The Marconi 81A EW / special forces support ships are important though use very little of the SUP vast bulk available. Even fully loaded with NS Marines and support systems (and the usual EW/Elint modules) a Marconi will only be using about twenty percent of it's internal space!
The three ships in service will receive an upgrade over the next few months called Marconi Capability Upgrade 2123A. The Marconis will be fitted with cargo handling equipment and fitted out holds enabling them to be used to carry transport as an auxiliary role. They will also receive a tactical upgrade, giving them TPM-3 support and communication updates.
