Turning space into a transportation layer for Earth
Business model breakdown
Buyer: who owns the budget?
UnverifiedGovernment defense and space agencies and prime contractors (DoD, NASA).
Trigger: what makes them buy now?
Need for rapid delivery to austere or denied environments, realistic hypersonic threat-trajectory test platforms, and Golden Dome interceptors.
Workflow: what inputs become what output?
Arc spacecraft are pre-positioned in LEO in constellations, then deorbit to deliver cargo to a precise landing point; also fly as hypersonic test targets or reusable satellites (up to 5 years on orbit).
Economics: what it saves and how it charges
UnverifiedContract revenue from government programs and partnerships (NASA aerocapture selection, Kratos MACH-TB 2.0 test program, Anduril partnership); vehicles are reusable to lower per-mission cost.
Distribution: how it reaches customers
UnverifiedDirect government and prime-contractor partnerships; no public self-serve path.
