To answer some questions. The AMT kit would have worked great for the second design thats floating around. It looks more like a modifide Star Destroyer having the same surface decks and control tower. The design I chose was that of a new ship sharing only the substructer. You could build it from the kit but and that was one option I concidered. With every project I start I try to set goals and new chalenges for myself. In this build it was to go 100% scratch and use no kit parts or I'm just sick...Still trying to figure that out???
The engine bells could be robbed from the kit if needed but I wanted to build them. To form over them would increase the diameter and would not look right or fit correctly.
The Interdictor does not have much in the way of offensive weapons aside from the gravity well projectors and is limited to turbo laser emplacements on the surface. Think of it as a submarine. A subs primary objective is a weapons delivery system. They will engage in battle if needed however have a better advantage on the perimeter. The Interdictor will travel the perimeter of the battle zone where it has a clear view of the battle and pinpoint the most accurate location to generate a gravity well.
Thanks for the great questions and stimulating evaluation. This is exactly why I love this forum.
