 The advantage of an anti-submarine missile is the attack stand-off range.The Swedish Bofors 375mm m/50 Anti-Submarine Warfare (ASW) rockets, in the past commonly used by Sweden, France, Japan and Germany for instance, can travel as far as 3600m depending on the rocket used.The USSR developed its own anti-submarine rockets in the RBU series and these are still in use in Russia and in countries using Russian designed ships.
