The HCSN have been demonstrating their newly updated cruise missile the SS-NS-3 which is equipping the submarine fleet. The latest model the SS-NS-3A has a 3200km range and improved guidance and control systems. It can also be fitted with a nuclear warhead which means it could be used to strike back against a Cloneworld invasion force (which is a core part of the HCSN's role). Although it could not reach an enemy deep on the main continent it could prove a very useful weapon striking against an enemy closer to coastal areas.
The 3A will be rolled out across the fleet over the next few months, older missiles will be upgraded. This will be the principle weapon of the HCSN submarine fleet until the introduction into service of the SeaGale SLBM.
