The designations Al-Khalid and MBT-2000 refer to the Pakistani and Chinese variants of a modern main battle tank developed during the 1990s by China and Pakistan. The Al-Khalid has been in service with the Pakistan Army since 2001, while the MBT-2000 is built and marketed internationally by China and was recently trialed by the Peruvian Army for possible acquisition.

Operated by a crew of three and armed with a 125 mm smooth-bore tank gun that is reloaded automatically, the tank uses a modern fire-control system integrated with night-fighting equipment and is capable of firing many types of anti-tank rounds as well as guided anti-tank missiles. Al-Khalid is named after the legendary Muslim general Khalid bin al-Walid.

An evolution of Chinese and Soviet tanks, the design is considerably smaller and lighter than most Western main battle tanks. It is based on the Chinese Type 90-II, which combined technologies from several Soviet/western tanks. The Al-Khalid is unusual in that it is was designed to be adaptable for manufacture, so that it can be easily integrated with a variety of foreign engines and transmissions. The current production variant of Al-Khalid utilises a diesel engine supplied by the KMDB design bureau of Ukraine. The first production models entered service with the Pakistan Army in 2001 and there are plans to induct approximately 600 in total.

Peru leased five VT-1A from China for trials in 2009. The Peruvian government has expressed interest in purchasing 80-120 units to complement the fleet of Soviet T-55 tanks in service with the Peruvian Army.^[5]

Development

In the 1970s, the leadership of China's People's Liberation Army was concerned about the Soviet threat and requested an improved main battle tank (MBT) to replace the old, obsolete Type 59. The existing Chinese tanks were direct descendants of the Soviet T-54A and were out-classed by more advanced Soviet models like the T-62 and T-64. Norinco and the Inner Mongolia First Machine Group Corporation were tasked to develop a series of new tanks.

After examining samples of T-72 tanks delivered by Iran in the late 1980s (captured from the Iraqi Army), the Chinese military realized contemporary Chinese tanks were still vulnerable. Design features of the T-72 and some western tanks were used to develop a second generation of Chinese tanks, eventually incorporating a redesigned hull and suspension, a new welded turret and 125 mm autoloaded tank gun. The Type 80 and Type 85 tanks led to the Type 90. The Type 90 was rejected for Chinese service in favour of other designs, but it influenced further development which would lead to China's third-generation Type 98 and Type 99 tanks.

The Type 90 is an evolutionary design: the Type 90-II version shares 10% of its components with the Type 59, 15% with Type 69, 20% with Type 85/88C, and is built with 55% new components. This model was put up for sale on the international market.

A development deal was signed with Pakistan in January 1990.^[6] Initial Chinese-built prototypes were tested in Pakistan in August 1991. Pakistan spent more than US$20 million over the next ten years on the co-development of a model suitable for their needs and on creating a capability to manufacture it locally. Lt Gen Hamid Javed as Director General of Heavy Industries Taxila (HIT) and Brigadier (now Major General) Mohammad Asaad supervised the project. The design team modified the tank to accept a foreign-built power pack (engine). A number of different prototypes were evaluated.

In light of high ambient temperatures and fine sand/dust that would be encountered in operational areas such as the deserts of southern Pakistan, development of high performance cooling and air filtering systems was emphasised during the planning stage of the project. Implementation of a hydro-gas suspension system was considered but, after detailed technical evaluations, it was found to be impractical due to various limitations such as problems with reliability and maintainability. Installation of the Renk 304 transmission was also considered but disregarded.^[7]

An early version was armed with a Chinese gun and fire-control system, but had a German-designed MTU-396 diesel engine which was built under licence in China. Another version was equipped with a more advanced western digital fire-control system and powered by a Perkins 1,200 hp (890 kW) Condor diesel engine (as in the British Challenger) and SESM ESM500 automatic transmission (as in the French Leclerc). This version was considered too expensive and under-performing in the extreme heat of southern Pakistan. Finally, a version was tested with the compact Ukrainian 6TD-2 1,200 hp diesel engine (Ukraine also supplied Pakistan with T-80UD tanks, powered by a similar engine). This configuration was chosen for the production version of the tank and came to be known as Al-Khalid.

Yet another version—employing more western technology had been envisaged as an export product for Pakistan. The prototype had a 1,200 hp (890 kW) German MTU-871/TCM AVDS-1790 diesel engine and an LSG-3000 transmission. But this concept was abandoned due to the arms embargo imposed on Pakistan after the 1998 Pakistani nuclear tests.^[8]

The Type 90-II was the basis for MBT-2000, which later became the Pakistani Al-Khalid and the Chinese VT-1A.

