Underwater Reactor is a field map in Final Fantasy VII located in the Junon Area and reached in an elevator via Junon. The dungeon is visited for "Clash in the Deep Sea", when a party led by Cloud travel there for Huge Materia. Here, the party obtains a submarine. As well as this quest, the area is notable for the Ghost Ship, from which Guide Book can be morphed.

Quests[]

Junon Underwater Reactor is the first location visited when Cloud returns as party leader. The party must reach the reactor to search for the Huge Materia, and obtains a submarine at the end of the quest.

A dog blocks a doorway to the red submarine's dock and will only move if the player loses the submarine minigame (their sub will sink). In this case the party can return to the Junon Underwater Reactor and find the dog has moved. The door the dog was guarding leads to another submarine dock from where the player can get a red submarine.
