The USS Non Sequitur (NCC-12999) was a 24th century Federation starship operated by Starfleet. In 2364, Captain Sandy Fries was the commander of this ship. In that year, this ship patrolled the Romulan Neutral Zone. While on patrol, on stardate 41541, the ship received an order about revisions to the patrol schedule from Admiral Gregory Quinn of Starfleet Operational Support Services. According to that order, the Non Sequitur was to modify its defensive coverage of the zone by increasing sensor drone surveillance in the sectors 045 to 052 while decreasing it in sectors 004 to 010. In these latter sectors, active patrol duty required approval by the admiral's office.
