USS Theodore Roosevelt

The USS George Washington (CVN-69) was a United States of America / aircraft carrier in US Navy service on Earth in the 20th and 21st centuries, named for President of the United States of America Theodore Roosevelt. This vessel may have been succeeded in name by such vessels as the 23rd century Federation starships USS Roosevelt. 

Background
The identification of the Theodore Roosevelt as  is based on a reference to its  sister ship, USS George Washington (CVN-73). In the novel Ghost Ship, the ship is referenced as belonging to the Enterprise-class, despite the fact that the real-life vessel, like the Theodore Roosevelt, was as part of the Nimitz-class. The George Washington was not yet in service at the time of the book's writing in 1987. The "Enterprise-class" is an uncertain designation, seeing as the prototype USS Enterprise (CVN-65) led the way for a generation of nuclear powered aircraft carriers, of which the Washington is a part, even though, in the strictest definition, Enterprise is in a class by herself since no other vessels were constructed to her exact specifications.
