Why don t tanks use rifled barrels?
The majority of modern tanks are fitted with smoothbore guns, which do not utilise rifled barrels in order to impart spin to projectiles as they are fired (see Annex B). HESH ammunition is used both as a general-purpose high explosive projectile, and also against other tanks and armoured vehicles. …
Why is smoothbore better than rifled?
The chief advantages of smoothbore designs are their greater suitability for fin stabilised ammunition and their greatly reduced barrel wear compared with rifled designs.
Is a rifling barrel better than smoothbore?
Range and Accuracy Rifled-bore weapons, such as the modern high-powered hunting rifle, are extremely accurate. Smooth-bore weapons are far less accurate and usually are used for short range. The shotgun is a typical example of a smooth-bore weapon and fires multiple projectiles at a short distance.
What is the advantage of smoothbore?
Basically, the major advantage of rifled guns is the use of HESH rounds, and the major practical advantage of smoothbore guns is that they have a long life, and for Eastern tanks, that they can fire missiles.
Why do tanks have smoothbore?
The reason tank guns are smoothbore is the switch from HEAT (High Explosive Anti-Tank) to kinetic energy rounds sabot as the primary anti-tank round. Kinetic energy rounds are subcaliber rounds (smaller than the bore) and aren’t effective if the spun by rifling.

What is the difference between rifled and smoothbore?
What’s the difference? A rifled barrel has lands and groves that cause the projectile to spin when it exists the muzzle (end of the barrel). A smooth bore is exactly how it sounds, smooth. A smooth bore has no lands and grooves.
What are the advantages of rifling?
Rifling imparts spin to the bullet along the latter’s lengthwise axis. This helps the bullet maintain a stable trajectory when it leaves the gun and enhances both the range and target accuracy of the gun.
What is the purpose of rifling?
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun’s barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its …
What is a smoothbore barrel?
A smoothbore weapon is one that has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars.
Are rifled guns still used in tanks?
Rifled guns are still in use, but technology has caught up that allows the advantages of Smooth-bore guns to come into play while mitigating the disadvantages. Rifled Guns. Rifled guns were originally the mainstay of the majority of tank cannons.
What are the advantages of an rifled cannon?
Rifled guns were originally the mainstay of the majority of tank cannons. The biggest advantage that they provided was that they were consistently more accurate than tanks with smooth-bore guns.
Does a rifled barrel need to be rifled?
Because the barrel is rifled, the projectile does not need to be rifled. A rifled slug is what you want to shoot out a smooth bore barrel. Because the barrel is smooth, the projectile will not rotate appropriately unless it has rifling on it.
Why do tank guns favor smoothbore ammo?
Presently, tank guns favor Smoothbore because the current state of the “Armor vs Gun” dynamic for tanks favors a type of armor that is best penetrated by a type of ammunition that doesn’t play well rifled barrels.
