How many Leander-class cruisers were built?
Short answerEight ships are commonly grouped together: five British Leanders and three modified Amphion-class ships later transferred to the Royal Australian Navy.
NotesLeander, Orion, Neptune, Ajax, and Achilles were the five ships built to the original Royal Navy design. Amphion, Apollo, and Phaeton formed a modified subclass rather than three more identical Leanders. Those ships entered Royal Australian Navy service as Perth, Hobart, and Sydney. The headline total of eight can therefore conceal an important design and service distinction. The count also places the South Atlantic cruisers in the broader interwar construction story.
