O= Operational
OR= Operational after Refit or Repairs
DD= In Drydock for repairs or refit *
T= Training Vessel
U= Under construction prior to preliminary trials

*A ship would visit drydock for many reasons, including refits, repairs, servicing upgrades, preliminary trials and testing of new components, and spacedock for similar reasons, as well as crew rotation, reassignment, prep period before redeployment, and so forth.

As this class is only of my own speculation, all specs and stats appearing here are hypothetical. The explanations about this data, such as ship designations, weapons, offensive power etc, see Spec Definitions.
