Class-2 probe

A class-2 probe or more specifically class II sensor probe was a type of probe used by the Federation Starfleet in the 24th century.

The probes were essentially modified class-1 probes and had a range of 4x105 kilometers. They were powered by a vectored deuterium micro fusion engine which could propel them at warp 0.65. In addition to the equipment found on the class-1s, these probes had enhanced long-range particle- and field-detectors and imaging systems.
