Watson had a personal interest in the progress of the war. His eldest son, Thomas J. Watson Jr., joined the [[United States Army Air Corps]] and became a bomber pilot. He was soon hand-picked to become the assistant and personal pilot for General Follet Bradley, who was in charge of all [[Lend-Lease]] equipment supplied to the Soviet Union from the United States. Watson Sr.'s youngest son, [[Arthur K. Watson]], also joined the military during the conflict.{{Cn|date=April 2025}}
