Did the U.S Have a Third Atomic Bomb?
The use of atomic bombs by the United States against Japan in 1945 is one of the most significant events in modern history. The bombing of Hiroshima and Nagasaki led to Japan’s surrender and the end of World War II. But did the U.S. have a third atomic bomb ready to use?

Background
In the years leading up to the development of the atomic bomb, the United States had been racing against Germany to develop a nuclear weapon. After the German surrender in May 1945, the U.S. turned its attention to Japan, which had refused to surrender despite the Allied forces’ advancement.
In July 1945, the U.S. dropped atomic bombs on Hiroshima and Nagasaki, killing hundreds of thousands of people and leading to Japan’s surrender. The bombings were carried out by the 509th Composite Group, a unit of the U.S. Army Air Forces, using B-29 bombers.
The Third Bomb
The question of whether the U.S. had a third atomic bomb ready to use is a matter of debate. Some historians and researchers claim that the U.S. had a third bomb prepared and ready to drop, while others argue that the bomb was not ready and would not have been used.
Arguments for a Third Bomb
- Some historians point to a letter written by General Leslie Groves, the director of the Manhattan Project, to President Harry Truman in August 1945. In the letter, Groves mentions that a third bomb was available and could be used if necessary.
- Another argument is that the U.S. had a stockpile of fissile material, including uranium-235 and plutonium-239, which could have been used to build a third bomb.
- Some researchers claim that the U.S. had a third bomb that was designed to be dropped on Kyoto, a city in western Japan that was not targeted in the initial bombings.
Arguments Against a Third Bomb
- Many historians and researchers argue that the U.S. did not have a third bomb ready to use. They point to a lack of documentation and testimony from key figures involved in the Manhattan Project.
- General Curtis LeMay, the commander of the U.S. Army Air Forces, testified in the 1960s that there was no third bomb ready to use. He stated that the U.S. had only two bombs and that they were dropped on Hiroshima and Nagasaki.
- Some argue that the U.S. had already achieved its military objective with the bombing of Nagasaki, and that a third bomb would not have added significant military value.
Conclusion
The question of whether the U.S. had a third atomic bomb ready to use remains unclear. While some historians and researchers argue that the bomb was available and could have been used, others dispute this claim.
Summary of the Debate
| Argument | Proponents | Opponents |
|---|---|---|
| A third bomb was available and could have been used | General Leslie Groves, some historians and researchers | General Curtis LeMay, many historians and researchers |
| The U.S. had a stockpile of fissile material | Some researchers | No documentation or testimony to support this claim |
| Kyoto was the target of the third bomb | Some researchers | No documentation or testimony to support this claim |
Implications
Regardless of whether the U.S. had a third atomic bomb ready to use, the bombings of Hiroshima and Nagasaki had a profound impact on the course of history. The bombings led to Japan’s surrender and the end of World War II, but they also had a lasting impact on the development of nuclear weapons and international relations.
In the years following the bombings, the U.S. and the Soviet Union began a nuclear arms race, leading to the development of thousands of nuclear weapons and the threat of global catastrophe. The bombings also led to the development of international treaties and agreements aimed at preventing the use of nuclear weapons, such as the Nuclear Non-Proliferation Treaty and the Intermediate-Range Nuclear Forces Treaty.
Conclusion
The debate over whether the U.S. had a third atomic bomb ready to use in 1945 is a complex and contentious issue. While some historians and researchers argue that the bomb was available and could have been used, others dispute this claim. Regardless of the outcome, the bombings of Hiroshima and Nagasaki remain one of the most significant events in modern history, and their impact continues to shape international relations and the development of nuclear weapons to this day.
