Way way way way back when GW first did Attack Craft models for BFG, they had two different models for Imperial Fury fighters (Type 1, Type 2). I believe they ditched the Type 2 design after a couple of years. Type 1 is the leftmost (in the Blue Book, you'll see the Type 1 fighters used on the massive space dock scratchbuild on page 62, and the Type 1 and Type 2 fighters used on the Imperial Blackstone Fortress modification on page 61), Type 2 is second from the left. Imperial Starhawk bombers are in the middle. Chaos Swiftdeath fighters are second from the right. Chaos Doomfire bombers are on the right. The only thing you're missing are Imperial Shark Assault boats, and possibly Torpedoes and Mines, if they're something you care about.
Edit: come to think of it, the Imperial Blackstone Fortress conversion also shows a third fighter style, but I suspect that might have been a modeler's scratchbuild, as I've never seen that particular design (long straight noses, stubby square wings, wingtips possibly folded up) anywhere else in GW's product line.
