SilverWolf Aerospace adds several parts to the Mk3 system for command, aerodynamic, and structural categories. Three cockpits have been added for specific markets: one for subsonic transports, another for supersonic transports, and a third for hypersonic spaceplanes. Two tail connectors have also been provided as an alternative to the cargo ramp and engine mounts, adding some aesthetic for aircraft. Both tail connectors are equipped with APUs for converting IntakeAir and LiquidFuel into electricity. Finally, wing boxes and fairings have been introduced for supporting larger wing assemblies further below the body of the aircraft.
