USS Nelson (NCC-1843)

The USS Nelson (NCC-1843) was a Federation starship in service in the late 23rd century.

The Nelson, described as a "close-cordon patrol cruiser", was encountered by a covert, cloaked Starfleet Intelligence scout ship attempting to cross the border into Rihannsu space on a field agent insertion mission. The Nelson was observed to defend the Federation border vigorously.
