The Tian Xia navy is the naval branch of the Tian Xia Department of Peace. It is one of the larger navies in the world, though lagging well behind Wilkonia and Tonkin. It was reformed after the Jieshi reorganization that stripped the majority of the nobility of their military roles. It does not trace direct lineage to the navy that existed before the listed date, resulting in the 1818 creation date. However, Tian Xia had a naval force well back in the 10th century.
