USS Yorktown (NCC-1717)

The USS Yorktown (NCC-1717) was a Constitution-class starship in Starfleet service in the second half of the 23rd century.

After rendezvousing with the USS Enterprise in 2268, the Yorktown was bound for the Theta VII colony to deliver vaccines. 

The Yorktown, under the command of Captain Joel Randolph, was disabled by the Whale probe near Earth in 2286. During his distress call, Randolph noted the Yorktown was without power, and their chief engineer constructed a makeshift solar sail in the hope that, once deployed, it could generate power to keep the crew alive. 

In 2293, Tuvok's father served aboard the Yorktown as a Starfleet officer.
