Waterbending-powered submarine

Waterbending-powered submarines were used to transport soldiers and equipment during the invasion of the Fire Nation.

The waterbending-powered submarines are naval vehicles designed by Sokka of the Southern Water Tribe and built by the mechanist.[2] These vessels were used during the invasion of the Fire Nation to transport Earth Kingdom and Water Tribe soldiers and benders as well as vehicles and equipment into the harbor of the Fire Nation Capital.[1]

History

After Ba Sing Se fell to the Fire Nation,[3] Sokka continued to make plans for an invasion of the Fire Nation on the long-awaited Day of Black Sun, albeit on a smaller scale than initially intended. Vehicles were needed to transport the invaders into the Fire Nation, so he personally designed submarines and presented his plans to the mechanist. Despite facing initial difficulty in interpreting Sokka's plans, the mechanist figured them out and manufactured the submarines for usage by the invasion force.[1]

Waterbending-powered submarine side-view

By traveling below the water surface in the submarines, the invasion force was able to avoid Fire Nation traps en route to the capital city.

On the Day of Black Sun, five waterbending-powered submarines were deployed by Water Tribe boats right before the boats were seized by firebenders. The submarines navigated past the Great Gates of Azulon and proceeded toward the Fire Nation Capital. Since the submarines only had a limited supply of air, they had to resurface once before reaching the Fire Nation harbor. Before reaching the shore, the submarines were easy targets for the Fire Nation defenses and multiple battlements shot harpoons at the vehicles with their ballistae. One of the submarines was hit by the projectile and, although a waterbender from the Foggy Swamp Tribe was able to freeze the hole in the vehicle, limiting the damage, the submarine was pulled out of the water. However, before it was left to the mercy of the defenders, Katara used waterbending to cut the metal chain reeling in the vehicle, causing it to drop back into the water and continue its journey to the shore.

In order to gain access to the dock, ice torpedoes were launched from the submarines to blast through the metal bars that were to prevent an underwater attack. Once they arrived on shore, the submarines released the earthbending-powered tanks, the invasion force, and the Earth Kingdom supply trucks, who stormed the Royal Plaza while the submarines were defended by Tho, Due, and Huu.[1]

After the eclipse ended, the Fire Nation drove back the invaders with their air force and quickly advanced toward the shore to destroy the submarines, thereby trapping the invaders. Huu, Tho, and Due did their best to destroy the bombs dropped by the Fire Nation airships, but they were overwhelmed, and all of the submarines were destroyed. Aang and the younger combatants managed to escape on Appa, while the elders were captured.[4]

Design

Schematics of submarine

The submarine's schematics were based on a framework developed by Sokka and finalized by the mechanist.

The vessels are propelled by waterbending, and appear to be fairly large crafts. They can each hold dozens of warriors and at least one earthbending-powered tank and two Earth Kingdom supply trucks. The vessels are armed with ice torpedoes. Each submarine has multiple windows, a periscope at the top of the roof, and three fins, one at the back of the submarine and one fin on each side, that help the submarine to maneuver.

The plated vessels are fairly well-armored overall, as they were able to withstand heavy fire from guard towers,[1] and there are armored plates at the front that can move aside to allow troops and tanks to enter and exit while the sub is on dry land. There are also doors on top of the vessel, allowing troops to walk atop the ship when it is moving through the water.[2]

Weaknesses

The only major flaw in the submarines is their inability to store oxygen. Each vessel can only stay underwater for an hour or so at any given time before it must resurface to prevent the passengers from suffocating. This is sufficient when planned for, but limits their underwater range.[1]

Trivia

  • After the Hundred Year War, the Fire Nation engineered submarines based on Sokka's schematics to include in their military arsenal. Zuko and his family used one as a means of entering the Fire Nation capital undetected.[5]
