The MU90 is capable against any current or perceived threat, including a bottomed stationary mini-submarine, known versions of anechoic coatings, and various decoys. It is also capable of launch speeds up to 400 knots (740 km/h; 460 mph), allowing it to be dropped from maritime patrol aircraft flying at high speeds, or rocket-assist launchers. Powered by an electric pump-jet, it can be run at "silent" speeds to avoid giving its location away to the submarine, or "dash" at speeds over 29 knots.[5] It uses a shaped charge warhead that can penetrate any known submarine hull, in particular Soviet double hull designs, while remaining just as deadly in shallow waters where conventional warheads are less effective.
