Eurocopter Tiger

In 1984, the West German and French governments issued a requirement for an advanced multi-role battlefield helicopter. A joint venture consisting of MBB and Aérospatiale was subsequently chosen as the preferred supplier. Due to high costs, the program was cancelled in 1986, but was relaunched during 1987. Subsequently, in November 1989, Eurocopter received a contract to build five prototypes. Three were to be unarmed testbeds and the other two armed prototypes: one for the German anti-tank variant and the other for the French escort helicopter variant.
The first prototype first flew in April 1991. When Aerospatiale and MBB, among others, merged in 1992 to form the Eurocopter Group, the Tiger program was transferred as well. Serial production of the Tiger began in March 2002 and the first flight of the first production Tiger HAP for the French Army took place in March 2003. The delivery of the first of the eighty helicopters ordered by the French took place in September 2003.
At the end of 2003, deliveries began of the 80 UHT version combat support helicopters ordered by Germany to the Federal Office of Defense Technology and Procurement.
In December 2001, Eurocopter was awarded the contract for the Australian Army’s "Air 87 Requirement", which was for 22 helicopters of the Tiger ARH (Armed Reconnaissance Helicopter) version. The first Tiger ARH was scheduled to enter service in 2004. 18 of the 22 aircraft will be assembled at the Brisbane facility of Australian Aerospace, the local Eurocopter subsidiary in Australia.
In September 2003, Spain selected a variant of the Tiger HAP combat support helicopter - the Tiger HAD - for its army. The 24 helicopters of this type that have been ordered will be armed with the Trigat and Mistral missile systems. They will also have an uprated Enhanced MTR390 engine and a heavier payload. Deliveries are scheduled for 2007-2008.[1] France opted to upgrade most of its HAP Helicopter to HAD; so the HAC-Variant will never be built.
In June 2006, the Rafael Spike-ER was selected by the Spanish Army to be the ATGM of the Spanish HAD, instead of the previously announced Trigat missile system.
In July 2006, the Saudi Government signed a contract to purchase a total of 142 helicopters, including 12 Tiger attack helicopters. The deal later fell through, as Saudi Arabia demonstrated an interest in acquiring Russian helicopters instead.

AH-64 Apache

The AH-64 Apache is a four-blade, twin-engine attack helicopter with reverse-tricycle landing gear, and tandem cockpit for a crew of two. The Apache was developed as Model 77 by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the AH-1 Cobra. First flown on 1 October 1975, the AH-64 features a nose-mounted sensor suite for target acquisition and night vision systems. The Apache is armed with a 30 mm M230 Chain Gun carried between the main landing gear, under the aircraft's belly. The AH-64 also carries a mixture of AGM-114 Hellfire and Hydra 70 rocket pods on four hardpoints mounted on stub-wing pylons. The AH-64 also features double- and triple-redundant aircraft systems to improve survivability for the aircraft and crew in combat, as well as improved crash survivability for the pilots.
The Army selected the AH-64 over the Bell YAH-63 in 1976, awarding Hughes Helicopters a pre-production contract for two more aircraft. In 1982, the Army approved full production. McDonnell Douglas continued production and development, after purchasing Hughes Helicopters from Summa Corporation in 1984. On 15 April 1992, the first AH-64D Apache Longbow prototype was flown, and the first production aircraft was delivered to the Army in the spring of 1997. In August 1997, Boeing and McDonnell Douglas merged to become The Boeing Company. Today, AH-64 production is continued by the Boeing Integrated Defense Systems division.

Mil Mi-24

The Mil Mi-24 (Cyrillic Миль Ми-24, NATO reporting name "Hind") is a large helicopter gunship and low-capacity troop transport produced by Mil Moscow Helicopter Plant and operated from 1972 by the Soviet Air Force, its successors, and over thirty other nations. In October 2007, the Russian Air Force announced it would replace its 250 Mi-24 helicopter gunships with 300 more modern Mi-28s and possibly Ka-50s by 2015.^[1][2]

In NATO circles the export versions, Mi-25 and Mi-35, are simply denoted with a letter suffix as "Hind D" and "Hind E" respectively. Soviet pilots called the aircraft летающий танк (letayushchiy tank, “flying tank”). More common unofficial nicknames were Крокодил (Krokodil, “Crocodile”), due to the helicopter's new camouflage scheme ^[3] and Стакан (Stakan, “Glass”), because of the flat glass plates which surrounded the three place cockpit of the Mi-24.

