The four Hornets deployed on Operation Slipper (OEF) were early HUG 2.0 jets and as such need all the external upgrades you see on the jets today (birdslicers, swept antennas, GPS dome etc). The best way to achieve this is with the new Wolfpack Designs F/A-18+ coversion or the MAW Decals equivalent.
