underwater base
Ocean floor outpost
An underwater base is a structure built beneath the surface of a body of water, designed for human habitation or operations.
In reality, these are rare research stations or military installations.
In fiction—especially science fiction, video games, and spy thrillers—underwater bases serve as secret lairs, research facilities, or refuges: The villain's underwater base was hidden in the Mariana Trench.
The term evokes Cold War intrigue and futuristic technology.
