Silent Hunter III Edit
The weapon is seen in use from 1942 and onwards.
|“|| A bigger threat to the U-boat was forward-throwing weapons such as the Hedgehog, a salvo of 24 projectiles landing simultaneously in an elliptical pattern over the U-boat's suspected position. The attack is delivered while still maintaining ASDIC contact with the target, making it a much more accurate weapon. In addition, the projectiles would only explode on contract with the U-boat, which meant no ASDIC blind zones would be created unless a hit was scored.
There's little to be done to escape a Hedgehog's attack expect increase speed and depth and change course. Without the aid of an external camera, the only hint of the attack you may get is the noise of the 24 projectiles entering water - which may be too late.
Fortunately, a single Hedgehog is not a very powerful weapon. It carries a very small explosive quantity, and thus lacks the potential for a catastrophic kill.''
