Main Battle Tanks in 21st Century
Images of tanks leading offensive operations continue to dominate news reports from Iraq, Syria, Ukraine and other war zones over the past five years. The combination of firepower, protection and mobility that tanks bring to armies remains just as relevant today.

In June 2018, the French Defence Minister Florence Parly and her German counterpart, Ursula von der Leyen, signed letters of intent to develop a new tank, dubbed the Main Ground Combat System (MGCS). The French and German ministers agreed that the demonstration phase should begin by mid-2019 and that detailed operational requirements would be established by 2024, with Germany as the lead nation. The MGCS will be integrated into the French Scorpion programme and the German Fhrungsinformationssystem Heer (Army Command, Control and Information System, FInfoSys) with deployment of the new tank planned in 2035. The German Ministry of Defence said the system would replace the Leopard 2 in Bundeswehr service, going beyond a linear upgrade of the tank"s capabilities.

The Franco-German joint venture, KMW+Nexter Defense Systems KNDS) has already carried out preliminary work under the banner of the Euro Main Battle Tank (EMBT) demonstrator, which was put on show at the Eurosatory event in Paris on June 2018. The demonstrator tank had a German Leopard 2A7 hull, engine and chassis and a Nexter Leclerc two-man turret with an automatic loading system.

The US Army has received bids for its Mobile Protected Firepower (MPF) programme from both BAE Systems and General Dynamics Land Systems (GDLS). It is hoped that a new MPF platform can quickly deploy with relatively low logistics demand but enough protection and firepower - likely a light- to medium-tank - to ensure battlefield freedom of action.

BAE Systems submitted a written proposal in March 2018 that "leveraged the army"s earlier investment in, and made improvements on, the type-classified M8 Armored Gun System [AGS] - as well as other previous programmes - into a fully integrated MPF system".

BAE Systems said the US Army"s earlier investment in M8 Armored Gun System - as well as other previous programs - had bee fully integrated MPF system. By adding modern technology, BAE Systems said it had developed a low-risk solution that has both a mature design and the latest in innovation. It provides a highly survivable, lethal, mobile, and transportable vehicle system to US Army Infantry Brigade Combat Teams.

Opposing BAE in the competition is General Dynamics Land Systems (GDLS), who in October 2016 unveiled a medium-weight tracked vehicle demonstrator, called the Griffin, which meshes elements of the turret and the 120 mm cannon from the US Army"s M1A1/M1A2 Abrams main battle tank with the company"s Ajax Scout Specialist Vehicle.

Russia"s T-14 Armata is a next generation main battle tank based on the Armata Universal Combat Platform. It is the first wholly new series-produced next generation tank to be developed in Russia since the 1980s. The Russian Army had planned to acquire 2,300 T-14s in the period 2015-2020 but production and fiscal shortfalls meant this was pushed the date back to 2025.
The T-14 features a number of innovative developments, with the most significant novelty being a an unmanned turret, with the crew of three seated in an armoured capsule in the front of the hull.

The main armament of the T-14 is the 2A82-1M 125 mm (4.92 in) smoothbore cannon, a replacement for the 2A46 125 mm gun of previous Russian and Soviet tanks. Its muzzle energy is greater than one of the world"s best cannons - the German Leopard 2 Rheinmetall 120 mm gun. The 125 mm gun has 15-20% improved accuracy and its rolling fire angular dispersion has improved 1.7 times. Features include an absence of a fume extractor (due to the unmanned turret), a firing rate of 10-12 rounds per minute, left side casing ejection port for the 125 mm gun and a maximum effective-penetration range of 8 kilometres with anti-tank guided missiles (ATGM). The 2A82-1M 125 mm cannon can fire high-powered munitions, including armor-piercing discarding sabot projectiles, guided missiles, shaped-charges and other types of munitions.

The T-14"s crew of three is protected by an internal armoured capsule with more than 900 mm RHA equivalent, increasing their chance of survival in case of a catastrophic kill. Both the chassis and the turret are equipped with the Malachit dual-explosive reactive armour (ERA) system on the front, sides and the top. The turret"s shape is designed to reduce its radar and thermal signature. The tank uses an integrated, computerized control system which monitors the state and functions of all tank modules. In battle, the software can analyze threats and then either suggest or automatically take actions to eliminate them, while without the external threat it can detect and rectify crew errors. Serial production of the Armata Platform"s ceramic armour components began in mid-2015. Afghanit hard-kill launchers are the long tubes mounted in groups of five between the turret"s front sides and the chassis. These send out an electronically activated charge that fires an Explosively Formed Penetrator towards the target (in all directions).
