The last production run of the Z-95 before the development of the X-Wing, the AF4 is a modern craft, capable of dishing out almost as much punishment as it's younger sibling. As fast atmosphericly as the T65B, it is not quite so favorably equipped for vacuum operations, were it is only as fast as the Y-Wing. This marks a full circle in the Z-95 series, with the original Mark 1's having been optimized for atmospheric operations
The traditional, anemic triple blasters have been replaced with real laser cannons, and the old concussion missile launcher has been replaced with a universal missile/bomb bay. This later has proven to be very popular with mercenary and militia units, as you can use pretty much whatever you've been able to get your hands on.
Produced only a few years ago, it is still possible to find Z-95AF4's in the factory wrappings. But one must hunt awfully hard for those. And forget finding them on the second-hand market. Those folks who were able to buy AF4's are hanging on to them. Even if they are being replaced with more modern designs in front line units, they usually retained for reserve forces. Those that fly the Z95AF4 are almost always good enought to get everything they can out of the craft. You usually won't get a second chance.
