Although these ships are AU,are very close to real ones owned by Hellenic Navy.Designed and built by Anastasiades-Tsortanides Shipyard in late 1970's,the first 2 are Lighthouse Tenders (in HLK the Navy is responsible for lighthouses,as in real Greece) and the sole Nautilos is a Maritime Research Vessel owned by the Hydrographic Service of RHN.
