The procedure and process for development, control, and maintenance is the same for ICDs and ISs. The EELV competition was expected to produce the next generation of launch vehicles to replace all medium to heavy launchers, Lockheed Martin's Atlas, Titan II and Titan IV series, and McDonnell Douglas's Delta series, with a single family of vehicles capable of launching medium and heavy payloads into orbit at a significantly lower cost. {!Kd#5:#[T$FhTs;*(Ai((4N|radRbt!BHx2eq(*xiTxa$m|+Id99uLA@(C!#Oro;{N4"#.
