AH-64 Apache

The Boeing AH-64 Apache is an American four-blade, twin-turboshaft attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew. It features a nose-mounted sensor suite for target acquisition and night vision systems. It is armed with a 30 mm (1.18 in) M230 chain gun carried between the main landing gear, under the aircraft's forward fuselage. It has four hardpoints mounted on stub-wing pylons, typically carrying a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods. The AH-64 has a large amount of systems redundancy to improve combat survivability.

The Apache originally started as the Model 77 developed by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the AH-1 Cobra. The prototype YAH-64 was first flown on 30 September 1975. The U.S. Army selected the YAH-64 over the Bell YAH-63 in 1976, and later approved full production in 1982. After purchasing Hughes Helicopters in 1984, McDonnell Douglas continued AH-64 production and development. The helicopter was introduced to U.S. Army service in April 1986. The first production AH-64D Apache Longbow, an upgraded Apache variant, was delivered to the Army in March 1997. Production has been continued by Boeing Defense, Space & Security; over 2,000 AH-64s have been produced to date.

The U.S. Army is the primary operator of the AH-64; it has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands, Singapore, and the United Arab Emirates; as well as being produced under license in the United Kingdom as the AgustaWestland Apache. American AH-64s have served in conflicts in Panama, the Persian Gulf, Kosovo, Afghanistan, and Iraq. Israel used the Apache in its military conflicts in Lebanon and the Gaza Strip; British and Dutch Apaches have seen deployments in Afghanistan and Iraq.

The AH-64 Apache has a four-blade main rotor and a four-blade tail rotor. The crew sits in tandem, with the pilot sitting behind and above the copilot/gunner. Both crew members are capable of flying the aircraft and performing methods of weapon engagements independently. The AH-64 is powered by two General Electric T700 turboshaft engines with high-mounted exhausts on either side of the fuselage. Various models of engines have been used on the Apache; those in British service use engines from Rolls-Royce instead of General Electric. In 2004, General Electric Aviation began producing more powerful T700-GE-701D engines, rated at 2,000 shp (1,500 kW) for AH-64Ds.

The crew compartment has shielding between the cockpits, such that at least one crew member can survive hits. The compartment and the rotor blades are designed to sustain a hit from 23 mm (0.91 in) rounds. The airframe includes some 2,500 lb (1,100 kg) of protection and has a self-sealing fuel system to protect against ballistic projectiles. The aircraft was designed to meet the crashworthiness requirements of MIL-STD-1290, which specifies minimum requirement for crash impact energy attenuation to minimize crew injuries and fatalities. This was achieved through incorporation of increased structural strength, crashworthy landing gear, seats and fuel system.

Avionics and targeting

One of the revolutionary features of the Apache was its helmet mounted display, the Integrated Helmet and Display Sighting System (IHADSS); among its capabilities, either the pilot or gunner can slave the helicopter's 30 mm automatic M230 Chain Gun to their helmet, making the gun track head movements to point where they look. The M230E1 can be alternatively fixed to a locked forward firing position, or controlled via the Target Acquisition and Designation System (TADS). On more modern AH-64s, the TADS/PNVS has been replaced by Lockheed Martin's Arrowhead (MTADS) targeting system.

U.S. Army engagement training is performed under the Aerial Weapons Scoring System Integration with Longbow Apache Tactical Engagement Simulation System (AWSS-LBA TESS), using live 30 mm and rocket ammunition as well as simulated Hellfire missiles. The Smart Onboard Data Interface Module (SMODIM) transmits Apache data to an AWSS ground station for gunnery evaluation. The AH-64's standard of performance for aerial gunnery is to achieve at least 1 hit for every 30 shots fired at a wheeled vehicle at a range of 800–1,200 m (870–1,310 yd).

