Can the New Jersey shoot straight up?

How about a 16inch round from USS New jerseyGG

I think it can launch cruise missiles at a high angle,
and some of the smallest guns might shoot straight up,
but the 16-inch guns have a maximum elevation of 45º.
I have a photo of a cutaway diagram of the New Jersey's
16-inch guns, that at one point says, "Guns can be inclined
individually from -5 degrees to 45 degrees, at a rate of
12-degrees per second." There are 3 turrets with 3 guns
each, 1700 tons rotating weight per turret, and basic
rounds are either 2700-pound AP or 1900-pound HC. Minimum
crew size is 77 men per turret and fire rate is two rounds
per minute per gun. The maximum range of an HC round
is "41622 yards when fired with the normal propelling
charge of 660 pounds, with a muzzle velocity of 2690 feet
per second".
