lot of BMD equipped ships quickly and it doesn’t involve new shipbuilding

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.

@heatloss1986 Imagine if AFLCMC put the same requirements onto UAVs as they do planes. These systems are too tactical and we don’t want to add bureaucracy to stifle innovation. Until we have USVs and UUVs that carry the same scale of missions, just as CCA is, keep them out of the bureaucracy.

Can someone explain to me politely why this is important for USVs and UUVs but not for anything else? In detail. And no "well shipbuilding is a mess and I blame ChENG for it."

ARRW not only making the anticipated reappearance, but also getting a 60% budget increase

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.

Help guys I'm kinda getting into this extremely dual-use Arc concept

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 🇺🇸

@_abriggs and I are spending a lot of energy on the hundreds of small features and decision that role up to make Arc an amazing product for our customers.

Arc Orbital Supply Capsule Aims To Put Military Supplies Anywhere On Earth Within An Hour Deorbiting small cargo-laden spacecraft on-demand to troops in need is the vision of Inversion Space and its Arc spacecraft. Story: twz.com/space/arc-orbi…

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.
