Stormhawk class prototype battlecruiser [Casca1967]

I hesitate to ask this, I KNOW I posted a request before but I cannot find it now.

The Stormhawk is a prototype, one of a kind starship. She is a battlecruiser, smaller than a TOR Star Destroyer, but with comparable weapons. She is also much faster and more maneuverable. Oh and she has a cloaking device!

After the Sacking of Coruscant the Stormhawk went renegade, fighting the Sith anywhere and everywhere she could. The common spacers of the Sith fleet think she is some kind of cross between 'the flying Dutchman' and a rider of the Apocalypse. When she appears, Sith ships die, then she vanishes again. She has a number of odd allies and she figures prominently in my fanfictions.

In form, she has been described as a Hammerhead class cruiser (http://starwars.wikia.com/wiki/Hammerhead-class_cruiser), the bit from the engines forward, melded to a carrier (something like this maybe http://starwars.wikia.com/wiki/Escort_carrier)in back with four HUGE engines at the back. I have essentially left it open to interpretation for everything else.

The only stipulation is that there has to be a VERY big gun on the front, a bit underneath the bridge viewport. The main gun of the Stormhawk is a plasma cannon and can punch a hole in any ship that is not designed specifically to prevent such attacks. Sith dreadnoughts are not. Enough said.
