From: jt@cunixa.cc.columbia.edu (James Tuller) The C-141 was ordered in 1961 with the same 10' x 9' cross-section as the C-130. Lockheed built 284. It was found that the plane often ran out of space before it ran out of lift, so 280 of them were extended by 23', the revised aircraft designated as C-141B. The last of these was delivered in 1982. Payload is 94,000 lb., range with max payload is 2,935 mi. The C-5 evolved from the Heavy Logistic Specification of 1963, and the first aircraft flew in 1968. There are just over 100 C-5A and C-5B aircraft. They are hard to distinguish externally. 77 of the original 81 C-5A's survived to 1982, when the C-5B was developed. The B first flew in 1985. Many of the C-5B's improvements were retrofitted to the C-5A. The deck width is 19', payload is 291,000 lbs for the B, 221,000 for the A. Range with maximum load is 2,700 miles; with maximum fuel it is 6,850 miles.
