The cruisers of Anastasios Tsamados Class were the first such warships designed on Hellenic Kingdom post WW2, built from 1960 to 1969. Two variants built in a common hull, somewhat similar with the USS Truxtun, but with convectional steam turbine propulsion instead of nuclear plant. Tsamados Class had Mk10 GMLS Mod 7 with Terrier and ASROC missiles and Kapodistrias Class had larger aviation facilities at rear and a Mk13 GMLS front. Initially planning was for three hulls from each variant, but in the end only 4 built (2 from each variant) and in their place three additional Kimon Class DDGs were built. Although these cruisers did not upgraded to NTU as Kimon and Nikiforos Fokas Classes, they received a refit to their armament. First upgrade was Harpoon missiles (from 1978), then in early 1980's the obsolete MK25 GMLS replaced with Mk29 and also sensors were replaced with newer.
Propulsion was twin hellenic origin steam turbines with reduction gear from METKA (ΜΕΤαλλικές ΚΑτασκευές, = Metal Constructions), a company with roots back in late 19th century. METKA main products are power plants for coal/lignite/oil/natural gas fired power stations, nuclear power stations and hydroelectric turbines, plus hulls for tanks and other armored vehicles built in Hellenic Kingdom. Each cruiser had four 650 psi "Ioannou - Mitilinaios" boilers, originally designed in 1930's with 400 psi steam pressure. The post WW2 improved version came in several horsepower variants and installed in ocean liners as well. Although obsolete and not very fuel efficient, the METKA plant was incredibly reliable.
Armament was a mix of old and new weapons of 1960's, eg the main gun was the fictional Pyrkal 120/45 Y1938/52/65 HE gun. This was based on British 1930's designs but with a different turret, loading mechanism and tray, capable of much higher elevation, up to 75 degrees, being a dual purpose gun with anti-aircraft and anti surface capabilities. It entered service in 1938 ("Y" in Greek is "Υπόδειγμα", in English translates in "Model") , diameter was actually 4.7", but Hellenic Kingdom used the metric system and the gun was designated 120mm with a 45 caliber long barrel, identical with its British ancestors. Next numbers indicate improvements, in 1952 and 1965.
