C-17 Globemaster III Tactical Transport Aircraft

The Boeing C-17 Globemaster III military airlift aircraft is a high-wing, four-engine, T-tailed military transport vehicle capable of carrying payloads up to 169,000lb (76,657kg).

It has an international range and the ability to land on small airfields. A fully integrated electronic cockpit and advanced cargo system allows a crew of three (the pilot, co-pilot and loadmaster) to operate all systems on any type of mission.

In February 2009, a $2.95bn contract was awarded to Boeing to deliver 15 additional C-17s for the US Air Force. Two C-17s were delivered to the Stewart Air National Guard Base in July 2011.

Since it entered service in January 1995, 218 aircraft have been delivered to the US Air Force.

C-17 design features


“Since it entered service in January 1995, 218 aircraft have been delivered to the US Air Force.”

A propulsive lift system allows the C-17 to achieve safe landings on short runways. The C-17 is capable of landing a full payload in less than 3,000ft. The propulsive lift system uses engine exhaust to generate lift.

The engine exhaust is directed onto large flaps, which extend into the exhaust stream, allowing the aircraft to fly a steep approach at a relatively low landing speed.


A Honeywell auxiliary power unit (APU) turbine is fitted in the front of the right main landing gear sponson to provide engine starting and ground power; a “ram air turbine” will be extended from the right sponson in the case of a comprehensive power failure, to provide hydraulic system power for minimal flight control. There are six fuel tanks in the wings, with a total capacity of 102,614 liters (27,108 US gallons), and an inflight refueling socket behind the cockpit. An inert-gas generation system helps reduce fuel system fires or explosions. In later production, at least some C-17s were fitted with a wing center-section tank with a capacity of 36,340 liters (9,600 US gallons) of fuel, these aircraft being informally designated as “C-17 ER”. It is unclear if the entire fleet has been kitted up to ER specification.

The nose landing gear has two wheels, while each of the two main gear assemblies has six wheels in two rows of three. The nose gear retracts forward and is steerable by rudder pedals, as well as a tiller for tight ground maneuvering. The main gear extends straight down from its sponsons; all landing gear assemblies will open by gravity in case of system failure. The landing gear can support steep-angle combat zone landings.

The aircraft is capable of turning in a small radius and can complete a 180° star turn in 80ft. The aircraft can also carry out routine backing. A fully loaded aircraft is capable of backing up a 2% gradient slope using the directed flow thrust reversers.

The C-17 cockpit accommodates pilot, co-pilot and two observer positions. The digital avionics system has four Honeywell multifunction cathode-ray tube displays, two full-capability HUDs (head-up displays) plus cargo systems.


The quadruple-redundant electronic flight control system also has a mechanically-actuated backup system.

APS-150/RDR-4000M Weather Radar


The Honeywell RDR-4000 is an advanced weather hazard and avoidance radar for both commercial and large military aircraft. Also known as IntuVue (for intuitive view), it is certified by the U.S. FAA for commercial use. The RDR-4000 collects a complete 3-D volumetric scan of the weather and terrain ahead of the aircraft, always showing the most reflective part of storm cells. The radar contains an internal worldwide terrain database, enabling it to extract ground clutter without the significant losses associated with ground suppression techniques. The data in the buffer continuously updates and compensates for aircraft movement.


The military version of the RDR-4000 radar is called the RDR-4000M, or APS-150. In addition to the weather, windshear, and turbulence detection features, the military radar provides a high-resolution ground map mode, a “skin paint” mode to better detect the returns from the skin of other aircraft, and a master cut-off switch for silent operations. The APS-150 equips USAF C-17 Globemasters, and sales will continue to support this platform. Another APS-150 platform is the Kawasaki C-2 tactical transport; Japan is looking to purchase 40-60 aircraft. In addition, EADS has chosen the APS-150 to equip its multinational A400M military transport. The A400M should be a major boost to APS-150 production. Source @forecastinternational.com

