The Zwaardvis class ("Swordfish") submarines were designed by the Royal Netherlands Navy. In comparison to the three-cylinder design of the Dolfijn-class submarines, the Zwaardvis class submarines are based on one cylinder. The reasons why the Royal Netherlands Navy and its partners choose for this design was because it resulted in more space within the submarines, which would give the crew a more spacious accommodation and make it also easier to set up machines within the submarines. The hydraulic system of the boats included three pumps and three accumulators. They were equipped with controls sliders made by Rexroth.

In addition, the submarines are based on the U.S. Navy Barbel class with the teardrop hull design, which results in the submarines producing less noise. The propulsion of the Zwaardvis class is also different from the Dolfijn class submarines, for example, it has a single propeller instead of the two propellers the latter has. Furthermore, it has more diesel engines, the batteries require less charging time, it can launch missiles and torpedoes from greater depths, the diving depth has increased substantially, and lastly it can stay longer submerged. The introduction of the Zwaardvis class submarines also led to the Royal Netherlands Navy using the Mk.37 torpedoes. In 1988 the Mark 37 torpedoes for the Zwaardvis class submarines were replaced with the newer Mk.48 torpedoes.
