The MTVs and MTGXs were the first to be modified as they are closest to the unified MTM standard with 3 cannons already though these weapons and other systems and equipment have also been upgraded. The ships are also receiving refurbishment and modifications to enable them to serve into the early 2120s when they are scheduled to receive a final refurb to take them to their early 2130s planned end-of-service dates. The 3 MTVs were the former VIP fleet of the HCS Space Navy, much of the former VIP suites had been removed and this process was completed as part of MTM. The extensive C3 suite has been retained however and has been upgraded and will become standard across the fleet.
