In Lost, what is the name of the abandoned DHARMA Initiative submarine?

In Lost, the abandoned DHARMA Initiative submarine is named the Galaga. The vessel is found on the island and becomes part of the survivors’ escape plans.

The Galaga is connected with the DHARMA Initiative’s operations and is distinct from the Elizabeth, Desmond Hume’s sailboat. The submarine provides a practical route on and off the island, making it strategically important to Benjamin Linus and later to the survivors.

The name is easy to mix up with the Black Rock, an old sailing ship that reaches the island in the nineteenth century, or the Elizabeth, which Desmond uses in his pre-island story. The submarine’s name is a specific detail from the show’s wider collection of vehicles and vessels.
