The class' eight 26.5-inch torpedo tubes allow it to both operate the munitions previously described or be used for special operations, allowing special forces to deploy a torpedo-shaped mini-submersible for extended range operations from the vessel in question, although the class is also designed to be able to operate a mini-sub docked on the top of the boat, a specialised dry-garage to allow the operation of smaller mini-submersibles, or potentially unmanned underwater vehicles (UUV). | |||

Design
The Narwal-class design is based off of the older Brande-class SSN which it is currently slated to replace in service. The class was titled Project 15124 until the announcement of the first ship of the class, the Narwal. The design follows requests by the admiralty for a modern, top-of-the-line submarine capable of long duration expeditions from a home port along with an ability to conduct changing, complex operations ranging from anti-shipping duties, anti-submarine duties, and intelligence gathering operations. The final version now in operation is capable of conducting a wider range of operations away from Velikoslavian waters than any previous design, with some theorising the operation of complicated mini-submersibles for special operations in foreign waters.
The design of the submarine has resulted in a 118.50 meter length with a 13.7 meter beam, displacing some 8,923 metric tons while surfaced increasing to 14,523 metric tons when submerged.

The hull of the design is constructed utilising HY-100 nickel-alloy steel to allow it operate at such depths as previously described and is built in one phase around a completed pressure hull with special cutting areas for reactor replacement during refits. The submarine is covered in more than 43,500 classified anechoic tile which minimises sonar detection by both absorbing and distorting sonar waves and are attached utilising high-strength adhesive designed by the Velikoslavian government specifically for the role. The tiles, which are produced and attached in parts, have previously been prone to failures (falling off due to impacts with sea-life or underwater objects), have so far not suffered failures following the introduction of the new high-strength adhesive on the first ship of the class.
