single reactor is for a warp mine II I believe? Only BP I havn't seen.
Propulsion connector is for warp drive III.
<edit> I read it wrong, uses basic propulsion, so not sure...
Odenfield was a hanger part I dont think there is anything that might use it, yet.
I know I have looted single reacotrs and propulsion connectors recently, but not odenfield ever.
