UH-60 Black Hawk




Overview:

The UH-60 Black Hawk is a four-bladed, twin-engine, medium-lift utility helicopter manufactured by Sikorsky Aircraft. Sikorsky submitted the S-70 design for the United States Army's Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The Army designated the prototype as the YUH-60A and selected the Black Hawk as the winner of the program in 1976, after a fly-off competition with the Boeing Vertol YUH-61. The UH-60A entered service with the Army in 1979, to replace the UH-1 Iroquois as the Army's tactical transport helicopter. In the late 1960s, the United States Army began forming requirements in for its Utility Tactical Transport Aircraft System (UTTAS) helicopter to replace the UH-1 Iroquois based on experience in Vietnam. The Army also initiated the development of a new turbine engine for its helicopters that would become the General Electric T700. The Army required significant performance, survivability and reliability improvements from both UTTAS aircraft and powerplant. The Army released its UTTAS requests for proposals (RFP) in January 1972. Four prototypes were constructed, the first (YUH-60A) flying in October 1974, and evaluated against a rival Boeing-Vertol design, the YUH-61A. Prior to delivery of the prototypes to the US Army, a preliminary evaluation was conducted in November 1975 to ensure the aircraft could be operated safely during all testing. Three of the prototypes were delivered to the Army in March 1976, and one was kept by Sikorsky for internal research. The Black Hawk was selected for production in December 1976. Deliveries of the UH-60A to the US Army began in October 1978 and the helicopter entered service in June 1979. In 1987, the improved UH-60L was ordered. It featured more power and lift with the upgraded T700-701C engine and gearbox developed for the SH-60B Seahawk. Production on the L-model began in 1989. UH-60 Black Hawks equipped with M60 machine guns near An Najaf, Iraq in May 2005. In 2001, development of the next improved variant was approved. The UH-60M uses the more powerful T700-701D engine model and improved rotor blades. Manufacturing began on the UH-60M in 2006. The UH-60M will extend the service life of the UH-60 design well into the 2020s, features state of the art electronic instrumentation, flight controls and aircraft navigation control. The Black Hawk helicopter series can perform a wide array of missions, including the tactical transport of troops, electronic warfare, and aeromedical evacuation. A VIP version known as the VH-60N is used to transport important government officials (e.g., Congress, Executive departments) with the helicopter's call sign of "Marine One" when transporting the President of the United States. In air assault operations it can move a squad of 11 combat troops with equipment or reposition the 105 mm M102 howitzer with thirty rounds of 105 mm ammunition, and a four-man crew in a single lift. Alternatively, it can carry 2,600 lb (1,170 kg) of cargo or sling load 9,000 lb (4,050 kg) of cargo (for UH-60L/M). The Black Hawk is equipped with advanced avionics and electronics for increased survivability and capability, such as the Global Positioning System. The UH-60 can be equipped with stub wings at top of fuselage to carry fuel tanks or possibly armament. The initial stub wing system is called external stores support system (ESSS). It has two pylons on each wing to carry two 230 US gal (870 L) and two 450 US gal (1,700 L) tanks in total. The four fuel tanks and associated lines and valves form the external extended range fuel system (ERFS). The ESSS can also carry 10,000 lb (4,500 kg) of armament such as rockets, missile and gun pods. The ESSS entered service in 1986. However it was found that with four fuel tanks it would obstruct the firing field of the door guns. To alleviate the issue, the external tank system (ETS) with unswept stub wings to carry two fuel tanks was developed. The unit cost varies with the version due to the varying specifications, equipment and quantities. For example, the unit cost of the Army's UH-60L Black Hawk is $5.9 million while the unit cost of the Air Force MH-60G Pave Hawk is $10.2 million.

UH-1 Iroquois (Huey)




Overview:

