Yakushima Island. At the mission pre-briefing, the three planes were ordered to make their rendezvous over Yakushima at due to weather conditions over

(the Hiroshima mission rendezvous). That same morning, on the day of the mission, the ground crew notified Sweeney that a faulty fuel transfer pump made it impossible to utilize some of fuel in the tail, but Sweeney, as aircraft commander, elected to proceed with the mission.
Before takeoff, Tibbets warned Sweeney that he had lost at least 45 minutes of flying time because of the fuel pump problem, and to take no more than fifteen minutes at the rendezvous before proceeding directly to the primary target.
After takeoff from Tinian, ''Bockscar'' reached its rendezvous point and after circling for an extended period, found ''The Great Artiste'', but not ''The Big Stink''. Climbing to 30,000 feet, the assigned rendezvous altitude, both aircraft slowly circled Yakushima Island. Though Sweeney had been ordered not to wait at the rendezvous for the other aircraft longer than fifteen minutes before proceeding to the primary target, Sweeney continued to wait for ''The Big Stink'', perhaps at the urging of Commander
Frederick Ashworth, the plane's weaponeer. After exceeding the original rendezvous time limit by a half-hour, ''Bockscar'', accompanied by ''The Great Artiste'', proceeded to the primary target,

. No fewer than three bomb runs were made, but the delay at the rendezvous had resulted in 7/10ths cloud cover over the primary target, and the bombardier was unable to drop. By the time of the third bomb run, Japanese antiaircraft fire was getting close, and Japanese fighter planes could be seen climbing to intercept ''Bockscar''.

Poor bombing visibility and an increasingly critical fuel shortage eventually forced ''Bockscar'' to divert from Kokura and attack the secondary target, Nagasaki. As they approached Nagasaki, the heart of the city's downtown was covered by dense cloud, and Sweeney and Ashworth, initially decided to bomb Nagasaki using radar. However, a small opening in the clouds allowed ''Bockscar's'' bombardier to verify the target as Nagasaki. The crew had been ordered to drop the bomb visually if possible; Sweeney decided to proceed with a visual bomb run. ''Bockscar'' then dropped ''Fat Man'', with a blast yield equivalent to 21 kilotons of

. It exploded 43 seconds later at above the ground, at least northwest of the planned aim point. The failure to drop ''Fat Man'' at the precise bomb aim point caused the atomic blast to be confined to the Urakami Valley. As a consequence, a major portion of the city was protected by the intervening hills, and around 30% of Nagasaki was destroyed. The bombing also severed the Mitsubishi arms production extensively and killed an estimated 35,000–40,000 people outright, including 23,200–28,200 Japanese industrial workers, 2,000 Korean slave laborers, and 150 Japanese soldiers.
Low on fuel, ''Bockscar'' barely made it to the runway on Okinawa. With only enough fuel for one landing attempt, Sweeney brought ''Bockscar'' in fast and hard, ordering every available distress flare on board to be fired as he did so. The number two engine died from

With both pilots standing on the brakes, Sweeney made a swerving 90-degree turn at the end of the runway to avoid going over the cliff into the ocean. 2nd Lt.
Jacob Beser recalled that at this point, two engines had died from the fuel starvation, while "the centrifugal force resulting from the turn was almost enough to put us through the side of the airplane."
After ''Bockscar'' returned to Tinian, Tibbets recorded that he was faced with the dilemma of considering “if any action should be taken against the airplane commander, Charles Sweeney, for failure to command.”

'' and was seen explaining the USAAF buildup to the mission raids.
Throughout his life Sweeney remained convinced of the appropriateness and necessity of the bombing. "I saw these beautiful young men who were being slaughtered by an evil, evil military force," he said in 1995. "There's no question in my mind that President Truman made the right decision." At the same time, he said, "As the man who commanded the last atomic mission, I pray that I retain that singular distinction."
Later life
Near the end of his life, Sweeney wrote a controversial and factually disputed memoir of the atomic bombing and the 509th Composite Group, ''War's End: An Eyewitness Account of America's Last Atomic Mission''. In ''War's End'', Sweeney defended the decision to drop the atomic bomb in light of subsequent historical questioning. However, it was Sweeney's other assertions regarding the Nagasaki atomic mission, along with various anecdotes regarding the 509th and its crews that drew the most criticism.

and others vigorously disputed Sweeney's account of events. Partly in response to ''War's End'', Tibbets issued a revised version of his own autobiography in 1998, adding a new section on the Nagasaki attack in which he harshly criticized Sweeney's actions during the mission.