The AH-64 was designed to perform in front-line environments, and to operate at night or day and during adverse weather conditions. Various sensors and onboard avionics allows the Apache to perform in these conditions; such systems include the Target Acquisition and Designation System, Pilot Night Vision System (TADS/PNVS), passive infrared countermeasures, GPS, and the IHADSS. In August 2012, 24 U.S. Army AH-64Ds were equipped with the Ground Fire Acquisition System (GFAS), which detects and targets ground-based weapons fire sources in all-light conditions and with a 120° Visual field. The GFAS consists of two sensor pods working with the AH-64's other sensors, a thermographic camera precisely locates ground-based threats.

In 2014, it was announced that new targeting and surveillance sensors were under development to provide high-resolution color imagery to crews, replacing older low definition black-and-white imaging systems. In 2014, the U.S. Army was adapting its Apaches for increased maritime performance as part of the Pentagon's rebalance to the Pacific. Additional avionics and sensor improvements includes an extended-range radar capable of detecting small ships in littoral environments, software adaptions to handle maritime targets, and adding Link 16 data-links for better communications with friendly assets.

United States Army

Early service

The U.S. Army formally accepted its first production AH-64A in January 1984 and training of the first pilots began later that year. The first operational Apache unit, 7th Battalion, 17th Cavalry Brigade, began training on the AH-64A in April 1986 at Fort Hood, Texas. Two operational units with 68 AH-64s first deployed to Europe in September 1987 and took part in large military exercises there.

Upon fielding the Apache, capabilities such as using the FLIR for extensive night operations made it clear that it was capable of operating beyond the forward line of own troops (FLOT) that previous attack helicopters were normally restricted to. It was discovered that the Apache was coincidentally fitted with the Have Quick UHF radio system used by the U.S. Air Force, allowing inter-service coordination and joint operations such as the joint air attack teams (JAAT). The Apache have operated extensively with close air support (CAS) aircraft such as the USAF's Fairchild Republic A-10 Thunderbolt II and the USMC's McDonnell Douglas AV-8B Harrier II, often acting as a target designator to conserve the Apache's own munitions. The Apache was first used in combat in 1989, during Operation Just Cause, the invasion of Panama. The AH-64 participated in over 240 hours of combat attacking various targets, mostly at night. General Carl Stiner, the commander of the operation, commented that: "You could fire that Hellfire missile through a window from four miles away at night".

Nearly half of all U.S. Apaches were deployed to Saudi Arabia following Iraq's invasion of Kuwait. During Operation Desert Storm on 17 January 1991, eight AH-64As guided by four MH-53 Pave Low IIIs destroyed part of Iraq's radar network in the operation's first attack, allowing aircraft to evade detection. The Apaches each carried an asymmetric load of Hydra 70 flechette rockets, Hellfires, and one auxiliary fuel tank. During the 100-hour ground war a total of 277 AH-64s took part, destroying 278 tanks, numerous armored personnel carriers and other Iraqi vehicles. One AH-64 was lost in the war, to an RPG hit at close range, the Apache crashed but the crew survived. To maintain operations, the U.S. Army unofficially grounded all other AH-64s worldwide; Apaches in the theatre flew only one-fifth of the planned flight-hours.

The AH-64 played roles in the Balkans during separate conflicts in Bosnia and Kosovo in the 1990s. During Task Force Hawk, 24 Apaches were deployed to a land base in Albania in 1999 for combat in Kosovo. These required 26,000 tons of equipment to be transported over 550 C-17 flights, at a cost of US$480 million. During these deployments, the AH-64 encountered problems such as deficiencies in training, night vision equipment, fuel tanks, and survivability. On 27 April 1999, an Apache crashed during training in Albania due to a failure with the tail rotor, causing the fleet in the Balkans to be grounded in December 2000.

In 2000, Major General Dick Cody, 101st Airborne's commanding officer, wrote a strongly worded memo to the Chief of Staff about training and equipment failures. No pilots were qualified to fly with night vision goggles, preventing nighttime operations. The Washington Post printed a front-page article on the failures, commenting: "The vaunted helicopters came to symbolise everything wrong with the Army as it enters the 21st century: Its inability to move quickly, its resistance to change, its obsession with casualties, its post-Cold War identity crisis". No Apache combat missions took place in Kosovo due to fears of casualties.

