These guns have an unusual history. They were originally developed for the Almirante Latorre class battleships built for Chile. But when Chile was unable to take delivery, they were brought into Uk service as Mk-XXI six-inch guns. Five were purchased for NZ initially, with a sixth purchased in 1942 for Palmer Head. The guns remained in service till 1957, but remained onsite till 1960 when they were scrapped. No examples remain in New Zealand.
