The Noggra class is a heavy transport cruiser built by the Klingons originally to ferry warriors to sites of battle and honor. Following several years of heavy use on several campaigns, the Noggras left the Klingon Defense Forces feeling that they were inadequate for the mission at hand. The Noggras were simply too expensive and too maintenance intensive to keep in service as troop transports.

The Noggra Transport Cruisers were all sold off to members of the houses, many of which took to using them as executive transports, ferrying in luxury from Qo'Nos to other areas of the Empire and beyond. In this role they continue to serve.
