General Information

In the late 1980s the Kutherburg Department of Defense proposed a diesel-electric submarine design to replace the Bucto class. The new submarine class was intended to provide a more cost-effective alternative for training and in coastal defense. The announcement for the new design took place in September 1979. Five designs were put forward, with the DOD selecting the 1,960-ton design. However, the need for export potential upped the displacement limit to 2,400 tons to allow for flexibility in construction if the need for alternative machinery and systems arose.

The Nacatan Shipbuilding & Engineering Ltd. Aletia diesel-electric patrol submarine design was selected. The submarines are 230 feet 7 inches (70.28 m) long overall with a beam of 25 feet (7.6 m) and a draught of 17 feet 8 inches (5.38 m).The submarines has a complement between 792 and 797 with the Royal Kuthern Navy.

The submarines have a single-skinned, teardrop-shaped hull constructed from NQ1 high tensile steel. The hull is fitted with elastomeric acoustic tiles to reduce the submarine's acoustic signature. The class has a reported dive depth of over 650 feet.