“The C-17 is capable of landing a full payload in less than 3,000ft.”
For cargo operations the C-17 requires a crew of three: pilot, copilot, and loadmaster. The cargo compartment is 88 feet (27 m) long by 18 feet (5.5 m) wide by 12 feet 4 inches (3.76 m) high. The cargo floor has rollers for palletized cargo but it can be flipped to provide a flat floor suitable for vehicles and other rolling stock. Cargo is loaded through a large aft ramp that accommodates rolling stock, such as a 69-ton (63-metric ton) M1 Abrams main battle tank, other armored vehicles, trucks, and trailers, along with palletized cargo. Source @wikiwand.com

The cargo compartment has a sufficiently large cross-section to transport large wheeled and tracked vehicles, tanks, helicopters (such as the AH-64 Apache), artillery and weapons such as the Patriot missile system. Three Bradley armoured vehicles comprise one deployment load on the C-17. The US Army M1A1 main battle tank can be carried with other vehicles.

The maximum payload is 170,900lb (77,519kg) with 18 pallet positions, including four on the ramp. Airdrop capabilities include: a single load of up to 60,000lb (27,216kg), sequential loads of up to 110,000lb (49,895kg), Container Delivery System (CDS) airdrop up to 40 containers, 2,350lb (1,066kg) each, up to 102 paratroops.

Large Package Week, Joint Operational Access Exercise 13-01Image @defense.govc-17_paratroopers-2

The transport aircraft is equipped for LAPES (low-altitude parachute extraction system) drops. For Medevac, the C-17 can transport up to 36 litter and 54 ambulatory patients and attendants. C-17s can take off from a 7,600ft airfield, fly 2,400nm and refuel while in flight. It can land on a 3,500ft-long (1,064m) and 90ft-wide (27.4m) airstrip.


The aircraft is operated by a crew of three (pilot, co-pilot and loadmaster), reducing both manpower requirements and operating costs. This cost-effective flight crew complement is made possible through the use of an advanced digital avionics system and advanced cargo systems. In the cargo compartment, the C-17 carries the Army’s wheeled vehicles in two side-by-side rows. For example, three combat-ready Stryker vehicles or 10 HMMWV (Humvees) comprise one deployment load. Also, the C-17 is able to transport the M1 Abrams main battle tank. Furthermore, the C-17 can carry up to 102 troops, 36 litter patients, or 18 standard 463-L pallets. Cargo and vehicles are loaded onto the C-17 through a large aft door that accommodates military vehicles and palletized cargo. The C-17 can carry virtually all of the Army’s air-transportable equipment. Source @bga-aeroweb.com

Countermeasure technology

The AN/AAR-47 has a suite of surface-mounted thermal sensors around the aircraft, which detect the thermal signature of the missile exhaust plume. Frequency selection and signal processing techniques are used to minimise the false alarm rate.


AN/AAR-47 missile warning system

images (1)

The AN/AAR-47 Missile Warning System is a Missile Approach Warning system used on slow moving aircraft such as helicopters and military transport aircraft to notify the pilot of threats and to trigger the aircraft’s countermeasures systems. Its main users are the U.S Army, Navy and Air Force, but is also operated by other countries. Originally developed by Loral (now part of BAE Systems), it has been solely a product of Alliant Techsystems(ATK) since 2002.

Method of Operation

The AN/AAR-47 passively detects missiles by their Ultraviolet signature, and uses algorithms to differentiate between incoming missiles and false alarms. Newer versions also have laser warning sensors and are capable of detecting a wider range of threats. After processing the nature of the threat, the system gives the pilot an audio and visual warning, and indicates the direction of the incoming threat. It also sends a signal to the aircraft’s infrared countermeasures system, which can then for example deploy flares.



The AAR-47 missile warning system consists of 4 Optical Sensor Converters (OSC), a Computer Processor and a Control Indicator. The system is relatively light at a total weight of approximately 32 pounds.

There is one optical sensor converter for each side of the aircraft. They have an infrared camera for detecting incoming missiles. The Optical modules since version AAR-47(V)2 include a laser warning sensor, and versions since AAR-47A(V)2 further incorporate an ultraviolet sensor for improved dynamic blanking laser warning detection.

The computer processor evaluates the data from the OSC:s and analyzes whether a detected event is an incoming missile. If a threat is detected, it sends a signal to the control indicator which informs the crew, and the aircraft’s infrared countermeasures system.

