WAH-64 Longbow Apache

GKN Westland (now AgustaWestland), a consortium of Boeing, Lockheed Martin, Northrop Grumman, and Shorts Inc., bid for a version of the Longbow Apache for the British Army to attack helicopter requirements, which Was chosen in July 1995. WAH-64 Longbow Apache assembly in the UK by AgustaWestland.

The WAH-64 Longbow Apache assembly was conducted in the UK by Agusta Westland.
The first helicopter was put into use in January 2001 and was named AH mk1. 67 helicopters have been delivered; the last time in July 2004 at the Farnborough Air Show on the formal handover.

October 2004 to achieve the initial operational capability, in May 2005, 18 helicopters of the three Army Aviation Corps in the first unit declared full-scale operations. The other two teams are expected to be fully operational in 2010. AH mk1 helicopter is also successful in the HMS marine helicopter carrier ship, and in November 2006 in the Invincible class aircraft carrier HMS Ark Royal landing for the first time.

In March 2007, the British Ministry of Defense announced that by September 2007, all the British Army Apache helicopters will be located in Suffolk's Wadisim Air Force Base.

Apache Weapons:

A 30mm automatic Boeing M230 chain gun is located below the fuselage. It provides 625 fires per minute. Helicopters can accommodate up to 1200 rounds of ammunition.

The AH-64D is equipped with the Lockheed Martin / Boeing AGM-114D Longbow Hellfire-to-Surface Missile, which has a millimeter-wave detector that allows the missile to be executed in full fire and forget mode. The range is 8 km to 12 km.

"The helicopter can accommodate up to 1200 rounds of ammunition.

Apache can be equipped with air-to-air missiles (Stinger, AIM-9 Sidewinder, Mistral, and Sidearm) and the Advanced Precision Kill Weapon System (APKWS), previously known as Hydra, family oriented and unguided 70mm rockets. Plans to use the Advanced Precision Weapon System (APKWS) II to build Apache, Hydra laser guidance version of the fiscal year 2008 budget was shelved. The US Army awarded APKWS II a development contract for BAE Systems in April 2006.

The British Army AH mk1 helicopter is equipped with the CRV7 70mm rocket system from Bristol Aerospace, Winnipeg, Manitoba.

Longbow Apaches carry a combination of weapons selected for a particular mission. Under close support, the helicopter carried 16 Hellfire missiles on four four-rail launchers and four air-to-air missiles.

Sensor:

AH-64D Longbow Apache is equipped with Northrop Grumman Millimeter Wave Bow Radar. The Longbow Fire Control Radar incorporates an integrated radar frequency interferometer for passive positioning and identification of radar launch threats. The advantage of millimeter-wave is that it performs under low visibility conditions and is less susceptible to ground clutter. The short wavelength allows a very narrow beam width, which resists countermeasures.

Longbow Apache can attack in 30 seconds. The radar dome is shielded by a separate radar scan and then re-shielded. The processor determines the position, velocity, and direction of travel of up to 256 targets.

TADS (AN / ASQ-170) and Pilot Night Vision Sensor PNVS (AN / AAQ-11) were developed by Lockheed Martin. The turret-mounted TADS provides direct observation of optical, television and three-field forward-looking infrared (FLIR) to perform a search, detection, and identification, as well as Litton laser rangefinders/indicators. The PNVS consists of FLIRs in a rotating turret located above the nose on the TADS. Images from the PNVS are displayed in a monocular eyepiece by the Honeywell integrated helmet and IHADSS, which are worn by the pilot and co-pilot/gunner.

Lockheed Martin has developed a new aiming and night vision system for Apache that uses a second-generation long-wave infrared sensor with better range and resolution. The new system is called Arrowhead, FLIR with three fields of view, FLIR, CCD TV camera, electronic zoom, target tracker and automatic boresight.

Lockheed Martin has developed a new aiming and night vision system for Apache.

Arrowhead began production in December 2003 and the first unit was delivered to the US Army in May 2005. The first Arrowhead system was integrated into the Apache helicopter in June 2005. By 2011, a total of 704 US Army Apache equipped Arrowhead. The 500th delivery was completed in 2008 and the remaining deliveries were completed as planned. The US Army also provided Apache with a follow-on contract for additional Arrowhead accessories, adding to the total number of Army Arrowhead integrations.

UK AH Mk1 Helicopter Arrowhead contract was released in May 2005. The first two deliveries were delivered in November 2008 and the delivery was completed in 2010.

Countermeasures:

Apache is equipped with an electronic warfare suite that includes the AN / APR-39A (V) radar alarm receiver from Northrop Grumman (formerly Litton) and Lockheed Martin; the Lockheed Martin AN / APR-48A radar frequency interferometer electronics support target AN / AVR-2 laser warning receiver (Goodrich) (formerly Hughes Danbury Optical Systems, Inc., Raytheon); AN / ALQ-144 infrared countermeasures were set by BAE Systems IEWS (formerly Sanders, Lockheed Martin) ; AN / ALQ-136 (V) radar jammers developed by ITT; and chaff dispensers.

The US Army Longbow Apaches will be equipped with the ITT AN / ALQ-211 SIRCM (a comprehensive RF confrontation) suite, however, the funding availability of this project is uncertain.

United Kingdom AH mk1 Apaches are equipped with the BAE System Helicopter Integrated Defense Kit (HIDAS), also selected by Kuwait and Greece. HIDAS, including the Sky Guardian 2000 radar warning receiver, served in AH mk1 in July 2003.

Israeli AH-64D helicopters equipped with Elisa Seraph self-protection system, including SPS-65 missile aircraft and SPJ-40 radar jammers.

The Netherlands AH-64D helicopters are equipped with Northrop Grumman Directed Infrared Counter (DIRCM) pods.

Engine:

Apache is equipped with two turboshaft engines, each offering 1,265kW. United States AH-64D with General Electric T700-GE-701 engine, the United Kingdom with the Rolls-Royce / Turbomeca Apache from the RTM322 engine.

Performance:

AH-64 Apache can climb at 889 m / min. The maximum helicopter and cruise speeds were 279km / h and 260km / h. The helicopter ferry range and service ceilings were 1,900 kilometers and 6,400 meters, respectively. Stamina for 3 hours and 9 minutes. The helicopter weighs about 5,165 kg and has a maximum takeoff weight of 10,433 kg.
