There's a doff assignment... Experimental Warp Core Upgrade or somesuch. Check the Engineer in your Department Heads tab in every sector (department head assignments are like personal assignments, they'll be different for everyone, but they will also vary by sector).
Note that you'll need two Matter/Antimatter Specialist doffs to even begin the assignment.
There's the Bio-neural warhead, which is a KDF torp that the Feds can get in a box, and it's main claim to fame is that it can defend itself and so some pretty jinky tracking.
The Bio-Molecular Torpedo (no wiki page yet) is the one the Roms get from a mission and hasn't been made available to the other sides yet. The main value of this one is that it's a crew killer like nobody's business.