The Bell UH-1 Iroquois is a multipurpose military helicopter, famous for its use in the Vietnam War. It is commonly known as (or officially in the U.S. Marine Corps) the "Huey". The UH-1 was developed by Bell Helicopter from 1955 US Army trials with the Bell Model 204. The initial designation of HU-1 (helicopter utility) led to its nickname, Huey. The aircraft was first used by the military in 1959 and went into tri-service production in 1962 as the UH-1. The last were produced in 1976 with more than 16,000 made in total, of which about 7,000 saw use during the Vietnam War. The UH-1 is a general utility helicopter. It has a metal fuselage of semi-monocoque construction with tubular landing skids and two rotor blades on the main rotor. Early UH-1 models featured a single Lycoming T53 turboshaft engine in versions with power ratings from 700 shp (522 kW) to 1,400 shp (1,040 kW). Later UH-1 and related models would feature twin engines and four-blade rotors. All aircraft in the UH-1 family have similar construction. The most-produced version, the UH-1H, is representative of all types, particularly the long-body versions. The main structure consists of two longitudinal main beams that run under the passenger cabin to the nose and back to the tail boom attachment point. The main beams are separated by transverse bulkheads and provide the supporting structure for the cabin, landing gear, under-floor fuel tanks, the transmission, engine and tail boom. The main beams are joined at the lift beam, a short aluminum girder structure that is attached to the transmission via a lift link on the top and the cargo hook on the bottom and is located at the aircraft's centre of gravity. The lift beams were changed to steel later in the UH-1H's life, due to cracking on high-time airframes. Both the fuselage and the tail boom are of a semi-monocoque design. The tail boom attaches to the fuselage with four bolts. The UH-1H's dynamic components include the engine, transmission, rotor mast, main rotor blades, tail rotor driveshaft, 42 degree and 90 degree gearboxes. The transmission is of a planetary type and reduces the T53-L13B engine's output to 324 rpm at the main rotor. The two-bladed, semi-rigid rotor design, with pre-coned and under-slung blades, is a development of early Bell model designs, such as the Bell 47 with which it shares common design features, including a dampened stabilizer bar. The two-bladed system reduces storage space required for the aircraft, but at a cost of higher vibration levels. The two-bladed design also is responsible for the characteristic 'Huey thump' when the aircraft is in flight, which is particularly evident during descent and in turning flight. The tail rotor is driven from the main transmission, via the two directional gearboxes which provide a tail rotor speed approximately six times that of the main rotor to increase tail rotor effectiveness. The UH-1H also features a synchronised elevator on the tail boom, which is linked to the cyclic control and allows a wider centre of gravity range. The standard fuel system consists of five interconnected fuel tanks, three of which are mounted behind the transmission and two of which are under the cabin floor. The landing gear consists of two arched cross tubes joining the skid tubes. The skids have replaceable sacrificial skid shoes to prevent wear of the skid tubes themselves. Skis and inflatable floats may be fitted. Internal seating is made up of two pilot seats and seating for up to 13 passengers or crew in the cabin. The maximum seating arrangement consists of a four man bench seat facing rearwards behind the pilot seats facing a five man bench seat in front of the transmission structure. Beside the transmission structure on either side of the aircraft are two two-man bench seats, facing outwards. All passenger seats are aluminium tube with canvas seat material and are quickly removable and reconfigurable. The UH-1H is rarely capable of lifting 15 people, except at very low density altitudes, fuels loads, and hovering heights and so fewer seats are usually fitted. The cabin may also be configured for up to six stretchers, an internal rescue hoist, auxiliary fuel tanks, spotlights or many other mission kits. Access to the cabin is via two aft-sliding doors and two small forward hinged panels. The doors and hinged panels may be removed for flight or the doors may be pinned open. Pilot access is via individual hinged doors. While the five main fuel tanks are self-sealing, the UH-1H was not equipped with factory armour, although armoured pilot seats were available. The UH-1H's dual controls are conventional for a helicopter and consist of a single hydraulic system boosting the cyclic stick, collective lever and anti-torque pedals. The collective levers have integral throttles, although these are not used to control rotor rpm, which is automatically governed, but are used for starting and shutting down the engine. The cyclic and collective control the main rotor pitch through torque tube linkages to the swash plate, while the anti-torque pedals change the pitch of the tail rotor via a tensioned cable arrangement. Some UH-1Hs have been modified to replace the tail rotor control cables with torque tubes similar to the UH-1N Twin Huey.

