Marines AV-8B Harrier jet and MV-22 Osprey aircraft from USS Bataan get refueled by KC-130s from Sigonella airbase.
The following video shows fixed-wing and rotary-wing aerial refueling exercise, involving AV-8B and MV-22s, over the Mediterranean Sea with Special Purpose Marine Air- Ground Task Force (SP-MAGTF) Crisis Response KC-130s in June 2014.
Interestingly, the Harrier carries a single GBU-12 500-lb LGB (Laser Guided Bomb) on the right hand underwing pylon. The bomb seems to be marked with a yellow stripe (barely visible, painted on the olive drab color aft of the front guidance kit) which indicates the presence of explosive: in other words, it’s not an inert weapon.
The reason for carrying live ordnance is unknown. Most probably the aircraft were armed and ready to provide support to the evacuation of the U.S. embassy in Tripoli, which eventually took place on Jul. 26 amid continuing clashes between rival militias.