The final tank design resulting from a decade of co-operative development was designated Type 90-IIM. Chinese company Norinco showed the new Type 90-IIM during the March 2001 Abu Dhabi Defense Expo, under the export name MBT 2000. The version powered by the Ukrainian engine, intended for domestic production in Pakistan, was named Al-Khalid.

During the development period, Heavy Industries Taxila gained experience building the Chinese Type 85-IIAP and prepared to begin production of the Al-Khalid tank in 1999. A pilot batch of fifteen tanks was inducted into the 31st Cavalry Regiment of Pakistan’s Armoured Corps on 20 July 2001. Pakistan signed a contract with Ukraine's Malyshev Factory in May 2002 for the delivery of 315 KMDB 6TD-2 diesel engines over three years.^[9] An additional batch of Al-Khalid tanks was delivered on 23 September 2004. Pakistan plans to build a total of 600 Al-Khalid MBTs for its armed forces.^[10]

In 2006 a U.S.-based market/special research organisation reported findings showing that the Al-Khalid, along with two other MBTs, would account for nearly 45% of all new MBTs built until 2015.^[11]

In April 2002 it was reported that Malaysia was considering purchasing the Al-Khalid after evaluation by Malaysian military personnel.^[12]

The Saudi Arabian Army began conducting trials of the Al-Khalid's desert performance in April 2006, after expressing interest in purchasing a batch of the tank 2 years earlier. No order for the tank was placed.^[13][14]

During the first week of May 2008, Lt-Gen Fonseka of the Sri Lanka Army held talks with his Pakistan Army counter-parts regarding the sale of military equipment, weapons and ammunition. The sale of 22 Al-Khalid MBTs to the Sri Lanka Army was finalised during these talks in a deal worth over US$100 million. However the current status of this purchase is unclear as Sri Lanka has subsequently cancelled some orders for military equipment.^[15]

Design

Armament

Al-Khalid is designed with a 125 mm (length: 48 calibers) smoothbore, auto-frettaged and chrome-plated gun barrel which can fire the following types of conventional ammunition: APFSDS, HEAT-FS and HE-FS. Unlike a common belief that the gun is Chinese, it was later changed to a modified variant of KBA-3 series of 125 mm smooth bore gun for Al-khalid mbt which provided compatibility with Ukrainian ATGMs such as Kombat. Gun-launched, laser-guided anti-tank guided missiles can also be launched and two types are believed to be in use on the Al-Khalid, the Russian-designed 9M119 Refleks (AT-11 Sniper produced in China under licence and the Ukrainian-designed Kombat,^[16] which may have been modified in Pakistan to incorporate a larger warhead.^[17]

Al-Khalid also fires a Pakistani DU round, the Naiza 125 mm DU round (armor penetration: 550 mm in RHA at 2 km).^[18] Al-Khalid is equipped with a muzzle reference system and dual-axis stabilization system. Elevation and azimuth control is achieved by electro-hydraulic power drives. The automatic ammunition-handling system for the main gun has a 24-round ready-to-fire magazine and can load and fire at a rate of eight rounds per minute.^[19]

The tank is also equipped with a 7.62 mm-coaxial machine gun, a 12.7 mm externally-mounted air-defence machine gun that can be aimed/fired from within the tank and smoke grenade launchers.

The gunner is provided with a dual magnification day sight and the commander with a panoramic sight for all-around independent surveillance. Both sights are dual-axis image stabilized and have independent laser range-finders. The commander has the ability to acquire a target independently while the gunner is engaging another one thus giving it true hunter-killer capability. The automatic target-tracking system is designed to work when tank and target are both moving. Night vision for the gunner and commander is achieved through a dual-magnification thermal imaging sight. Both sights are integrated with the fire-control system.^[19] The production Al-Khalid tank has a fire-control system of western origin. In the MBT 2000, the Chinese Norinco fire-control system has inputs from ten sensors. The ballistic computation time is less than one second. The manufacturer claims routine first round hits on standard 8 ft (2.4 m) square targets at ranges over 2,000 meters.

• Effective range: 200 m to 7,000 m
• Sensor: laser ranging from 200 m to 9,990 m
• French Auto-tracking, interfaced with gunner station, firing four types of munitions, gunner's thermal imaging sight, commander's image intensification night vision sight, gyro-stabilized and UPS power supply system.

