Shen's Fleet was an armada of sea-faring ships that were owned by Lord Shen, which he used to transport his army (mainly his wolf warriors) and cannons to Gongmen City's harbor to begin his conquest for China.
Having been based off of commercial Chinese junk boats, it is presumed the majority of these ships were constructed before or around the time of the Peacocks' rule over Gongmen City. At that time, however, they were most likely being used to transport goods and other commercial items for the city by use of the landscape's rivers. It is also presumed these boats remained in the city's harbor even after Shen's exile and the Kung Fu Council's stewardship over the city.
The fleet also took the place at the Battle between Kung Fu Masters and Shen's Army, when the warriors used the front boats the block the harbor entrance and trap the entire fleet within the canal. However, an enraged Shen fired his cannon from his flagship, obliterating a number of boats and injuring the masters. The dozen or so ships that remained sailed into the harbor and confronted the Dragon Warrior for the last time.
Po destroyed the fleet when Shen's wolves were trying to kill Po with the cannons, but kept throwing the ships' cannonfire back, turning the cannonballs against Shen's own ship. Shen's flagship was the last to be hit by cannonfire, and its remains were the location of Po and Shen's final confrontation.
