Gulfstream Aerospace is expanding its senior leadership team to meet a growing number of aircraft programs and manage worldwide supply, the company announced today. Thus, it is promoting vice president of flight operations Colin Miller to senior vice president of innovation, engineering and flight, and vice president of initial and final phase manufacturing Greg Collett to senior vice president of manufacturing and completions.

Miller will be taking the baton from Dan Nale, who will retire April 1 after nearly 35 years at Gulfstream, the past six of which has seen him at the helm of innovation, engineering, and flight. Miller joined Gulfstream in 2013 as an experimental test pilot and has since been a part of the development, testing, and certification programs for the G500 and G600, as well as the development of advanced aircraft technologies.

In his new role, Collett is assuming some of the responsibilities held by senior vice president of operations Dennis Stuligross, who is simultaneously being elevated to senior vice president of program management, quality, and supply chain. Since joining Gulfstream in 1998, Collett has held various leadership roles in operations, including oversight of initial and final phase manufacturing, new product development, and manufacturing operations.
