I thought the USN had installed 57mm Bofors to enhance/fill in the gap between the anti-missile/anti-ship armaments?
The 57mm Bofors gun is only on the Littoral Combat ships (LCS). The gun's effectiveness is unproven. The LCS is not ready for deployment anywhere. It is a very large contraption and vulnerable to Iranian missiles and torpedoes as well as swarming boats. The Bofors gun reportedly can fire only a few seconds before it has to cool off. It is not clear why the Navy took a gun that has no track record in any Navy. Certainly it does not solve the swarming boat problem.

Yup -
For exactly this purpose. Demos are awesome.
The article is kind of silly - talking about the gattling gun.
