It is used by Navy ships to reduce their magnetic signature, making them less vulnerable to certain types of mines.

The chrome-lined muzzle booster also burns any remaining propellant thus reducing the gun's signature.

Some military uniforms are treated with chemicals to reduce their infrared signature.

It also reduces the ship's thermal and sound signature.

Unlike the previous Lindau-class minehunter, the vessel was built from glass reinforced plastic to reduce her magnetic signature.

Their vehicles even had upgraded mufflers to reduce their sound signature.

This "single vehicle solution" reduces its signature - it cannot be easily detected by satellites - and makes its deployment easy.

They have been used against submarines, as submarines sometimes lie on the seafloor to reduce their acoustic signature.

The ships use wooden hulls to reduce their magnetic signature.

Probably to reduce their electronic signature, he told himself.
