C-130B Hercules

The C-130B introduced Allison T56-A-7 turboprops and the first of 134 entered Air Force service in April-June 1959. The B model carries additional fuel in the wings, and has upgraded engines and strengthened landing gear. C-130B's are used in aerial fire fighting missions by Air National Guard and Air Force Reserve units. Six C-130B's were modified in 1961 for snatch recovery of classified U.S. Air Force satellites by the 6593rd Test Squadron at Hickam Air Force Base, Hawaii. Early C-130A, B, and D versions are now retired.
