>>Serpent-class submarine


The Serpent class is the latest and only class of nuclear powered submarines operated by the Royal Serpens Land Navy. The first submarine of the class, HSLMS Adder was commissioned in 2011, and the last of the class, HSLMS Viper was commissioned in 2018. The Serpent class is the first class of submarines operated by the Royal Serpens Land Navy, and the only nuclear powered vessels in the RSLN fleet.


>>Characteristics


The Serpent class has stowage for 40 weapons and generally carries a mix of Tomahawk Block IV cruise missiles and Spearfish heavyweight torpedoes. The hull of the Serpent class is covered in anechoic tiles which are designed to absorb sound rather than reflect it, making them harder to locate using sonar. The class is fitted with a pump-jet propulsion system rather than a conventional propeller. The Serpent class are 85 m long, have a beam of 9.9 m and drought 9.4 m. Each vessel of the class has a complement of 140. The Serpent class has retractable fins and hydroplanes allowing the class to surface through thick ice.

The Serpent class are each fitted with a Serpens Land Electric Company PHWR5 nuclear reactor. The PHWR5 nuclear reactor is a pressurized heavy-water reactor (abbreviated PWHR). A PWHR is a nuclear reactor that uses heavy water (deuterium oxide D2O) as it's coolant and neutron moderator. Heavy water is less absorbent than regular water, increasing the neutron economy of the reactor. This allows the use of unrefined uranium 238 as the reactor fuel.

The Serpent class are fitted with the British made Sonar 2076 system, which it's manufacturer describes as having a "reputation as the world’s most advanced, fully integrated, passive/active search and attack sonar suite".
