frag

2
New cards

Isotropic fragmentation warheads

Spread equally sized fragments evenly across a sphere

3
New cards

Non-isotropic fragmentation warheads

Direct fragments into a more contained area to maximize impact at a desired location from the warhead

4
New cards

What is Circular Error Probable (CEP)?

The radius of a circle about the aim point inside which there is a 50% chance that the weapon will impact/detonate (Phit = 50%)
