IDEX has witnessed continuous regional and international interest in its sixth edition with confirmed bookings already from 43 countries for over 85 per cent of the indoor and outdoor exhibition space. On last count, some 700 companies confirmed participation in IDEX 2003, in a clear testimony of the event?Ts significance. The entire exhibition space is expected to be completely booked by December this year even as the high-level delegation from IDEX proceed with its presence at some of the most prestigious defence shows worldwide such as Asia Aerosapce in Singapore, DSA 2002 in Malaysia, ILA 2002 in Berlin, Germany and the IDEE 2002 in Slovak Republic. Worthy of its reputation as one of the biggest and most comprehensive defence shows in the world, IDEX 2003 will cover an area of 130,000 square metres, including indoor, outdoor and demonstration area at the sprawling and state-of-art Abu Dhabi International Exhibition Centre, providing exhibitors and visitors the best services and expertise. Historically, IDEX has been a major attraction for senior government and military delegations from GCC, MENA and practically around the world. Some 80 official delegations are likely to attend IDEX 2003. During the last IDEX 2001, four heads of State from friendly countries and more than 65 ministers of defence and decision makers attended. IDEX a Unique Show IDEX has won it self a global reputation in the world with some unique features such as its Al Maqatra live firing range. At the Al Maqatra field firing range, an arsenal of weaponry, artillery and missiles with ranges up to 20 Kms, are live-fired. Remarkably enough, IDEX is the only defence show in the world to permit the use of live ammunition in such demonstrations to maintain its position as the premier defence exhibition. Additionally, there is the 100,000 square metres mobility area for live demonstrations which features armoured tracked, wheeled vehicles and main battle tanks. Another feature is the dedicated naval berthing area at Abu Dhabi?Ts Mina Zayed Port to host naval vessels, warships, cruisers and submarines besides serving as a launching pad and demonstration area. While 15 companies from four countries will take part in the live-firing, some 13 companies will participate in the live demonstration with 18 shows. These companies will be able to demonstrate the full capabilities of their weapons and equipments allowing the visitors to have a first hand experience of these systems. Smaller naval and amphibious crafts can be demonstrated at an artificial marine canal adjacent to the main IDEX site. The artificial marina served as theatre for several underwater operation, fast patrol boats capabilities as well amphibious operations equipments in the past events. Following the success of the previous session, the Gulf Defence Conference will once again accompany IDEX 2003. The conference will be an excellent platform to discuss the region?Ts defence requirements and its vital security issues. The theme of the conference will be ?oDefence Strategies for the coming years?. The conference will also include several workshops that will tackle operational and business issues.Top defence experts and defence personnel and analysts will be addressing the conference. The previous edition, IDEX 2001 was a thumping success with some 865 companies from more than 40 countries participating. Important contracts negotiated and announced during IDEX 2001 included ones with the UAE alone worth US$ 255 million. This evident success is due in part to the strategic location of the UAE which enables it to host an event such as IDEX. Located in a vantage position between the East and the West, the UAE is also the undisputed regional gateway between the east and the west and a top-class trading hub. UAE is also well positioned among GCC and MENA countries, and maintains excellent balanced relationships with them. According to analysts, defence spending in the six Gulf States is expected to increase, more so in the aftermath of the September 11 events and the ongoing tension in the Middle East. Some US$ 30 billion was spent by the Gulf States in 1998 alone on defence and security and this is steadily rising as defence spending accounts for about 10 per cent of their GDP (Gross Domestic Product) according to the London-based Institute of International Strategic Studies. This makes IDEX the perfect platform for defence equipments and technology providers seeking to develop their markets in the region.

BMP-3 upgrades aimed at Middle East region

By Christopher F Foss

The Russian BMP-3 infantry combat vehicle (ICV), manufactured by the Kurgan Machine Construction Plant has been one of the best selling vehicles of its type in the Middle East, being operated by three AGCC countries.

The Russian company of Electromashina is marketing a number of BMP-3 upgrade packages to enhance the capabilities of the vehicle, especially in the harsh climate of the Middle East.

To improve its combat survivability, the BMP-3 shown at IDEX has been fitted with the Shtora TshU-1M defensive aid suite, which has been developed to decoy away anti-tank guided missiles (ATGM) fitted with a semi-automatic command-to-line of sight (SACLOS) guidance system. The system is mounted on the turret of the BMP-3 and covers the vital frontal arc.

