Figure 1-1. Soyuz evolution. The light gray arrows trace the evolution of flown spacecraft. The dark gray arrows show influence of concepts and flown spacecraft on other concepts and flown spacecraft. Broad black lines enclose distinct programs. The stippled and light gray arrows pointing downward, off the chart, connect to the Space Station chart (figure 2-1) and the Station Modules and Tug Programs chart (figure 3-1), respectively.
