Starfleet operated many starbases and outposts to support its operations throughout the Alpha and Beta Quadrants. It also fielded thousands of starships that operated in a range of missions, from sector and planetary defence, exploration, scientific study, logistically support, to diplomatic missions. While Starfleet operated specialised vessels it highly valued a multi-mission approach to starship design that saw many of its vessels apt at performing combat operations as well as scientific missions.
Officer candidates for Starfleet had to complete training through the Starfleet Academy, which had its headquarters in San Francisco. Enlisted members also have to undertake training, though not necessarily at the Academy.
Starfleet organised its starships into numbered fleets that contained several hundred vessels. These fleets were made up of several tactical wings, which could be broken down into wings and squadrons. The fleet also used task forces, though these tended not to be permanent ship groupings.
