Here is the titan (exact role-name to be determined at a later date)
its got a slimmer profile than the onslaught, better armor density (if only by a bit) (and even though its hull is still smaller overall), and more gun coverage - including a rear-mounted heavy turret (only 2 light and 1 heavy missile however - all hardpoints, vs. the 4 medium missile turrets of the Onslaught.) - it has equal speed, and inferior maneuverability (Onslaught's engine array gives much better torque, though the ship is heavier)
a modern titan making good use of its rear gun (and of course the onslaught is going to decide to launch a volley of torpedoes right now, killing both ships)
a modern (hasslenought) version of the titan, and a modified titan for a planned mission [note the industrial cutter lasers: they look like large mining lasers]
and in comparison with the panther
I have several balanced versions of the titan, though no pics of them uploaded.
