Vissian starship
Vissian starships were advanced craft employed by the Vissians during the mid-22nd century.

The engine core of this class was constructed of over 200 elements, and had no need for magnetic confinement due to special fuel injection processes. It also emitted omicron radiation during its operation. Humans required inoculations to get in close proximity to an active engine core.

Much larger than than an Earth  starship, the Vissian ship could support family-style quarters with dining rooms, a mess hall, an astrometrics lab, and carried at least one stratopod for scientific operations. Its hull was constructed of trinesium which could withstand temperatures up to 18,000 s.

This class was first encountered by Earth Starfleet in 2153 by the starship . ()
