The Swedish-built Mk 110 naval gun—internationally known as the Mark 3—is one of the most advanced ship-mounted artillery systems in the world.
“The key is accuracy, rate of fire, and programmable ammunition,” said BAE Systems representative Scott Thompson in the YouTube video below.
While the Mk 110’s predecessors—the Mark 1 and Mark 2—are highly effective against large heavily armored targets, they are inefficient against today’s fast-moving threats, such as unmanned aerial vehicles, anti-ship missiles, and speedboats.
The Mk 110 on the other hand, can fire 220 rounds per minute at targets nine miles away with an intelligent and highly destructive 6-mode programmable 57-mm Mk 295 munition. The munition is a pre-fragmented, programmable, proximity-fuzed round that can explode on contact or deliver a shotgun effect with more than 8,000 pre-formed tungsten fragments. The gun’s digital fire control system responds to precise pointing orders and selects the munition fuze in fractions of a second upon firing.
The Mk 110 naval gun fires up to 220 rounds per minute.
Each round accelerates to 3,500 miles per hour.
In air burst mode, the round detonates in mid-air above the target.
The proximity mode uses a miniature radar system to trigger the fuse when the round gets close to the target.
The impact mode explodes the round on contact.
The Mk 110’s flexibility makes it the deck gun of choice for the U.S. Coast Guard’s National Security Cutter and offshore patrol cutter ships, as well as for the Navy’s Littoral Combat Ship (LCS). This American Heroes Channel video perfectly shows the Mk 110’s efficiency and power.
