  1. Are there any similar videos around, which go in some greater detail about the guns? Always wanted to look, what are the differences between smootbores and rifled ones, how do they do the upkeep, maintenance, and some more advanced stuff about amoo, etc. This video was good, but way too short..

    • Smoothbore is fragile ( from what i know, T-72 could fire about 120 times before changing gun barrel). Since HEAT ammo is now completly useless againts modern reactive armor (or you need two charge warhead which is too big for tank shell), kinetic penetrators (APDS,APFSDS) are used, and since they are sub-caliber and some fin stabilised, there is no point in rifling.Even modern HEATs are usually subcaliber (whcih can be use to kill helicopters :) like M830A1 HEAT MP-T) Smoothbore allso allows to fire cannister rounds or guided projectile (Israeli LAHAT)
      But main fact with rifled guns is, that longer shell is, the more spin it needs. Modern shells simply reached the point where lenght do diameter ratio is to big to be stabilized wirh rifling.

      • Some nice reply :)

        So, in comparison to smoothbore, how many times modern rifled barrel could fire before it needs to be replaced? (modern, as in, when they were still in use)

  2. Does anyone know what the background music is? I really like it and have been searching for the music for the first few Nuts and Bolts videos for some time.

  3. I remember reading about a Canadian WWI tank commander who walked into battle alongside his tank using a lump hammer to give directions to his crew!

  4. “The most powerful mass produced tank gun” IS-2 122mm, they really needed to mention a Russian tank or? so the 12,8 AA gun from the germans just disappears in the dust RUSSIA Stronk…

    • Thats what i thaught…

      Conveniantly forgetting about the Jagdtiger?

      But hey, its WG what else to expect… :P

      • Well…from their point of view, Jagdtiger is not really a mass-produced tank, I guess.
        Still, I think IS-2′s 122 is still not as powerful as King Tiger’s long 88.

        • but the 12.8cm guns used on the jagdtiger were mass produced, they just had not had the time to make very many, and not enough jadgtiger chassis were ready, but they were in production, and used in towed AT guns, of which there were a few around. but i guess that’s not a tank. The 88mm L71 had much more penetration and velocity than the 122mm, but the smaller caliber made it that less explosives could be fitted inside the shell, but it made up for it with the extra kinetic energy form the grater velocity. they were just about equal in “power” these two guns, they just got that “power” in different ways. the 88mm would have more penetration, but the 122mm would retain momentum better at range because of the grater mass, thus a lower penetration loss rate, so its very hard to make a clear choice to which gun is “better” or more “powerful”. they are cool videos though.

  5. I really don´t think that HEAT ammo melts the steel after impact as they mention – from what I know, it utilizes pressure made by explosives to cut through armor, temperature is just side effect of this pressure, and is not important at all.

    • The projectile is solid but acts like a liquid in the contact with the armor, due to the high velocity. The front end of the jet can move ~10000 m/s.

      Plasma, gas or liquid it is not, nor is the armor melted per se, it’s just pushed away.

    • Actually it uses the pressure from the explosive to transform the copper lining inside it into a jet that has so high pressure it pushes the molecules in the armor apart.

      But you are indeed correct, “melting” the armor is pure bullshit.

  6. the thing about AA guns being good for tanks is complete bull…it causes a shitload of problems… -_- get your shit right WG

    • Ehm… no it is not. AA guns were very often modified into tank cannon as they usually had extremely high gun velocitys, and readily available ammunition,

      The British had 3 inch, 3.7 inch and 4.5 inch guns that were modified from AA

      The American M1/2 90mm gun was their ubiquitous AA gun of the time, there were thousands of them kicking about before we started sticking them in tanks like the slugger and later the Pershing.

      The germans obviously had their famous 8.8 cm Flak 18/36/37/41, as well as their 10,5cm Flak 38/39, and even the 12,8cm FlaK 40, all of which were adapted for direct fire roles at one time or another.

      The Italians used their 90mm Cannone da 90/53 in a dual AA/direct fire role.

      The Soviets very successfully modified their 85mm AA gun for both tank and AT use, the gun was extremely well produced for both roles with many thousands of examples being made.
