Elroy Air develops autonomous vertical takeoff and landing (VTOL) cargo aircraft for defense, commercial, and rapid-response logistics. Its flagship Chaparral is a hybrid-electric aircraft designed to carry up to 300 pounds of cargo across roughly 300 miles with no crew onboard, taking off and landing vertically and cruising autonomously between points. Founded in 2016 and based in San Francisco, the company works with partners including FedEx, NASA, the U.S. Air Force, and Lockheed Martin, and was selected for the U.S. Department of Transportation eVTOL Integration Pilot Program. Elroy Air is a hardware and autonomy company; it does not currently publish a public developer API, OpenAPI, SDKs, or MCP surface. This profile was added to the API Evangelist network as a portfolio lead and enriched with identity and domain-security data.
