The navy of the Grand Yarphese Republic and of the Vietnamese Liberation Army, known as the Vietnamese Liberation Navy (abbreviated VLN), deals with all military matters on water or in space. This ranges from patrol of river borders such as the Tonle Sap River to naval battles overseas. This branch is centered at Khuâyđầy Platform, one of the most advanced military facilities of Yarphei, recently rebuilt after being demolished by a fusion bomb. The navy, the largest branch of the Vietnamese Liberation Army, has about 2400000 members.
