The Academy’s presence is closely tied to the History and Tradition of the Hellenic Navy. The first effort to establish a Naval Boys’ School was made by the Decree of 17 March 1879, which provided that “…the crew of the steam vessel ATHINA, to be fitted out after the completion of its repairs, shall serve as a school for non-commissioned officers, seamen and boys…”.
Since then, the Academy has existed and operated to this day under various names. In 1887 it appears for the first time under the name “Central Training Depot” (Κεντρικό Προγυμναστήριο) on Poros. A year later, in 1888, the “Naval Boys’ School” was established aboard the ironclad Vasilissa Olga. From 1909 to 1924, the Naval Boys’ School was relocated to the facilities of the “Central Training Depot” on Poros, where in 1924 it was renamed the “Cadet NCO School” (Σ.Δ.Υ.). In 1920, the “Technicians’ School” was founded at the Salamis Naval Base. In 1936, the “Cadet NCO School” (Σ.Δ.Υ.) was abolished and the “Naval Boys’ School” resumed operation.
From 1941 to 1945 it did not operate because of the war. In April 1945, it resumed operation as the “Royal Training Depot of Poros” (ΒΠ ΠΟΡΟΣ). In 1948, ΒΠ ΠΟΡΟΣ was renamed the “Poros Training Centre” (ΚΕ ΠΟΡΟΣ), and in 1969 the “Naval Cadet NCO School” (Σ.Δ.Υ.Ν.), based on Poros. The Technicians’ School (at the Naval Base) was renamed in 1970 the “Naval Cadet Technician NCO School” (ΣΔΥΤΕΝ), in 1980 the “Technicians’ Training Centre” (ΚΕΤΕΧ), and in 1984 the “Sakipi Training Centre” (ΚΕΣΑΚ). On 18 December 1981, ΣΔΥΝ was renamed the “Hellenic Navy NCO Academy”, based on Poros, from where on 13 August 1991 its seat was transferred to the Palaska Training Centre (ΚΕ ΠΑΛ) in the SKARAMANGAS area, where it operates to this day. Since 5 July 2000, when ΚΕΣΑΚ was abolished, the Academy has remained the single, unified production school of career Navy NCOs for all of their specialties.
