Class-1 probe

A class-1 probe or more specifically class I sensor probe was a type of probe used by the Federation Starfleet in the 24th century.

The probes had a range of 2x105 kilometers. They were powered by a vectored deuterium micro fusion engine which could propel them at warp 0.5. Their sensors included full EM-subspace and interstellar chemical palette for use in space.
