The Boeing (formerly McDonnell Douglas) C-17 Globemaster III is a large American airlifter manufactured by Boeing Integrated Defense Systems. The C-17 is operated by the United States Air Force, the British Royal Air Force, the Royal Australian Air Force, and the Canadian Forces, [http://www.boeing.com/defense-space/military/c17/news/2007/q3/070808c_nr.html "Boeing Delivers Canada's First C-17"] ] while NATO and Qatar have placed orders for the airlifter.

The C-17 Globemaster III is used for rapid strategic airlift of troops and cargo to main operating bases or forward bases anywhere in the world. It has the ability to rapidly deploy a combat unit to a potential battle area and sustain it with on-going supplies. The C-17 is also capable of performing tactical airlift, medical evacuation and airdrop missions. [http://www.af.mil/factsheets/factsheet.asp?fsID=86 C-17 fact sheet, US Air Force] ] The aircraft carries on the name of two previous United States cargo aircraft, the C-74 Globemaster and the C-124 Globemaster II.

Development

Background

In the 1970s, the US Air Force began looking for a replacement for the C-130 Hercules tactical airlifter. The Advanced Medium STOL Transport (AMST) competition was held, with Boeing proposing the YC-14, and McDonnell Douglas proposing the YC-15. Despite both entrants exceeding specified requirements, the AMST competition was canceled before a winner had been selected.Kennedy 2004, p. 3-20.]

By the early 1980s, the USAF found itself with a large fleet of aging C-141 Starlifter cargo aircraft. Some of the C-141s had major structural problems due to heavy use. Compounding matters, USAF historically never possessed sufficient strategic airlift capabilities to fulfill its airlift requirements. In response, McDonnell Douglas elected to develop a new aircraft using the YC-15 as the basis. McDonnell Douglas was awarded a contract to build its proposed aircraft, by then designated the C-17A Globemaster III, on August 28, 1981. The new aircraft differed in having swept wings, increased size, and more powerful engines. This would allow it to perform all work performed by the C-141, but to also fulfill some of the duties of the C-5 Galaxy, freeing the C-5 fleet for larger outsize cargo.

Design phase

Development continued until December 1985 when a full-scale production contract was signed for 210 aircraft. Development problems and limited funding caused delays in the late 1980s. [ [http://rtoc.ida.org/rtoc/open/briefings_articles/kennednd.pdf Historical Realities of C-17 Program] ] Questions were also raised about more cost-effective alternatives during this time. In April 1990, Defense Secretary Dick Cheney reduced the order from 210 to 120 aircraft. The C-17's maiden flight was on September 15, 1991 from the McDonnell Douglas west coast plant in Long Beach, California, about a year behind schedule. [http://www.fas.org/sgp/crs/weapons/RL30685.pdf CRS Report for Congress. Military Airlift: C-17 Aircraft Program] ] This aircraft (T-1) and five more production models (P1-P5) participated in extensive flight testing and evaluation at Edwards AFB. In late 1993, the DoD gave the contractor two years to solve production and cost overrun problems or face termination of the contract after the delivery of the fortieth aircraft. By accepting the 1993 terms, McDonnell Douglas incurred a loss of nearly US$1.5 billion on the development phase of the program.

In April 1994, the C-17 program was still experiencing cost overruns, and did not meet weight, fuel burn, payload and range specifications. Airflow issues caused problems with parachutes and there were various other technical problems with mission software, landing gear, etc. [ [http://archive.gao.gov/t2pbat3/151473.pdf GAO Testimony before the SubCommitte on Military Acquisition] ] A July 1994 GAO document revealed that to justify investing in the C-17 rather than in the C-5, Air Force and DoD studies from 1986 and 1991 had claimed that the C-17 could use 6,400 more runways (outside the US) than the C-5. It was later discovered that this study had only considered the runway dimensions, but not their strength or Load Classification Numbers (LCN). The C-5 has a lower LCN than the C-17, although the US Air Force places both in the same broad Load Classification Group (LCG). When considering runway dimensions and their load ratings, the C-17's worldwide runway advantage over the C-5 shrank from 6,400 to 911 airfields. [http://archive.gao.gov/t2pbat3/152088.pdf GAO Comparison of C-5 and C-17 Airfield Availability] ] However, the C-17's ability to use lower quality, austere airfields was not considered.

