The Klingon-Rhiannsu technology exchange was not limited to ships IMHO...
This is Darkdrone's OLD converted KA Klingon Outpost. The model is over four years old and the textures are awful to work with. This is the best I can do given how the textures were mapped. I know use this as my TMP era RXCPL/RBS and the X-3 Aviary as my RSB.
Next up, a Merchantman pusher TUG by Atrahasis.
I figure that both the Merchantman and the TUG/pod could be captured prizes refurbrished for the ISC during the War of Pacification. In my corner of the Trek universe, the ISC would capture and use what it could given how far away they were from home...
