  Turner Joy
The Turner Joy was a typical early Cold Warrior, in many ways. This was a late fifties destroyer, designed to operate in a potentially nuclear environment, but neither powered by nuclear means, nor equipped with nuclear weapons. So by most standards, it was not a nuclear ship, and yet it was firmly set as a nuclear warrior. This was the last of the Hull class, a slightly modified Forrest Sherman class destroyer, and had some experimental design features, mostly in the engineering spaces. Sadly, most did not work as hoped, and were never put into production. This ship served until 1982. The Turner Joy, along with destroyer Maddox, were the catalyst which started the Viet Nam war. These ships were attacked in the Gulf of Tonkin, and returned fire.

The sharp end of the Turner Joy was it's guns. This was the last class of American destroyer to have guns as it's primary armament. Subsequent destroyer classes would be armed primarily with missiles, and would have guns serving as secondary armament.  The single mount Mk. 42 gun was developed just in time for this class of destroyer, and was a huge improvement over the old double mount guns, of the Second World War destroyers. This class had a pair of these guns mounted in tandem, aft, and a single mount forward. These were radar directed guns, using an automatic loader, feeding from a 20 round drum magazine, below decks. The photo to the left shows the forward gun, while the photo above looks forward from the stern of the ship. These guns are capable of firing a variety of projectiles, including laser guided types. They are still in service, in a number of ship classes, though they were succeeded by the new Mk. 45 lightweight gun, for new construction. The Turner Joy also carried six torpedo tubes, in two triple mounts. It was also one of the first ships to deploy the then new ASROC anti sub missile. The previous class (Forest Sherman) was equipped with depth charge racks, for ASW. For it's day, the Turner Joy was a very advanced ship, having radar, sonar, and these new advanced radar controlled guns. These were primarily Anti submarine ships, and would probably not have done too well under air attack.

The gun was fed from a 20 round drum, and could either be fired remotely, or locally within the mount itself. There was a fourteen man crew for each gun mount, with as many as four being in the mount itself. This is pretty hard to believe, after having been in one. Despite the large size of the mount itself, the interior space is very cramped. The gun is entered through the left hand side, with an access door in the back permitting servicing of the machinery. As large as this mount appears, most of the machinery is below decks.

  Some local students, on a tour group, line up to get inside of the mount.  
  One of the local boys finds his way to the gunners station.  He is looking out of the bubble window, which can be seen on the upper left hand side of the mounting, when viewing from outside.
  Yes, this is just what it looks like. It is the trigger that fires the gun, when it is under local control.  
  This is how you aim, Unfortunately, I have become too much of a portly gentleman to easily fit in some of these tight spaces, and could not quite get into a position, where I could fit my camera to the sighting optics.
The indicator for elevation, and traverse.
  Looking towards the breech of the gun, which is largely hidden by the mechanism for loading, and elevating the barrel.  
  A look towards the rear of the interior of the gun mount.  
  A deck below, is the mechanism and control for aiming the gun, and getting the ammunition from the below decks magazine, to the autoloader of the gun.  
  This control panel may be used to remotely fire the gun. This can be done, either by radar, or by inputting coordinates, the way that an artillery unit of the Army would fire, according to a grid.
  Even further below decks, one more level down, are the ammunition handling and storage areas. These guns are fed by a twenty round drum magazine. This is where the drums are loaded, and contains the mechanism which drives them.
  A look around shows some of the control and  access panels, for the loading mechanism.
  The other main weapon of the traditionally armed destroyer was the torpedo tube. Today, this role is mostly filled by the anti ship missile; but back in the day, a torpedo had double the range of a destroyers main gun, and could pack over five times the explosive power, though a torpedo could not penetrate like a shell. Today, torpedoes are mostly limited to submarine use. The Turner Joy had one triple mount 21" set of tubes on each side.
All of the side decks are generously equipped with rails, nets, and life preserving gear. A  warship might find itself in any kind of seas, and any climate or part of the world. The men must be able to survive, in order to fight.

A hallway (companionway) on the main deck. Note how narrow everything is. Space is at a premium here. In addition, a very rough sea, or a list from battle damage might require a man to brace himself against the bulkhead in order to remain standing.
  If the brains of the ship are on the bridge, and the upper levels, where decisions are made, then the vital organs are below.  A sign on the hatch invites the curious to go below and check out the machinery, living spaces, and working areas of the ship.
  We are now below decks, where most of the work gets done. If the upper decks are the offices, then these lower decks are the factories.  These are also the living and sleeping areas of most of the crew. The stairs, like those of most of the below decks areas, are little more than glorified ladders, with chain railings. From here on in, we are in a windowless place, with no air other than that blown in through the ventilators.
