The final 2 Molentic Tuul M conversions have been completed ahead of schedule giving the HCS a unified fleet of 21 MTMs instead of the split fleets of MTAs, MTGXs and MTVs they had before. A HCS spokesclone said it would make upgrading and maintaining the fleet easier and cheaper in future.
Indeed an upgrade to the MTM fleet is to take place in the new year to standardise all of the ships (later ones having later versions of some systems) and to add passive sensors and an improved main databus.
