The Marconi EW / Elint fleet will receive upgrades in their long-range sensors among other updates to improve their intelligence gathering and processing capabilities. The Marconi ships will receive new radio receivers, improved computers and better crew facilities to allow for a larger complement of intelligence officers. Communications facilities will also be upgraded to allow for more data to be sent to planetary bases for further processing.
The Orchid has stated that the DDS must greatly improve it's intelligence gathering processes as part of the new proactive policy. These Marconi updates will just be a part of that.
