The Zeedier-class submarine is a Knootian-designed diesel-electric (SSK) submarine. It was originally commissioned during the Vogels administration as the first real Knootian combat submarine and – for a long time – the first-of-class KDF Dolfijn was the only submarine in service for the Marine of the Knootian Defence Force! The Dolfijn herself is now on display in a museum in Den Helder, although many of her sisters still serve the Marine faithfully.
Crewed originally by 49 men and women, the Zeedier-class submarines had much better crew facilities than other classes of comparable size and design. A decent diesel-electric engine plant gave the Zeedier class a good underwater range of 800km, and made it sufficiently silent underwater for effective use in reconnaissance and escort missions. The engine arrangment gave the submarine a speed of 17 knots when surfaced and 20 knots submerged, and the submarine could reach a maximum depth that exceeded 300 metres. The boat could carry up to 30 underwater mines OR 19 21" torpedoes. With a then-new hydraulic torpedo reload system it could reload all four tubes in less than 5 minutes. The submarine was also capable of firing medium-range anti-shipping missiles, though these were rarely carried.
The Zeedier-class was extensively used to patrol the Reich coast as part of the cold war between the Reich and SATO, and underwent a Mid-life refit that brought them up to date with the modern state of submarine warfare, which included further automation, new sensors and a larger weapon load. Nowadays the class is being taken out of rotation in offensive Battlegroups but still finds a role as an escort and coastal patrol vessel until a sufficient number of nuclear submarines has been built to replace them, though this is still a considerable time away.

- Basic Composition
As with most submarines per se, the Zeedier class carries little armour. However, she is fitted with a dual pressure hull, anechoic tiles (to reduce sonar signature and noise emission), and reinforced hull bracing to protect against underwater detonations.
