Ares V
That final redesign would have made the Ares V booster taller and more powerful than the now-retired Saturn V/INT-20, N-1, and Energia rockets, and would have allowed the Ares V to place both the Earth Departure Stage and Altair spacecraft into low-Earth orbit for later on-orbit assembly. Unlike the 5-segment SRB for the Ares I, the 5.5-segment boosters for the Ares V were to be identical in design, construction, and function to the current SRBs except for the extra segments. Like the shuttle boosters, the Ares V boosters would fly an almost-identical flight trajectory from launch to splashdown.
