Pioneering the next era of aerospace through six years of extensive research, testing, and development.
Dave Merrill and Clint Cope found Elroy Air in San Francisco, CA.
In November 2017, we marked our first full year of operations. In the first 12 months, we formed a small expert team of aerospace and drone engineers who designed, built and operated our earliest softwre builds and electric propulsion testing in a hardware incubator space in San Francisco, taking input from our pioneering customers in commercial, humanitarian, and defense shipping.
In 2018, we were invited participants at multiple Joint Interagency Field Experimentation (JIFX) events at Camp Roberts, CA where we flight-tested sub-scale Chaparral aircraft and user-tested our automated cargo‑handling systems. Our development of a NASA-inspired propulsion test stand enabled full characterization of electric powertrain elements — motors, rotors, and motor controllers — running testing activities at the Half‑Moon Bay airport.
In 2019, we started working with the US Air Force under a Phase 2
Further build-out of our simulation environment enabled the team
to run thousands of virtual flights and ground/cargo mission
experiments took place in 2020. Development of our hybrid-electric
powertrain began, with a series of turboshaft engine runs in the
small yard outside our headquarters in the industrial Dogpatch
neighborhood of San Francisco. We joined the US Air Force Agility
Prime program and started a Phase 3
A $40M Series A financing in 2021 made Marlinspike, Lockheed Martin, and Prosperity7 part of the Elroy Air team and powered full fuel-to-electric runs of Chaparral’s hybrid-electric powertrain. We received the first C1 airframe from our composite production partner, and began integration of the C1-1 vehicle.
An additional $36M in financing from Shield Capital,
Marlinspike, Snowpoint, and others powered our unveiling of the
C1-1 Chaparral vehicle to the public, followed soon after by our
appearance as the cover story of Aviation Week. We announced
commercial partnerships with FedEx and Bristow, we were awarded
Elroy Air soared to new heights in 2023 with the first flight of the
Chaparral C1, making history by flying the world’s first
turbogenerator-hybrid VTOL aircraft. Beyond this momentous
achievement, we secured deposits for vehicle sales with LCI and
Bristow, started a new
