This 57 MM Mark 110 Naval gun is used on the new Freedom Class ships.  These ships can attain speeds of 52 mph and are driven by pumps that can empty an Olympic sized pool in three seconds.

The rate of fire is 220 rounds per minute and the projectiles have fuses with built in radar that can be programmed to detonate by proximity or time/distance. The elecronics sustain 60,000 G's at the moment of firing.  At that G level a baseball has an effective weight of 8.5 tons.

The MK 110 gun developed by BAE Bofors, Sweden, as the 57mm MK3, was competitively selected for installation on the United States Coast Guard (USCG) cutters and Littoral Combat System (LCS) class ships. It is designed to engage surface, air and missile targets. The current version of the 57mm gun was designed in 1995 and introduced into service in Sweden on their Visby class corvette in 2000. The MK 110 Mod 0 Gun is assembled at the BAE Systems facility in Louisville, Kentucky.

The gun mount includes a 120 round automatic loader drum. The maximum firing rate is 220 rounds per minute. The gun is normally operated by remote control from the fire control system (FCS) by one operator but can be controlled locally in the gun mount. Additional rounds can be accomplished by the full crew (mount captain and two designated ammunition loaders), all of which are stationed below deck. 

The MK 110 gun is installed aboard LCS and USCG WMSL class ships.
