Missiles: Do they ever miss???

[Aussie Gamer]

Missiles brain would not be that powerful that they would be able to have several ways of detecting an enenmy ship.
If you look at missiles of today then the set and forget missiles lock on one thing such a the heat of the engines or even the radar signal being sent out by the enemy unit.
The Exocet missile worked in one war but now a ECM device has been devoloped to stop it from hitting the ship.
Chaff is used to stop radar using missiles.
Flares are used to stop Infra-red missiles.
A modern ECM pod senses to frequency of the incoming homing missile and sends a fake signal back to send it the wrong direction.

Missiles are very venerable to the ECM of the target.
