The Russian navy conducted experiments with large-caliber smoothbore naval guns, which were halted by budget cuts. Location. Re: Smooth bore vs rifled barrels in Tanks? Britain is the only user of rifled ammunition . The first Soviet 152mm tank gun project was called Object 292. 2,527. A person would use a rifled barrel if they are looking at shooting longer distances. The 100 mm rifled gun on the T-55 could not penetrate the front of the M48 Patton III, and the Americans were . On the other hand, rifled-bore weapons fire a single projectile. Therefore, if you want to find 12 Gauge Shotgun Rifled Barrel by specific location, please type "12 Gauge Shotgun Rifled Barrel + location" in the search box, then click the "enter" button. Rheinmetall's 130 mm smoothbore technology for main battle tanks (MBT) embodies a significant lethality leap in times of more sophisticated protection systems and increasing threats. T-62: Return of the Smoothbore. It was basically a modified T-80BV, re-armed with a 152mm gun called LP-83 by the Kirov plant in Leningrad (St. Petersburg) in mid-1980s. The first tank with a smoothbore gun was the Soviet T-62, introduced into service in 1961. Maybe also there are higher velocities with the smooth bore. Rheinmetall's 120 mm tank gun is the most widely fielded non-Russian tank gun and holds a virtual monopoly on NATO and Western-allied tank armaments; currently, most Western main battle tanks (MBTs) are armed with smoothbore 120 mm Rheinmetall cannons, except the UK which uses a rifled 120 mm cannon, and the French who engineered their own . The reason why rifled guns have all but . Alot of people wonder why tanks like the Challenger 2 still uses a rifled tank gun when most tanks now use smoothbore guns. At the same time a variant, the T-62A, with a rifled gun was also deployed. It also had a 7.62 mm PKT coaxial general-purpose machine gun with a firing capacity of 2,500 rounds. Compared to the 120mm Smoothbore gun now in use, or really to any other tank cannon, the 105mm has 3 great advantages that no other gun can match. So really, if they can shoot APFSDS(like Kozzy Mozzy said), they have no reason to change their main guns. The rifled barrels, when shot with Sabot slugs, will be way more accurate, and you will also have more reach. Smoothbore is better tank busting. GD. Answer (1 of 12): The purpose of rifling in a barrel is to impart 'spin' to the shell. #1. The "120-mm" designates that the cannon fires 120-mm-wide rounds. Comparing Accuracy of Rifled vs. A rifled gun can fire specially designed types of this ammunition but it is generally cheaper and easier to use a smooth-bore. A smooth bore does not encourage the projectile to spin like a rifled barrel does. Although the 21st century's M1 Abrams main battle tank utilizes the same caliber of main gun, 120mm, the M103's cannon was a rifled gun firing a separate-loading round, in which the projectile was loaded into the breech, followed by a cartridge case consisting of a brass case, primer, and propellant in a fixed unit. The T-90 tank is not new, went into production 1995. If you already have an M3 and want a Slug Gun, why would you consider an M4 (a smoothbore, tactical shotgun similar to your M3)? -9. +6. Today all main battle tanks field them except the British Challenger 2 and Indian Arjun MBT. Maybe the fin stabized ammo is the answer.Both the Abrams and the T-90 use this ammo. there are a few exceptions - none of them very important. Improvements to the Challenger 2 will cost £800 million ($1 billion) for all tanks in service, or £5.4 million ($6.6 million) per tank, and will the integrate a new smoothbore cannon to replace the older rifled one, a new digitised turret, improved sights and upgraded protection. This separate-loading system necessitated the use of two loaders. This stabilizes the round so that it flies straight. October 22, 2012 at 5:59 pm #1106750. In the late 1950s, the Soviet government received information that NATO nations developed and adopted new 105 mm tank guns, which made the T-54 and T-55, the most common types of Soviet tank, vulnerable. Maybe also there are higher velocities with the smooth bore. In the 1960s smoothbore tank guns were developed by the Soviet Union and by the experimental U.S. German MBT-70 project. Loads for a smooth bore won't matter that much at all. Newton's law that force equals mass times the velocity squared explains much. The British weapons development took rifled tank guns as far as technology allowed. You get APFDS shells out of it perfect for perforating T72 and the like. Posts: 95.

Re: Smooth bore vs rifled barrels in Tanks? The lethality of the conical rifled round vs a ball fired from a smooth bore is a function of physics. Based on their experience with the gun/missile system of the BMP-1, the Soviets produced the T-64B main battle tank, with an auto-loaded 125 mm smoothbore high-velocity tank gun, capable of firing APFSDS ammunition as well as . Fin stabilized projectiles fired from smoothbore barrels are still very accurate when fired from a tank with a modern fire control system. A tank has 3 major components-Armament,Mobility and Protection.Kanchan composite armour gives requisite protection for Arjun tank as expected from 3rd generation Tanks.Hydropneumatic suspension and German MTU engine cover sufficient performance in Mobility department.Armament is the major unsatisfied area as expected from a 55 ton weighted tank. The British Army has a total of 386 BAE Systems Land Systems Challenger 2 MBTs all armed with a 120 mm L30 rifled tank gun.

The principal upgrade of the Challenger 2 will involve swapping out the current L30 120mm rifled gun for the high-pressure L55A1 smoothbore cannon. Re: Smooth bore vs rifled barrels in Tanks? less barrel wear, as there is no rifling required to remain within tight tolerances, thus barrel life is a lot better (1,500 vs 400 rounds EFC) due to not having to . Re: Smooth bore vs rifled barrels in Tanks? Aug 17, 2014. FineScale Modeler magazine - Essential magazine for scale model builders, model kit reviews, how-to scale modeling, and scale modeling products. 105mm M68A1 rifled main gun: The main armament of the original model M1 was the M68A1 105mm rifled tank gun firing a variety of high explosive anti-tank, high explosive, white phosphorus and an anti-personnel (multiple flechette) round. This gun is a license-built version of the British Royal Ordnance L7 gun. Smoothbore guns offer the following advantages over rifled guns: less internal contact area between the barrel and the projectile, meaning less velocity is lost due to friction. Manufactured by Rheinmetall, it's smoothbore because of the primary round fired - APFSDS - or armor-piercing fin-stabilized self-discarding sabot. The original M1 Abrams was armed with a 105 mm M68A1 rifled cannon and was the US military's first vehicle that was deployed with base composite armor. The Mark 45 5/54 naval gun is rifled. Production began in 1974, with the first version of the gun, known as the L/44 as it was 44 calibers long, used on the German Leopard 2 tank and soon produced under . However, it takes a great deal of energy to force the round to spin as it goes down the barrel, subtracting some of the 'punch' it could deliver. The T-90 tank is not new, went into production 1995. Wingbone's experience is an outlier. for the 120 mm smoothbore it is 5. There were various types of rifling - a barrel might start rifled and the rifling decreases until it does not exist at the muzzle, or the twist of the rifling might increase or decrease along the bore. Rifled lets you use more HE/ HESH/HEAT conventional shells good for blowing apart barriers. So distance between tier X and hypothetical tier XI with smoothbore guns and all advanced stuff either would be too big (think tier VIII vs X every time), or tier XI performance would be laughable and probably ahistorical even for WG standards. The H & R Pardner Pump twelve gauge would be the single most cost effective shotgun for someone looking to purchase their first rifled barrel shotgun at a low cost.
