The P-1113 Kottos were two Kottos-class aerial warships developed by the Eastern Faction built during and completed after the Estovakian Civil War to support the P-1112 Aigaion. Their primary function was to provide Electronic Support Measures to the Aerial Fleet. Like the Aigaion, they fall under the jurisdiction of the Estovakian Navy and were built using technology provided by Belkan War veteran Lorenz Riedel.
Both Kottos units first joined the formation with the P-1112 Aigaion during the Emmeria-Estovakia War around the time of the Invasion of Gracemeria. Throughout the war, both Kottos units continued to support the Aigaion until the Aerial Fleet was ambushed by the Republic of Emmeria Air Force and both units sunk into the Fuscum Sea, nearby the Glava Islands.