During the early 1960s, it became apparent to Soviet designer Mikhail Leont'yevich Mil that the trend towards ever-increasing battlefield mobility would result in the creation of flying infantry fighting vehicles, which could be used to perform both fire support and infantry transport missions. The first expression of this concept was a mock-up unveiled in 1966 in the experimental shop of the Ministry of Aircraft's factory number 329 where Mil was head designer. The mock-up designated V-24 was based on another project, the V-22 utility helicopter, which itself never flew. The V-24 was similar in layout and configuration to the UH-1A Huey, with a central infantry compartment that could hold eight troops sitting back to back, and a set of small wings positioned to the top rear of the passenger cabin, capable of holding up to six missiles or rockets, with a twin-barreled GSh-23L cannon fixed to the landing skid.

AH-1 Cobra

The AH-1 Cobra (company designation: Bell 209) is a two-bladed, single engine attack helicopter manufactured by Bell. It shares a common engine, transmission and rotor system with the older UH-1 Iroquois. The AH-1 is also sometimes referred to as the HueyCobra or Snake.
The AH-1 was the backbone of the United States Army's attack helicopter fleet, but has been replaced by the AH-64 Apache in Army service. Upgraded versions continue to fly with several other users. The AH-1 twin engine versions remain in service with United States Marine Corps as the service's primary attack helicopter.
Closely related with the development of the Bell AH-1 is the story of the Bell UH-1 Iroquois — predecessor of the modern helicopter, icon of the Vietnam War and still one of the most numerous helicopter types in service today.
The UH-1 made the theory of air cavalry practical, as the new tactics called for US forces to be highly mobile across a wide area. Unlike before, they would not stand and fight long battles, and they would not stay and hold positions. Instead, the plan was that the troops carried by fleets of UH-1 Hueys would range across the country, to fight the enemy at times and places of their own choice.
It soon became clear that the unarmed troop helicopters were vulnerable against ground fire from Việt Cộng and North Vietnamese troops, particularly as they came down to drop their troops in a landing zone. Without friendly support from artillery or ground forces, the only way to pacify a landing zone was from the air, preferably with a machine that could closely escort the transport helicopters, and loiter over the landing zone as the battle progressed. By 1962 a small number of armed UH-1As were used as escorts, armed with multiple machine guns and rocket mounts.

Mil Mi-17

Developed from the basic Mi-8 airframe, the Mi-17 was fitted with the larger TV3-117MT engines, rotors, and transmission developed for the Mi-14, along with fuselage improvements for heavier loads. Optional engines for 'hot and high' conditions are the 1545kW (2070 shp) Isotov TV3-117VM. Recent exports to China and Venezuela for use in high mountains have the new VK-2500 version of the engine with FADEC control.
The designation Mi-17 is for export; Russian armed forces call it Mi-8MT. The Mi-17 can be recognized because it has the tail rotor on the port side instead of the starboard side, and dust shields in front of the engine intakes. Engine cowls are shorter than on the TV2 powered Mi-8, not extending as far over the cockpit, and an opening for bleed-valve outlet is present forward of the exhaust.
Actual model numbers vary by builder, engine type, and other options. As an example, the sixteen new Ulan Ude built machines delivered to the Czech Air Force in 2005 with –VM model engines were designated as Mi-171Sh, a development of the Mi-8AMTSh. Modifications include a new large door on the right side, improved Czech-built APU, Kevlar armor plates around the cockpit area and engines. Eight have a loading ramp in place of the usual clamshell doors, and will load a vehicle up to the size of an SUV.
The Mi-17 is also used for search and rescue teams like Malaysian Fire and Rescue Department in Malaysia.
In October 2007 defense-aerospace.com reported the government of Saudi Arabia had signed a contract for up to 150 Mi-35 and Mi-17 helicopters worth $2.2billion.[2]
On 28 October 2008. Royal Thai Army is proposes deal to buy 6 Mi-17 to meet its requirement of medium-lift helicopter. This is the first time in history Thai military buys aircraft from Russia. [3]
A licensed production of the Mi-17 will start in China with production being led by Mil Moscow Helicopter Plant JSC and the Sichuan Lantian Helicopter Company Limited in Chengdu, Sichuan province[4].
On 15th December 2008, Defense News reported that India will purchase 80 Mi-17IV helicopters which will be delivered to Indian Air Force between 2010 and 2014. These will replace aging Mi-8s.
On June 11, 2009, it was announced that the United States handed over four MI-17 cargo helicopters to the Pakistan Army to facilitate its counter-terrorism operation.