In addition, the system protects the BMP-3 against laser guided missiles and missiles guided to the target using a laser designator. Laser detectors alert the crew to the threat and then the launchers mounted on either side of the turret are activated to rapidly counter the threat.

The vehicle has also been fitted with an air conditioning system in the crew and engine compartments and a automatic gear selector to make the drivers job easier. A Raduga-2 fire detection and suppression system has been installed in the engine and crew compartments.

The vehicle has also been fitted with the so-called Electronic Assistant for the Driver and Operator (EADO), while another electronic assistant is provided for the commander and gunner seated in the turret.

The main armament of the BMP-3 is a 100mm rifled gun that in addition to firing conventional types of ammunition can fire a laser guided projectile fitted with a tandem high explosive anti-tank (HEAT) warhead. The KBP Instrument Design Bureau has recently developed a guided projectile for the BMP-3 that has a maximum range of 5,500m.

Secondary armament on the BMP-3 is a 30mm rapid fire cannon and a 7.62mm machine gun. Finally, there are two 7.62mm machine guns installed, one either side at the front of the hull that cover the frontal arc.

Development of this BMP-3 upgrade is complete. It can be installed on new vehicles as they are built or retrofitted in the customer's own country.

According to the manufacturer, the Russian Army has shown a keen interest in some parts of the upgrade package, in particular the automatic gear selector.

Russia is also manufacturing other upgrades for the BMP-3, including an advanced explosive reactive armour (ERA) package fitted over the frontal arc, which provides a high level of protection against munitions fitted with a HEAT warhead.

It is understood that a local country has already purchased this package and these are being installed on its BMP-3 vehicles. Thermal sights can also be fitted to the BMP-3.

Bạn Antey đưa loại xe bọc thép M2A3 and M3A3 Bradley Fighting Vehicle Systems (BFVS) của Mỹ là loại ghê gớm đã sử dụng cùng tăng Abram tại vùng vịnh và kết quả khá do dùng tên lửa chống tăng-loại này có thể dùng cả 3 loại tên lửa TOW , Dragon ,Javelin trong đó TOW bắn gần 4 km nay chắc đã có nhiều cải tiến, gồm có
-M2 Infantry Fighting Vehicle [IFV]
-M3 Cavalry Fighting Vehicle [CFV]
-Loại A2 là đời cũ, loại A3 là loại cải tiến.
Mỹ dùng loại này cho thuỷ quân lục chiến -để độ bộ nhiều.
M2A3 and M3A3 Bradley Fighting Vehicle Systems (BFVS)

