Michael Wynne

Michael Wynne died on 17 October 2026 in Melbourne, Florida, the town where he grew up. He was 82. The cause of death has not been made public. His death was reported by Air and Space Forces Magazine on 22 October, and the West Point Association of Graduates recorded that he would be interred at Arlington National Cemetery.

General Moseley described their working relationship as a privilege and a gift, and Lieutenant General David Deptula called him a leader of uncommon integrity, genuine kindness and extraordinary loyalty. He was survived by his wife, Barbara, and their four daughters.

Michael Walter Wynne was born on 4 September 1944 in Clearwater, Florida, and was raised in Melbourne, Florida. He came from a military family and followed his father to the United States Military Academy at West Point, graduating in 1966 with a Bachelor of Science in general engineering. Of his 578 classmates, 30 died in Vietnam.

His older brother, Patrick Edward Wynne, a 1963 graduate of the Air Force Academy, flew F-4C Phantoms with the 555th Tactical Fighter Squadron. He was shot down over Vietnam on 8 August 1966 and listed as missing in action; his remains were returned in 1977 and are buried at the Air Force Academy. Wynne later recalled that the report of his brother being shot down was announced on the day he reported for active duty. He went on to earn a master's degree in electrical engineering from the Air Force Institute of Technology in 1970 and an MBA from the University of Colorado, Colorado Springs, in 1975.

Wynne chose the Air Force over the Army and served from 1966 to 1973, finishing as a captain and assistant professor of astronautics at the Air Force Academy.

After two years with Research Analysis and Development, Inc., he joined General Dynamics in 1975 and spent a total of 23 years there in senior roles with the Aircraft (F-16) and Main Battle Tank (M1A2) divisions and on the corporate staff, becoming a corporate vice president and president of Space Systems, which built the Atlas and Centaur launch vehicles. When that division was sold to Martin Marietta in 1994 he became general manager of Space Launch Systems at what became Lockheed Martin Astronautics, combining the Titan and Atlas programmes. He rejoined General Dynamics in 1997 as senior vice president for international development and strategy, retiring in 1999. He then worked in venture capital with the NextGenFund and was chairman and chief executive of the travel technology company IXATA Group.

In July 2001 he was confirmed as Principal Deputy Under Secretary of Defense for Acquisition, Technology and Logistics under Donald Rumsfeld. He was acting Under Secretary from May 2003 and was confirmed in the post in 2005, leading preparations for the 2005 Base Realignment and Closure round.

He became Secretary of the Air Force on 3 November 2005, responsible for nearly 370,000 active duty airmen, 180,000 Guard and Reserve members and 160,000 civilians, with a budget of about 110 billion dollars. He fought to protect the F-22 Raptor, pressed for a new tanker and a future bomber, opposed joint basing, highlighted the air component of the 2007 Iraq surge, and promoted renewable energy, making the Air Force one of the largest users of renewable electricity in the country. He drew criticism for suggesting non lethal weapons should be tested at home before being used in war.

On 5 June 2008 Robert Gates announced he had accepted the resignations of Wynne and General Moseley, citing a decline in the Air Force's nuclear mission focus after the August 2007 Minot to Barksdale B-52 incident and the mistaken shipment of Minuteman missile fuses to Taiwan. Wynne argued that Admiral Kirkland Donald's report reflected the cultural differences of a Navy officer. He left office on 20 June 2008 at a ceremony at which Gates presented him with a medal. In 2020 he was appointed to the Air Force Academy Board of Visitors, and in 2021 he was asked to step down.

Wynne was married to Barbara Wynne, and they had four daughters. He published numerous professional journal articles on engineering, cost estimating and contracting, and was a fellow of the National Contract Management Association. His former colleague Robbin Laird summed up his outlook in what he called the Wynne Doctrine: if you are ever involved in a fair fight, it is the result of poor planning.

Wynne is remembered as an engineer and acquisition specialist who argued for long term modernisation, including the programmes that became the KC-46 tanker and the B-21 bomber, and as the secretary whose dismissal with Moseley in 2008 led to sweeping reforms of how the Air Force manages nuclear weapons. Former aides recalled his loyalty to the people who worked for him.