A January 1995 GAO report revealed that while the original C-17 budget was US$41.8 billion for 210 aircraft, the 120 aircraft already ordered at that point had already cost US$39.5 billion. [ [http://www.gao.gov/archive/1995/ns95026.pdf C-17 Cost and Performance Issues] ] In March 1994, the U.S. Army had decided it no longer needed the 60,000 lb (27,000 kg) Low Altitude Parachute Extraction System (LAPES) delivery that the C-17 was supposed to provide, feeling that the 42,000 lb (19,000 kg) capability of the C-130 Hercules was sufficient. It was decided not to conduct C-17 LAPES training beyond the testing of a 42,000 lb (19,000 kg) LAPES delivery. There were still airflow problems making it impossible for the C-17 to meet its original airdrop requirements. A February 1997 GAO Report revealed that a C-17 with a full payload could not land on 3,000 feet (900 m) wet runways, for simulations suggested 5,000 ft (1,500 m) was required. [ [http://www.gao.gov/archive/1997/ns97050.pdf C-17 Globemaster Support of Operation Joint Endevour] ]

By the mid-1990s, most of the problems had been resolved. [ [http://www.afa.org/media/press/windall.asp Air Force Secretary Says Modernization, C-17 on Track] , Air Force magazine, September 19, 1995.] The first C-17 squadron was declared operational by the U.S. Air Force in January 1995. In 1996, DoD ordered another 80 aircraft for a total of 120. In 1997 McDonnell Douglas merged with its former competitor, Boeing. In 1998, the order was increased to 134 units and in August 2002 to 180.

Recent developments

In July 2006, C-17 production was planned to end in 2009 unless Boeing received additional orders in time to allow the production pipeline to remain in operation. At the time a large follow-on order would allow Boeing to begin C-17B production in 2010. The proposed C-17B would be capable of landing on sandy beaches and other areas off-limits to the C-17A.cite web |url=http://online.wsj.com/article/BT-CO-20060719-713127.html |title= Denmark Signs Up For Boeing C-17 In NATO Deal |last= Christie |first= R. |date= July 19, 2006 |publisher= The Wall Street Journal |archiveurl=http://web.archive.org/web/20061016003710/http://online.wsj.com/article/BT-CO-20060719-713127.html |archivedate=2006-10-16.]

On August 18, 2006 Boeing announced it was telling suppliers to stop work on parts for uncommitted C-17s. This move is the first step in shutting down production if no new plane orders were received from the US Government. [ [http://boeing.com/news/releases/2006/q3/060818e_nr.html Boeing preparing to end C-17 production] ] However, just one month later on September 21, a House and Senate conference committee approved a US$447 billion defense bill for 2007, that includes US$2.1 billion for 10 additional C-17s. The additional purchase follows intense lobbying by Boeing, as well as by California state leaders (where the plane is manufactured), and Missouri leaders, where Boeing's defense business is based. [ [http://aimpoints.hq.af.mil/display.cfm?id=13988 "Boeing's C-17 line wins a reprieve on new funding"] , US Air Force ] However, this extends the life of the program for only one additional year, to 2010.

On March 2 2007, Boeing announced the C-17 production line may end in mid-2009 due to the lack of additional US government and international orders. [ [http://www.boeing.com/news/releases/2007/q1/070302a_nr.html Boeing Announces C-17 Line May End in mid-2009; Stops Procurement of Long-lead Parts] , Boeing]

A total of 190 C-17s are contracted for delivery to the USAF as of October 2007. Boeing has purchased parts for 30 new C-17s at its own expense in hopes that Congress will approve the funds requested. [ [http://www.boeing.com/defense-space/military/c17/c17news.html Boeing Company Funds Extension] , Boeing, web page revised 9 July 2008.] Fifteen C-17s are earmarked in a FY2008 War Supplemental [ [http://www.armscontrolcenter.org/policy/securityspending/articles/analysis_c110_senate_may_supp/ Analysis of Senate May 2008 Iraq-Afghanistan Supplemental War Funding for DOD] , Center for Arms Control and Non-Proliferation, 21 May 2008.] that passed the House on 10 June 2008 and the Senate on June 27, 2008. President Bush signed the measure into law in 30 June 2008. [ [http://www.defenselink.mil/news/newsarticle.aspx?id=50356 "Bush Signs $162 Billion Supplemental War Funding Bill"] , US DoD, 30 June 2008.] These funds will extend production from August 2009 to August 2010 and the total number of C-17s on contract will be 205, once a contract is awarded.