Afghanistan and Iraq

U.S. Apaches served in Operation Enduring Freedom in Afghanistan from 2001. The Apache was the only Army platform capable of providing accurate CAS duties for Operation Anaconda, regularly taking fire during the intense early fighting, they were typically repaired quickly. U.S. AH-64Ds typically flew in Afghanistan and Iraq without the Longbow Radar in the absence of armored threats. On 21 December 2009, a pair of U.S. Apaches attacked a British-held base in a friendly fire incident, killing one British soldier. In 2006, Thomas Adams noted that Apaches often fought in small teams with little autonomy to react to threats and opportunities, requiring lengthy dialogue with command structures in an effort to centrally micromanage each unit.

In 2003, the AH-64 participated in the invasion of Iraq during Operation Iraqi Freedom. On 24 March 2003, 31 Apaches were damaged, and one shot down and captured, in an unsuccessful attack on an Iraqi Republican Guard armored brigade near Karbala. Iraqi tank crews had set up a "flak trap" among terrain and effectively employed their guns. Iraqi officials claimed a farmer with a Brno rifle shot down the Apache, but the farmer denied involvement. The helicopter came down intact and both the pilot and co-pilot were captured. The AH-64D was destroyed via air strike the following day.

By the end of U.S. military operations in Iraq in December 2011, several Apache helicopters had been shot down by enemy fire, and others lost in accidents. In 2006, an Apache was downed by a Soviet-made Strela 2 (SA-7) in Iraq, despite the Apache being typically able to avoid such missiles. In 2007, four Apache helicopters were destroyed on the ground by insurgent mortar fire using web-published geotagged photographs taken by soldiers. Several AH-64s were lost to accidents in Afghanistan as of 2012. Most Apaches that took heavy damage were able to continue their missions and return safely.

Recent service

As of 2011, the U.S. Army Apache fleet had accumulated more than 3 million flight hours since the first prototype flew in 1975. A DOD audit released in May 2011, found that Boeing had significantly overcharged the U.S. Army on multiple occasions, ranging from 33.3 percent to 177,475 percent for routine spare parts in helicopters like the Apache.

On 21 February 2013, the 1st Battalion (Attack), 229th Aviation Regiment at Joint Base Lewis-McChord became the first U.S. Army unit to field the AH-64E Apache Guardian; a total of 24 AH-64E were received by mid-2013. On 27 November 2013, the AH-64E achieved initial operating capability (IOC). In March 2014, the 1st-229th Attack Reconnaissance Battalion deployed 24 AH-64Es to Afghanistan in the type' first combat deployment. From April through September 2014, AH-64E in combat maintained an 88 percent readiness rate. The unit's deployment ended in November 2014, with the AH-64E accumulating 11,000 flight hours, each helicopter averaging 66 hours per month. The AH-64E flies 20 mph (32 km/h) faster than the AH-64D, cutting response time by 57 percent, and has better fuel efficiency, increasing time on station from 2.5-3 hours to 3-3.5 hours; Taliban forces, which were familiar with the AH-64D and based their tactics accordingly, were surprised by the AH-64E arriving and attacking sooner and for longer periods. AH-64Es also worked with medium and large unmanned aerial vehicles (UAVs) to find targets and maintain positive ID, conducting 60 percent of the unit's direct-fire engagements in conjunction with UAVs; Guardian pilots often controlled UAVs and accessed their video feeds to use their greater operating altitudes and endurance to see the battlespace from standoff ranges.

