Michele Evans, who led Lockheed Martin’s Aeronautics business since 2018, died on Jan. 1 2021, the company announced Saturday. Evans took a leave of absence that began Dec. 1 2020 “to address health issues unrelated to the coronavirus pandemic,” according to a Securities and Exchange Commission filing by the company. She previously took medical leave in September 2019 due to a cancer diagnosis. Evans is in her current role since 2018 after serving as VP and general manager of integrated warfare and sensor systems.. She held positions of increasing responsibilities since 1987 at Lockheed, responsible for multiple platform programs including the A-10 weapons system, as well as avionics programs on the F-35, F-22, F-16 and C-130. She currently serves on the board of the Smiothsonian National Air and Space Museum. Before becoming vice president of the Aeronautics division, Evans held multiple executive positions in the company’s Rotary and Mission Systems business area, serving as vice president and general manager of integrated warfare systems and sensors as well as vice president for C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance). Earlier in her career, she managed avionics programs for the C-130 and F-35 aircraft. Evans spent 34 years working at Lockheed and, before her medical issues, was seen as a top contender to replace Marillyn Hewson as the company’s chief executive.
