Why do modern tanks have smooth bore guns?

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). 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 is the Abrams smooth bore?

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.

Why don’t modern tanks use rifled barrels?

Thats why most (not some) modern tanks use smooth bore guns as opposed to rifled. Rifling in a weapon’s barrel generally increases accuracy, but it negatively affects muzzle velocity and penetration value.

How did tanks get so powerful in WW1?

The result was progressive increases in the calibre of tank guns, the development of new types of ammunition with greater armour-piercing capabilities, and the introduction of more sophisticated fire-control systems to improve tank guns’ ability to hit targets.

What tanks have the same 105mm gun?
