Tank Ex, or Karna Tank, was the code name of the prototype main battle tank developed by the Defence Research and Development Organisation (DRDO) in 2002. Tank ex is based on existing Arjun and Ajeya tank. This MBT uses turret and weapon system's of the Arjun MBT and chassis of the T-72 M1 (Ajeya) MBT. [1] Tank Ex was developed as an attempt to modernize India's existing Ajeya tanks, using technology derived from the development of the Arjun MBT. [2] It was named after Karna , the chief protagonist of the Indian epic The Mahabharata . [3] [1] [4] It underwent six months of trials, but was subsequently rejected by the Indian Army. Total eight Tank Ex prototypes were built. [1]
The Tank Ex MBT uses the chassis of the T-72M1 (Ajeya) and turret and weapon system of the Arjun. It was developed in 2002 as a private venture and was intended to provide a solution for upgrading the Indian Army's ageing T-72M1 fleet. It was rejected by the Indian Army after eight prototypes and six months of trials. [1]
On July 5, 2008, Gen. Dalip Bhardwaj, the Indian Army's Director General of Mechanized forces (DGMF), declared that the army had rejected Tank Ex. This was part of an announcement that there would be no further orders for Arjun tanks, and that the military would be inviting participants from various countries to discuss future tank developments. [5]
Weighing in at 47 tons, the Tank Ex is heavier than the T-72M1 (41 tons) and much lighter than the Arjun MBT, (58.4 tons). It has a 1,000 hp (700 kW) power plant giving a power-to-weight ratio of 21 hp (16 kW)/ton for a total weight of 47 tons. This represents an improvement over the T-72M1's 20 hp (15 kW)/ton, with a weight of 41 tons and a 780 hp (582 kW) power plant. The Tank Ex utilizes the Arjun MBT's 120 mm rifled gun firing unitary APFSDS and HESH semi combustible cartridge case ammunition. [1] [2] A total of 32 rounds are carried, as compared with 39 in the Arjun and 45 two piece rounds in the T-72. [2] A global positioning system is provided for accurate navigation. [2] This is a feature common to both the Arjun MBT and the Combat Improved Ajeya.
The Tank Ex utilizes the "Kanchan" composite armour, especially over its frontal arc (turret as well as glacis), giving it protection against both Kinetic and HEAT rounds. [1] [2] The usage of the Arjun turret design indicates that the Tank Ex may also have its "ready" ammunition stored in the bustle (as in the Arjun), separated from the crew and provided with blow-off panels. This would be a significant protective feature comparable with Western design practices. The Tank Ex retains the T-72's mobility, with a road speed of 60 km/h [1] and a cross-country speed of 40 km/h. [2] [6] With a maximum gradient climb of 30 degrees, it remains in line with all variants of the T-72, like the T-72BM. The Tank Ex is better at trench crossing with a capability of crossing 2.6 meters as compared to the T-72M1's 2.28 metres. The Tank Ex can also climb vertical obstacles up to 0.85 metres tall. The tank's shallow fording capabilities are quoted as 1.2 metres. The Tank Ex should also have the capability to fire the Israeli LAHAT missile from its gun-barrel, like the Arjun. [1]
The MBT-70 was an American–West German joint project to develop a new main battle tank during the 1960s.
The T-90 is a third-generation Russian main battle tank developed from, and designed to replace the T-72. It uses a 125 mm 2A46 smoothbore main gun, the 1A45T fire-control system, an upgraded engine, and gunner's thermal sight. Standard protective measures include a blend of steel and composite armour, smoke grenade dischargers, Kontakt-5 explosive reactive armour (ERA) and the Shtora infrared anti-tank guided missile (ATGM) jamming system.
The T-84 is a Ukrainian main battle tank (MBT), based on the Soviet T-80 MBT introduced in 1976, specifically the diesel engine version: T-80UD. The T-84 was first built in 1994 and entered service in the Ukrainian Armed Forces in 1999. Its high-performance opposed-piston engine makes it a fast tank, comparable to other modern MBTs with a power-to-weight ratio of about 26 horsepower per tonne.
The Arjun is a third generation main battle tank developed by the Combat Vehicles Research and Development Establishment (CVRDE) of the Defence Research and Development Organisation (DRDO), for the Indian Army. The tank is named after Arjuna, the archer prince who is the main protagonist of the Indian epic poem Mahabharata. Design work began in 1986 and was finished in 1996. The Arjun main battle tank entered service with the Indian Army in 2004. The 43rd Armoured Regiment, formed in 2009, was the first regiment to receive the Arjun.
