The Tank Museum On The T-14 Armata

Sunday, May 28th, 2023

We’ve already covered why Russia’s T-14 Armata tank isn’t all that. Here’s a somewhat more balanced look from David Willey of The Tank Museum:

The first ten minutes covers the basics of Soviet tank design (the philosophy of favoring firepower over just about everything else, and how political rivalries led to various Soviet tank designs). Then he goes into the details of the Armata.

  • Much of the Armata comes from the abandoned T-95 project. “Although the T14 is looked at as new, it actually relies on systems and ideas from some much earlier projects.”
  • “The smoothbore 2A821M 125mm cannon is an upgrade from the weapon on the T-90. Russian sources claim its muzzle energy is far greater compared to the Rheinmetall 120mm gun.”
  • The unmanned turret means no need for a fume extractor.
  • Theoretical fire rate of 10-12 rounds a minute. I suspect this is highly optimistic and the fire rate is probably the slower one round every ten seconds we already covered.
  • “The new Vacuum One armor-piercing, fin-stabilized, discarding-sabot round is fitted with a 90cm [900mm] long rod penetrator. That’s unusually long. It is said to be capable of penetrating one meter of rolled homogeneous armor at about 2000 meters.” That is quite long. The rod penetrator on the U.S. M829 APFSDS round is 684mm long. Western consensus seems to be that the Vacuum One and Vacuum Two penetrator cores are made of depleted uranium or tungsten.
  • “The A853 engine was a copy of a German x-shaped engine from the war years…the A853 was not however a reliable product, and from all reports it seems to have had major issues.”
  • When working, it theoretically has twice the horsepower of a T-72 engine and capable of reaching 56 miles and hour with a range of 500 kilometers.
  • “The T14 has new 70 centimeter diameter road wheels, and an electronically adjustable suspension system on at least the first two road wheels, and possibly the last ones, and [that’s] called an active suspension system but is fitted over a main torsion bar suspension. It also has rubber-blocked tracks.”
  • The Armata’s sealed crew compartment will have air conditioning, which was introduced in Russian tanks with the T-90M in 2016. (Starting with M1A2 SEPv2, the Abrams has cooling, but it’s mainly geared toward cooling the electronics.)
  • Digital screens with remote cameras.
  • “The gunner can see his target, but he can also choose through those screens a relevant ammunition type.”
  • “The chassis and turret are equipped with a ‘Malachit’ dual explosive reactive armor system, and on the front sides and the top there’s stealth coatings.” Assuming the ERA is actually there and not fake, as on so many captured and destroyed Russian tanks in Ukraine.
  • “The active protection system has a radar to detect and tract incoming anti-tank munitions it states a maximum speed of incoming interceptable target is 1700 meters a second, or Mach 5.” Let’s just say I have grave doubts that it actually works. The Pentagon went with Israel’s Trophy active protection system over Raytheon’s homegrown Quick Kill system for M1A2 SEPv3, and Raytheon is good at developing reliable, high tech weapons. Unlike Russia.
  • “The top of the vehicle is still vulnerable to top attack munitions.” So much for defense against Javelin. Which first entered service in 1996.
  • “However, on closer inspection a number of these technologies and features are not fitted to some of the vehicles. Some you can see there’s covers where the technology or that piece of equipment should be on others is fitted for, but not with.” And that was on parade demonstration vehicles before sanctions. Odds that Russia would have enough parts to fully equip high tech parts to all Armatas supposedly in Ukraine would appear to be slim.
  • Though reusing a lot of features from the abandoned T-95 project, “the new T14 tank is a radical departure in sense of its scale, its layout, its design features and technology from that era of evolutionary Soviet-designed vehicles.”
  • “Originally intended to replace all Russian army tanks, the Russian military had planned to acquire about 2,300 T-14s between 2015 and 2020…but by 2018, delays were announced until at least 2025. Subsequently announcements indicated the apparent cancellation of the main production run.” In between it announced it was going to build 100 of them, though that number may have included other armored vehicles using the same platform.
  • “The [Russian] Deputy Minister of Defense said, quote, there is currently no need to mass produce the Armata when it’s older predecessors, namely the latest variants of the T-72, remain effective against American, German, and French counterparts.” Here the Deputy Minister of Defense is engaged in a time-honored Russian rhetorical device known as “lying his ass off.”
  • “The gradual tightening of sanctions, and then with the Russian invasion of Ukraine, the problem of sourcing the essential microelectronics has come to the fore. Russian industry has been critically dependent on foreign microelectronics and associated technologies. These are no longer available due to sanctions.”
  • “The sights from France and other components are no longer available.”
  • “Other issues come into play that affect the wider Russian defense industries. One is the perennial Russian problem of corruption. Since 2011, a staggering 72,000 officials have appeared before the course on corruption charges.”
  • “The mythic way many Russian military systems and products have been promoted and sold has met a crushing reality in Ukraine.”
  • Even though there may only be 20 test vehicles available, there is an expectation they will make appearance in the battle. A British ministry defense statement said, and I quote, any T-14 deployment is likely to be a high-risk decision for Russia. 11 years in development, the program has been dogged with delays reduction in planned Fleet size and reports of manufacturing problems. If Russia deploys a T-14 it will likely primarily be for propaganda purposes. Production is probably only in the low tens, while commanders are unlikely to
    trust the vehicle in combat.

  • So even a balanced, objective analysis of the T-14 Armata isn’t particularly optimistic about its chances in combat.

    An In-Depth Look At The RPG-7

    Saturday, April 8th, 2023

    Chris Copson of The Tank Museum has an in-depth look at the RPG-7 and its history as an effective hand-held tank-killing weapon and poor man’s artillery.

    Some highlights:

  • How a HEAT RPG charge works: “There is a trumpet-shaped liner in this section inside an aerodynamic fairing. And behind that is a copper cone, and underneath that is the RDX explosive charge. When that detonates, it fires what’s effectively an enormously powerful bolt of kinetic energy forward. That’s what’s called the Munroe effect, and it will penetrate up to 260mm of rolled homogeneous armor.”
  • The Russians were thought to have lost over 100 tanks in Grozny during the first Chechan War.
  • Seven of eight U.S. helicopters brought down in Afghanistan were from RPG fire.
  • Four Black Hawk helicopters taken down in Mogadishu were taken down by RPG fire.
  • Methods evolved to combat RPGs include explosive reactive armor, improvised outer armor, and slat armor.
  • “Can an RPG 7 round penetrate the composite frontal armor of the modern main battle tank? No, it can’t. But it was never intended to.” But the more modern RPG-29 can.
