DeltaHawk was founded in 1996 by Doug & Diane Doers and John (JP) Brooks. Doug was an experienced military and civilian pilot and mechanical engineer, Diane had extensive business experience, and JP was an experienced military pilot and American Airlines Captain. Together, they had the vison to create a modern engine that was cleaner, more efficient, and required less maintenance along with bringing improved performance and higher reliability to General Aviation.
This highly ambitious project turned out to be substantially more difficult and much more costly than they imagined, but their stubborn perseverance drove them to continue towards their goal, long after most others would have given up. Through many years of dedicated effort, averaging only 2-3 employees, progress was slow, with lack of funding being the major impediment to both engine completion and achieving FAA Type Certification.
In 2015, Al and Chris Ruud became aware of DeltaHawk’s situation, so with their shared vision, dedication, perseverance and financial support the engine achieved FAA Type Certification in 2023.
Our campus, adjacent to Batten International Airport (KRAC) in Racine, Wisconsin, centralizes more than 85,000 square feet of facilities. Thanks to significant investment, we are able to design, assemble and test virtually every critical component of our engines in-house, allowing precise quality control throughout the build process. We operate state-of-the art facilities for engine and subsystems testing—including fuel and cooling systems, superchargers and propellers, along with ISO Class 8 clean rooms, installation kit development teams, fabrication and assembly capabilities, and flight test.
