The Zwaardvisch class was a class of initially two, and later four, submarines that served between 1943 and 1965 in the Royal Netherlands Navy (RNLN). They were former T-class submarines. Two were acquired and transferred to the RNLN during the Second World War, while another two were loaned from the Royal Navy post-war for a period of five years.