The mission of the Bradley Fighting Vehicle [BFV] is to provide mobile protected transport of an infantry squad to critical points on the battlefield and to perform cavalry scout missions. The BFVS will also provide overwatching fires to support dismounted infantry and to suppress or defeat enemy tanks and other fighting vehicles. The Bradley Fighting Vehicle is a fully armored, fully tracked vehicle designed to carry Mechanized Infantry into close contact with the enemy. It possesses sufficient cross-country mobility to keep up with the Abrams Main Battle Tank, medium and long-range firepower capable of defeating any vehicle on the battlefield, and is adequately armored to protect the crew from artillery and small arms threats. During World War II, the vehicle's namesake, General Omar Bradley, was known as the "GI General".
The Bradley is able to close with and destroy enemy forces in support of mounted and dismounted Infantry and Cavalry combat operations. The Bradley Fighting Vehicle family currently consists of two vehicles: the M2 Infantry Fighting Vehicle and the M3 Cavalry Fighting Vehicle. Just as with its predecessor, the M113 family, the Bradley will eventually be the platform for a wide range of support vehicles.
Unlike the M113 family of vehicles the Bradley replaces, this is not simply a "battle taxi". The Bradley is a sophisticated weapons platform capable of providing tremendous firepower in direct support of the Infantry it carries. The role of the Bradley is to
? Safely transport Infantry to critical locations on the battlefield;
? Provide fire support to cover their dismounted operations, and
? Destroy enemy tanks and other vehicles that may threaten the Infantry it carries
The Bradley?Ts main armament is the M242 25mm "Bushmaster" Chain Gun, manufactured by McDonnell Douglas. The M242 has a single barrel with an integrated dual-feed mechanism and remote ammunition selection. Either armor piercing (AP) or high explosive (HE) ammunition may be selected with the flick of a switch. The Gunner may select from single or multiple shot modes. The standard rate of fire is 200 rounds per minute, and has a range of 2,000 meters (depending on the ammunition used). A wide range of ammunition has been developed for this weapon, making it capable of defeating the majority of armored vehicles it is likely to encounter, up to and including some main battle tanks. The M240C machine gun, mounted to right of the Bushmaster, fires 7.62mm rounds.
When facing heavier enemy armor the Bradley relies on the TOW Anti-Tank Missile, manufactured by the Hughes Aircraft. Launched from a smooth tube launcher, the missile?Ts wings and tail fins are folded inside its body until launch. Two of these missiles are carried ready to fire in a collapsible, armored launch rack on the left of the turret. The Bradley must stop in order to fire these missiles, which are them reloaded by the Infantrymen in the back of the vehicle, using a special hatch which provides armor protection during the reload operation. The missile is equipped with a massive shaped charge, high explosive warhead and is propelled by a two-stage solid propellant motor. The range of the TOW missile is nearly 4 kilometers and the missile will reach a speed of almost Mach 1 on its way to the target. This weapon is capable of destroying any armored vehicle in existence today and is deadly accurate.
The wide tracks and 600 horsepower turbo-diesel power plant give the vehicle the mobility it needs to keep up with the Abrams, and keep the soldiers it carries out of harms way. In order to fulfil the requirement for rapid worldwide deployability, the Bradley can be transported by truck, rail, ship and transporter aircraft. In addition, all Bradleys are amphibious. Early models were equipped with a water barrier, which is erected by the crew before entering the water ?" a procedure that takes about 30 minutes. Later models have an inflatable pontoon, which fits on the front and sides of the vehicle. This pontoon is inflated in about 15 minutes, and is continuously pressurized during operation. The pontoon is compartmentalized to provide protection against sinking in the event of rupture of the pontoon. Water propulsion is provided by tracks which propel the vehicle at about 4 MPH.
The vehicle's reliability, survivability and lethality has surpassed initial expectations. Of the 2,200 Bradleys involved in Operation Desert Storm, only three were disabled. In fact, more enemy armored vehicles were destroyed by Bradleys than by the Abrams Main Battle Tanks!
The M2 Infantry Fighting Vehicle [IFV] is a fully tracked, lightly armored vehicle that offers significant improvements over the M113 series of armored personnel carriers. The M2 possesses greater power, greater acceleration, and an advanced suspension for a significant increase in cross-country speed. Like the M113, the primary purpose of the M2 is to carry infantryman on the battlefield, and transport and support them with fire if necessary. The M2 Bradley carries a crew of three (Commander, Gunner & Driver) and a six-man Infantry section into combat.
The M3 Cavalry Fighting Vehicle [CFV] is exactly the same chassis as the M2 IFV with some minor internal differences. The M3 is a cavalry/scout vehicle, instead of carrying 6 dismounts in the payload compartment, the M3 carries a pair of scouts, additional radios, ammunition, and TOW and Dragon or Javelin missile rounds. In fact, the only noticeable differences between the M2 and the M3 are that the external firing ports for the squad M16s are absent on the M3.
By the end of 1994 the Army had produced a total of 6,724 Bradleys, 4,641 in the M2 Infantry configuration and 2,083 in the M3 Cavalry configuration. Three versions of the M2/M3 have been procured: 2,300 "basic," or A0 Bradleys; 1,371 A1 Bradleys which incorporates the TOW 2 missile subsystem; and 3,053 A2 "high survivability" vehicles. Currently, the Army is conducting depot conversion of A0 and A1 Bradleys to the A2 configuration, modifying 1,423 A2s to the A2 ODS configuration, and preparing to upgrade 1,602 A2s to the A3 configuration. M2/3A0s and A1s will continue to be upgraded to the A2 configuration in FY96. Selected M2/3A2s will be modified with the ODS upgrade pachage through FY02. The First Unit Equipped (FUE) for the A2 ODS variant was FY96. The M2/3A3 vehicle configuration is in EMD with FUE scheduled for FY00.
The M2A3 and M3A3 Bradley Fighting Vehicle Systems (BFVS) are improved versions of the M2A2 and M3A2 BFVS. The BFVS-A3 includes enhancements intended to improve lethality, mobility, survivability, and sustainability. Additionally, these enhancements are intended to provide increased situational awareness and digital command and control capabilities necessary to provide information superiority to the dominant maneuver force. The Bradley Fighting vehicle and the Abrams Tank are the two central components of the dominant maneuver digital force.
The M2A3/M3A3 model of the Bradley will facilitate enhanced command and control, greater lethality, and provide mobile protected transport of an Infantry squad, and Cavalry crewmen to critical points on the battlefield. M2A3/M3A3 will facilitate mechanized Infantry, cavalry scout, and other claimant (Bradley equipped Fire Support and Stinger Teams) missions in the 21st Century. Upgrades include advanced technology in the areas of command and control, lethality, survivability, mobility, and sustainability required to defeat current and future threat forces while remaining operationally compatible with the Abrams main battle tank. The M2A3/M3A3 will provide overwatching fires to support the dismounted infantry and suppress/defeat enemy tanks, reconnaissance vehicles, IFVs, armored personnel carriers, bunkers, and attack helicopters. In the Cavalry role, it will be used to conduct reconnaissance operations, economy of force, and screening missions. It will be employed in Combined Arms units alongside the M1A1 D and M1A2 SEP tank.
