. 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. Roughly one year later, on the 17 April 2012, the total was 186 launchers for 22 different classes of vessels in 11 different nations.