Source @revolvy.com

The system provides a warning to the crew via the cockpit indicator unit of the presence and direction of the missile threat. A signal is automatically sent to the ALE-47 dispenser.

The AN/ALE-47 is capable of carrying a mix of expendable countermeasures, including jammers. The system interfaces to the C-17 aircraft’s sensors. The aircrew can select the mode of operation of the dispenser for fully automatic, semi-automatic or manual operation.

AN/ALE-47 countermeasures system

AN/ALE-47 dispenser and associated equipment

In response to automated warnings of radar, infrared, laser and other threats against aircraft, theAN/ALE-47 Countermeasures Dispenser System (CMDS) both assists the crew in staying aware of the threats, and managing the deployment of electronic warfare devices that operate externally to the vehicle. “Electronic”, in this context, covers enemy sensors across the electromagnetic spectrum. Electronic defense includes, as well as receivers and computers that detect and analyze threats, both countermeasures that are part of the aircraft, but also expendables that are released from it.

In other words, it both acts as an electronics countermeasures suite controller and as an electronic warfare expendables dispenser. It replaces the AN/ALE-39. Alternatively, it can be controlled by other control systems, such as the AN/ALQ-213

The cockpit control unit can be used to input mission data, together with the numbers and types of expendable countermeasures systems loaded into the ALE-47. The cockpit controller updates and displays the status of the dispenser and the numbers and types of countermeasures remaining.

The ALE-47 is capable of dispensing the new-generation active expendable decoys, POET and GEN-X, in addition to the conventional chaff and flare decoys that are compatible with the previous-generation ALE-40 and ALE-39 dispensers.

A total of 56 USAF C-17 aircraft are equipped with the Northrop Grumman large aircraft infra-red countermeasures (LAIRCM) system.

AN/AAQ-24(V) Nemesis

The AN/AAQ-24(V) Directional Infrared Countermeasure (DIRCM) system is the only DIRCM system in production today that will protect aircraft from today’s infrared guided missiles.


Traditional IR countermeasures are not effective against the modern IR missiles that are growing in popularity among terrorist groups and in thirdworld countries. A Directional Infrared Countermeasures (DIRCM) system is required to defeat the latest and future advanced IR threats, and has a lower life cycle cost compared to other IR countermeasure approaches.

  • Simultaneously tracks and defeats threats in clutter environments
  • Fast, accurate threat detection and simultaneous jamming in all current IR threat Bands (I, II and IV)
  • Counters all fielded IR missile threats using a single generic jam waveform
  • Complete end-to-end self-testing features reduce life-cycle maintenance
  • Compatible with existing support facilities

Customized installation

The AAQ-24(V) is available in a laser-based configuration. Northrop Grumman then selects from a modular family of transmitters, jammers and missile warning systems to provide a customized installation best able to meet your specific platform, mission and budget requirements. Upgrades to existing systems are easy to install without further airframe modifications.

LAIRCM is based on the AN/AAQ-24(V) Nemesis. It entered low-rate initial production in August 2002 and completed initial operational test and evaluation in July 2004. 25 upgraded aircraft have been delivered. The system entered service in 2007. The four aircraft leased by the UK Royal Air Force (RAF) are fitted with LAIRCM.

Turbofan engines of the transport aircraft

indian_c-17-globemaster-iii-and-f117-engines_090712Image @xairforces.net173348_800Image @airteamimages.com

The four Pratt & Whitney PW2040 (military designation-F117-PW-100) turbofan engines with 40,440lb thrust each are integrated in the wings. Engine thrust reversers, which are operable in flight, and speed brakes enable the aircraft to carry out rapid deceleration and descent manoeuvres.

The C-17 is designed to operate from runways as short as 3,500 ft (1,100 m) and as narrow as 90 ft (27 m). In addition, the C-17 can operate from unpaved, unimproved runways (although with greater chance of damage to the aircraft). The thrust reversers can be used to move the aircraft backwards and reverse direction on narrow taxiways using a three- (or more) point turn. The plane is designed for 20 man-hours of maintenance per flight hour, and a 74% mission availability rate. Source @wikiwand.com
