U.S.-based Inversion Space has introduced the “Arc” spacecraft, capable of delivering cargo from low Earth orbit to the ground within hours, and notable for its reusable design in hypersonic testing. The company emphasizes that the system could revolutionize both military logistics and space R&D processes.
Delivery from Orbit in Hours
The newly developed Arc is designed as a reusable compact orbital return capsule. The vehicle has a payload capacity of approximately 500 pounds (225 kg) and can land at a designated location in less than an hour after departing from low Earth orbit.
With hypersonic reentry maneuvers, Arc achieves high-precision landing capability, designed to rapidly supply military units or disaster zones. During descent, parachute-based deceleration systems allow it to land on land or water without the need for a runway or sea platform.
Reusable Hypersonic Test Platform
Arc is not only intended for logistics but also serves as a reusable hypersonic test vehicle. Its heat shield and structural components have been validated in previous test flights to withstand high-speed and high-heat conditions.
This allows engineers to test thermal protection systems, sensors, coatings, and guidance algorithms on a reusable platform. Repeated flights significantly reduce both costs and development time.
A New Layer in Tactical Logistics
The Arc system stands out as a solution compatible with the U.S. Department of Defense’s “tactically responsive space” concept.
Through this system, a special forces team could quickly obtain critical supplies such as blood products, drones, communication modules, or counter-UAV systems in mountainous regions or along island chains.
Arc’s autonomous guidance software enables multiple deliveries to different targets within a single orbital pass.
Next-Generation Space Logistics
As the U.S., China, and Russia continue to compete in hypersonic and space-based systems, the Arc project aims to provide the Western alliance with speed, flexibility, and reusability.
If the system reaches official contracts following successful test flights, Arc could open a new era in orbital logistics support and hypersonic data collection capabilities.
