Lieutenant General Frank Maxwell Andrews was a senior officer of the United States Army and one of the founders of the United States Army Air Forces, which was later to become the United States Air Force. In leadership positions within the Army Air Corps, he succeeded in advancing progress toward a separate and independent Air Force where predecessors and allies such as Billy Mitchell had failed. Andrews was the first head of a centralized American air force and the first air officer to serve on the Army's general staff. In early 1943, he took the place of General Dwight D. Eisenhower as commander of all U.S. troops in the European Theater of Operations.

In the United States Armed Forces, a lieutenant general is a three-star general officer in the United States Army, Marine Corps, Air Force, and Space Force.