The Army is implementing a plan to move all Apaches from the Army Reserve and National Guard to the active Army to serve as scout helicopters to replace the OH-58 Kiowa. Using the AH-64 to scout would be less expensive than Kiowa upgrades or purchasing a new scout helicopter. AH-64Es can control UAVs like the MQ-1C Grey Eagle to perform aerial scouting missions; a 2010 study found the teaming of Apaches and UAVs was the most cost-effective alternative to a new helicopter and would meet 80 percent of reconnaissance requirements, compared to 20 percent with existing OH-58s and 50 percent with upgraded OH-58s. National Guard units, who would lose their attack helicopters, criticized the proposal. In March 2015, the first heavy attack reconnaissance unit was formed, comprising 24 attack Apaches, 24 reconnaissance Apaches, and 12 Shadow UAVs.

In July 2014, the Pentagon announced that Apaches had been dispatched to Baghdad to protect embassy personnel from Islamic State militant attacks. On 4 October 2014, Apaches began performing missions in Operation Inherent Resolve against Islamic State ground forces. In October 2014, U.S. Army AH-64s and Air Force fighters participated in four air strikes on Islamic State units northeast of Fallujah.


The Israeli Air Force (IAF) first received AH-64As in 1990, for a total fleet of 42. There was some controversy over the Air Force's choice to purchase Apaches over upgrading existing AH-1 Cobra attack helicopters. In 2000, Israel was interested in acquiring up to 48 AH-64Ds, but U.S. reluctance to share the software source code complicated the prospect. In April 2005, Boeing delivered the first AH-64D to the IAF. In 2001, the U.S. government was allegedly investigating misuse of the Apache and other US-supplied military equipment against Palestinian leaders and facilities. In 2009, an arranged sale of six AH-64Ds was reportedly blocked by the Obama Administration, pending interagency review, over concerns the helicopters may pose a threat to civilian Palestinians in Gaza. In IAF service, the AH-64A was named as the Peten (Hebrew: ????, for Cobra), while the AH-64D was named Saraph (???, also as "Seraph", Hebrew for venomous/fiery winged serpent).

During the 1990s, Israeli AH-64As frequently attacked Hezbollah outposts in Lebanon. On 13 April 1996, during Operation Grapes of Wrath, an Apache fired two Hellfire missiles at an ambulance in Lebanon, killing six civilians. During the al-Aqsa Intifada in 2000, AH-64s were used to kill senior Hamas figures, such as Ahmed Yassin and Adnan al-Ghoul. On 24 May 2001, a privately owned Lebanese-registered Cessna 152 flew into Israeli airspace, it was intercepted by two AH-64s and shot down by a Hellfire missile, killing the pilot. On 22 March 2004, an Israeli AH-64 used a Hellfire missile to kill Hamas leader Ahmed Yassin, also killing his two bodyguards and nine bystanders. IAF Apaches played a prominent role in the 2006 Lebanon War, launching strikes into Lebanon targeting Hezbollah forces.

There have also been accidents involving the Apache helicopter in Israeli service. During the Lebanon War in 2006, two IAF AH-64A helicopters collided, killing one pilot and critically wounding three. In another incident in the conflict an IAF AH-64D crashed due to a malfunction in the main rotor, killing the two crew. In late 2007, the Israeli Air Force put further purchases and deliveries of AH-64Ds on hold during an investigation upon the aircraft's performance envelope. However, Israeli officials have since praised the Apache for its role in Operation Cast Lead in 2008, against Hamas in Gaza. In recent years, Israeli Apaches have been used to patrol the skies over Gaza; strike operations against insurgents using these helicopters has become a frequent occurrence.

Since recent orders of new AH-64Ds have been blocked, Israel has pursued upgrades to its AH-64A fleet. In June 2010, Israel decided not to upgrade all AH-64As to D configuration, due to funding constraints and lack of U.S. cooperation. In December 2010, the IAF was examining the adoption of a new missile system as a cheaper and lightweight complement to the Hellfire missile, either the American Hydra 70 or the Canadian CRV7. In 2013, Israeli AH-64As had been receiving a comprehensive upgrade of their avionics and electrical systems. The AH-64As are being upgraded to the AH-64Ai configuration, which is near the AH-64D standard.

