The F-100C Super Sabre fighter-bomber was the first fully combat-capable version of the Super Sabre, and was the first version of the Super Sabre to serve with the USAF in really large numbers.The F-100C had provision for single-point ground refueling, a major improvement over the gravity-filling of the fuselage tanks in the F-100A. A wing-mounted detachable refuelling probe was added which made the F-100C capable of in-flight refuelling.
