The design for the Thunderskiffs is quite ingenious. They are a blend between gunships and shuttles. They have a large bay for troops and equipment that can be deployed quickly to the surface and removed from a hot zone just as fast.
The armament is X32 Grayhound autocannons that can switch between 12mm rounds for ground support and 48mm rounds for ship-to-ship engagement. To top it off they are armored with heavy 7-inch composite plating and equipped with FTL drives.
All of this gear slows down Thunderskiffs a bit, however they are fast enough to avoid most larger craft but can be engaged by fighters and interceptors easily.
