Book Description
This is the third in a series of research studies—historical works that were not published for various reasons. Yet, the material contained therein was deemed to be of enduring value to Air Force members and scholars. These were minimally edited and printed in a limited edition to reach a small audience that may find them useful. We invite readers to provide feedback to the Air Force History and Museums Program.The author, Marcelle S. Knaack, a member of the Office of Air Force History, undertook the research and writing of this book as a consultant, after she retired. Tragically, she passed away in November 1996, before she completed the manuscript. Her colleague, Bernard C. Nalty, also retired by that time, undertook to complete Ms. Knaack's work.At first glance, the history of the C–5A Galaxy seems to be nothing more than a compilation of contradictions. Ordered under a totally new procurement concept specifically designed to control costs, the C–5A aircraft ended up costing a small fortune. Its purchase in 1965 depended on achieving an initial operational capability no later than 1969, but the transport did not appear in South Vietnam in a truly operational capacity until August 1971. Although built by the Lockheed-Georgia Company, celebrated for its success with military transports like the C–130 Hercules and C–141 Starlifter, the C–5A program from the verystart encountered serious technical problems, delays, and exorbitant cost overruns, which combined to trigger several congressional investigations.Although the program contracted in size under the pressure of these failings, it survived congressional opposition and began to demonstrate its unique value during the last year of the Vietnam War, even though operating under weight restrictions. In October 1973, moreover, the C–5A helped provide Israel with a constant flow of supplies to ensure victory over the attacking Egyptian and Syrian armies.Into the 1980s the C–5A operated under increasingly stringent flying restrictions because the flawed wing structure deteriorated until it had to be replaced. While under these restrictions, the C–5A could carry just 174,000 pounds of cargo, roughly 100,000 pounds more than the C–141, but 46,000 pounds less than the Galaxy's design objective. Although installation of the heavier new wing would probably prevent the airplane from ever attaining the design capacity of 220,000 pounds, the Military Airlift Command was determined to extend the service life of the C–5A because its performance remained so impressive even with a reduced load.The improvements that strengthened the structure of the C–5A were incorporated in a new version of the Galaxy, the C–5B, for which Lockheed-Georgia reopened its production line. The modified A-model and the new C–5B did everything expected of a heavy-logistics transport during the Persian Gulf War of 1990-1991.

Book Description
In response to a congressional request, GAO evaluated the Air Force's analysis leading to its decision to develop and produce the C-17 aircraft rather than buy additional C-5 aircraft for its long-range airlift needs, specifically: (1) its airlift requirements and capabilities; (2) the alternatives it considered to alleviate the airlift shortfall; and (3) the criteria and assumptions it used to evaluate the alternatives. GAO noted that: (1) in 1983, the Air Force concluded that the C-17 aircraft was the most cost-effective way for it to meet its airlift requirements; (2) the Air Force has continued research and development on the C-17 and has obligated almost $600 million for the program; and (3) in 1987, the Air Force received an initial $50 million to produce the C-17 and, over the next 5 years, plans to request about $14 billion to develop and buy it. GAO found that: (1) lower operating and support costs could more than offset higher C-17 acquisition costs, resulting in lower C-17 life-cycle costs than the C-5 alternative; (2) the C-5 cannot match the expected C-17 capability to land and operate at a wide range of airfields closer to the battle area; (3) the C-17 alternative could require about 12,900 fewer personnel than the C-5 alternative; (4) the C-5 alternative could allow the Air Force to increase its airlift capability more quickly, since the C-5 is already in production and the first C-17 would not be ready until 1990; (5) if the Air Force continues with the C-17 program, its costs will probably exceed its estimates by about $2.3 billion; and (6) if the Air Force selects the C-5, it would need an additional $3.6 billion over its estimated costs.

Book Description
A total of 213 C-17s have been procured through FY2009, including eight that were procured in the FY2009 supplemental appropriations act (H.R. 2346/P.L. 111-32 of June 24, 2009). The Administration's proposed FY2010 defense budget proposes to end C-17 procurement and does not request any funding for the procurement of additional C-17s. The Administration argues that enough C-17s have now been procured to meet future operational needs. Supporters of procuring additional C-17s in FY2010 believe additional C-17s will be needed to meet future operational needs. The issue of how much airlift capability will be needed in the future is currently being examined in a congressionally mandated study being done by the Institute for Defense Analyses (IDA) and in a separate Department of Defense (DOD) study called the Mobility Capabilities and Requirements Study 2016 (MCRS-16), which is due to be completed by the end of 2009. FY2010 defense authorization bill: The House and Senate Armed Services Committees, in their markups of the FY2010 defense authorization bill (H.R. 2647/S. 1390), recommended no funding for the procurement of additional C-17s. Section 134 of H.R. 2647 would require the Secretary of the Air Force, in coordination with the Director of the Air National Guard, to submit to the congressional defense committees, at least 120 days before a C-5 airlift aircraft is retired, a report on the proposed force structure and basing of C-5 and C-17 aircraft. Section 135 of H.R. 2647 would amend 10 USC 8062(g)(1) to state that, effective October 1, 2009, the Secretary of the Air Force shall maintain a total inventory of C-5s and C-17s of not less than 316 aircraft. Assuming the retention of the current force of 111 C-5s, this provision would appear to support a C-17 force of 205 C-7s' the number procured through FY2008.
