About Hop Aero

Hop Aero is a US aerospace and defence startup building autonomous rocket cargo vehicles that deliver payloads to distant, austere and contested locations in minutes. Its rockets fly point-to-point at hypersonic speeds, launching from standard infrastructure and landing on unprepared surfaces without runways. The company's flagship vehicle, Rook, is an autonomous hypersonic cargo rocket designed to deliver up to 550 lbs across roughly 450 miles in about 15 minutes, launched from a standard 40-foot shipping container. Founded in 2024 and based in Orange County, California, Hop Aero is part of Y Combinator's Summer 2026 batch and targets defence and rapid-logistics applications for the US and allied forces.