A3 Upgrade
The A3 upgrade to the Army?Ts Bradley fighting vehicle system is a major component of the Army digitization initiative, designed both to complement the capabilities provided by the M1A2 SEP and to incorporate needed enhancements identified during the Gulf War. The M2A3/M3A3 will be equipped with a digital electronic architecture incorporating on-board subsystem monitoring, diagnostics/ prognostics, and an Army Technical Architecture (ATA) compliant Command and Control software suite that is fully interoperable with M1A2 SEP and M1A1 D tanks, and other Force XXI digitized platforms. When equipped with upgraded Bradleys, mechanized infantry units will be able to share battlefield data with M1A2 SEP-equipped armor units. The digitization upgrades will improve both situational awareness and sustainability through automated fault reporting and diagnostics. The A3 upgrade will also increase the lethality of the Bradley by adding an improved fire control system and a commander?Ts independent thermal viewer.
Increased funding for Stryker and Future Combat Systems (FCS) came as a result of Army decisions in 2002 to terminate or restructure some 48 systems in the FY ?~04-?T09 Program Objective Memorandum (POM) long-term spending plan. Among the systems terminated were: United Defense?Ts Crusader self-propelled howitzer and the A3 upgrade for the Bradley Fighting vehicle, GD?Ts M1A2 Abrams System Enhancement Program, Lockheed Martin?Ts Army Tactical Missile System Block II and the associated pre-planned product improvement version of Northrop Grumman?Ts Brilliant Anti-armor (BAT) munition, Raytheon?Ts Stinger missile and Improved Target Acquisition System, and Textron?Ts Wide Area Mine.
BFVS-A3 enhancements include
? a vehicle control and operation system to control and automate many crew functions and to enhance situational awareness by transmitting, receiving, storing, and displaying digital messages. This digital capability is to be compatible with all components of the combined arms team.
? the improved Bradley acquisition system (IBAS) and commander's independent viewer, both 2nd generation FLIR's, to improve target acquisition and target engagement.
? a position navigation system with GPS receiver to enhance situational awareness.
Most of the modifications to the Bradley take place inside the vehicle and its turret. Although the turret of the A3 is smaller than the A2's, additional components and software to be installed increase the A3's ability to "shoot, move, and communicate". Moreover, functional improvements are to be made to the A3's electrical power system, Nuclear Biological Chemical protection system, 25mm enhanced gun system, situational awareness capability and its navigational systems.
Electrical power to the A3 is segregated such that many of the components in the A3 can continue to operate despite the failure of other components. Power will be supplied by a 400-ampere voltage and current-regulated generator connected to six hull batteries and one 24-volt turret battery.
The 25mm enhanced gun system will have two types of barrels, nitride and chrome. The gun uses the chrome-lined barrel to compensate for the higher temperatures when firing the new depleted uranium penetrator and other service ammunition. Removable link bridge plates will be installed on the feeder, replacing the old permanent bridge plates to ease the removal of jams and aid in cleaning out debris and/or dust build-up. Also, the manual safe switch will now travel approximately 30 percent beyond center when placed in the fire position to prevent the switch from jumping back to the safe mode when firing a weapon.
The upgrade will also touch on the troop compartment which will be reconfigured to accommodate 10 soldiers, consisting of a three-man crew and seven dismounts. The dismount squad leader will have his own display screen in the back of the A3 so that he and his dismounts can see what the Bradley commander (BC) and gunner see through their sights. The BC will also have the added advantage of a "target designator" enabling him to bring his gunner's line of sight or view of the battlefield online with his own at the push of a button. This way if the BC sees something on the battlefield in another area, the BC can change his gunner's sight picture instantly.
The A3's on-board diagnostics capability will enable it to execute a system-level built-in test on power up and continually monitors system status while power is applied. Malfunctions are to be displayed on the commander's tactical display to alert the crew of potentially dangerous faults. Pre-mission and preventive maintenance checks and services are built into software to make it easier for the operator to maintain the system. In the event of a failure which the crew cannot correct, maintenance personnel will no longer have to lug around six boxes of test equipment and a series of more than 13 technical manuals in order to troubleshoot the vehicle. The vehicle diagnostic and maintenance software will provide embedded diagnostic and maintenance capability.
Improvements to the sights will be combined with the advent of the squad leader's display, voice and data radios, digital maps, alerts, malfunctions, and digital messaging. Other improvements include a larger gas particulate filter system, along with additional crew stations and heaters, to provide NBC protection for the entire crew, both mounted and dismounted.
Approximately 1,602 Bradley A2s will be remanufactured into A3s, including fire support and air defense derivatives. Engineering and manufacturing development of the A3 upgrade will continue through FY 1999. In March 1994, the Army awarded a contract to United Defense, Limited Partnership, to begin the engineering and manufacturing development phase. In June 1997, the Army approved the first LRIP for 35 systems with an FY98 option for an additional 18 systems, and low-rate production began in July 1997. A subsequent LRIP decision is scheduled for FY99 for 78 systems. The IOT&E for the BFVS-A3 is scheduled for 3/4QFY99. This IOT&E will be conducted in conjunction with the FOT&E 3 for the M1A2 Abrams System Enhancement Program. The LFT&E is scheduled for 3QFY98 through 1QFY99. The full rate production milestone decision is scheduled for 1QFY00.
The hull of the Bradley is constructed of welded aluminum and supplemented at critical locations by spaced laminate armor. The latest version of the Bradley, the M2A2, has additional applique steel armor to help defeat ballistic ammunition, with provision for explosive reactive armor for increased protection against shaped charge weapons. The Applique armor tile system is designed to increase the survivability of the Bradley Fighting Vehicle System (BFVS) against shaped-charge threats using reactive armor technology. Information regarding the specific mechanism of operation and threat level is classified SECRET. A Bradley vehicle set of armor tiles consists of 105 tiles in the following quantities: 26 M3A1, 9 M4A1, 55 M5A,1 7 M6A1, and 8 M7A1. The armor tiles were subjected to comprehensive technical testing and evaluation during Phase II (screening tests) and Phase III (performance specification qualification tests). The coordinated test plan for this evaluation was formulated by AMSAA, TECOM, CSTA, PM - Bradley, and ARDEC. The testing has demonstrated the tiles are safe and meet the performance requirements.

