Alameda Naval Base

The Alameda Naval Base was a former naval base for the United States Navy on Earth. The base was located on San Francisco Bay, across from the city of San Francisco.

In 1986, Commanders Nyota Uhura and Pavel Chekov visited the base after traveling back in time from the 23rd century. The pair hoped to locate a suitable nuclear reactor from which to harvest anti-protons to recrystallize the dilithium crystals of the HMS Bounty. They found the USS Enterprise (CVN-65) docked at the base, and returned later to harvest the anti-protons. While Uhura was able to escape, Chekov was detained by the crew of the Enterprise, and was seriously injured attempting to escape. (Star Trek IV: The Voyage Home).

The U.S. Navy closed the base in the late 1990s.
