AW129 Multi-Role Combat Helicopter, Italy

The AW129 multirole combat helicopter is the latest variant of the A129 Mangusta (Mongoose) helicopter in service with the Italian Army. It is manufactured by AgustaWestland, a joint venture company, which was originally formed by Finmeccanica of Italy and GKN of the UK, but is now solely owned by Finmeccanica.

The A129 International was renamed AW129 in 2007. The AW129 is a multirole helicopter for armed reconnaissance and surveillance, high-value ground-target engagement, escort, fire support and air-threat suppression. It is armed with powerful air-to-ground and air-to-air missiles, an off-axis cannon and an increased weapon payload. The five-bladed A129 International also has more powerful engines than the four-bladed Mangusta.

The AW129 is able to self-deploy over 1,000km, using external fuel tanks while carrying four air-to-air missiles for self-protection. The helicopter is air transportable by C-130 and larger transport aircraft.

A129 Mangusta helicopter upgrade

The Italian Army is equipped with 60 A129 Mangusta helicopters and 15 AW129, referred to as A129 CBT (combat configuration).

In January 2002, AgustaWestland was awarded a contract to upgrade the first 45 to the multirole standard.

The Mangusta were successfully deployed with UN operations in Somalia, Angola and Kosovo. Italian Army A129 helicopters have been deployed in Iraq as part of Operation Iraqi Freedom and were deployed to Afghanistan in summer 2007, as part of the Nato International Security Force.

Turkish T129 variant

In September 2007, Turkey placed an order for 51 (plus 41 options) A129 helicopters for the attack and tactical reconnaissance (ATAK) programme. Tusas Aerospace Industries (TAI) is the prime contractor and is responsible for final assembly of the helicopter, which will be designated T129. AgustaWestland and Aselsan are the main subcontractors.

The maiden flight of the T129 helicopter took place on 28 September 2009 during an official ceremony held at AgustaWestland’s facility in Vergiate, Italy. Deliveries are expected to begin in 2012.

In November 2010, Turkey placed a $205m order with AgustaWestland for nine T129 combat helicopters and spare parts. Deliveries are scheduled to be completed by mid-2012.

AgustaWestland has now completed development and testing of upgraded weapons and target acquisition systems for the ARH-129D aerial reconnaissance helicopter, the latest version of the attack-variant AW129 Mangusta. The company has also completed the first flight of the T129, an upgraded AW129 being modified to meet the needs of the Turkish Land Forces Command’s ATAK (tactical reconnaissance and attack helicopter) program.

The most recent testing for the ARH-129D was conducted in Sardinia using a prototype. A major part of the testing for the aircraft was to ensure the compatibility of the aircraft’s laser systems—laser designator (LD), laser range finder (LRF), laser marker (LM) and laser spot detector (LSD)—with the electronic warfare and SIAP (single integrated air picture) self-protection suite, the company noted. Trials also verified the overall architecture and man-machine interface, the co-pilot/gunner dual hand-grip and head-up display (HUD) firing symbology.

The SPIKE-ER, formerly known as the NTD, is a multi-platform anti-tank missile with an extended range over previous SPIKE missiles. It has been designed to be mounted on ground vehicles, helicopters, and naval vessels. It seeker combines electro-optical sensors (IR/CCD-TV) and a fiber optic data link to achieve fire and forget and directed launch modes. Using the fiber optic data link the SPIKE-ER missile is able to perform battle damage assessment, in-flight retargeting, identification friend or foe, attacks without collateral damage and pinpoint accuracy strikes.

In June 2004, EuroSpike GmbH, a joint venture between Diehl (40%), Rheinmetall (40%), and Rafael (20%), was created to support Spike family of anti-armor missiles sales to European customers.

The SPIKE-ER missile operates day/night, in all weather conditions. Its tandem warhead ensures neutralization of ERA (Explosive Reactive Armor) protected targets. A single missile launcher weighs about 58 kg, and the 4-missile launcher for helicopters weighs 187 kg. A wooden round SPIKE-ER missile weighs 33 kg.

The SPIKE-ER long range anti-tank missile is currently deployed in Israel Armed Forces. The SPIKE-ER is the Israeli counterpart to proven Hellfire long range anti-tank missile.

AgustaWestland said that the drift on the multi-function control display, when passing from the sight unit to the missile image, has been reduced, adding that the precision on the TM-197B machine guns that had been achieved with the older HeliTOW sighting unit was re-established.

Designers have also retained the tracking launch rails for missile firings to allow changes in the elevation of the missiles to be launched, rather than having to change the attitude of the aircraft. During the trials, the ARH-129D prototype was used to designate a target, the first time employing an Italian Army helicopter rather than a fixed-wing Italian Air Force aircraft. The IAF dropped Lizard-guided bombs from its AMX training/light attack aircraft in both a stabilized flight profile at 15,000 feet and in a dive profile released between 10,000 and 8,000 feet. Tests were done with the ARH-129D’s LD locking onto the bombs in order to send to targets both before and after launch. Israel-based Elbit Systems makes the Lizard, and relies on a semi-active laser guided kit to hit the target. The company said that the laser designator will allow the aircraft to use 2.75-inch guided rockets or “smart” 155 mm artillery shells.

