The Leander-class, or Type 12I frigate, was among the most numerous and long-lived classes of frigate in the Royal Navy's modern history. The class was built in three batches between 1959 and 1973. It had an unusually high public profile, due to the popular Warship BBC television drama series.
The Leander design or derivatives of it were also built for other navies. In addition to the Royal Navy and its branch the Royal Indian Navy, the Royal New Zealand Navy, Chilean Navy and Ecuadorian Navy operated Leander-class ships, while the Royal Netherlands Navy and Indonesian Navy's Van Speijk-class and the Royal Australian Navy's River-class were based on the Leander-class design.