Sukhoi Su-33




Overview:

The Sukhoi Su-33 (NATO reporting name "Flanker-D") is a carrier-based multi-role fighter aircraft produced by Russian firm Sukhoi beginning in 1982. It is a derivative of the Su-27 ‘Flanker’ and was initially known as the Su-27K. The main differences from the Su-27 are that the Su-33 can operate from aircraft carriers and is capable of aerial refueling. Full scale design development of the Su-33 started in 1984 as T10K, under Konstantin Marbashev. N.F. Sadovnikov was appointed the Design Bureau's chief test pilot for the programme. Conceptual design had passed critical design review by November 1984, with the detailed design finalized in 1985. The Su-33 first flew in May 1985, and entered service in the Russian Navy in 1994. An air regiment comprising 24 fighters of the type was formed upon the Russian Navy’s only operating aircraft carrier, Admiral Kuznetsov. Unlike comparable American carrier-borne fighters like the F-14 Tomcat, the Su-33 uses a ski-jump instead of catapult for carrier takeoff. This method avoids the massive stresses produced by the catapult method, and provides the aircraft with a positive pitch and climb angle upon launch. However, when using a ski-jump, the Su-33 cannot launch at maximum takeoff weight. The Su-33 sports canards that shorten the take-off distance and improve maneuverability, but required reshaping of the leading edge extensions. The canards counter pitch-down force generated by leading and trailing edge flaps reducing approach speed by 1.5 times; they also act as destabilizers in supersonic flight, by reducing pitch trim drag. The wing area was also increased, though the span remained unchanged. The wings were fitted with power-assisted folding, and the vertical tails were shortened to allow the fighter to fit in the typically crowded hangars of an aircraft carrier. The rear radome was shortened and reshaped to allow for the tail hook, as well as to save space inside the hangars. The IRST was moved to provide better downward visibility and an L-shaped retractable refuelling probe was fitted to increase range. The Su-33 carries guided missiles such as the Kh-25MP, Kh-31 and Kh-41. The plane can be used in both night and day operations at sea. It can operate under assistance of the command center ship, or in conjunction with a Kamov Ka-31 (a variant of the Ka-27) early-warning helicopter. The R-27EM missiles provide it the capability to intercept antiship missiles. Other than air defence, the duties of the Su-33 include destruction of enemy ASW, AWACS, and transport aircraft, anti-shipping strike, support of amphibious landing, escort, reconnaissance, and laying of minefields. The state-run company Rosoboronexport is finishing negotiations with the People’s Republic of China to ship up to 50 aircraft totalling US$2.5 billion. China would initially acquire 2 aircraft worth US$100 million for testing and then have further options to acquire an additional 12-48 aircraft. The fighters are intended to be used with the fledgling Chinese aircraft carrier program. At the sixth Zhuhai Airshow in fall 2006, the first deputy director of the Military Technological Cooperation Bureau of Russian Federation, lieutenant general Aleksander Denisov of the Russian Air Force, publicly confirmed at the news conference that China had approached Russia for the possible purchase of Su-33, and negotiation was to start in 2007. The Xinhua News Agency subsequently published the information on its military website the same day (November 1, 2006) that China planned to "introduce Su-33". On 10 March 2009, the Moskovsky Komsomolets newspaper reported that the talks to sell the aircraft to China had failed over fears that China would make a copy for export. China had previously obtained a manufacturing license for Su-27 production. An unnamed Russian official told UPI that the Chinese order for only seven aircraft was far too small to justify restarting the production line. Sukhoi is working on a more advanced version, the Su-33K, though technical details need to be worked out to integrate the advanced technologies of the Su-35 fighters into the Su-33 airframe.

OH-58D Kiowa







Overview:

