So, while I'm rapidly creating an app, I'm curious.

It's a basic ship idea, that I was kinda surprised it wasn't included. A super heavy artillery ship. The ship itself is about a kilometer. The length of the cannon that runs through it is about 5 kilometers. Relegated to HSR3, as its firepower is compensated with the lack of space for armor. Only armed with point defense, and two medium turrets normally found on Light cruisers to fend off pirates. Most of the remaining space is taken up by engines and forward thrusters. It's speed is nothing to laugh at, although its turning rate is....rather lacking.

Generally hangs back, further than even a carrier, and probably has the unofficial nickname "Battleship Killer" or "Planet Lance" on account of its appearance.