Design

In recent years the size and weight of U.S. mechanized firepower and equipment have grown, which has significantly increased air mobility requirements, particularly in the area of large or heavy outsize cargo. The C-17 can airlift such cargo fairly close to a potential battle area.

The C-17 is powered by four fully reversible, F117-PW-100 turbofan engines (the Department of Defense designation for the commercial Pratt and Whitney PW2040, currently used on the Boeing 757). Each engine is rated at 40,400 lbf (180 kN) of thrust. [http://www.pw.utc.com/vgn-ext-templating/v/index.jsp?vgnextrefresh=1&vgnextoid=4d9f0030296eb010VgnVCM1000000881000aRCRD Pratt & Whitney's F117 page] ] The thrust reversers direct the flow of air upward and forward. This reduces the probability of foreign object damage and provides reverse thrust capable of backing the aircraft. Additionally, the C-17's thrust reversers can be used in flight at idle-reverse for added drag in maximum-rate descents.

The aircraft requires a crew of three (pilot, copilot, and loadmaster) for cargo operations. Cargo is loaded through a large aft door that accommodates both rolling stock (trucks, armored vehicles, trailers, etc.) and palletized cargo. The cargo floor has rollers (used for palletized cargo) that can be flipped to provide a flat floor suitable for rolling stock. One of the larger pieces of rolling stock that this aircraft can carry is the 70-ton M1 Abrams tank.

Maximum payload capacity of the C-17 is 170,900 lb (77,500 kg), and its maximum gross takeoff weight is 585,000 lb (265,350 kg). With a payload of 160,000 lb (72,600 kg) and an initial cruise altitude of 28,000 ft (8,500 m), the C-17 has an unrefueled range of approximately 2,400 nautical miles (4,400 km) on the first 71 units, and 2,800 nautical miles (5,200 km) on all subsequent units -- which are extended-range models using the sealed center wing bay as a fuel tank. These units are informally referred to by Boeing as the C-17 ER." [http://www.boeing.com/commercial/airports/arff/arffc17.pdf C-17/C-17 ER Flammable Material Locations] ." Boeing Integrated Defense Systems. May 1, 2005.] The C-17 cruise speed is approximately 450 knots (833 km/h) (0.76 Mach). The C-17 is designed to airdrop 102 paratroopers and their equipment.

The C-17 is designed to operate from runways as short as 3,500 ft (1,064 m) and as narrow as 90 ft (27 m). In addition, the C-17 can operate out of unpaved, unimproved runways (although there is the increased probability of damage to the aircraft). The thrust reversers can be used to back the aircraft and reverse direction on narrow taxiways using a three-point (or in some cases, multi-point) turn maneuver.

Operational history

United States Air Force

The first production model was delivered to Charleston Air Force Base, South Carolina on July 14, 1993. The first squadron of C-17s, the 17th Airlift Squadron, was declared operationally ready on January 17, 1995.Norton 2001, p. 94-95.] The C-17 has broken 22 records for oversized payloads. [ [http://www.boeing.com/defense-space/military/c17/news/2001/q4/nr_011128n.htm Boeing: Boeing C-17 Globemaster III Claims 13 World Records] , Boeing] The C-17 was awarded US aviation's most prestigious award, the Collier Trophy in 1994. [ [http://www.naa.aero/html/awards/index.cfm?cmsid=150 Collier Trophy, 1990-1999 winners] , NAA: National Aeronautic Association] ]