AgustaWestland plans to modify a total of 24 AW129 Mangustas into ARH-129Ds, followed by another 24 new builds, which will have further upgrades in terms of powerplants and computer capabilities. The Italian Army currently has 59 AW129s.

AgustaWestland has announced that its program to provide 60 T129s to the Turkish LFC is “progressing on time and on budget.” Delivery of nine early supplemental A129s is scheduled to begin in mid-2012, with the unit scheduled to receive 51 T129s starting in 2013. The first nine helicopters are intended for immediate operational needs and will have less powerful engines, simpler weapons systems and non-Turkish avionics. However, there are plans to upgrade these aircraft at some point in the future.

First flight of one of the T129 prototypes (P3) took place on March 11 in Vergiate, Italy. The first prototype (P6) developed by the full ATAK team is expected to fly “shortly,” the company said. The ATAK team consists of Turkish Aerospace Industries (TAI)—the prime contractor and system integrator—while AgustaWestland and Aselsan are the main subcontractors. ATAK placed an order for 51 T129s in September 2007. In November of last year, it placed a €150 million ($213.3 million) order for an additional nine, bringing total orders to 60 aircraft, plus 41 options.

A total of six prototypes are being built, with three assembled in Italy dedicated to the development of the basic vehicle, and three assembled in Turkey dedicated to mission systems test and evaluation.

Evaluation testing of the ASELFLIR 300 targeting system and the upgraded turreted gun system has already been conducted, with initial product support, offset and technology transfer activities progressing on schedule, according to the company. Source aviationtoday.com

Italy deploys Helicopter Force (including AW-129 Mangusta attack choppers) to Iraq: Here

Excerpt

This is the not the first time the Italian Mangustas (that have extensively been used in Afghanistan) are deployed to Iraq: the Italian Army operated the A-129 (a previous variant of the current AW-129D) in Iraq from 2003 to 2006, supporting the Italian Contingent based at Nassiryah.

The AW-129D is the latest variant of the A129 attack helicopter equipped with infrared night vision systems, laser systems for range-finding and target designation purposes, OTSWS (Observation, Targeting and Spike Weapon System) for Spike-ER missile guidance in fire-and-forget and fire-and-observe modes.

Cockpit

Weapons on the AW129

The A129 International helicopter can be armed with Raytheon Stinger or MBDA (formerly Matra BAe Dynamics) Mistral air-to-air missiles. Stinger missile certification was successfully completed on the Italian Army A129CBT in October 2003, using Stinger RMP block I missiles.

The helicopter has dual air-to-ground missile capability with the Lockheed Martin Hellfire or Raytheon TOW 2 missile or a mix of both, giving the gunner selective fire against low and high-value targets, and the capability of precise hits in urban environments. The Mangusta is fitted with the HeliTOW system for the TOW2A missile.

The AW129 also has dual rocket system capability, deploying 70mm rockets for ammunition commonality with Nato countries and 81mm rockets for longer-range engagements. The Mangusta can carry four 81mm rocket launchers. A 20mm three-barrel Gatling-type turreted cannon with 500 rounds of ammunition is mounted under the nose.

The TM 197B Light Turreted Gun System is designed for integration under the nose of combat and multi-role helicopters and features the General Dynamics M197 20mm Gatling gun.

The TM 197B  turret provides the helicopter with a weapon system suitable for air-to-ground and close range air-to-air combat missions, taking advantage of the performance of a 20mm gun with reduced weight and low profile, thus allowing a safe stand-off flight.

The TM 197B can be easily fitted into military helicopters, not originally  designed for the combat role.

20110112_rimini_07Image: ima-photo.com

The turret motion, in azimuth and elevation, is controlled by the pilot or the co-pilot/gunner by means of a Helmet and Display Sight System(which sense the position and the motion of the head of the two crew members) and/or by the Main Sight Unit of the Combat System of the helicopter.
Operation is possible at helicopter speeds up to 140 knots and the firing position is maintained under all critical flight and maneuver conditions.

The TM 197B turret provides flexible and fixed modes of fire. In case of aircraft or turret power failure the weapon returns to the fixed forward firing position and is automatically locked.  Source leonardocompany.com

FIM-92A Stinger Weapons System

atas_resize

The Stinger system consists of a Stinger round encased in its launch tube and a separate gripstock assembly.

The “fire-and-forget” Stinger missile employs a passive infrared seeker to home in on its airborne target. A passive infrared seeker emits no radiation that a target aircraft can detect, and, instead, guides on the infrared energy (heat) emitted by the target. Because the Stinger employs a passive homing seeker, it is a “fire-and-forget” weapon that needs no guidance from the operator after firing, unlike other missiles that track the reflection of a designator beam, requiring the operator to maintain a lock on the target. This allows a Stinger operator to take cover, relocate, or engage other targets immediately after firing a Stinger.

