WASHINGTON — Lockheed Martin announced Aug. 22 the appointment of Michele Evans as executive vice president for aeronautics, with oversight over the world’s largest defense company’s aviation portfolio.

Evans, currently the deputy in the aeronautics unit, will take over Oct. 1 following the retirement of Orlando Carvalho, who has held that job since 2013.

Evans has served in a number of roles during her 31 years at Lockheed Martin. In the last eight years, she has served as vice president for business development and strategy mission systems and training; vice president/general manager of the company’s C4ISR/undersea systems business line; and vice president/general manager for integrated warfare and sensor systems.

In those roles she had a direct hand in several major programs for the company, including the littoral combat ship.

“Michele has led critical elements of our business, building an impressive record of leadership and strong customer relationships around the globe,” Lockheed Martin CEO Marillyn Hewson said in a statement. “Her appointment demonstrates the importance of our talent development and succession planning.”

Lockheed remains the world’s premiere defense contractor, thanks in part to its dominance in military aviation programs.
