U.S. Built UAS

Who We Are

We are a small but dedicated team of UAS engineers and operators making American built drones systems accessible and useful for those that need them most. We are fully U.S. based and proudly build all of our aircraft just north of Purdue University, where the founding team met, and where Uniform Sierra Aerospace started.

The Founding Team

  • Duncan Mulgrew

    CO-FOUNDER and CEO

    Duncan has been building and flying sUAS for close to 10 years and has accumulated over 2,500 remote flight hours spread over hundreds of systems. He has built over 100 unique aircraft and operated them around the country. Duncan has experience working with Military, Government, and Industry groups on different UAS based projects and research. Before founding Uniform Sierra with Jeremy Frederick he designed and built custom sUAS systems for a range of clients, and raced FPV drones competitively.

  • Trevor Redpath

    COO

    Trevor has a bachelors in Unmanned Aerial Systems from Purdue University. From his time at Purdue he has discovered his passion for aircraft and unmanned systems. This has led to him getting his FAA Part 107 and participating in research projects and a class sponsored by the Air Force Research lab. Outside of research and work Trevor has built a variety of aircraft from race wings to micro quads and is comfortable with most commercially available UAS.

I can’t speak highly enough to Uniform Sierra’s customer service and professionalism, with the growing number of time critical and high stress missions rising, there is no one else I want in my corner than this team out of Indiana.
