Celestra is a deep space exploration vessel filled with scientific laboratories, research equipment and advanced sensor systems. It also features a long-range FTL drive for distant travel and designed to function for years without resupply of fuel reserves and life support.

Celestra appeared several times in fleet shots throughout the series but was not given a central storyline.

The Celestra seems to be a carry-over design similar in appearance to the "Electronics Ship" seen in the original series
