The HCS Space Navy (HCSN) have broken convention by announcing their planned programme of fleet upgrades. Usually the HCSN, like most parts of the HCS are very secretive about their plans. With fleet building slowing down the HCSN has put a lot more emphasis on improving what they have.
The building of the Cosmos class does continue apace however and the HCSN plan a fleet of well over 100. Building will shift to the new upgraded S Class early in 2106 however. This will feature a new engine that boosts speed dramatically, up to 650c though we understand cruise will be more likely 600c. The super-energy cannon has also been upgraded, now said to be the equal to the Z cannon though this has been untested in practice.
10 Molentic Tuuls will be upgraded to the new GX Class, which includes improvements to performance, firepower and equipment. Its thought all MTs will be upgraded to GX eventually. 25 Kalahati Tuul 2s will also be upgraded to the N class, this also includes better performance and firepower/equipment.
Its clear that HCS efforts to improve their lagging spaceship powerplant technology has borne fruit as speeds approaching 600c are now expected. However as the DDS and Dinos are looking at 800-900c as a baseline its clear they still have a lot of work to do.
