It is a statue of an Indonesian Navy officer wearing a Ceremonial Service Dress, complete with his sword of honor. The officer is depicted staring into the ocean, looking as if he is challenging the tides. It is meant to represent the preparedness of the Indonesian Navy for any scenario. The statue stands at a height of 60.6 meters (199ft), about the same as the adjacent building.^[1] The Jalesveva Jayamahe Monument represents the nation's future generation's optimism toward the accomplishment of the Indonesian dream.^[2]

The monument's name is taken from the Indonesian Navy's motto in Sanskrit Jalesveva Jayamahe which means Our Glory is at the Seas, It is also related to Indonesian Navy's Motto Jalesveva Jayamahe – "On The waters, We are victorious" (Jalesu eva – in the waters Jayamahe – we win).^[3]