OH-58 Kiowa is a family of single-engine, single-rotor, military helicopters used for observation, utility, and direct fire support. Bell Helicopter originally manufactured the OH-58 for the United States Army, based on the 206A JetRanger helicopter. The Kiowa has been in continuous use by the U.S. Army since 1969. The latest model, the OH-58D Kiowa Warrior, is primarily operated in an armed reconnaissance role in support of ground troops. The OH-58 has been exported to Austria, Canada, Dominican Republic, Taiwan, and Saudi Arabia; as well as having been produced under license in Australia. On 14 October 1960, the United States Navy solicited response from 25 aircraft manufacturers to a request for proposals (RFP) on behalf of the Army for the Light Observation Helicopter (LOH). Bell entered the competition along with 12 other manufacturers, including Hiller Aircraft and Hughes Tool Co., Aircraft Division. Bell submitted the D-250 design, which would be designated as the YHO-4. On 19 May 1961, Bell and Hiller were announced as winners of the design competition. The Army's decision to acquire the NTSH resulted in the "Army Helicopter Improvement Program (AHIP)". Both Bell Helicopter and Hughes Helicopters redesigned their scout aircraft to compete for the contract. Bell offered a more robust version of the OH-58 in their model 406 aircraft, and Hughes offered an upgraded version of the OH-6, and on 21 September 1981, Bell Helicopter Textron was awarded a development contract. The first prototype flew on 6 October 1983, and the aircraft entered service in 1985 as the OH-58D. Initially intended to be used in attack, cavalry and artillery roles, the Army only approved a low initial production level and confined the role of the OH-58D to field artillery observation. The Army also directed that a follow-on test be conducted to further evaluate the aircraft due to perceived deficiencies. On 1 April 1986, the Army formed a task force at Fort Rucker, Alabama, to remedy deficiencies in the AHIP. As a result of those deliberations, the Army had planned to discontinue the OH-58D in 1988 and focus on the LHX, but Congress approved $138 million for expanding the program, calling for the AHIP to operate with the Apache as a hunter/killer team; the AHIP would locate the targets, and the Apache would destroy them in a throwback to the traditional OH-58/AH-1 relationship. The Secretary of the Army directed instead that the aircraft's armament systems be upgraded, based on experience with Task Force 118's performance operating armed OH-58D helicopters in the Persian Gulf in support of Operation Prime Chance, and that the aircraft be used primarily for scouting and armed reconnaissance. The armed aircraft would be known as the OH-58D Kiowa Warrior, denoting its new armed configuration. Beginning with the production of the 202nd aircraft (s/n 89-0112) in May 1991, all remaining OH-58D aircraft were produced in the Kiowa Warrior configuration. In January 1992, Bell Helicopter received its first retrofit contract to convert all remaining OH-58D Kiowa helicopters to the Kiowa Warrior configuration.

MRAP






Overview:

Mine Resistant Ambush Protected (MRAP) vehicles are a family of armored fighting vehicles designed to survive IED attacks and ambushes. IEDs cause the majority (63%) of US deaths in Iraq. There is no common MRAP vehicle design; there are several vendors, each with a competing entry. Brig. General Michael Brogan of the United States Marine Corps is in charge of the MRAP program, for which the Marines are the lead service. The Marine Corps had planned to replace all HMMWVs in combat zones with MRAP vehicles, although this appears to have changed. As armored vehicles are considered an "urgent need" in Iraq and Afghanistan, this program is primarily funded under an "emergency war budget". On 2007-05-08 Secretary of Defense Robert Gates stated that the acquisition of MRAPs are the Department of Defense highest priority, so for fiscal year 2007 US$1.1 billion is earmarked for MRAP . Gates decided to ramp up MRAP orders after the Marines reported in 2004 that no troops had died in more than 300 IED attacks on Cougars As of May 6, 2008 eight soldiers had been reported killed in the thousands of MRAPs in Iraq, according to news service Knight Ridder. In June 2008, USA Today reported that roadside bomb attacks and fatalities were down almost 99% partially due to MRAPs. "They've taken hits, many, many hits that would have killed soldiers and Marines in uparmored Humvees," according to Adm. Michael Mullen, chairman of the Joint Chiefs of Staff. Maj. General Rick Lynch, who commanded a division in Baghdad, told USA Today the 14-ton MRAPs have forced insurgents to build bigger, more sophisticated bombs to knock out the vehicles. Those bombs take more time and resources to build and set up, which gives U.S. forces a better chance of catching the insurgents in the act and then attacking them. Several criticisms of the MRAP program have been its lack of a common design, which presents a wartime logistical challenge, and the relatively few number of units which have been delivered to Iraq and Afghanistan, despite large orders. However, some analysts see the diversity of MRAP vehicles as an advantage. Other criticisms include the vehicle's weight and size, which severely limit its mobility off main roads, in urban areas, and over bridges. 72 percent of the world's bridges cannot hold the MRAP. Its heft also restricts several of the vehicles from being transported by C-130 cargo aircraft or the amphibious ships that carry Marine equipment and supplies. Although three MRAP vehicles will fit in a C-17 aircraft, airlifting is extremely expensive at $750,000 per vehicle, estimated by the U.S. Transportation Command. In an effort to rush more vehicles to the theatre, the US Air Force even contracted several Russian Antonov An-124 heavy cargo aircraft, which became a familiar sight in the skies above cities such as Charleston, SC where some MRAPs are produced. For comparison, sealifting costs around $13,000 per vehicle, but takes between three and four weeks for the vehicle to arrive in theater. For these reasons, in December 2007, the Marine Corps reduced its request from 3700 vehicles to 2300. The Army is also reassessing its MRAP requirements in Iraq although there is no sign that they intend to reduce the number of vehicles it intends to procure. Additional vehicles may be sent to Afghanistan where commanders are requesting them. This program is very similar to the US Army's Medium Mine Protected Vehicle program. MRAP vehicles usually have "V" shaped hulls to deflect away any explosive forces originating below the vehicle, thereby protecting the vehicle and its passenger compartment. Typically these explosions are from land mines, but they can also be IEDs. This design dates to the 1970s when it was first introduced in 1978 with the South African Buffel (Buffalo) armored personnel carrier (APC), another South African APC the Casspir was the inspiration and prototype for the US Marines MRAP project. Derivatives of these vehicles have since been used by various military forces around the world. Multiple contracts have been placed by the United States for this type of vehicle in response to the situation in the Iraq War. By issuing contracts to several companies, the Marine Corps hopes to accelerate the rate of production, in order to expedite the delivery of vehicles to deployed forces. However, there are only two steel mills in the United States, Oregon Steel Mills, Inc. and International Steel Group, qualified to produce armored steel for the Defense Department, which has been in negotiations to ensure enough steel is available to keep pace with production. The concept is to replace HMMWV type vehicles with a more robust, survivable vehicle when on patrol "outside the wire."

