A Los Angeles-based startup has unveiled Arc, a reusable orbital spacecraft designed to deliver cargo anywhere on Earth in under one hour. The company aims to revolutionize logistics for both military and humanitarian missions while creating a new global transportation layer.
Here’s what makes this technology unlike anything that has come before.
What’s Going On?
Arc promises to redefine delivery speed with Mach 20+ hypersonic capabilities. It can transport up to 500 pounds to almost any location on Earth, completing missions previously requiring hours in under 60 minutes.
The spacecraft combines advanced avionics, reusable design, and autonomous systems. But how did this ambitious project come to life?
Who’s Behind Arc?
Inversion Space was founded by Justin Fiaschetti, a former SpaceX propulsion engineer, and Austin Briggs, an early engineer at ABL Space Systems. Both bring decades of aerospace experience, leading a 60-person team from their 55,000-square-foot Los Angeles facility and Mojave Desert test site.
The startup also collaborates with NASA and the U.S. Space Force for specialized expertise.
Key Partners and Backers
Inversion’s growth relies on government and industry support. NASA provides thermal protection expertise, Kratos Defense leads hypersonic testing, and SpaceWERX awarded a $71 million STRATFI contract. Investors include Y Combinator, Lockheed Martin Ventures, and Spark Capital.
This support ensures both financial stability and access to critical aerospace infrastructure.
What Is the Arc Spacecraft?
Arc is a lifting-body, reusable spacecraft roughly 8 feet tall and 4 feet wide. Its payload bay is designed for diverse missions, carrying cargo with high precision across global distances.
Its versatility allows Arc to operate for military, humanitarian, and commercial missions. But what can it actually achieve?
Arc’s Speed and Precision
Arc achieves hypersonic speeds over 15,000 mph, reaching targets anywhere on Earth in under an hour. Cross-range capability spans 621 miles, allowing for accurate landings within 15–50 feet, regardless of terrain.
This precision is supported by autonomous parachute landings and non-toxic propellants, ensuring immediate safe handling of cargo.
Dual-Purpose Capabilities
Beyond cargo delivery, Arc functions as a hypersonic test platform. It replicates next-generation threat trajectories, sustains high g-loads, and allows prolonged testing during Mach 20+ flight.
This dual-use approach strengthens U.S. defense research while enhancing operational utility for future logistics networks.
How Arc Came To Be
Arc builds on the Ray spacecraft, launched in January this year. Ray validated avionics, propulsion, and separation systems, despite a short-circuit in the deorbit engine, proving Inversion’s ability to develop advanced, cost-effective spacecraft.
This heritage guided Arc’s design for reusability, precision, and rapid deployment.
When Will Arc Fly?
Arc’s first orbital flight is scheduled for 2026, with full operational constellation deployment targeted for 2028. The goal is hundreds of Arc spacecraft per year, creating a global on-demand logistics network.
Early drop tests and aerodynamic modeling are already complete, bringing Arc closer to reality.
Regulatory Hurdles Ahead
Arc still requires FAA certification for reentry operations and landing procedures. Hypersonic navigation must be refined, and high-frequency launch and recovery processes need scaling to match operational goals.
These steps are critical to ensuring safe, routine, and reliable global operations.
Why Arc Matters for Military Logistics
Traditional C-17 airlift can take 10–15 hours. Arc delivers the same payload in under one hour, reducing transit time by roughly 90%.
This speed allows forward brigades, isolated naval units, and disaster-response teams to receive critical supplies faster than ever.
Humanitarian Applications
Arc could deliver emergency medical supplies, vaccines, food, and water to disaster-struck or isolated regions. Its precision landing in infrastructure-limited areas ensures aid reaches those in need quickly.
Rapid delivery in crises could save lives and reshape disaster-response strategies globally.
Commercial Potential Beyond Defense
Inversion envisions Arc supporting global commerce. Faster logistics enable small businesses in remote regions, medical supply chains, and even consumer shipments to benefit from orbital delivery.
CEO Justin Fiaschetti emphasizes that space can provide universal access to Earth, creating new markets and opportunities.
How Arc Operates
Arc is pre-positioned in low-Earth orbit for immediate activation. Upon command, it autonomously deorbits, executes hypersonic maneuvers, and lands via steerable parachutes.
This “warehouse in space” concept reduces reliance on traditional transportation and enables delivery to almost any terrain.
Technical Innovations
Arc’s lifting-body design allows active steering, controlled descent, and landing on water, snow, or ground. NASA-provided heatshields ensure safety during Mach 20+ reentry.
These innovations enable Arc to deliver cargo precisely, safely, and reliably, surpassing conventional aerospace capabilities.
Propulsion and Subsystems
Arc incorporates autonomous guidance, deorbit propulsion, solar panels for long-term power, thermal management, and reliable separation mechanisms. Each system has been validated through prior missions.
This integration ensures robust performance and mission flexibility, even under extreme conditions.
Cost Efficiency Model
Arc’s reusability and in-house production reduce costs. Ray demonstrated a 200-pound spacecraft could be built for under $1 million. Arc, though larger, leverages similar manufacturing efficiency.
These methods allow scaling to hundreds of units annually without traditional aerospace expenses.
Constellation Strategy
Arc’s global reach depends on overlapping orbital constellations. Initial deployments target strategic regions, eventually expanding to thousands of spacecraft for <1-hour delivery worldwide.
Careful orbital mechanics ensure some Arc spacecraft can always reach any target location within the promised timeframe.
Global Reach and Impact
Arc’s 621-mile cross-range ensures near-global coverage. New York to Philadelphia, Los Angeles to San Francisco, and London to Berlin are achievable in one flight. Traveling from Tokyo to Seoul may require multiple flights or spacecraft.
This establishes an unprecedented logistics layer connecting isolated regions, military units, and humanitarian efforts.
The Future of Logistics
Inversion Space’s Arc demonstrates how orbital transport can transform global delivery. Its hypersonic speed, precision, and dual-use capabilities create a new dimension in logistics.
From disaster response to defense and commerce, Arc sets the stage for a world where one-hour global connectivity becomes a reality.
