Space is also not empty, black holes, stars, comets, meteorites, planets, dust, ice, etc occupy space, if something was to be fired from point A to point B in place it would have to overcome the potential of gravitational forces from objects larger than it or the possibility of hitting debris.
as for the gun, the class of ship was a Dominator, I had the dimensions of the gun wrong however, the gun is called a Nova cannon, it is just over half a kilometre in length and the reason the ship is so undesirable is because of it's size, it has to be so big because the recoil of the gun would destroy any other ship smaller than it if the gun was mounted to it. Basically it if slow to move and is a huge target.
Now the actual gun fires a variety of different shell types and uses a series magnetic accelerators to launch the shell from ship at a speed that is a fraction of the which light travels, then it is accelerated even further with gravmetric coils as it travels through space. The actual shells themselves are all 50 meters in diameter, teams of slaves and slave drivers work to reload this weapon using cranes and work vehicles while the generators of the magnetic accelerators charge up.
An explosion the size of a small planet, blah blah blah.
Nobody likes it though because despite the power of the gun it is slow, clumsy, inaccurate, sucks at close range and paints a huge target on your forehead when your in the ship with this thing mounted on the front.
Also the Moonstone cannon from Skies of Arcadia ain't got nothing on a gun that rips temporary black holes into space.
