"We need a real person who embodies America's greatest values. We need someone to inspire us again, someone who can be a symbol for all of us. So, on behalf of the Department of Defense and our Commander-in-Chief, it is with great honor that we announce here today that the United States of America has a new hero. Join me in welcoming your new Captain America."
―Military Man[src]

The United States Department of Defense, occasionally referred as DOD, is an executive branch department of the United States of America.

Beneath it are many subordinate departments, including the Departments of the Army, Navy, and Air Force, the Defense Advanced Research Projects Agency, the National Security Agency, and the National Reconnaissance Office.


Project Helius

In the 1950s, Department of Defense appointed Gerald Sharpe to work with S.H.I.E.L.D. and oversee the Project Helius, although he came to the conclusion that the project was pointless since there was no possible power source for the Ion Fusion Reactor.[1]

Romanoff's Testimony

In 2014, Natasha Romanoff attended a Department of Defense committee meeting that included S. Scudder, P. Wenham, C. Bryant, and J. Sandell. Wenham wanted her imprisoned for the crimes she had committed in her past, but ultimately did not get his way.[2]

New Captain America

In 2024, following Sam Wilson's donation of Captain America's Shield to the Smithsonian Institution, the Department of Defense gave the shield to Captain John Walker for him to become the "new Captain America". This decision was approved by the President of the United States and top-ranking members of the Department of Defense.[3]
