The original Starlifter model, designated C-141A, could carry 154 passengers, or 80 litters for wounded with seating for 16. A total of 284 A-models were built. The C-141A entered service in April 1965. It was soon discovered that the aircraft's volume capacity was relatively low in comparison to its lifting capacity; it generally ran out of physical space before it hit its weight limit. The C-141A could carry ten standard 463L master pallets and had a total cargo capacity of 62,700 lb (28,900 kg). It could also carry specialized cargoes, such as the Minuteman missile.
