Here's a more typical view of one of the USS Iowa's 5in/38 Mk.12 turrets.
This is what is referred to as a "twin-gun" turret, because both guns elevate and depress on the same axis. The big 16in Mk.7 turrets, by contrast, have three guns that can pivot independently to different elevations --- as a result, it's called a "three-gun" turret, not a "triple-gun" turret.
The Mk.12 always seems to get the short end of the stick on the Battleships, being in the shadow of big 12in, 14in, and 16in guns, but it's an extremely powerful and versatile weapon that commands respect from everyone who knows what it's capable of.
For example, consider these facts...
- The Mk.12 is what's known as a "DP" ("Dual-Purpose") gun, because it can be used against air targets as well as surface targets.
- The Iowa class Battleships had the largest battery of Mk.12s ever fitted to any single warship during World War 2, making them the most powerful anti-aircraft warships ever to go to sea. Only the advent of the Surface-to-Air Missile and Close-In Weapon Systems have more powerful air defenses become possible.
- A single Mk.12 twin turret can fire 22 rounds every minute --- with 12 of these on a modernized Iowa class Battleship, up to 264 rounds-per-minute!
- With a magazine of 3000 5in shells, the aforementioned 264rpm barrage can be continuously maintained for more than 11 minutes.
- Within a range of 13000yds, the Iowa's Mk.12s alone can simultaneously engage up to 10 air and surface targets simultaneously (though obviously, fire control would likely be poor when engaging so many targets, unless they're all in the same direction).
- During the Vietnam War, the Mk.12s *alone* on the USS New Jersey (a sister ship of the Iowa) destroyed or seriously damaged 68 structures 54 bunkers, 2 artillery sites, 9 watercraft, and caused 32 secondary explosions --- in 1968 alone; in it's 1969 tour, the New Jersey's Mk.12s destroyed or seriously damaged 80 structures, 78 bunkers, and 6 mortar sites, caused 14 secondary explosions, and stopped 7 troop movements.
Here's more detailed information on the Mk.12;
