The famous Pioneer Class was how it all began for the new Federation Starfleet. First launched on May 13th 2161, the USS Pioneer and five other accompanying vessels left spacedock and set off to supplement and provision colonists already installed by the older Earth Starfleet vessels across a group of 16 stars close to Sol. Most of Sol's closest stellar neighbours had been scouted and surveyed over the past fifty years with sub light-speed probes, and several colonizing expeditions had already embarked into the great unknown. The NX Class explorers played key roles in these assignments. Over the next five years though, Starfleet would chart and explore the thousand most closest star systems to Earth. Starship design complexes such as San Francisco Fleet Yards were being constructed in similar locations at the newly aligned worlds, such as Vulcan, Andoria and Tellar. This soon allowed an ever expanding net of starships with which to explorer the Alpha Quadrant, and within 200 years, nearly 40% of the entire quadrant had been charted and explored...

-I think it's odd that such a classic name as 'Enterprise' wasn't used again for a starship until the Constitutions came along in the 2240's, a full eighty years after the Federation was founded. Even though now we know there will be a pre-Federation cruiser called Enterprise (from the new series 'Enterprise'), we know for sure there was no Federation ship called Enterprise until Constitution due to many remarks along the lines that Enterprise-D was the fifth to bear the name, and Enterprise-E was the sixth, and so forth. But I really think there should be an early ship named Enterprise, but I can't break canon, so I've been inventive, naming certain ships for the new Federation fleet, -which was at the height of a renaissance period on Earth-, 'New Frontier', 'New Horizon', and 'New Enterprise'. I knew I could name a ship 'Enterprise' somehow.... :)

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.

The listed Class specs are in some cases hypothetical, but some data such as ship lengths, weapon stats and crew complements are established as official. For an explanation on what the Ship designations mean, see Spec Definitions.
