11 mo. The bore is bored out of the barrel so that the gas from the explosive propellant does not have to travel the entire . Why do tanks have smooth bore guns? The weapon, along with the famous 88 mm, was considered one of the best anti-tank guns of the war. These fire a very long, thin kinetic-energy projectile, too long in relation to its diameter to develop the necessary spin rate through rifling. Why do Russian tanks have bricks on them? Therefore . Why do tankers carry gases have a hemi spherical shape? The development of fin stabilized sabots also removed one of the big advantages of rifling - accuracy. Anti-aircraft guns can also be mounted to tanks.. As the tank's primary armament, they are almost always employed in a direct fire mode to defeat a variety of ground targets at all . The shotgun is a typical example of a smooth-bore weapon and fires multiple projectiles at a short distance. By doing this, smooth bore allows the blade to move more easily through the wood, resulting in a more accurate cut. Also, artillery is too broad of a term to really discuss rifling. A smoothbore weapon is one that has a barrel . Answer (1 of 5): To stabilize a projectile in flight, to keep it from tumbling, some method must be used. The main advantages it currently offers are greater flexibility in ammunition use (smoothbore guns can fire fin stabilized rounds, while rifled guns cannot, for example), as well as greatly reduced wear . As such. The cannon made the transition from smoothbore firing cannonballs to rifled firing shells in the mid-19th century. What guns are smooth bore? And loading heavy tank rounds is a tiring processes. Why do tanks have smoothbore? Answer (1 of 2): Most modern tanks (except the Challenger II) fire "armor-piercing fin-stabilized discarding sabot" type rounds, or AP-FSDS for short; these are sub-caliber penetrating rounds that rely on their speed to achieve the penetration of armor. Rifled guns, while stabilizing the round an. Un-baffled liquid tankers (sometimes called "smooth bore" tanks) have nothing inside to slow down the flow of the liquid. Throughout the history of tank guns, they have almost . A smoothbore weapon is one that has a barrel . Hemispherical head A sphere is the ideal shape for a head, because the pressure in the vessel is divided equally across the surface of the head. Buy, Sell, and Trade your Firearms and Gear. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. The gun itself is not the sole factor influencing the range . Actually, you are correct. Therefore, forward-and-back surge is very strong. . . Smoothbore guns have several advantages over rifled guns, such as having higher velocities and longer lives due to reduced friction in the bore, and better performance with HEAT ammunition (. A smooth bore gun is a type of firearm that uses a bored bore to fire a projectile. This report covers tank guns of 115 mm, 120 mm, and 125 mm in calibre, which encompasses the majority of tank guns that have been produced since 1961, when the Soviet Union introduced the T-62 main battle tank (MBT). Why do tanks have rifled barrels? If you are taking closer shots (less than 100 yards), a smooth bore may be sufficient. Answer (1 of 20): It has everything to do with ballistics. The gun itself is not the sole factor influencing the range of a tank during combat operations. Smoothbore became less of a liability with modern projectiles/weapons as the accuracy imparted by rifling could be more accounted for. Additionally, with the increasing velocity of tank AP shells, rifling was under serious wear, so smoothbore guns could fire sabot rounds faster, and for longer before needing replacement. Whether it's longer barrels, higher calibres, guns for. Spin stabilized (rifled barrels) rounds become less and less stable as velocity increases (around 3500 -3800 fps), the rounds begin to yaw around the axis. The only consistency among the guns of armored fighting vehicles, is that none of them are consistent. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. When the weapon fires, the smooth surface allows projectiles to move quickly down the length of the barrel. The fins fit into the rifled grooves. The gun itself is not the sole factor influencing the range of a tank during combat operations. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. How Do Smooth Bore Guns Work? The premier type of anti-tank projectile used in smoothbore cannons is the armor penetrating, fin stabilized, discarding sabot type . ago. 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. On the other hand, rifled-bore weapons fire a single projectile. Elevating the gun barrel after firing a shell likewise lowers the breach of the gun making it easier, a bit quicker and less fatiguing to reload the gun. The gun itself is not the sole factor influencing the range of a tank during combat operations. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. Just to add some extra info on this subject - like u/pnzsaurkrautwerfer said projectiles coming out of a smoothbore cannon are stabilized by a set of fins on the rear of the projectile. Science. Firearm Discussion and Resources from AR-15, AK-47, Handguns and more! Why do tanks have smooth bore guns? Fins do the same thing without eating up energy down the bore of the gun (but they are a later technology). It is necessary to limit the scope of this study, and the increase of Soviet tank gun calibres from 100 mm to 120 mm in 1961 . The problem is as a round goes faster; the rifling spins the round faster and fast. Why do tanks have smooth bore barrels? . Weighing in at 55 tons, it had a high degree of mobility with a Honeywell AGT1500C multi-fuel turbine engine, generating 1500 hp and giving the tank a top speed of 45 mph (72.5 km/h). pocketpotato 9 yr. ago. . Answer (1 of 3): Tanks with smoothbore guns use fin-stabilized ammunition, making the rifling unnecessary. Some tanks still have rifling. Rifling is used in the bore of a weapon to spin the projectile, but the spin impart. The first tank with a smoothbore gun was the Soviet T-62, introduced into service in 1961; today all main battle tanks except the British Challenger 2 and Indian Arjun MBT use smoothbore guns. It's known as the extended range, full bore concept. Why do tanks raise barrel after firing? However, to reliably penetrate the thick armor of modern armored vehicles many modern tank guns have moved back to smoothbore. Reactive armour is a type of vehicle armour that reacts in some way to the impact of a weapon to reduce the damage done to the vehicle being protected. All p. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. Why do tanks use smooth bore guns? Why do tanks have smoothbore? The gun itself is not the sole factor influencing the range of a tank during combat operations. Rockets keep going by burning propellant in mid-flight, but at relatively low velocities (they usually use some kind of shaped charge as a warhead, which blows a hole in armor from outside) that does not depend much on the velocity of the . The gun itself is not the sole factor influencing the range of a tank during combat operations. Consider a modern full-rifled 12-gauge slug gun firing a high-tech 260-grain sabot slug that leaves the muzzle at about 1,900 fps velocity. What guns are smooth bore? The Russian navy conducted experiments with large-caliber smoothbore naval guns, which were halted by budget cuts. What is smooth bore tanks? A smooth-bore weapon has a barrel that is completely smooth on the inside, while a rifled-bore weapon has grooves that help guide a bullet down the length of the barrel. Smooth-bore barrels are well-suited for firing multiple projectiles at the same time. The interior of a tank is a very cramped working environment. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. Smoothbore allows for better firing of sabot rounds -- the shot itself is much narrower than the barrel, but runs down the length of the barrel inside a lightweight 'shoe'. The two most prominent methods are to spin the projectile, or to put fins on it like the fins on a rocket. Why do tanks use smooth bore guns? When using a smooth bore, your projectile will still have spin on it because the projectile will be rifled. . Why do modern tanks use smooth bore guns? Smooth-bore weapons have barrels with interiors that are perfectly smooth. An in-depth review of why most modern tanks don't use rifled guns.All credit for the photos used in this video goes to their owners in the links below. Smooth bore tanks decrease the effects from . These types of rounds are made accurate by fins (like an arrow) instead of by spinning (like a bullet). It is most effective in protecting against shaped charges and specially hardened kinetic energy penetrators. The gun itself is not the sole factor influencing the range of a tank during combat operations. The gun itself is not the sole factor influencing the range of a tank during combat operations. Description. Answer (1 of 17): Short answer: More optimal for long range engagements among other things Long answer: Spinning a projectile resulting in increased accuracy as accidentally discovered during the civil war where gunsmiths wanted to reduce the contact surface of the bullet and the barrel. . Each type of weapon has specific uses and differing levels of power and accuracy. Some artillery still has it, some doesn't. A tank gun is the main armament of a tank.Modern tank guns are high-velocity, large-caliber artilleries capable of firing kinetic energy penetrators, high-explosive anti-tank, and cannon-launched guided projectiles. Unbaffled liquid tankers (sometimes called "smooth bore" tanks) have nothing inside to slow down the flow of the liquid.
