It's a Science Vessel that turns like a Cruiser. It's a good tanking Science Vessel as it has a nice combination of Sci and Eng BOFF Slots. It's a little weak in firepower due to have a 3/3 weapon's load and only a Lt Tac BOFF, and it's slow turn rate makes it more of a beam vessel. It's probably the most support-orientated ship in the game, though.
My sci captain loves her flying pancake of death. Grav well + Eject Warp Plasma from the Lt Cmdr Engi slot makes it a great CC boat for elite STFs, and the LT universal slot makes it very versatile all around. The other two c-store sci ships are probably better from a purely sci POV, If you're looking for a "jack of all trades" science ship, this is the one.
As far as the tachyon console... it's exclusively a PVP toy that I just keep in the bank. Drops cloak of vessels within the net.
