Following the technology tie up with both the Dinos and Sirikwanese the HCSN have formed a company called HCS Submarine Technology which will be producing submarines for the service at a new facility being built on Cloneworld but with factories on Dino-Land and Sirikwan also to produce major components.
The first boats produced will be 4 Seawolf class SSKs for local patrols, these will be developed versions of the singleton Tinfisk SSK which is the HCSN's only current submarine. The main focus of development will be nuclear powered boats, the Sealion SSN and Walrus SSBN classes which will share as much hull and equipment as possible. Sealion SSNs will be able to fire torpedos and cruise missiles while the Walrus will be equipped with 12 SLBMs known as SeaGale, based on the Gale-III ICBM currently in development to replace the Gale-II IRBMs around the Central District.
The timescale for the submarines has been listed at 2110-2112 for Seawolf, 2114-2117 for Sealion and 2116-2120 for Walrus though analysts think this may be slightly ambitious.
The HCSN have also announced they have contracted Clone Air Corporation (CAC) - the largest Clone aircraft manufacturer - to design and produce an amphibious seaplane for patrol and air/sea rescue.