The Air Force originally programmed to buy a total of 120 C-17s, with the last one being scheduled for delivery in November 2004. The fiscal 2000 budget funded another 14 aircraft, primarily for Air Mobility Command support of the U.S. Special Operations Command (USSOCOM). Basing of the original 120 C-17s was with the 437th Airlift Wing and 315th Airlift Wing at Charleston AFB, South Carolina, the 62nd Airlift Wing and 446th Airlift Wing at McChord Air Force Base, Washington (first aircraft arrived in July 1999), the Air Education and Training Command's (AETC) 97th Air Mobility Wing at Altus AFB, Oklahoma, and the Air Mobility Command-gained 172d Airlift Wing of the Mississippi Air National Guard at Jackson-Evers International Airport/ANGB, Mississippi.

Basing of the additional 13 aircraft went to McGuire Air Force Base, New Jersey, Elmendorf Air Force Base, Alaska, Hickam Air Force Base, Hawaii, and Travis Air Force Base, California. An additional 60 units were ordered in May 2002.

In FY 2006, eight C-17s were delivered to March ARB, California. Although operationally-gained by the Air Mobility Command, these C-17s are the only aircraft strictly under direct control of the Air Force Reserve Command (AFRC).

In 2007, Congress appropriated funds for 10 additional USAF C-17s, [ [http://thomas.loc.gov/cgi-bin/query/z?c109:H.R.5631.enr: Search Results - THOMAS (Library of Congress) ] ] bringing the total planned fleet size (on order + delivered) to 190. Additional aircraft were subsequently assigned to Dover AFB, Delaware.

The C-17 was used to deliver military goods and humanitarian aid during Operation Enduring Freedom in Afghanistan as well as Operation Iraqi Freedom in Iraq. On March 26, 2003, fifteen USAF C-17s participated in the biggest combat airdrop since the United States invasion of Panama in December, 1989: the night-time airdrop of 1,000 paratroopers from the 173rd Airborne Brigade occurred over Bashur, Iraq. It opened the northern front to combat operations and constituted the largest formation airdrop carried out by the United States since World War II.

USAF C-17s have also been used to assist US Allies transport military equipment. This has included the transportation of Canadian armored vehicles to Afghanistan in 2003 and the redeployment of Australian forces in Australia and the Solomon Islands during the Australian-led military deployment to East Timor in 2006. In late September and early November 2006, USAF C-17s flew 15 Canadian Forces Leopard C2 tanks from Kyrgyzstan into Kandahar AF in support of the Afghanistan NATO mission.

There has been debate regarding follow-on orders for the C-17, with the Air Force requesting line shutdown, and members of Congress attempting to reinstate production. Furthermore, in FY2007, the Air Force requested $1.6 billion to deal with what it termed "excessive combat use" on operational airframes.Fulghum, D., Butler, A., Barrie, D.: "Australia Picks C-17." "Aviation Week & Space Technology". March 13, 2006, page 43.

However, in testimony before a House of Representatives subcommittee on air and land forces, General Arthur Lichte, USAF, the commander of Air Mobility Command indicated extending production to another 15 aircraft, bringing the total to 205. Pending on the delivery of the results of two studies in 2009, Lichte opines that the Air Force may eventually have to keep the production line open for purchase of even more C-17s to satisfy airlift requirements.

Royal Air Force

Boeing has actively marketed the C-17 to many European nations including Belgium, Germany, France, Italy, Spain and the United Kingdom. Of these, the UK was always seen as the most likely customer given its increasingly expeditionary military strategy and global commitments. The Royal Air Force has established an aim of having interoperability and some weapons and capabilities commonality with the United States Air Force. The UK's 1998 Strategic Defence Review identified a requirement for a strategic airlifter. The Short-Term Strategic Airlift (STSA) competition commenced in September of that year, however tendering was canceled in August 1999 with some bids identified by ministers as too expensive (including the Boeing/BAe C-17 bid) and others unsuitable.cite news|first = Dominic|last = O'Connell|title = Political clash haunts MoD deal decision|work = The Business|publisher = Sunday Business Group|date= 1999-12-05|accessdate = 2007-02-07] The project continued, with the C-17 seen as the favorite. The UK Defence Secretary, Geoff Hoon, announced in May 2000 that the RAF would lease four C-17s at an annual cost of £100 million from Boeing for an initial seven years with an optional two year extension. At this point the RAF would have the option to buy the aircraft or return them to Boeing. The UK committed to upgrading the C-17s in line with the USAF so that in the event of their being returned to Boeing the USAF could adopt them.

