In the files for Star Fox 64 found in the 2020 Nintendo Gigaleak are references and assets for what appears to be a scrapped level named "Battleship". The string fox_map.c interchangeably calls it "Battleship", "Giant Battleship", and "Ground Ship"; it's possible that the latter could be a mistranslation of "Grand Ship", as they're spelled the same way in Japanese. The stage used a full 3D model, like Area 6 and Bolse, as its icon on the map selection screen. Its intended location was where Sector Y currently sits on the Lylat map selection screen, which is the hard path taken from Corneria, and its two branching pathways were known to be Zoness on the hard route and "Fortuna" (Fichina) on the normal route. According to the string fox_play.h, it was an all-range mode stage, and the audio_game.h string makes it appear that it was going to reuse Bolse's theme for its background music, implying that there would have been multiple phases for the level. This stage also had its own enemy data file, implying that it would have featured other enemy ships of some sort.

In October 2024, a group of modders and hackers responsible for the Star Fox 64 Decompilation Project were able to recreate this discarded stage via a fanmade patch.
