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. Bangladesh Army recently ordered 44 MBT-2000.
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 and 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.| Al-Khalid Type 90-IIM / MBT-2000 | |

Al-Khalid MBT 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. Despite 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, which may have been modified in Pakistan to incorporate a larger warhead.
Al-Khalid also fires a Pakistani DU round, the Naiza 125 mm DU round (armor penetration: 550 mm in RHA at 2 km). 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.
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. 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 to 7 000 m
- Sensor: laser ranging from 200 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).
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). 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).
A project to manufacture the first Pakistani tank gun barrel was begun by Pakistan's Strategic Plans Division (SPD), which was set up in 2000. In April 2011, it was reported that the first Pakistani-produced tank gun barrel was ready to be delivered to HIT for installation on the Al-Khalid and Al-Zarrar. Previously, HIT imported 125 mm gun barrel blanks from France for the two tanks which would then be machined in Pakistan by HIT. The first Pakistani gun barrel blank was produced at Heavy Mechanical Complex (HMC) in a joint project involving HIT, People's Steel Mills Limited (PSML) and other defence-related organizations. The specialist grade steel was produced at PSML and the resulting steel block was passed on to HMC. HMC then pressed the block to a length of 5 metres and square cross-section, before forging it into a 125 mm smoothbore barrel. The barrel was then heat treated several times in facilities such as a large vertical furnace. The process took 2–3 months and was watched by experts from other defence-related organisations. The barrel was to be capable of firing at least 8 rounds per minute as well as for compatibility with the autoloader and its 24 round magazine. According to a HIT official, a joint team proved to the Pakistan Army that strict standards would be met before the army approved production of a first batch of 50 gun barrels by HMC. The Pakistani gun barrels would likely be installed on upgraded versions of the Al-Khalid which are under development by HIT. A Rs200 million PKR contract has been finalised by HIT for the first 50 barrel batch, which is slightly lower than the barrels imported from France. After production of this first batch of tank gun barrels, HIT is planning to explore manufacture of artillery guns.
Al-Khalid MBT 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 (890 kW). 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.
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.
The Al-Khalid is fairly lightweight by Western standards, weighing 46 tonnes compared to the 60 tonne M1 Abrams and Leopard 2. 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.
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.
Al-Khalid MBT 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. 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. 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. 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.
