Liftoff Thrust: 79,769.00 kN. Total Mass: 6,363,000 kg. Core Diameter: 24.00 m. Total Length: 29.00 m. Development Cost $: 4,088.00 million. in 1964 average dollars. Launch Price $: 25.00 million. in 1964 price dollars. Cost comments: Reflight price -$ 25 per pound - after twenty flights. Bono expected the cost per flight to drop to $ 10 per pound ($ 10 million per flight) after 100 re-uses!.
