Kiracu-class TL11 Large Planetary Defence Missile Submarine

This article originally appeared in the March 2013 issue of Freelance Traveller.

The Kiracu is the official planetary defense design from Enrii Maritime Industries LIC of Keplo/Core. The design has been licensed to Instellarms, who manufactures and sells the submarine through the rest of the Imperium.

The Kiracu is primarily a covert missile launching platform used to engage starships in orbit or within the atmosphere whilst remaining undetected. It is designed to survive initial orbital bombardment by remaining undetected and provides its owners with a retaliatory strike capability.

Its main armament is a single 100tn missile bay arranged as a vertical launch system supported by an extensive magazine. Missiles can be launched from 100m below the surface and guided to their targets using extensive passive sensor arrays. The use of passive sensors, EM masking and the cloaking effects of the water ensure that the submarine remains undetected between launches.

A limited self-defense armament is retained, including two remote beam laser turrets for close-in laser defense against torpedoes, a small anti-submarine missile system, and long range anti-aircraft missiles. These are primarily designed to protect the submarine against grav vehicles and small attack submarines engaged in anti-submarine work. The hull has been strengthened to increase the maximum dive depth to allow the submarine to flee attack submarines and orbital return fire.

Given the long duration of patrol cruises, each crew member is assigned a small stateroom, and sufficient fuel and supplies are carried for up to 90 days cruising.
