Final answer:
Once it was anticipated that the atomic bomb would be ready, military leaders swiftly planned for its deployment, including identifying targets and informing key commanders.
Step-by-step explanation:
The military planning for the use of the atomic bomb accelerated once there was confidence in the weapon's imminent readiness. By the end of 1944, a list of possible targets in Japan was established, and specialized training was given to a B-29 squadron for the bomb's delivery. Major General Leslie R. Groves, leading the Manhattan Project, was responsible for briefing certain Pacific commanders about the advanced weapon.
