Posted By: Alex Hempel June 25, Courtesy of Rheinmetall. German arms manufacturer Rheinmetall recently unveiled its new highly-anticipated mm cannon design for use on next-generation tanks.
All of these mm cannons have generally similar ballistic performance and will be referred to collectively. Intended for use in next-generation main battle tanks, the new gun mm comes at a time when tank armor is becoming increasingly difficult to penetrate. This T tank is covered in older ERA bricks. It is in this context that the mm gun becomes appealing. This increase ensures that the mm gun will remain potent for some time, whereas the ability of the mm gun to counter future advances in protection is less clear.
However, it remains unseen whether or not the mm gun will eventually achieve the ubiquity of its predecessor. In fact, trials during the Cold War were undertaken with even larger mm guns.
This Abrams-based testbed is fitted with a massive mm cannon. The idea ended up being abandoned, as issues effectively integrating such a large gun into the Abrams platform arose. The mm is heavier, at 3. Housing the slightly enlarged mm, as well as its correspondingly enlarged equipment, will necessitate a redesigned turret, according to Rheinmetall engineers. At this point, it is worthwhile to examine the role of the MBT on the battlefield.
Rather, they are all-purpose armor intended to fill a variety of roles, from engaging other tanks to exploiting maneuver opportunities and bolstering infantry operations. Most obviously, there is the issue of operational mobility, or the ability of the tank to move to the battlefield under its own power.
Obviously, a higher weight per unit area results in the tank being more prone to sinkage into soft ground as well as more rapid wearing of road surfaces. If the weight of a mm-armed tank were to be increased but the track size was to remain the same, problems associated with higher ground pressure would manifest.
The larger the vehicle, the more difficult it is to fit on narrow roads, through urban streets, and over bridges. No matter the track size or ground pressure, overall weight also plays a factor: excessively heavy tanks may be unable to pass over weak bridges without risking collapse, which is problematic when there are many rivers in the area of operations.
Also important is the effect of weight on strategic mobility, which is the ability to move the tank from where it is based to where it is needed for combat.
And, of course, if there is a large body of water such as a sea or ocean, boats are a necessity. Trains and trucks have payload size limits, namely the width of roads and the maximum width of a train car as permitted by rail infrastructure.
So, in conclusion, tank designers will have to avoid significant increases in weight and size when producing new tanks with the mm cannon. Increases of more than a few tons over current-gen tanks would likely be unacceptable, and such increases could be wrought on not only by the inclusion of a new gun but also of new protective systems, drive technologies, etc.
Because the mm cannon will be heavier, other components will need to get lighter.German Army to Upgrade 104 Leopard 2 Tanks to the A7V Standard
Given past trends in tank warfare as well as the trajectory of aircraft and ship weights, this seems a tall task — tanks, planes, and indeed most vehicles have tended to become larger and heavier as time passes. Whether tank designers can halt this trend while still incorporating the larger mm gun remains to be seen.
The cartridge, which contains the shell and its propellant, is loaded into the breech of the gun the gun before it can fire. The mm cartridges are 30 kg, whereas the mm cartridges are 21 kg. Because of this significant 9 kg increase in weight, Rheinmetall engineers believe that the mm cartridges must be autoloaded.
Autoloading is the process by which mechanical means are used to reload the gun, as opposed to manual loading, in which a human loader performs the task. A Russian serviceman loads trays into a T autoloader. On paper, autoloading seems attractive.

Post to Cancel.Rheinmetall Weapons and Ammunition "has completed developmental efforts" of an initial new Next Generation NG mm smooth bore tank gun, but some further design changes are expected, company officials told Jane's. A Rheinmetall representative, who requested anonymity, said the weapon is an L51 cannon and uses new high-strength steel, is chrome plated with a vertical sliding breech mechanism, electrical firing mechanism, and an increased chamber volume so more propellant can be used to enable higher muzzle velocities and therefore greater armour penetration characteristics.
It is fitted with a thermal sleeve and muzzle reference system, according to the representative. Rheinmetall said the 6. The company representative confirmed that, by Novemberabout 80 rounds had been fired at its proving ground. The representative said the chamber of the first NG mm has a volume of 15 litres and a design pressure of MPa, but added that "due to the experiences and knowledge gained in the live firing trials, this data will be modified in the next stage of development.
The first mm round developed by Rheinmetall is an armour-piercing fin-stabilised discarding sabot - tracer APFSDS-T with a semi-combustible cartridge case, new high-energy propellant that is insensitive munition IM compliant, and a new advanced long rod tungsten penetrator for greater penetration characteristics.