Russia - BMP-3M begins trials

Nikolai Vovichkov
The Tula-based KBP Instrument Design Bureau has now completed engineering work and begun testing an upgraded BMP-3 infantry fighting vehicle fitted with the company's new turret. The new model is initially designated BMP-3M (M for 'modernised'), but if launched into series production it will become the BMP-4. KPB is reponsible for the new turret, while the Kurganmashzavod Joint Stock Company builds the chassis. The upgrade will allow the BMP-3 to engage tanks as well as soft-skinned vehicles and dismounted infantry on the battlefield (see JDU Vol VI no.3 pp7-8).
KBP claims that the new turret package considerably enhances the efficiency of the BMP-3 in its existing combat roles, and offers previously unavailable capabilities. Among these capabilities are: firing all types of armament at night; automatic target tracking and effective engagement of airborne targets; and firing from enclosed positions.
The new turret used on the BMP-3M was originally shown at the IDEX 2001 exhibition in Abu Dhabi, fitted on a BTR-90 8x8 armoured personnel carrier, and it is anticipated that it has application to other combat vehicles, including the BMP-2 and BMD-3. The BMP-3M is planned to be displayed at the IDEX 2003 exhibition, although at this stage it is unknown if it will participate in demonstration firings.
Russia starts tests of upgraded BMP-3M

