Initially, the Confederate navy was not going to build destroyers armed with missiles. Anti-aircraft missiles were regarded as belonging cruisers.
However, the emergence of a long-range bombers Tu-16 with AS-5 "Kelt" missiles in the hands of Colombian and Venezuelan socialists in the early 1960s, forced the Confederacy Navy to reconsider the position. The anti-aircraft missiles armed ships were needed to cover the "counter-submarines operational squadrons" consisting of destroyers.
The Parliament of the Confederation flatly refused to allocate money for building a new missile cruisers. However, the naval program in 1964 budget included the 4 new destroyers and admirals have decided to take advantage of it.
"Confederacy"-class destroyers were the first missiles-armed ships built in South America (weapons and radio-electronic equipment components were British-made). They had a displacement of about 4000 tons.
Their main armament was twin anti-aircraft missile launcher "Sea Bloodhound", British production. Reloading was a horizontal: 16 spare missiles were stored in the hangar.
Artillery guns were two twin 4.5 "/ 45 (11.4 cm) QF Mark V installation.
In the bow was mounted the "Ikara" anti-submarine rocket launcher.
