In it's early days the DDS operated a rag-tag fleet of one off spaceships as it learnt the ropes of operating a space fleet. What happened to those ships operated in the early-mid 2090s?
Starhunter UM
A medium-sized scout ship rebuilt from a commercial design. It was used for reconnaissance and light attack. It was destroyed in combat with the Clones near Sandworld.
Solaris
A prototype long-range scout ship based on a UNP Space Patrol design. Solaris was withdrawn from service in the early 2100s due to fatigue and obsolescence. The Solaris was used as the basis of the upgraded Solaris II production class which served with distinction in the early 2100s. The original Solaris is now in the Proxima Space Museum.
Dinomark ZX
The ZX was a prototype ship built by the Dinos in the 2180s, their first large warship. The ZX was withdrawn due to poor performance, the Dinos later building the much more successful Dinomark RS. The ZX was sold to the DDS to give them experience in operating a large warship. However, it's combat potential was limited due to a lack of power and it only saw limited use. It was withdrawn when the DDS has sufficient Pulsars in service. The ZX's fate is unclear, it is thought to have been scrapped.
