The Cosmos is a Raegris design which the Clones bought the licence rights to many years ago as a back-up for their Kalahati Tuul programme. During the Clone-Utrek War of 2101 the vast bulk of the HCS fleet was Utrek derived but these ships were rendered useless by a trojan virus planted by the Utrek. Only the small number of Cosmos and a couple of ex-Bolitic ships remained available until the virus could be defeated. After the war the Clones embarked on one of the largest ship building projects in history and set out to make the Cosmos the basis of their fleet (at the time they had just 6). At one stage a new Cosmos was entering service every 2 days as the Clones poured in vast resources to build a huge fleet of these ships to form the new basis of their fleet.
The Clones also improved the breed with weapons, system and engine improvements. The current Cosmos S is one of the best warships around, so good that the Raegris are to upgrade their own Cosmos along the lines of what the Clones have done.
But now production has ceased, a few ships early as the Clones want to start rebuilding their oldest Cosmoses which have reached the end of their fatigue lives. It is likely the Clones will maintain a fleet of 100 of these reliable, popular and versatile ships into the 2120s.
Unfortunately for the HCS recent budget restrictions mean the rebuilt Cosmoses will not be as potent as originally intended. The Cosmos SR was basically going to be older Cosmoses rebuilt to S standard. Now the rebuilds will be of the Cosmos K type which will retain much of the original systems and engine.
