The Spinnaker Navy was a navy operating on the water, tasked with defending the coastal city of Spinnaker, which was located on the planet of Naboo. This aquatic force formed a component of the Naboo Royal Navy, itself a branch of the Royal Naboo Security Forces, which served the Royal House of Naboo. The naval assets of the Spinnaker Navy consisted of five Light Scouts, four Destroyers, and a pair of Naboo Cruisers. During the Trade Federation's invasion of Naboo in 32 BBY, Spinnaker experienced an attack. As the Trade Federation Droid Army advanced through the city, Droid Starfighters obliterated the Spinnaker Navy's ships from a safe distance, beyond the reach of the city's anti-air defenses.
The initial mention of the Spinnaker Navy occurred in Star Wars: Galactic Battlegrounds: Prima's Official Strategy Guide, authored by Steven L. Kent and released on November 7, 2001. Subsequently, it was featured in the LucasArts video game Star Wars: Galactic Battlegrounds, which launched later that year on November 11. The Navy is present in the Trade Federation campaign's second level, entitled "Spinnaker's Spoils," although its identification is exclusive to the strategy guide.
Within the game, the Navy's vessels are integrated as part of the Naboo Royal Navy's forces. While destroying the Navy isn't a mandatory objective for level completion, the strategy guide suggests doing so. Furthermore, the strategy guide indicates that the Navy possesses anti-air destroyers that players should target with their Multi-Troop Transports; however, these anti-air destroyers were absent from the Navy's representation in Galactic Battlegrounds.
