Incendiary projectiles
Chaff (radar interference) projectiles
Rifling a gun barrel causes the projectile to spin in flight, keeping the projectile from tumbling after it leaves the barrel and ensuring greater accuracy and range.

Fuse
The proximity-fused (VT) shell is designed to detonate at a position that will cause the greatest damage to that target. A VT fuse contains a radio transceiver that emits pulses of radio energy and receives a portion of these pulses reflected back from the target. When the returning pulse is strong enough, it will set off the fuse.
