The USS Saratoga (NCC-1887) was a Federation Miranda-class starship active in Starfleet service in the late 23rd century. In 2286, the Saratoga was patrolling Sector 5, near the Klingon Neutral Zone, when it began tracking a large unknown alien probe on an apparent trajectory to the Terran solar system. Attempts to communicate with the probe were negative on all known frequencies. Saratoga would eventually be neutralized by the probe's signal, and rendered unable to generate its own power, forcing it to run on reserve power only.
