In July 2001, Wynne was confirmed as Principal Deputy Under Secretary of Defense for Acquisition, Technology and Logistics, and in May 2003 he was appointed as acting Under Secretary of Defense for Acquisition, Technology and Logistics. In this role, Wynne was the principal staff assistant and adviser to the Secretary and Deputy Secretary of Defense for all matters relating to the Department of Defense Acquisition System, research and development, advanced technology, developmental test and evaluation, production, logistics, installation management, military construction, procurement, environmental security, and nuclear, chemical and biological matters. As Secretary of the Air Force he was responsible for the affairs of the
Department of the Air Force, including the organizing, training, equipping and providing for the welfare of its nearly 370,000 men and women on active duty, 180,000 members of the
Air National Guard and the
Air Force Reserve, 160,000 civilians, and their families.

Renewable energy Wynne is a prominent proponent of
renewable energy, and supported the Air Force's continued leadership in clean energy procurement. In an Air Force brochure on the topic, Wynne wrote: The reliance on imported oil continues to threaten the economic, financial and physical security of the nation while the use of domestic fossil fuels contributes to nationwide pollution problems. The Air Force believes that development of renewable energy sources for facility energy is one important element of our comprehensive strategy. The USAF is the nation's 16th leading user of electricity from renewables.
Non-lethal weapons on October 19, 2007. Wynne advocated testing nonlethal weapons, such as high-power microwave devices, against American citizens before being used on the battlefield, saying "If we're not willing to use it here against our fellow citizens, then we should not be willing to use it in a wartime situation [because] if I hit somebody with a nonlethal weapon and they claim that it injured them in a way that was not intended, I think that I would be vilified in the world press."
Resignation from the Department of the Air Force On June 5, 2008, Robert Gates announced that he had accepted the resignation of Michael Wynne as Secretary of the Air Force because of "a decline in the Air Force's nuclear mission focus and performance" and "lack of a critical self-assessment culture". Gates specifically cited two incidents in which the Air Force had lost track of nuclear weapons or parts; in one incident, nuclear weapons fuses had been mistakenly sent to Taiwan when helicopter batteries had been ordered, and in the other, the
2007 United States Air Force nuclear weapons incident, a B-52 bomber had been flown across the country armed with six nuclear-armed cruise missiles that no one realized were on board. Wynne responded that the report on the event was colored by the cultural differences of the Navy admiral,
Kirkland H. Donald, who prepared it.
Later service In June 2020, President
Donald Trump announced Wynne's appointment to the Board of Visitors of the United States Air Force Academy. Wynne was later asked by President Joe Biden to resign in September 2021. ==Writing==
