Since the summer of 1994 the Tonijn
(= tuna fish) submarine has formed part of the Dutch Den Helder Navy museum
collection. The Tonijn is a three-cylinder submarine of the Dolfijn
(=Dolphin) class. This type of submarine formed the heart of the Netherlands
submarine fleet between 1960 and 1991. It was the Dutchman Ir. M.F. Gunning
who developed the principle of the three-cylinder submarine. Its construction
made for strongly improved stability and enabled the boat to dive deeper than
other submarines of its time. Between 1966 and 1991 the Tonijn took
part in a large number of squadron voyages and carried out several operational
missions. The boat has an overall length of 79.5 meters and a weight of one
million kilograms. It is the only Dutch submarine on permanent display to the
public.
The Tonijn is open to inspection from the operations
room to the galley and from the toilet to the commander's cabin. The first
thing to notice is how small and cramped the interior is. It is difficult to
imagine that a crew of 72 personnel had to work, eat and sleep in these
cramped quarters, sometimes for weeks on end. Any questions can be answered by
attendants who in most cases have sailed on submarines themselves for years. (Text:
