MDEC in ASW duties is used to manage dynamic events and sinker-related tasks during a mission. In antisubmarine warfare, conditions and contacts can change rapidly, and the team needs a centralized way to log those developing events and coordinate any actions tied to the sinker equipment. This focused role makes MDEC the best fit, since weather updates, overall mission planning, and encryption are handled by other systems and aren’t the primary function of MDEC in this context.
