UNDF has begun design studies on a replacement for the Solaris 37C cruiser which could enter service in the late 2130s. Although construction of the type only ended in 2117, the oldest ships (then known as the Velocity) were built in the early 2100s and will be reaching the end of their fatigue life by 2140.
DF are expected to look into a flexible design which can also be used to replace the Type 35 family which will also begin withdrawals in the 2140s.
