Nat Geo Provides Unprecedented View of New Air Force VC-25B “Air Force One”. Nat Geo Provides Unprecedented View of New Air Force VC-25B “Air Force One”. Never Before Seen Video Showcases Development of New “Air Force One”: Boeing 747-8 as VC-25B. It is hidden behind what may be the tightest security screen on earth. It is the most visible mobile projection of the United States. The U.S. Air Force Boeing VC-25A heavy transport most commonly known as “Air Force One” (for its call sign when the President is on board) is perhaps the most recognizable military aircraft in the world. This contradiction between projecting visibility while maintaining security is one of the most difficult tactical problems to moderate for any security force in the world. The 30-year old Boeing VC-25A aircraft are currently being replaced by a new version of the Boeing 747-8 aircraft designated the “VC-25B”.