The Stinger system features a proportional navigation system, integrated Indentification Friend or Foe (IFF) interrogation, and threat adaptive guidance. Proportional navigation enables the missile to effectively hit moving targets by injecting a multiplier factor into course corrections so that the missile overcorrects for a target’s evasive maneuvers, leading the target to a successful interception. The integrated IFF subsystem allows the Stinger operator to query a target aircraft to determine if it is friendly. Before firing, the operator depresses a button on the gripstock assembly, emitting a coded radio signal. Aircraft equipped with friendly IFF systems will recognize the coded signal and respond with the appropriate coded reply. The IFF subsystem emits one tone if it authenticates a friendly aircraft, and another if the aircraft is unknown. The IFF subsystem is intended to prevent friendly-fire incidents. The Stinger’s threat adaptive guidance takesover in the final stages of its approach to the target, slightly shifting the missile’s aim from the target’s IR hotspot to more vulnerable areas of the aircraft.

The Air-to-Air Stinger [ATAS] is an adaption of the man portable Stinger System. It is a light weight missile designed to engage low altitude targets.

1390393195_atam_large

MISTRAL ATAM is based on the MISTRAL missile with its fire-and-forget engagement mode, ease of operation and unrivalled kill probability.

The system is based on two launchers, each bearing two missiles and can be connected to the helicopter’s combat system, when mounted on combat helicopters, or through simplified control equipment if installed on multi-purpose helicopters.

In both cases, it is characterised by simplicity of operation, a very low crew workload and a high level of performance.

The system can be operated within the whole flight envelope of the launch helicopter, at speeds of up to 200 knots and at altitudes exceeding 15,000 ft.

FEATURES

MISTRAL ATAM ensures a large off-boresight capability, together with the ability to aim the missile seeker very precisely at a given target.

The missile has a shaped trajectory in order to intercept targets top-down or at long range, the crew can also select the proximity fuze mode.

MISTRAL ATAM is currently the only helicopter mounted air-to-air missile in full operational service.

Countermeasures

The AW129’s electronic warfare suite includes an Elettronica ELT-156 radar warning receiver and a BAE Systems Italia RALM-101 laser warner.

Elettronica ELT-156 radar warning receiver

The ELT/156 family of light radar warning receivers is designed to provide self-protec­tion for utility and combat aircraft and helicopters. It protects the platform during operations in insecure areas, anti-tank missions, escort of ground vehicles.Today’s operational scenarios are characterised by a very dense electromagnetic environment, with the presence of increasingly advanced emitters and in which the same sensors can be equally used by both friendly and hostile platforms.

Also, recent conflicts and peace-keeping missions, with the participation of multinational forces, are further highlighting the urgent need for timely and more reliable threat awareness. Threat discrimination thus becomes an extremely crucial aspect of own-platform survivability and mission success.To meet the challenge posed by current needs, the ELT 156 family is designed to detect, analyse and identify all the electromagnetic emissions in an extremely short time and beyond the maximum weapon system engagement zone.

System Highlights

  • High Probability of Intercept
  • Full azimuth coverage
  • Wideband radio frequency coverage (E to K)
  • Automatic warning of high priority emitters
  • Capability to operate also with raw data libraries (mission data)
  • Lightweight
  • Flight line re-programmable
  • Easy field maintainability (LRU philosophy).

Some versions include dual-mode cockpit display (raw/synthetic). Some versions can be fully integrated with ECM systems and platform data bus.Upgrades include the capability to operate in presence of an internal or external EW controller that exploits/performs functions for multi-sensor coordination.

The helicopter countermeasures systems include Elettronica ELT-554 radar and BAE Systems IEWS AN/ALQ-144A infrared jammer and chaff and flare decoy dispensers.

Elettronica ELT-554 radar

The threat likely to be encountered by tactical combat aircraft over the target area comprises radar-controlled Anti Aircraft Artillery (AAA), Surface to Air Missiles (SAM), Air to Air Missiles (AAM), besides Early Warning and Search radars.The ELT/553 family of self-protection jammers exploits years of company consolidated experience, and is conceived to defeat the above defence assets thus increasing aircraft survivability and mission success.Light (e.g. without the low band module) or enhanced ELT/553 configurations offer ideal self-protection solutions to helicopters, large radar cross-section aircraft respectively and tactical combat aircraft covering roles involving ground and air threats.

The ELT/553 family is field proven and currently in service featuring:

  • Maximum flexibility, operating either fully integrated with onboard RWR, or in a back-up (stand-alone) mode
  • Automatic deception of pulse and CW coherent and non coherent radars (lock-on,
    TWS, Search); effectiveness even in the presence of advanced ECCM techniques.

System Highlights

  • Multi-threat effectiveness against staggered and jittered PRI emitters, as well as against frequency diversity/frequency agility threats
  • Automatic jamming of lock-on radars, even if unknown emitters
  • Easy programmability of receiver parameters and jamming sequences
  • Easy installation and full compatibility with other onboard avionics for a wide range of platforms.
