The Crankcase project to develop a new patrol ship in the late 2120s has been cancelled though the project had been on the back burner for some time. A new project that has been announced by DDS Research is Clearwater (following the C-designations used recently for new ship projects).
Clearwater is the project name for the proposed Medium Unmanned Reconnaissance Vehicle (MURV) which is the DDS counterpart to the HCS Nybble NL. Clearwater will also be armed and have a strike role. It is thought Clearwater will be similiar in size to the Pentekonter and thus in some ways is a replacement for the Crankcase project. The DDS have begun initial design work and aim to have Clearwater in service by 2116 or 2117.
Its not clear yet how Clearwater will integrate with the FLUSV unmanned strike vehicle project which is part of the future cruiser Chrysalis project though one DDS Research insider said FLUSV would likely be a variant of Clearwater.
