To meet the heavy transportation needs created by the rampant expansion of Earth’s sphere of influence, UESF needed something more substantive than the modular freighters built since the beginning of the century.

The ship that actually emerged from the project could carry a thousand passengers or 17,900 tons of cargo at warp 2, larger loads still at speeds below that, and reached the speed of warp 2.75 when empty of load.

To meet the heavy transportation needs created by the rampant expansion of Earth’s sphere of influence, UESF needed something more substantive than the modular freighters built since the beginning of the century. In May 2142, the recently instated Fleet Logistics Division ordered the development of a large warp transport capable of warp three when empty and warp two when loaded. The ship that actually emerged from the project could carry a thousand passengers or 17,900 tons of cargo at warp 2, larger loads still at speeds below that, and reached the speed of warp 2.75 when empty of load. Christened the Vanguard class, the cargo vessel had an admirable operational range of 100 ly, or about 12 years of travel time, with full fuel load and ramscoop replenishments.
This theoretical figure was never translated to practice. For the first decade of Vanguard operations, Earth’s ambitions did not extend beyond 20 ly from the home system, and UESF ran very few operations on the outer rim. In the Romulan war, the ships in turn traveled lightly loaded at warp 2.5, hopping from colony to colony. Traveling from Earth to war zone starbases at full load would have taken about six years.

Each impulse nozzle was coupled with a forward-facing ramscoop. Twin main fusion reactors, twin warp coil assemblies and spacious fuel tanks were also part of this section, which could be considered a spaceship on its own right.
Three main types of cargo could be carried. Forward of the drive section, a series of plates covered an unpressurized hold area for vacuum goods and components.
