Such training missions are routinely flown to give the Typhoon pilots the opportunity to perform multiple plugs with the tanker’s hose and practice for real operations. “Dry plugs” are connections during which no fuel is pumped from the tanker, as opposed to “wet plugs” when the receiver gets fuel. During Operation Unified Protector in Libya, KC-130Js operating from Pisa refuelled the Italian Typhoons deployed to Trapani tasked with HVAA (High Value Air Asset) escort and DCA (Defensive Counter Air) missions.
