Executive Management Team
Chairman of the Board
Mark Cochran brings over 37 years of subject matter expertise in military and civil aviation and maritime operations, safety and training to the ATAC Board of Directors. He joined ATAC in 2002 as a senior military aviation analyst and was the Director of Military and Unmanned Aerial Vehicle Systems (UAS) Programs until retiring in December 2015. Mark became a member of the ATAC Board of Directors in November 2015, and was named Chairman of the Board in the same month.
At ATAC, Mark was responsible for expanding the use of the Naval Aviation Simulation Model (NASMOD) — which was originally developed to support Navy air training capacity analysis through modeling and simulation — to include complex regional range and airspace operations analysis, as well as environmental and range sustainment/encroachment analysis for all four Department of Defense service branches and foreign military partners. He also led ATAC’s entry into the UAS market through operations analysis work with the Department of Defense and then expanded ATAC’s UAS presence to the FAA with the UAS Test and Engineering Team at the William J. Hughes Technical Center in Atlantic City, New Jersey.
Prior to his work at ATAC, Mark spent 23 years in many leadership positions in the U.S. Navy. He directed a wide range of aviation operations and training in joint strategic Command, Control, and Communications (C3) missions, maritime patrol, and aircraft carrier and battlegroup safety and risk management. He has over 5,000 hours total flight time in the EC-130Q; EC-135J; E-6A; P-3C; A-6E; EA-6B; S-3B; and F-14D aircraft. Mark has a B.S. in Engineering from Arizona State University.
