   The Lockheed Martin C-5M Super Galaxy is an upgraded version of the older C-5A, C-5B and C-5C military transport aircraft. A total of 131 C-5 series aircraft were delivered until 1989. These transport aircraft suffered from serious reliability problems that resulted in low mission capable rates. Availability was rearly above 50%. Furthermore with the retirement of the Lockheed C141 StarLifter the US Air Force (USAF) faced the shortfall in airlift capacity. Major upgrades were required to keep the C-5 fleet operational. The first aircraft was upgraded to the C-5M standard in 2006 and its test flights began during the same year. A modernization order for 52 C-5 aircraft was issued and low-rate production commenced in 2009. The Super Galaxy reached initial operating capability in 2014 with 16 aircraft delivered. By 2015 a total of 30 aircraft were upgraded. Deliveries were scheduled to be completed in 2018. It was planned that by 2017-2018 the US Air Force will reduce its C-5 fleet to 52 Super Galaxy aircraft, while non-upgraded C-5As, C-5Bs and C-5Cs will be retired. It is planned that the C-5M Super Galaxy will remain operational until 2030.

   The C-5M is the largest aircraft routinely operated by the US forces. Actually it is one of the largest military transport aircraft in the world. Only Antonov An-124 and one-off An-225 are bigger. Furthermore the C-5M Super Galaxy is the only true strategic airlifter of the USAF, capable of linking America directly to all theaters of combat without refueling. On longer missions the smaller C17 Globemaster III transport aircraft has to be refueled weather in flight or on friendly air bases. The Super Galaxy is mainly used for long-range logistical operations.

   On 13th September 2009 the C-5M aircraft set 41 new world records.

   Upgrades of the C-5M includes new General Electric F138-GE-100 (CF6-80C2L1F) commercial engines, upgraded avionics, new autopilot system, upgrades to landing gear, and other improvements. The previous C-5A/B Galaxy aircraft have suffered from serious reliability problems that resulted in low mission capable rates. The C-5M upgrade addressed some of the issues. Failure rates and maintenance hours reportedly reduced by more than half. Engine reliability reportedly increased tenfold. Still though the C-5M Super Galaxy is much more troublesome and expensive to maintain than the smaller C17 Globemaster III.

   Due to new engines the Super Galaxy is faster and can carry more cargo. It has a maximum payload capacity of 130 t. The original production version, the C-5A Galaxy, could carry 118 t. Furthermore due to newer engines the Super Galaxy has a longer range, as well as 30% shorter take-off and 38% higher climb rate.

   The C-5M has cavernous interior. The cargo hull is 36.8 m long, 5.8 m, and 4.1 m wide. The Super Galaxy has a roll-on/roll-off capability with access to cargo at both ends of the aircraft. It can carry two M1A2 Abrams main battle tanks, 10 LAV-25 armored reconnaissance vehicles or 16 HMMWVs. Alternatively it can carry 36 standard 463L pallets, or a combination of vehicles and pallets. The C-5 can also carry a combat ready military unit. The upper deck accommodates 73 passengers. The lower deck can be configured for transportation of 270 troops. Although not usually assigned airdrop duties, it can also drop paratroops.

   The Super Galaxy aircraft has an impressive range. With 54 t of cargo it can travel more than 9 700 km. Furthermore this military transport can be refueled during flight. Interestingly this military transport carries a whooping 150 t of fuel.

   This military transport is operated by a crew of 7, including two pilots, two flight engineers, and three loadmasters.
