Five F-1 engines powered the Saturn V's S-IC first stage, while five J-2 engines powered its S-II second stage, and one J-2 the S-IVB third stages. By 1965, Rocketdyne built the vast majority of United States rocket engines, excepting those of the Titan rocket (built by Aerojet), and its payroll had grown to 65,000.
A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of lifting payloads between 20,000 to 50,000 kg (44,000 to 110,000 lb) (by NASA classification) or between 20,000 to 100,000 kilograms (44,000 to 220,000 lb) (by Russian classification) [1] into low Earth orbit (LEO). [2]
