Hmm, a 155mm howitzer, a minigun, and I guess for the third, one of those automated anti-aircraft/anti-missile guns they have on naval ships.

You mean a Phalanx?

And you might want a quad 50, too.

Those 155 howitzers are noisy. An antiaircraft laser like Israel was using. against. rockets would be a good quiet start. A radar aimed gun off a battleship would help.