Russia's Tula-based Instrument Design Bureau (KBP) has finished engineering work and started testing an upgraded BMP-3 infantry fighting vehicle (IFV) fitted with the company's new turret. The vehicle has been given the preliminary designation of BMP-3M (M for 'modernised') but if launched into series production it will be designated the BMP-4. KBP is responsible for the BMP-3's turret, while the Kurgan Machine Construction Plant builds the chassis.
KBP is proposing three upgrade packages for the vehiclê?Ts turret. The first is essentially an ammunition upgrade comprising a new 100mm gun-launched laser-guided projectile, a new 100mm high-explosive fragmentation round, a new 30mm armour-piercing discarding sabot round and a new digital computer.
The second package includes the ammunition elements plus a fire-control system (FCS) upgrade with a new integrated gunner's sight and a new weapon stabilisation system.
The third option comprises a new turret that retains the original weapons fit but provides a high-resolution automatic FCS, new ammunition reserve and a single reloading system. The turret also provides additional armour protection. This turret was shown for the first time at the IDEX 2001 exhibition in Abu Dhabi installed on a modified BTR-90 series 8 x 8 armoured personnel carrier (Jane's Defence Weekly 4 April 2001).
The Russian Army is now evaluating the BMP-3M. Last month, demonstrations of the vehicle were conducted in the United Arab Emirates (UAE). The UAE has 391 BMP-3s that were delivered from 1992 to 1997 and Kuwait has 118 vehicles delivered in 1995-96. Anticipating regional interest, KBP plans to display the BMP-3 at the IDEX 2003 exhibition in Abu Dhabi
The BMP-3M is an improved version of the BMP-3, equiped with a new gunners sight, a thermal sight, KBM-3M air-conditioning system and 660hp UTD-32 engine. Optional equipment include the active protection system Arena and additional (reactive) armour.




BTR-90 (8 x 8) APC fitted with KBP turret armed with 100mm gun, 30mm cannon and 7.62mm co-axial machine gun









BTR-90







More firepower for BTR-90
By Christopher F Foss
Being shown for the first time at IDEX is a BTR-90 (8 x 8) amphibious armoured personnel carrier fitted with a new two-person advanced turret developed by the KBP Instrument Design Bureau. The vehicle is normally fitted with a BMP-2 type turret armed with a 30mm cannon, 7.62mm machine gun and roof-mounted anti-tank guided weapon (ATGW).

The new turret is of all-welded construction with an additional layer of spaced armour over the frontal arc for a higher level of protection. Its main armament comprises a 100mm rifled gun that can fire conventional natures of ammunition, for example high explosive fragmentation (HE-FRAG) or a laser-guided ATGW out to a maximum range of 5,500m. The ATGW can be fitted with various types of warheads, including one fitted with a tandem HEAT (High Explosive Anti-Tank) warhead, which will enable targets to be engaged and defeated fitted with explosive reactive armour.
While the armament and overall layout of the turret are similar to that fitted to the BMP-3 infantry combat vehicle, which is used in large numbers by a number of countries in the Middle East, its fire control and sighting system is brand new.
The commander has a roof-mounted stabilised panoramic sight with day/TV channels and a laser rangefinder, while the gunner has a day sight, thermal channel and a laser rangefinder. This system enables targets to be engaged under day and night conditions with a high first round hit probability. In a typical target engagement the target would first be detected by the commander and then handed over to the gunner who would carry out the actual target engagement.
Although shown fitted on a BTR-90 (8 x 8) APC, the new turret can be installed on a wide range of other chassis, tracked and wheeled.
The BTR-90, which has been built in small quantities, is essentially a much enlarged BTR-80. This in turn was a development of the earlier BTR-70 and BTR-60 (8 x 8) vehicles, which have been built in large numbers for the home and export markets. The BTR-90 has a crew of three - commander, gunner and driver - and can carry seven fully equipped infantry, who can rapidly dismount via hatches in either side of the hull.
Standard equipment includes powered steering on the front axles, a central tyre pressure regulation system and an NBC system. The vehicle is fully amphibious, being propelled in the water at a speed of 9km/h, with a maximum road speed of 91km/h and a maximum range of 700km.
