Multi Ammunition Softkill System
Multi Ammunition Softkill System (MASS) is a naval self-defence system produced by Rheinmetall of Germany. It is connected to the ship's sensors and protects ships from attacks by advanced sensor-guided missiles by launching decoys that operate in all relevant wavelengths of the electromagnetic spectrum: ultraviolet, electro-optical, laser, infrared and radar. MASS can be either plugged into the command and control module of a naval vessel, or operate autonomously.

Rheinmetall Defence stated that "MASS has attracted orders from 9 nations, for 130 launchers, on 15 different classes of naval vessels" as of 31 March 2009. As of 3 March 2011, this has been expanded to a total order of at least 172 units.[1] Roughly one year later, on the 17 April 2012, the total was 186 launchers for 22 different classes of vessels in 11 different nations.