The first C-17 was delivered to the RAF at Boeing's Long Beach facility on May 17, 2001 and flown to RAF Brize Norton by a crew from No. 99 Squadron which had previously trained with USAF crews to gain competence on the type. The RAF's fourth C-17 was delivered on August 24, 2001. The RAF aircraft were some of the first to take advantage of the new center wing fuel tank.

The RAF declared itself delighted with the C-17 and reports began to emerge that they wished to retain the aircraft regardless of the A400M's progress. Although the C-17 fleet was to be a fallback for the A400M, the UK announced on July 21, 2004 that they have elected to buy their four C-17s at the end of the lease, even though the A400M is moving towards production. They will also be placing a follow-on order for one aircraft, though there may be additional purchases later. [http://www.global-defence.com/2003/globe_master.htm "RAF's Globe Master] ." "Global Defence Review". 2003.] While the A400M is described as a "strategic" airlifter, the C-17 gives the RAF true strategic capabilities that it would not wish to lose, for example a maximum payload of 169,500 lb (77,000 kg) compared to the Airbus' 82,000 lb (37,000 kg).

The Ministry of Defence (MoD) announced on August 4, 2006 that they had ordered an additional C-17 and that the four aircraft on lease will be purchased at the end of the current contract in 2008. The fifth aircraft was delivered on February 22, 2008 and reported for duty on April 7, 2008 at Brize Norton air base in Oxfordshire. [ [http://www.flightglobal.com/articles/2008/04/07/222815/pictures-uk-receives-fifth-c-17-as-raf-fleet-passes-40000-flight.html "UK receives fifth C-17, as RAF fleet passes 40,000 flight hours"] . "FlightGlobal.com" April 14 2008.] Due to fears that the A400M may suffer further delays, the MoD is planning to acquire three more C-17s (for a total of eight) for delivery in 2009-2010, provided that the U.S. Air Force places a follow-on order extending through the same time period.Robertson, D.

December 28, 2006.] On July 26 2007, Defence Secretary Des Browne announced that the MoD intends to order a sixth C-17 to boost operations in Iraq and Afghanistan. [http://www.mod.uk/DefenceInternet/DefenceNews/EquipmentAndLogistics/BrownePurchaseOfExtraC17WillsignificantlyBoostUkMilitaryOperations.htm "Browne: Purchase of extra C-17 will 'significantly boost' UK military operations"] . UK Ministry of Defence news, July 27, 2007.] On December 3 2007, the MoD announced a contract with Boeing for a sixth C-17, [ [http://www.mod.uk/DefenceInternet/DefenceNews/EquipmentAndLogistics/RafGetsSixthC17Globemaster.htm "RAF gets sixth C-17 Globemaster"] , UK Ministry of Defence news, 4 December 2007.] which was handed over to the RAF on June 11, 2008. [ [http://www.boeing.com/news/releases/2008/q2/080611c_nr.html "Boeing Delivers 6th C-17 to Royal Air Force"] , Boeing, June 11, 2008.]

In RAF service the C-17 has not been given an official designation (e.g. C-130J referred to as Hercules C4 or C5) due to its leased status, but is referred to simply as the C-17. Following the end of the lease period the four aircraft will assume an RAF designation, most likely "Globemaster C1".