United Kingdom

The UK operates a modified version of the Apache Longbow initially called the Westland WAH-64 Apache, and is designated Apache AH1 by the British Army. Westland built 67 WAH-64 Apaches under license from Boeing, following a competition between the Eurocopter Tiger and the Apache for the British Army's new Attack Helicopter in 1995. Important deviations made by AgustaWestland from the U.S. Apache variants include changing to more powerful Rolls-Royce engines, and the addition of a folding blade assembly for use on naval ships.

The Dutch government initially showed an interest in acquiring Apache helicopters in the late 1980s, where it stated that it may purchase as many as 52. A competition held in 1994 against the Eurocopter Tiger and the Bell AH-1 SuperCobra led to the Royal Netherlands Air Force ordering 30 AH-64D Apaches in 1995. Deliveries began in 1998 and ended in 2002. The RNLAF Apaches are equipped with the Apache Modular Aircraft Survivability Equipment (AMASE) self-protection system to counter infrared (IR) missile threats.

The RNLAF Apaches' first deployment was in 2001 to Djibouti, Africa. They were also deployed alongside U.S. AH-64s in support of NATO peacekeeping forces in Bosnia and Herzegovina. In 2004, six Dutch AH-64s were deployed as part of the Netherlands contribution to Multinational force in Iraq to support the Dutch ground forces. The Apaches performed close combat support and display of force missions, along with providing reconnaissance information to ground forces. In February 2006, the Netherlands contribution to NATO forces in Afghanistan was increased from 600 to 1,400 troops and 6 AH-64s were sent in support.

Shortly after Apaches were deployed to Hamid Karzai International Airport, as part of the Netherlands contribution to ISAF, on 10 April 2004 a pair of Dutch Apaches came under light gunfire close to the Afghan capital. On 17 December 2007, an RNLAF Apache flew into powerlines during a night flying exercise in the Netherlands, forcing an emergency landing and causing a lengthy blackout in the region. On 17 March 2015 a RNLAF Apache crashed during a training mission in Mali. Both pilots died. The ministry of defence opened an investigation into the cause of the crash.

Saudi Arabia

Following the 1991 Gulf War, during which many U.S. Apaches operated from bases within Saudi territory, Saudi Arabia purchased twelve AH-64As for the Royal Saudi Land Force. It has been speculated that the Saudi purchase had motivated Israel to also procure the Apaches. In August 2006, the Saudi Arabian government began negotiations for Apache upgrades worth up to $400M, possibly remanufacturing their AH-64As to the AH-64D Longbow configuration. In September 2008, the U.S. Government approved the purchase of 12 AH-64Ds requested by Saudi Arabia. In October 2010, Saudi Arabia requested a further 70 AH-64Ds as part of a possible, massive arms deal.

In November 2009, the Royal Saudi Land Force, as part of a military effort against insurgent intrusions of the kingdom's border, started using the Apache in Operation Scorched Earth; this involved launched air strikes against Houthi rebels operating inside neighboring Yemen as well. In January 2010 the rebels claimed to have shot down an Apache; this was denied by the Saudi military. In late January 2010, the leader of the Shiite rebels announced their withdrawal from Saudi territory, this announcement followed a key battle on 12 January when Saudi forces reportedly took control of the border village of Al Jabiri.


In 1995, the Egyptian Air Force placed an order for 36 AH-64A helicopters. These Apaches were delivered with most of the advanced avionics used on the U.S. fleet at that time, with the exception of localized radio equipment. In 2000, Boeing announced an order to remanufacture Egypt's existing Apache fleet to the AH-64D configuration. Notably, the AH-64D upgrade did not include the procurement of the Longbow radar, the supply of which had been refused by the U.S. government. Egypt requested a further 12 AH-64D Block II Apaches through a Foreign Military Sale in 2009.