MQ-9 Reaper (Predator B)






Overview:

The MQ-9 Reaper (originally the Predator B) is an unmanned aerial vehicle (UAV) developed by General Atomics Aeronautical Systems (GA-ASI) for use by the United States Air Force, the United States Navy, and the British Royal Air Force. The MQ-9 is the first hunter-killer UAV designed for long-endurance, high-altitude surveillance. The MQ-9 is a larger and more capable aircraft than the earlier MQ-1 Predator. It can use MQ-1's ground systems. The MQ-9 has a 950-shaft-horsepower turboprop engine, far more powerful than the Predator's 115 hp (86 kW) piston engine. The increase in power allows the Reaper to carry 15 times more ordnance and cruise at three times the speed of the MQ-1. In 2008 the New York Air National Guard 174th Fighter Wing began to transition from F-16 piloted planes to MQ-9 Reaper drones, which are capable of remote controlled or autonomous flight, becoming the first all-robot attack squadron. Then U.S. Air Force Chief of Staff General T. Michael Moseley said, "We've moved from using UAVs primarily in intelligence, surveillance, and reconnaissance roles before Operation Iraqi Freedom, to a true hunter-killer role with the Reaper." As of 2009 the U.S. Air Force’s fleet stands at 195 Predators and 28 Reapers. With the success of the MQ-1 in combat, General Atomics anticipated the Air Force's desire for an upgraded aircraft and, using its own funds, set about redesigning Predator. General Atomics began development of the Reaper with the "Predator B-001", a proof-of-concept aircraft, which first flew on 2 February 2001. The B-001 was powered by a Garrett AiResearch TPE-331-10T turboprop engine with 950 shp (712 kW). It had a standard Predator airframe, except that the wings were stretched from 48 feet (14.6 m) to 66 feet (20 m). The B-001 had a speed of 220 kts (390 km/h) and could carry a payload of 750 pounds (340 kilograms) to an altitude of 50,000 feet (15.2 kilometers) with an endurance of 30 hours. GA refined the design, taking it in two separate directions. The first was with a jet-powered version. The "Predator B-002" was fitted with a Williams FJ44-2A turbofan engine with 10.2 kN (2,300 lbf, 1,040 kgf) thrust. It had payload capacity of 475 pounds (215 kilograms), a ceiling of 60,000 feet (18.3 kilometers) and endurance of 12 hours. The U.S. Air Force has ordered two airframes for evaluation, delivered in 2007. The second was the "Predator B-003", referred to by GA as the "Altair", which has a new airframe with an 84-feet (25.6 m) wingspan and a takeoff weight of about 7,000 pounds (3,175 kilograms). Like the Predator B-001, it is powered by a TP-331-10T turboprop. This variant has a payload capacity of 3,000 pounds (1,360 kilograms), a maximum ceiling of 52,000 feet (15.8 kilometers), and an endurance of 36 hours.