Royal Australian Air Force

The Royal Australian Air Force (RAAF) began investigating options to acquire heavy lift transport aircraft for strategic transport in 2005.cite journal|last=McLaughlin|first=Andrew|date=2008|title=Big Mover|journal=Australian Aviation|publisher=Phantom Media |location=Canberra|volume=September 2008|pages=pp.40–41] In late 2005 the then Minister for Defence Robert Hill stated that the Australian Defence Force was considering such aircraft due to the limited availability of strategic airlift aircraft from partner nations and air freight companies. The C-17 was considered to be favoured over the A400M as it was a "proven aircraft" and was already in production. One major requirement from the RAAF was the ability to airlift the Army's new M1 Abrams main battle tanks; another requirement was immediate delivery. Though unstated, commonality with the USAF and the United Kingdom's RAF was also considered advantageous. The aircraft for the RAAF were ordered directly from the USAF production run, and are identical to American C-17 even in paint scheme, the only difference being the national markings. This allowed delivery to commence within nine months of commitment to the program."Stock Standard." "Aviation Week & Space Technology. December 11 2006.]

On March 2, 2006 the Australian Government announced the purchase of three aircraft and one option with an entry into service date of 2006. The Australian Government's 2006–07 budget included funding of A$2.2 billion to fund the purchase of three or four C-17s and related spare parts and training equipment.

Australia's C-17s have supported ADF operations around the world. Tasks have included supporting Air Combat Group training deployments to the United States, transporting Royal Australian Navy Sea Hawk helicopters and making fortnightly missions to the Middle East to supply Australian forces in Iraq and Afghanistan. The C-17s have also carried humanitarian supplies to Papua New Guinea during Operation Papua New Guinea Assist in 2007 and supplies and South African Puma helicopters to Burma in 2008 following Cyclone Nargis.cite journal|last=McLaughlin|first=Andrew|date=2008|title=Big Mover|journal=Australian Aviation|publisher=Phantom Media |location=Canberra|volume=September 2008|pages=p.45]

Canadian Forces

Canada has had a long-standing need for strategic airlift for humanitarian and military operations around the world. The Canadian Forces (CF) had followed a pattern similar to the Luftwaffe in using rented Antonovs and Ilyushins for many of their needs, including deploying the Disaster Assistance Response Team (DART) to tsunami-stricken Sri Lanka in 2005. The CF was forced to rely entirely on leased An-124 "Condors" for a deployment to Haiti in 2003, as well as a combination of leased "Condors", Ilyushins and USAF C-17s for moving heavy equipment into Afghanistan. The Canadian Forces Future Strategic Airlifter Project was initiated in 2002 to study various alternatives, including long-term leasing arrangements.

On July 5, 2006, the Canadian government issued a notice that it intended to negotiate directly with Boeing for the purchase of four airlifters.

On June 16, 2007, the first Canadian C-17 rolled off the assembly line at Long Beach, California and into the paint hangar for painting and addition of Canadian markings including the national logo and air force roundel. The first Canadian C-17 made its initial flight on July 23.

Future and potential operators

NATO

The Royal Danish Air Force signed a letter of intent to purchase C-17s on July 19, 2006 at the 2006 Farnborough Airshow to participate in the joint purchase and operation of C-17s within NATO, a program called the NATO Strategic Airlift Capability. [http://www.nato.int/issues/strategic-lift-air-sac/index.html NATO Strategic Airlift Capability] ] A further letter of intent was announced on September 12, 2006 that includes Bulgaria, the Czech Republic, Denmark, Estonia, Italy, Latvia, Lithuania, the Netherlands, Poland, Romania, the Slovak Republic, Slovenia and the United States to be part of a larger NATO joint purchase. [ [http://www.presstelegram.com/news/ci_4333961 NATO to place order for C-17s] ,Long Beach Press Telegram September 13,2006] This purchase would probably be similar to NATO's purchase of the E-3A Sentry. Later on, NATO countries Hungary and Norway, as well as Partner country Sweden also signed the Letter of Intent. Finland has also decided to join the program. [ [http://virtual.finland.fi/stt/showarticle.asp?intNWSAID=18332&group=Politics "Finland joins strategic airlifter procurement scheme"] , NewsRoom Finland, 25.3.2008.] The purchase is to be for two C-17s, which will operate in the same fashion as the NATO AWACS aircraft. [ [http://www.e3a.nato.int/ NATO AWACS] Homepage of the E-3 Component] ] The AWACS aircraft are jointly manned by crew from various NATO countries.

