The Delta Class was in parallel development to the Excelsior Class throughout the early 2270's. Transwarp though was never seriously considered for test trials in the Delta Class, and in many respects, Delta was produced as a back-up contingency for Starfleet to have an advanced Heavy Cruiser in service if the hugely ambitious Excelsior were to be a grand failure. As it was, fleet wide transwarp systems were not implemented as the Excelsior prototype failed to produce satisfactory progress in refining the technology. Over the next two years, The Excelsior and her few sister vessels at that time were installed with conventional warp engines, and as back up Delta Class took over frontier exploration and defence in their absence. But it was in the last few years of the 23rd century that Excelsior Class surpassed expectations and became obviously the superior Heavy Cruiser, and it continued production and upgrades at Delta's expense. The final Delta Class vessel, the Montenegro was commissioned in April 2295.

KEY

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
D= Destroyed
Sc= Scrapped or Decommissioned
PD= Presumed Destroyed
M= Missing

*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.