Mikoyan MiG-29





Overview:

The Mikoyan MiG-29 (Russian: Микоян МиГ-29) is a 4th generation jet fighter aircraft designed in the Soviet Union for an air superiority role. Developed in the 1970s by the Mikoyan design bureau, it entered service with the Soviet Air Force in 1983, and remains in use by the Russian Air Force as well as in many other nations. NATO’s reporting name for the MiG-29 is "Fulcrum", which was unofficially used by Soviet pilots in service. The MiG-29 along with the Su-27 were developed to counter new American fighters such as the F-15 Eagle, and the F-16 Fighting Falcon. Because it was developed from the same basic parameters laid out by TsAGI for the original PFI, the MiG-29 is aerodynamically broadly similar to the Sukhoi Su-27, but with some notable differences. It is built largely out of aluminium with some composite materials. It has a mid-mounted swept wing with blended leading-edge root extensions (LERXs) swept at around 40°. There are swept tailplanes and two vertical fins, mounted on booms outboard of the engines. Automatic slats are mounted on the leading edges of the wings; they are four-segment on early models and five-segment on some later variants. On the trailing edge, there are maneuvering flaps and wingtip ailerons. At the time of its deployment, it was the first Soviet and perhaps world's first jet fighter in service capable of executing the Pugachev Cobra maneuver. The MiG-29 has hydraulic controls and a SAU-451 three-axis autopilot but, unlike the Su-27, no fly-by-wire control system. Nonetheless, it is very agile, with excellent instantaneous and sustained turn performance, high alpha capability, and a general resistance to spins. The airframe is stressed for 9-g (88 m/s²) maneuvers. The controls have "soft" limiters to prevent the pilot from exceeding the g and alpha limits, but these can be disabled manually. In joint USAF-Luftwaffe exercises, the MiG-29 that the Luftwaffe fielded defeated the F-16 in close combat almost every time using its highly practical IRST sensor and helmet mounted display, together with the Vympel R-73 (NATO: AA-11 'Archer') missile. The MiG-29 has two widely spaced Klimov RD-33 turbofan engines, each rated at 50.0 kN (11,240 lb) dry and 81.3 kN (18,277 lb) in afterburner. The space between the engines generates lift, thereby reducing effective wing loading, to improve maneuverability. The engines are fed through wedge-type intakes fitted under the LERXs, which have variable ramps to allow high-Mach speeds. As an adaptation to rough-field operations, the main air inlet can be closed completely and alter using the auxiliary air inlet on the upper fuselage for takeoff, landing and low-altitude flying, preventing ingestion of ground debris (foreign object damage [FOD]). Thereby the engines receive air through louvers on the LERXs which open automatically when intakes are closed. However the latest variant of the family, the MiG-35, eliminated these dorsal louvers, and adopted the mesh screens design in the main intakes, similar to those fitted to the Su-27. The internal fuel capacity of the original MiG-29B is only 4,365 liters distributed between six fuel tanks, four in the fuselage and one in each wing. As a result, the aircraft has a very limited range, in line with the original Soviet requirements for a point-defense fighter. For longer flights, this can be supplemented by a 1,500 liter (330 Imp gal, 395 USgal) centerline drop tank and, on later production batches, two 1,150 liter (365 Imp gal, 300 USgal) underwing drop tanks. In addition, a small number have been fitted with port-side inflight refueling probes, allowing much longer flight times by using a probe-and-drogue system. Some MiG-29B airframes have been upgraded to the "Fatback" configuration (MiG-29 9-13), which adds a dorsal-mounted internal fuel tank. Advanced variants, such as the MiG-35, can be fitted with a conformal fuel tank on the dorsal spine, although none of them have yet entered service. Armament for the MiG-29 includes a single GSh-30-1 30 mm cannon in the port wing root. This originally had a 150-round magazine, which was reduced to 100 rounds in later variants. Original production MiG-29B aircraft cannot fire the cannon when carrying a centerline fuel tank as it blocks the shell ejection port. This issue was corrected in the MiG-29S and later versions. Three pylons are provided under each wing (four in some variants), for a total of six (or eight). The inboard pylons can carry either a 1,150 liter (300 US gallon) fuel tank, one Vympel R-27 (AA-10 "Alamo") medium-range air-to-air missile, or unguided bombs or rockets. Some Soviet aircraft could carry a single nuclear bomb on the port inboard station. The outer pylons usually carry R-73 (AA-11 "Archer") dogfight missiles, although some users still retain the older R-60 (AA-8 "Aphid"). A single 1,500 liter (400 US gallon) tank can be fitted to the centerline, between the engines, for ferry flights, but this position is not used for combat stores. The original MiG-29B can carry general-purpose bombs and unguided rocket pods, but not precision-guided munitions. Upgraded models have provision for laser-guided and electro-optical bombs, as well as air-to-surface missiles.