On May 9, 2008, a Foreign Military Sale Notice was posted at the Defense Security Cooperation Agency notifying the US Congress of a possible sale of two C-17s and related equipment worth up to US$700 million.cite news | first= | last= | coauthors= | title=FMS - Strategic Airlift Capability - C-17 GLOBEMASTER III Aircraft | date=2008-05-09 | publisher=Defense Security Cooperation Agency | url =http://www.dsca.osd.mil/PressReleases/36-b/2008/NATO_08-32.pdf | accessdate = 2008-05-09 ] The sale is expected to be completed in June 2008.Hoyle, Craig.

To support the two NATO C-17s in the Heavy Airlift Wing to be based at Pápa Air Base in Hungary the United States Air Force will provide an additional aircraft for use by the wing.

German Luftwaffe

The 2004 Indian Ocean earthquake and resultant tsunamis placed a strain on the global strategic airlifter pool. The performance of the C-17 in USAF and RAF service has led to Germany considering 2-4 C-17s for the "Luftwaffe" in a Dry lease arrangement, at least until the A400M is available in 2009. Germany's former Foreign Minister Joschka Fischer stated in the German news magazine "Der Spiegel" that the government needed its own organic strategic transport capability to be able to respond to disasters in a better manner than it was able to for this incident. During the tsunami relief effort, Germany tried to acquire transport through its usual method of wet leasing Antonov airlifters via private companies, but found to its dismay that there were no available aircraft. While the stated goal of a C-17 lease would be to last until the A400M's arrival, the "Luftwaffe" may elect to retain them." [http://www.expatica.com/source/site_article.asp?subchannel_id=52&story_id=15827&name=Berlin+to+designate+tsunami+relief+as+development+aid+ Berlin designates tsunami relief as aid] ." "Expatica". January 17, 2005.] The Luftwaffe acquired meanwhile airlift capacity through the NATO SALIS contract.

wedish Armed Forces

The Swedish Armed Forces have in a spring 2006 budget proposal identified a need for a strategic airlift capability for use with the EU Nordic Battle Group led by Sweden. Repeated reports in the Swedish media suggest that the Armed Forces are lobbying hard for the airlift requirement to be satisfied with the purchase of two C-17s. A request for information on the [http://www.fmv.se/ Swedish Defense Materiel Administration website] stated that Sweden must be able to deploy the battle group up to convert|4000|nmi|km away with 6000 tons of military equipment, quarter of that being oversized. In late 2006, Sweden signed a Letter of Intent (LOI) to join the NATO Strategic Airlift Capability (NSAC).

Others

In September 2006, General Paul V. Hester, USAF, commander of the United States Pacific Air Forces, stated that Japan was considering purchasing C-17s to equip the Japan Air Self-Defense Force. [ [http://www.airforcetimes.com/story.php?f=1-292925-2309942.php "Aussies learn C-17 ropes"] . "Air Force Times". October 25, 2006.]

Qatar has signed a deal for two C-17ERs for delivery in 2009. [http://www.boeing.com/news/releases/2008/q3/080721a_nr.html "Boeing, Qatar Announce C-17 Globemaster III Order"] , Boeing, 21 July 2008.]

Commercial interest

In the mid-1990s, McDonnell Douglas began to market the C-17 to commercial civilian operators, under the name MD-17. [ [http://www.boeing.com/news/releases/1997/news_release_970828n.html MD-17 Receives FAA Certification] ] Due to its high projected fuel, maintenance and depreciation cost for a low-cycle military design in commercial service, as well as a limited market dominated by the An-124 and A300-600ST, very little interest was expressed. After McDonnell Douglas merged with Boeing, the program was renamed BC-17. [ [http://www.boeing.com/news/releases/2000/news_release_000928a.html Boeing proposes BC-17X] ] However, the aircraft received no orders.

In March 2007, Global Heavylift Holdings LLC expressed interest in the purchase of up to thirty new airframes. [ [http://www.bloomberg.com/apps/news?pid=20601103&sid=aLruD6.HPifA&refer=us Bloomberg.com: Global Heavylift Plans to Buy C-17 Cargo Planes From Boeing] ] Another press release by Global Heavylift Holdings a few days later was a little more tame as to their financial backing.
