The submarines Hr.Ms. Zwaardvis (S806) and Hr.Ms. Tijgerhaai (S807) were conventional (diesel-electric) submarines of the Zwaardvis class, built for the Royal Netherlands Navy in the 1960s and 1970s. They were modern and quiet, designed for Cold War operations, with an emphasis on NATO cooperation and anti-submarine warfare (ASW).

Both submarines were mainly deployed for NATO missions in the North Atlantic, the North Sea and the Norwegian Sea.
Tasks:
Anti-submarine warfare (ASW)
Intelligence gathering
Exercises with NATO units
Simulation of enemy submarines in NATO training exercises
Both ships were known for their low noise profile, making them difficult to detect.
Both submarines were decommissioned in the 1990s due to obsolescence and high maintenance costs.
Attempts to sell them to countries such as Malaysia and Indonesia failed.
They were eventually scrapped in the Netherlands.
The Zwaardvis class was based on the design of the American Barbel class, with Dutch modifications.
They formed the transition to the later Walrus-class submarines (1990s), which are still in service.
The vessels were ahead of their time in terms of silent propulsion and hydrodynamic design.