In August 2012, the Egyptian Armed Forces undertook a large-scale military operation to regain control of the Sinai Peninsula from armed militants. Air cover throughout the operation was provided by the Egyptian Air Force's Apache helicopters; reportedly the Apaches destroyed three vehicles and killed at least 20 militants. Up to five Egyptian Apaches were temporarily stationed in the Sinai following an agreement between Egypt and Israel. In September 2015, an Egyptian Apache attacked a group of foreign tourists in the Egyptian part of the Libyan Desert, killing 12 people and injuring 10, they were mistaken for Islamist militants, the Egyptian Interior Ministry stated that the group were in a restricted area.

Other users

The United Arab Emirates purchased 30 AH-64A helicopters in 1991 and 1994, which they are now upgrading to AH-64D specification. In 2005, Kuwait purchased 16 Longbow helicopters.

Greece received 20 AH-64As by 1995; another 12 AH-64Ds were ordered in September 2003.

Singapore purchased 20 AH-64Ds aircraft in two batches between 1999 and 2001; during October 2010 Apache training was suspended following the forced crash-landing of an Apache.

Japan ordered 50 AH-64Ds, which are being built under license by Fuji Heavy Industries, designated "AH-64DJP". The first helicopter was delivered to the JGSDF in early 2006.

Taiwan (Republic of China) reached an agreement with the U.S. to purchase 30 AH-64Es with weapons, and associated equipment in June 2011. On 5 November 2013, Taiwan received the first 6 AH-64s. On 25 April 2014, a Taiwanese AH-64E crashed into a three-story building during a training flight in bad weather conditions, the first airframe loss of an AH-64E. An investigation ruled out mechanical failure and concluded human error as responsible, that the pilots descended too fast through clouds at low altitude without checking flight panels to maintain adequate height; the Army responded by stepping up simulator training for pilots. In October 2014, the fifth and final batch of AH-64Es was delivered to Taiwan, completing the order.

Future and possible users

In 2008, the Indian Air Force (IAF) released a tender for 22 attack helicopters; there were six contending submissions—Sikorsky's UH-60 Black Hawk, the AH-64D, Bell's AH-1 Super Cobra, Eurocopter's Tiger, Mil's Mi-28 and AgustaWestland's A129 Mangusta. In October 2008, Boeing and Bell withdrew. In 2009, the competition was restarted. In December 2010, India requested the possible sale of 22 Apaches and associated equipment. On 5 October 2012, IAF Chief NAK Browne confirmed the Apache's selection. The IAF sought control of the 22 proposed Apaches for air combat missions, while the Army Aviation Corps argued that they would be better used in army operations. In April 2013, the Indian Ministry of Defence (MoD) decided that the IAF would receive the 22 AH-64s. In May 2013, the Indian Army requested 11 AH-64Es; and has a requirement for 39 Apaches. The Indian Ministry of Defence approved the procurement in August 2014, as did India's Cabinet Committee on Security (CCS) in September 2015. On 28 September 2015, a contract was formally signed; the first helicopter is expected to be delivered to India in the next three to four years.

In 2009, South Korea showed interest in acquiring Apaches. This move may be related to U.S. plans to withdraw many of its Apaches from South Korea. On 21 September 2012, the U.S. Congress was notified of the possible purchase of 36 AH-64D Block III Apaches, along with associated equipment and armament. The Apache competed against the Bell AH-1Z Viper and the TAI/AgustaWestland T-129; in April 2013, South Korea announced that it is to purchase 36 AH-64Es. The Apaches are to be delivered from 2016 to 2018.

On 26 August 2013, the U.S. and Indonesia formalized a $500 million deal for 8 AH-64E Apaches.

Iraq requested the sale of 24 AH-64s in April 2013; In January 2014, a sale, including the helicopters, associated parts, maintenance, and training, was cleared by Congress. However, the proposal was not accepted by the Iraqi government and expired in August 2014.

In July 2012, Qatar requested the sale of 24 AH-64D Apache Block III helicopters, with associated equipment, training, and support. The sale was approved on 27 March 2014.
