The arrow is made of a very dense material like Tungsten of Uranium and you have a sabot around is in the barrel to it get up to full diameter. 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.

As a multi-fuel engine, the AGT 1500 can run on diesel, kerosene, gasoline and high-octane jet fuel.
