1: Big C is 6km long and fits 12 lucifers. I have the colossus video right here in avi format and playing right now.
and 2: I don't mind posting your giant ships, this thread IS about the largest ships.
And guys, I'll be modeling my 12km long ship called the Eternity soon. If I get better at coding, it will definately replace the Big C, I would love to see a Sathanas try to beat that! Though I don't like bragging, when I was creating my TC storyline it included the creation of a new armor called Firestorm. Firestorm is a metal created by energy, as unusual as it seems the scientists managed to reverse Einstien's formula of E=mc2 to create mass from energy. This new metal is unlike anything before it. Firestorm is completely immune to energy weapons (but the hull under the armor is still affected by the heat dispersion) and highly resistant to projectiles and the Eternity is completely plated by this metal making it almost undefeatable.
Before this becomes a physics arguement, my storyline is fiction and nothing more and it is all made up. But even with that nearly invurnerable armor... well read the story:
Several enemy ships broke through the line of fire and accelerated towards the eternity at ramming speed. Normally one wouldn't have a chance at moving the massive Eternity but 32 broke through and combined their power and rammed the Eternity into planet Lagra's gravitational field and the Eternity, despite its full engines power, was pulled into the atmosphere. Admiral Mason knew his ship was going down but he wasn't dead yet. He ordered his pilot and navigator to have the Eternity crash land as flatly as possible. If the massive ship landed at an angle it would snap in half but luckily the pilot succeeded in crashing flatly. --- skipping ahead --- Thrusting all power to repulsar drives, the Eternity managed to get off the ground and started its accent. Mason watched his ship rise in his panel's monitor. They left a camera on the ground when they retreated back to the ship and Mason wanted to keep the recording even though he wanted to forget the events that transpired on the surface. As he watched the video he saw what remained of the Eternity's lower hull. Though most of the armor didn't fall off the under hull was completely shattered.
So given the mass of the ship, the speed of reentry, and the force of the impact combined destroyed the armor. ok, back on track.