This includes a series of kinetic energy penetratorssuch as the American M series, and high explosive anti-tank warhead s.
Recent ammunition includes a range of anti-personnel rounds and demolition munitions. The LAHATdeveloped in Israel, is a gun-launched missile which has received interest from Germany and other Leopard 2 users, and is designed to defeat both land armour and combat helicopters.
The Israelis also introduced a new anti-personnel munition which limits collateral damage by controlling the fragmentation of the projectile. Because of concerns about the inability of the millimeter 4. A project started inas the Bundeswehr felt a more powerful gun was needed for its new tanks. The new tank carried a three-man crew, with the driver in the turret, an automatic loader for the main gun, a millimeter 0.
Although there were attempts to modify the millimeter 6. Krauss-Maffei was chosen as the contractor, and two prototypes were developed in and Between anda total of 17 prototypes were developed. The bore evacuator and the gun's thermal sleeve, designed to regulate the temperature of the barrel, are made of glass-reinforced plasticwhile the barrel has a chrome lining to increase barrel life.
The appearance of new Soviet tanks such as the TB during the late s and early s demanded the development of new technologies and weapons to counter the threat posed to Western armor. In the new TB version entered production, with a new laminate armor protection system; its turret armor, designed primarily to defeat anti-tank missiles, surpassed the TB's in protection. The German government began the development of the Leopard 3, although this was canceled after the fall of the Soviet Union.
The longer tank gun has been retrofitted into the Leopard 2, creating a model known as the Leopard 2A6. A variety of rounds have been developed for Rheinmetall's tank gun. For example, a long line of armor-piercing discarding sabot APDS rounds was developed by Rheinmetall.
The introduction of the longer barrel came hand in hand with the introduction of a new kinetic energy penetrator, the DM With the projectile including sabot weighing in at 8. The new propellant powders, known as surface-coated double-base SCDB propellants, allow the DM63 to be used in many climates with consistent results. A further improved ME4 round with a segmented penetrator to defeat Relikt has been under development since and was to be fielded as the MA4 in Both Germany and the United States have developed several other rounds.
The cap allows the round to impact and embed itself in concrete, then exploding inside the target and causing more damage. Furthermore, the missile can be fired by both millimeter 4. Fragments are shaped to have enough kinetic energy to penetrate body armor. Development commenced infinanced entirely using internal funding, as a response to the Russian introduction of new generation armored vehicles like the T Armata tank, and the first technical demonstrator TD was completed in May Engineers believe the weapon can only be used with an automatic loader and new turret design.
The gun commenced static firing trials at Rheinmetall's proving ground following Eurosatory, while engineers hope to receive a new NATO standard by the end ofalthough development of the gun and ammunition will likely take 8—10 years. For example, the Leopard 2 armed with the 44 caliber long gun, has been sold to the Netherlands, Switzerland, Sweden, Spain, Austria, Denmark, Finland, and other countries.At Eurosatory Rheinmetall is presenting concepts for enhancing the firepower of present and future main battle tanks.

Winchester The swarm descends. This offends my fictional OCD. Anyway, I'm wondering how they're proposing to solve the usual major problems with putting a bigger gun on a tank - or designing a tank around a bigger gun. Historically, size and weight has gone up with every increase in main gun caliber - but we're at the point where a bigger tank would mean redesigning the entire railroad system including all the tunnels and bridges in Europe to make sure tanks can get where they need to go.
Sure, IIRC a fair portion of the network is rated for ton vehicles, but nowhere near as much of it as is rated for 75 tons, which is what is required to drive an Abrams or Leopard over. Another thing that also changes with main gun caliber is ammunition capacity. For each successive generation, tanks have lost around ten rounds of main gun ammunition minimum. The number of rounds per tank has gone from 90 in WW2 75 mm Shermans to ish now, and the mm gunned tanks they were looking at near the tail end of the cold war had ammunition capacities in the 30s.
It got to the point where one of the most well known mm concept was designed around carrying a coaxial 40 mm gun to handle soft-skinned vehicles, because the designers thought they couldn't afford to waste magazine space on HE or HEAT rounds.
And finally the other thing that also changes with each increase in main gun caliber is the reload rate, especially with a human loader. At some point the rounds get too big for a loader to handle, and then you're stuck using an autoloader, which increases the workload of the entire crew when ever they're not in active combat because now three people have to do all the maintenance and guard duty work I am surprised they are making a mm, when mm guns have been tested for ages.