C-130 Hercules

The Lockheed C-130 Hercules is a four-engine turboprop military transport aircraft built by Lockheed. It is the main tactical airlifter for many military forces worldwide. Over 40 models and variants of the Hercules serve with more than 50 nations. In December 2006 the C-130 became the fifth aircraft—after the English Electric Canberra, B-52 Stratofortress, Tupolev Tu-95, and KC-135 Stratotanker—to mark 50 years of continuous use with its original primary customer, in this case, the United States Air Force. The C-130 is also the only military aircraft to remain in continuous production for 50 years with its original customer, as the updated C-130J Super Hercules.
Capable of takeoffs and landings from unprepared runways, the C-130 was originally designed as a troop, medical evacuation, and cargo transport aircraft. The versatile airframe has found uses in a variety of other roles, including as a gunship, for airborne assault, search and rescue, scientific research support, weather reconnaissance, aerial refueling, maritime patrol and aerial firefighting. The Hercules family has the longest continuous production run of any military aircraft in history. During more than 50 years of service the family has participated in countless military, civilian and humanitarian aid operations.
The Korean War, which began in June 1950, showed that World War II-era transports—C-119 Flying Boxcars, C-47 Skytrains and C-46 Commandos—were inadequate for modern warfare. Thus on 2 February 1951, the United States Air Force issued a General Operating Requirement (GOR) for a new transport to Boeing, Douglas, Fairchild, Lockheed, Martin, Chase Aircraft, North American, Northrop, and Airlifts Inc. The new transport would have a capacity for 92 passengers, 72 combat troops or 64 paratroopers, a range of 1,100 nmi (1,300 mi; 2,000 km), takeoff capability from short and unprepared strips, and the ability to fly with one engine shut down.
Fairchild, North American, Martin and Northrop declined to participate. The remaining five companies tendered a total of ten designs: Lockheed two, Boeing one, Chase three, Douglas three, Airlifts Inc. one. The contest was a close affair between the lighter of the two Lockheed (preliminary project designation L-206) proposals and a four-turboprop Douglas design.

Shenyang J-8

The effort to develop an all-weather interceptor began in full in 1964 and this produced the first Chinese-designed and built jet fighter to combat new, high altitude threats such as the B-58 Hustler, F-105 Thunderchief bombers and Lockheed U-2 spy planes. In 1964 the People's Liberation Army Air Force requested an aircraft from Shenyang Aircraft Corporation and the 601 Institute to develop a fighter/interceptor to counter bombers and spy planes as the, then, newly introduced Chengdu J-7 (a reverse engineered MiG-21F-13) was incapable of doing so. The prototype took its maiden flight in 1969. Despite the early mid to late 1960s origins of the J-8, due to political turmoils such as the Cultural Revolution, the J-8 was not produced until 1979 and entered service in 1980. Its basic configuration resembles an enlargement of the delta-wing of the J-7, with two Liyang (LMC) Wopen-7A turbojet engines and a maximum speed of Mach 2.2. The twin engined J-8 competed with rival Chengdu Aircraft Industry Group's single, turbofan powered engine, canard-delta J-9 project and ultimately emerged as the victor largely due to the existing availability of the former's MiG-21 based powerplant and proven layout, while the J-9 project was cancelled in 1980 due to diffculty in creating a suitably powerful engine.
In order to house a large radar set, the design called for a solid nose and variable geometry side air intakes. However, the lack of familiarity with this type of intake meant the J-8 had to settle for a MiG-21 style nose intake. The solid nose J-8 was finally realized in the J-8II (Finback-B), which was based on the layout of the Soviet Sukhoi Su-15 Flagon-A fighter. The radar chosen for the J-8 was the Type 204 mono-pulse fire-control radar, a primitive ranging radar for daylight within-visual-range operations. The performance of the radar fell well short of the PLAAFs requirements as research into a more capable fire control radar and power source proved difficult and time-consuming. The aircraft was originally armed with cannons and seven hardpoints for missiles, bombs, rockets or fuel tanks. The original weapons layout of the J-8 was two 30 mm Type 30-1 cannons after initial problems with the 30 mm Type 30-II four-barrel Gatling gun. The J-8 was also planned to be armed with the experimental PL-4 medium ranged missile but technical issues and political upheavals prevented any indepth development and the project was cancelled in 1985 citing unsatisfactory performance. Therefore the PL-2 IR-homing short-range anti-aircraft missile (SRAAM) was used instead. Unguided bombs and rockets can also be carried on the J-8.
