Class-5 probe

A class-5 probe or more specifically class V mid-range reconnaissance probe was a type of probe used by the Federation Starfleet in the 24th century.

The probes had a range of 4.3x1010 kilometers. They were powered by a dual-mode matter/antimatter engine which could propel them at warp 2. Their sensors included extended passive data gathering and recording equipment and fully automated systems for mission execution and return. 

In addition to that, these probes had a hull made from stealth material and could be used for tactical purposes with the addition of a sensor jammer packet.