The PT-91 Twardy is a Polish main battle tank. A development of the T-72M1, it entered service in 1995. The PT-91 was designed at the OBRUM and is produced by the Bumar Łabędy company, part of the Bumar Group, a Polish technical military consortium. Changes from the T-72M include a new dual-axis stabilized fire-control system, reactive armour, a more powerful engine, transmission and new automatic loader.
The C1 Ariete is a 3rd generation main battle tank of the Italian Army, developed by Consorzio Iveco Oto Melara (CIO), a consortium formed by IVECO and OTO Melara. The chassis and engine were produced by Iveco, while the turret and fire-control system were supplied by OTO Melara. The vehicle carries the latest optical and digital-imaging and fire-control systems, enabling it to fight day and night and to fire on the move. Six prototypes were developed by 1988, which were subject to intensive testing. The following year the vehicles travelled a combined 16,000 km. Deliveries were first planned for 1993, and took place in 1994 due to delays. Final delivery occurred 7 years later in August 2002.
The FV4201 Chieftain was the main battle tank (MBT) of the United Kingdom from the 1960s into 1990s. When introduced, it was among the most heavily armed MBTs of the era, mounting a 120 mm Royal Ordnance L11 gun, the equal of the much larger specialist heavy tanks then in service. It also was among the most heavily armoured, with up to 195 mm (7.7 in) that was highly sloped to offer 388 mm (15.3 in) thickness along the line of sight.
The Type 99 or ZTZ-99 is a Chinese third generation main battle tank (MBT). The vehicle was a replacement for the aging Type 88 introduced in the late 1980s. The Type 99 MBT was China's first mass-produced third-generation main battle tank. Combining modular composite armour and tandem-charge defeating ERA, 125 mm smoothbore gun with ATGM-capability, high mobility, digital systems and optics, the Type 99 represents a shift towards rapid modernization by the PLA.
The M-84 is a Yugoslav main battle tank based on the Soviet T-72. It is still in service with Bosnia and Herzegovina, Croatia, Serbia, Slovenia and Kuwait.
The Al-Khalid/VT-1A is a main battle tank family developed jointly by Norinco of China and Heavy Industries Taxila of Pakistan. The tank is based on the Type 90-II tank. Around 310 Al-Khalid MBTs had been produced by 2014. The tank has been exported to Bangladesh, Morocco and Myanmar by China. The VT-1A is also known as MBT-2000.
An armoured vehicle-launched bridge (AVLB) is a combat support vehicle, sometimes regarded as a subtype of military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines, when a river too deep for vehicles to wade through is reached, and no bridge is conveniently located, or sufficiently sturdy, a substantial concern when moving 60-ton tanks.
The Type 80 and the Type 88 are a family of Chinese second-generation main battle tanks (MBTs). They are also known as the ZTZ80 and ZTZ88.
The AMX-40 was a French main battle tank developed by GIAT during the latter stages of the Cold War as an export tank to replace the earlier AMX-32. Designed to be an inexpensive tank orientated towards militaries with smaller defence budgets, the AMX-40 featured a lightly armoured hull and good mobility reminiscent of previous French MBTs with a powerful 120 mm cannon. It however failed to attract interest and sales, rendering the project a failure, being discontinued in 1990.

Abhay was an Infantry Combat Vehicle created under a tech-demonstration program started in India by the Defence Research and Development Organisation or DRDO. As its first IFV project, Abhay was designed to provide experience in the construction of AFV components to DRDO, serve as a replacement to India's vast BMP fleet used in its Mechanised Infantry Regiments, and serve as a test bed for weapons and systems to be used on future vehicles, as well as to be a reference for the designs of future vehicles.
The T-72 is a Soviet-designed main battle tank that entered production in 1971. It replaced the T-54/55 series as the workhorse of Soviet tank forces. In front-line Russian service, T-72s are being upgraded or augmented by the T-90, itself a modernized version of the T-72B. The T-72 has been exported and produced in many countries.
The Bhim self-propelled howitzer was a type of self-propelled artillery developed by the South African company Denel under the supervision of the Indian Defence Research and Development Organisation. It was designed to meet the Indian Army's requirements for self-propelled artillery units. The howitzer is named after Bhima, one of the main protagonists and brother to Arjun of the Indian epic "Mahabharata".
The post–Cold War era is the period in world history from the collapse of the Soviet Union on December 27, 1991 to the present. During the Cold War, the Soviet domination of the Warsaw Pact led to effective standardization on a few tank designs. In comparison, France, Germany, the United States, and the United Kingdom had previously developed their own tank designs, but now tried to standardize their designs, while the smaller nations of NATO purchased or adapted these designs.
