why do tanks have smooth bore guns

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). Some artillery still has it, some doesn't. It's known as the extended range, full bore concept. It is most effective in protecting against shaped charges and specially hardened kinetic energy penetrators. 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. When the weapon fires, the smooth surface allows projectiles to move quickly down the length of the barrel. Why do tanks have smoothbore? Why do tankers carry gases have a hemi spherical shape? . The interior of a tank is a very cramped working environment. Smoothbore became less of a liability with modern projectiles/weapons as the accuracy imparted by rifling could be more accounted for. 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. 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. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. Answer (1 of 20): It has everything to do with ballistics. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. Smooth bore tanks decrease the effects from . The cannon made the transition from smoothbore firing cannonballs to rifled firing shells in the mid-19th century. Answer (1 of 5): To stabilize a projectile in flight, to keep it from tumbling, some method must be used. Smooth-bore weapons have barrels with interiors that are perfectly smooth. . Why do modern tanks use smooth bore guns? A smoothbore weapon is one that has a barrel . All p. Answer (1 of 3): Tanks with smoothbore guns use fin-stabilized ammunition, making the rifling unnecessary. 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 . How Do Smooth Bore Guns Work? Description. 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'. 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. On the other hand, rifled-bore weapons fire a single projectile. 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. The gun itself is not the sole factor influencing the range of a tank during combat operations. If you are taking closer shots (less than 100 yards), a smooth bore may be sufficient. 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. 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. Fins do the same thing without eating up energy down the bore of the gun (but they are a later technology). Therefore, forward-and-back surge is very strong. Actually, you are correct. Firearm Discussion and Resources from AR-15, AK-47, Handguns and more! . Rifled guns, while stabilizing the round an. However, to reliably penetrate the thick armor of modern armored vehicles many modern tank guns have moved back to smoothbore. The two most prominent methods are to spin the projectile, or to put fins on it like the fins on a rocket. Whether it's longer barrels, higher calibres, guns for. pocketpotato 9 yr. ago. A smooth bore gun is a type of firearm that uses a bored bore to fire a projectile. 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. 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 . Rifling is used in the bore of a weapon to spin the projectile, but the spin impart. What guns are smooth bore? . 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. The only consistency among the guns of armored fighting vehicles, is that none of them are consistent. The bore is bored out of the barrel so that the gas from the explosive propellant does not have to travel the entire . Throughout the history of tank guns, they have almost . The gun itself is not the sole factor influencing the range of a tank during combat operations. 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. 11 mo. Smooth-bore barrels are well-suited for firing multiple projectiles at the same time. . What is smooth bore tanks? Why do tanks use smooth bore guns? 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 have smooth bore guns? The problem is as a round goes faster; the rifling spins the round faster and fast. Why do tanks have smooth bore barrels? The gun itself is not the sole factor influencing the range . The shotgun is a typical example of a smooth-bore weapon and fires multiple projectiles at a short distance. The premier type of anti-tank projectile used in smoothbore cannons is the armor penetrating, fin stabilized, discarding sabot type . Un-baffled liquid tankers (sometimes called "smooth bore" tanks) have nothing inside to slow down the flow of the liquid. As such. ago. These types of rounds are made accurate by fins (like an arrow) instead of by spinning (like a bullet). Why do tanks raise barrel after firing? 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 weapon, along with the famous 88 mm, was considered one of the best anti-tank guns of the war. The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. A smoothbore weapon is one that has a barrel . The smoothbore design of most modern tank barrels makes it easier for tanks to fire missiles through the same barrel used to fire projectiles. 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. 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 . Why do tanks use smooth bore guns? The development of fin stabilized sabots also removed one of the big advantages of rifling - accuracy. These fire a very long, thin kinetic-energy projectile, too long in relation to its diameter to develop the necessary spin rate through rifling. 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. Why do tanks have smooth bore guns?

Unbaffled liquid tankers (sometimes called "smooth bore" tanks) have nothing inside to slow down the flow of the liquid. The gun itself is not the sole factor influencing the range of a tank during combat operations. By doing this, smooth bore allows the blade to move more easily through the wood, resulting in a more accurate cut. 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. The gun itself is not the sole factor influencing the range of a tank during combat operations. Therefore . The gun itself is not the sole factor influencing the range of a tank during combat operations. Why do tanks have smoothbore? When using a smooth bore, your projectile will still have spin on it because the projectile will be rifled. 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 . . Why do Russian tanks have bricks on them? 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). The gun itself is not the sole factor influencing the range of a tank during combat operations. And loading heavy tank rounds is a tiring processes. What guns are smooth bore? 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 fins fit into the rifled grooves.
