In the Avatar: the Last Airbender TV Show, the Fire Nation serves as the main antagonists and they have the best navy in the show. All of the ships are scaled to each other and are listed from smallest to largest. The scale 1/1000 and 1 millimeter is meter.

There are many different sizes and types of ships and these are the bigger ones. The Southern Raider's Frigate is briefly seen in Book 3 and is used to raid and pillage the Southern Water Tribe. Fire Prince Zuko's ship from Book 1 is the most recognizable ship from the show and is a old variant of the Fire Nation Cruiser. It is prominently featured as it pursues Avatar Aang, but it is destroyed by pirates. There are several different variants of the Fire Nation Cruiser depending on who drew the ship. They were frequently seen throughout the entire show and were effective fighting machines. One has a three smokestacks, one has a curve in its superstructure, and one has two large smokestacks. They are simply designed and were mass-produced by the industrial Fire Nation. Zuko's Royal Sloop appears in the graphic novel, The Promise, and is only seen once. It is smaller and faster than Azula's Royal Sloop. Her Royal Sloop is larger and more ornate than Fire Nation Cruisers and is seen in Books Two and Three. The huge Empire Class Battleship dwarfs all other ships. Admiral Zhao uses one when he assaults the Northern Water Tribe in Book One. The front of it is based loosely on a lion turtle with some dragon elements. Its only apparent weakness is sharp outfits.

Now updated with Ozai's Royal Sloop, which is briefly seen in the background in Book Three.

Now updated with Iroh's version of the Empire Class Battleship; it does not appear in the TV show. Compared to the Empire Class Battleship, it has a different superstructure and the front is based on a dragon because Iroh is known as the Dragon of the West.

Now updated with Fire Lord Zuko's smaller Royal Sloop which he uses to come back to the Fire Nation Capital in the comic arc Smoke and Shadow. Also included is the Fire Nation Transport Ship which is seen briefly in the Promise Comic Arc.

Now updated with Sozin's Royal Sloop and Azulon's Royal Sloop, neither of which appear in the TV Show. Sozin's Royal Sloop is small and austere, reflecting his attitude. Azulon's Royal Sloop is large and has a turtle-inspired front because of his royal portrait and his domination over the other nations.
