The 4th Fleet was a naval unit that is part of the Usean Allied Forces. Their leader is Captain Liam, who was aboard the flagship, White Valley.


On August 13, 1998, the 4th Fleet needed to pass through the Payton Channel. This was a path to the rebel base that needed to be destroyed. However, the channel was heavily fortified and they were escorted by the Scarface Squadron during the mission. With their help, the advance was a success and the rebel base was destroyed.[1]