Although prototypes were demonstrated with various fire-control systems of Chinese and western origin, the production model Al-Khalid MBTs use a Western fire-control system (FCS) and gun control system (GCS).^[7]

The tank is equipped with the "Integrated Battlefield Management System" (IBMS), named 'Rehbar', a digital communications system developed domestically by HIT and CARE (Centre for Advanced Research in Engineering). ^[20] It comprises a flat-screen display mounted inside the tank which communicates with those of other vehicles, including command posts such as the HIT Sakb. It uses a data-link to facilitate secure communication of battlefield information between units, including tank video footage and information from unmanned aerial vehicles (UAV).^[17]

Mobility

The production model Al-Khalid is powered by a 6TD-2 liquid-cooled diesel engine, designed by the Kharkiv Morozov Design Bureau (KMDB) of Ukraine. The 6TD-2 is a supercharged 6-cylinder engine delivering 1,200 horsepower. The 2-stroke design, with the pistons arranged horizontally in an opposed piston configuration, makes the engine very compact and therefore more suitable for being fitted into relatively small vehicles such as the Al-Khalid MBT.^[21]

The 6TD-2 engine drives a French-designed hydro-mechanical automatic transmission, the SESM ESM500, also fitted to the Leclerc MBT. Capable of manual and fully automatic power-shifting, the transmission has 5 forward and 2 reverse speeds along with a braking system that incorporates carbon friction brakes and a secondary speed-retarding system. Gear shifts are controlled by a torque converter which is made more efficient by addition of an automatic lock-up clutch. There is also a mechanical back-up system for use in emergencies, able to shift 2 gears forward and reverse.

The suspension consists of torsion bars, hydraulic dampers and buffers, who's role is to provide a stable firing platform while the tank is moving at speed over rough terrain and as smooth a ride as possible to reduce crew fatigue. The tracks are mounted on six dual wheels with rubber tyres, a drive sprocket at the rear and an idler at the front. They are protected by side skirts, the forward sections of which can be fitted with explosive reactive armour, and track wear is reduced by replaceable rubber track pads.^[3]

The Al-Khalid is fairly lightweight by Western standards, weighing 46 tonnes compared to the 60 tonne M1 Abrams and Leopard 2.^[22] A power-to-weight ratio of 26.66 hp/tonne gives acceleration from 0 to 32 km/h (0 to 20 mph) in 10 seconds and a maximum speed of 70 km/h, the speed and agility also helping to improve survivability.^[3][22]

A snorkel allows the tank to cross water obstacles up to 5 meters deep, after some preparation by the crew. Navigation is assisted by an inertial navigation system (INS) and a GPS satellite navigation system.

Protection

Al-Khalid has modular composite armour and explosive reactive armour, nuclear-biological-chemical defences, an effective thermal smoke generator, internal fire extinguisher and explosion-suppression system. The infra-red signature of the tank is reduced by infra-red reflective paint.^[3] Al-Khalid 1 is equipped with a newly developed indigenous ERA which is not only light weight, but also more resistant to APFSDS, HEAT and HE-FS rounds. ERA is developed by Global Industries and Defense Solutions (GIDS) Corporation. ^[23] Al-Khalid is also equipped with an Active protection system known as VARTA (guards) which is a Ukrainian modification of Russian Shtora APS system. HIT is also working on an indigenous APS system for future batches especially for Al-Khalid 2.

An advanced laser detection system from Al Technique Corporation (ATCOP) is present, the ATCOP LTS 1 laser threat warning system developed by Institute of Industrial Control Systems.^[24] LTS 1 consists of a mast-mounted sensor and operator's control box, which includes a display showing threats 360 degrees around the tank. It can detect laser rangefinders and laser target designators as well as respond automatically by triggering acoustic alarms, smoke generators and other countermeasure systems. LTS 1 can detect laser devices operating in the 0.8 to 1.06 µm waveband, has a 360° field of view in azimuth (resolution of 15°) and a field of view in elevation of -15° to +90°. Operating voltage is 12 V or 24 V DC nominal with power consumption being 8 W nominal. The sensor head is 165 mm in diameter and 35 mm high while the control box is 80 x 130 x 55 mm in size. Laser Threat sensor LTS786P is an early warning device which gives audio and visual alarms of threat by sensing a laser beam aimed at it from any direction. The exact location of the threat (in-coming beam) is indicated by nine LEDs, covering all directions above horizon. It has the capability to differentiate between a laser Range Finder, Laser Target Designator or a Laser Target Tracker Signal. In addition, provision of sensor output signal, interfacing for appropriate counter-measures, is also available. It can be used on stationary or moving objects of any size or shape. Maximum operating Range is 10 km.
