The Kortenaer class was a class of anti-submarine frigates of the Royal Netherlands Navy. As some of the other frigates of the 1970s and 1980s, they featured a COGOG (combined gas or gas) propulsion system with separate cruise and sprint gas turbines. Ten were built by de Schelde in Vlissingen and two by Wilton-Fijenoord in Schiedam between 1978 and 1982. Only 10 served with the Royal Netherlands Navy: two were sold to Greece while still under construction and replaced by two Jacob van Heemskerck-class frigates which are basically an anti-air warfare (AAW) variant of the Kortenaer class. The Greek frigates were renamed the Elli class.

Eight similar ships were built by Germany during the same period as the Bremen class.
Authorised in the late 1960s, the 'Kortenaer' class was designed to replace older ASW vessels in service in the Dutch navy. Propulsion and machinery were based on gas turbines, giving the maneuverability and speed needed when hunting fast nuclear-powered Soviet submarines.
These frigates did not receive substantial upgrades during its career.
Two ships, Elli and Limnos, were built for the Greek Navy in 1981, they are referred to as the Elli-class frigates by the Hellenic Navy and have different equipment and weapons from the Dutch ships.
The Imperial Iranian Navy ordered eight modified ships from Royal Schelde but the contract was canceled after the Iranian Revolution.
