C-130A Hercules

The Hercules, initially designed to specifications laid down by the USAF Tactical Air Command, first flew as the YC-130 in August 1954. The initial production model was the C-130A, with four Allison T56-A-11 or -9 turboprops. Conceptual studies of the C-130A, were initiated in 1951. The first prototype flight took place in 1954 and the first production flight followed on April 7, 1955. A total of 219 were ordered and the C-130A joined the U.S. Air Force inventory in December 1956. Two DC-130A's (originally GC-130A's) were built as drone launchers/directors, carrying up to four drones on underwing pylons. All special equipment was removable, permitting the aircraft to be used as freighters, assault transports, or ambulances. Early C-130A, B, and D versions are now retired.
