yea like flare/chaff is able able to detonate an incoming missile. Cmmon if flares and chaffs don't detonate missile why should sub countermeasures do?
Look at WWII type torpedo fuse: magnetic and impact.
I bet there's no magnetic field generated by a countermeasure and obviously impact fuse won't detonate either. If topedo does explode on countermeasure why does Oliver Hazard Perry class employ a nixie topedo decoy? The safest would be to throw lots of CMs and the threat torps would explode on them.
In short CMs only spoof/fool the sensor/homing devices and has got no effect on detonation devices/fuses. I think
But then again one could question how do you know that chaffs and flares don't detonate incoming missiles? I know because if chaffs and flares do detonate incoming missiles, all tanks would have employed them. I don't see any tanks employing a flares dispenser(only smoke and anti missile missile system). The reason tanks don't employ flares dispenser is because their land speed is infinitely small compared to the incoming missile speed so spoofing the missile sensor would be ineffective as the location of that tank is relatively unchanged. I think.
