With its moonwalks, deployment of a geophysical station and geological sampling, Apollo 12 did what many had was hoping will be completed via the 1st males to land at the Moon. It spectacularly verified the precision touchdown potential required for the luck of destiny lunar floor explorations.

The thrust structure was an inverted cone which narrowed to a diameter of 18 feet for the five J-2 hydrogen-burning engines. As with the S-IC, the inboard engine was fixed on the axis and the outboard engines were hydraulically gimballed for thrust vector control to steer the vehicle. Because the propellant tanks of the S-II had a common bulkhead there were domical caps only at the bottom of the oxidiser tank and top of the fuel tank. The integrated tanks were 78 feet tall. If a conventional arrangement had been employed, the additional end caps would have made the stage some 10 feet longer and 8,000 pounds heavier, taking it beyond its specifications.

Soon after S-IC-7 was installed on the B-2 stand in September, the motor of the derrick had developed a fault. As a result, the stage could not be removed until this was fixed - which would require a component to be specifically manufactured. The repair was finished on 8 November and the stage was loaded onto a barge later that day. After arriving at the Michoud Assembly Facility on 9 November the stage was refurbished. A simulated flight on 20 January 1969 drew the post-static checkout to a successful conclusion.
