An excerpt from Memory-Alpha:
The USS Rhode Island (NCC-72701) was a variant Nova-class Federation starship in service during the late 24th and early 25th century.
Even though the original Nova-class from the 2370s was limited to a maximum warp factor of warp 8 and was considered a planetary research vessel, the Rhode Island was designed for long term deep space assignments.
In an alternate timeline, the Rhode Island was commanded by Captain Harry Kim, and assigned to a four-year exploration mission. In 2404, the Rhode Island defended Admiral Janeway's shuttlecraft when it came under attack by two Klingon Negh'var warships. (VOY: "Endgame")
The Rhode Island Nova-class variant was used by the Federation in the Battle of Procyon V in the 26th century. (ENT: "Azati Prime")
