"Armada" refers to a large fleet of ships, typically used for military purposes. Historically, it is often associated with naval warfare, where multiple vessels are organized to engage in battle or protect a territory. One of the most famous examples is the Spanish Armada, which attempted to invade England in 1588 but was defeated. In modern contexts, "Armada" can also refer to various media, including books and video games. For instance, the novel Armada by Ernest Cline features a young gamer who finds himself in a real-life battle against alien forces, blending elements of science fiction and adventure.
