Polyamp supply Degaussing systems that minimise the magnetic signature of a vessel.  We also provide systems that measure the electomagnetic signatures of vessels. Below are some common questions.

Is this procedure removing all the magnetism from the ship? 183 8 Isn’t an underwater weapon triggered from some distance by a magnetic field less effective than a hit by a mine that explodes by direct hull contact? 160 9 Is the knowledge about underwater signatures generally the same among the coastal states around the world? 148 10 Is there any training course available for the understanding of underwater signatures and their use for weapon fusing? 145
