 | 153k | The Main Battery Fire Control Unit Director Mk.40 installed in the Fire Control Towers of the North-
Carolina / Iowa Class battleships. Photo taken 1991.
There was one of this type director onboard, located in the Fire Control Tower and served as a controlling station in both the Primary and Auxiliary
method of fire.
It was designated as Main battery Director Three.
The director was initially equipped with MK.3 & later replaced with Mk.27 radar for ranging and training purposes.
The director had built into it a system for target designation between between various Main battery stations.
It also had a Mk.3 computer and a Mk.5 Trunnion Tilt Corrector as a portion of the director, in order that the Fire Control tower may become
a controlling and transmitting station for Auxiliary control of the Battery.
It shows the Target Bearing Transmitter and,on the other side the Target Designator and training Gear Drive and
Trainer's Handwheels, a Spotter's telephone Selector Switch mounted on the Rotating Head and telephone Jack Boxes fitted to the Cable tube.

 | 487k | Looking aft from Fwd.Air Defence, Spot 2, with Main Battery Fire Control Radar Mk.8 atop, aft of that, #3 16-Inch Turret while at Fall River in 1991. This Image was taken from her Forward Air Defence Level.
Note the Mk.8 Main Battery Fire Control Radar atop her Mk.38 Main Battery Fire Control Director (there were two types of this type of director aboard;
one at the top of the foremast structure, designated as Main battery director One, and the other located aft of the stack, designated as Main
Battery Director two- these directors were armored directors with a crew of six.) and the 40mm Loading Machine to the right.
The Mk.8 radar had excellent Range accuracy.
Bearing accuracy was practically as good as optics.
Spotting in range was excellent- fall of shot within one thousand yards of target range was accurate to the nearest one hundred yards.
Spotting in bearing was not practical for small deflection errors.
The antenna was stabilized in level from either two sources, the Stable Vertical in Main battery plot or local rangefinder level.
Range was transmitted to Main Battery plot electrically, each time the Range Unit Transmitter button was depressed.
Generated Range was not at the time (1944-1945) fed back into the Range Unit.
All operating and control units of the radar were mounted in the director.
Later provision was made to move the greater part of the operating and control units down to Main Battery Plot as first installed experimentally on Washington (BB-56).
Operation required one radar operator and the director train operator.

 | 125k | GFCS Mk.57 w.Radar Equipment Mk.34, could control the fire of two or three different calibers simply by throwing some switches to compensate for ballistic differences. | Photograph courtesy of Pieter Bakels. |
 | 128k | Radar Equipment Mk.34 measured Range out to 40,000 yards and permitted observation out to 60,000 yards, provided Range-Rate data and indicated Bearing and Elevation of the Target. | Photograph courtesy of Pieter Bakels. |

 | 32k | The MK.12 radar proved very successful but ineffective against low-flying aircraft such as Japanese torpedo bombers. A parabolic
height-finder, Mk.22 ("Orange Peel"), was therefore mounted alongside (right-hand side) Mk.12. | Photograph courtesy of Pieter Bakels. |

 | 39k | Several radars are visible: the Mk.13 Main Battery Fire Control Radar, 3cm radar within a radome that replaced the earlier Mk.8, the more complex mechanically scanned polyrod array, mounted on top of her large Mk.38 Main Battery Director One with its 26.5 ft stereo (Mk.48) rangefinder.

 | 69k | Above it, the SK-2, with its 17ft dish antenna for long range radar detection of aircraft. Right behind it, the "SG" surface search radar is visible. Barely visible inside the SK-2 dish, the BM interrogator of the Mk.III IFF system without which controllers would be unable to
distinguish friendly from enemy aircraft. | Photograph courtesy of Pieter Bakels. |
 | 32k | On her maintop "SR", a back-up against failure of the SK-2 with its 15ft x 6ft air search antenna. Mounted on a new mast, a second "SG" surface search radar. In front of her tower, directly above a (now removed 36-Inch searchlight), the back-to-back antenna arrangement of her large TDY jammer, covering both low-and high bands, for force screening which proved very useful in the latter part of WWII against both sea and airborne targets.
Behind it on both sides of the fire control tower, another pair (P. /S.) of TDY jammers are visible. On her House Top level, a Mk.12 antenna, mounted on top of a here not visible Mk.37 Secondary Battery Director, which is a replacement for the earlier Mk.4, a fire control radar for the dual purpose, rapid firing, tray loading, 5-Inch/38 Twin Mounts(Mk.28) of the ship.
Breech action of this weapon was semi-automatic with power rammers, which permitted loading at any angle of elevation. These mounts had power driven train, elevation and ammunition hoisting,
with alternate manual operation.
The MK.12 radar proved very successful but
ineffective against low-flying aircraft such as Japanese torpedo bombers. A parabolic
height-finder, Mk.22 ("Orange Peel"), was therefore mounted alongside (right-hand side) Mk.12.

 | 70k | Visible just under the Mk.12 is the Mk.29 radar dish for use with the GFCS (Gun Fire Control System) Mk.57 (this image and below), a 40mm primary control system. It could also be used to deliver 5-Inch/38Cal. gun orders instead of 40mm gun orders by throwing several ballistic switches in the equipment.
Early Mk.57 director installations, lacking a fuze computer and parallax corrector, were used for 40mm gun control only. GFCS Mk.57 used manual tracking and radar range.
"Blind" tracking was aided by a "smoothing control", damping the lead angles measured by the computer (Mk.17). In front of the Mk.12/22, a short-range ship-to-ship whip antenna. The small antenna mounted centrally in front of the main antenna was used for Side lobe suppression.

 | 371k | A quote made by Fleet Adm. Chester W. Nimitz is inscribed on a granite wall at the National World War II Memorial located on the National Mall in Washington, D.C. Fleet Adm. Nimitz was the United States signatory to the surrender terms aboard the battleship Missouri (BB-63) in Tokyo Bay, Japan on 2 Sept. 1945, thus ending World War II. Established by the American Battle Monuments Commission, the memorial honors all military veterans of World War II, the citizens on the home front, the nation at large, and the high moral purpose and idealism that motivated the nation's call to arms. On 29 May 2004, the memorial will be formally dedicated with an estimated 200,000 people expected to attend, and includes 100,000 visiting veterans of all wars. | U.S. Navy photo # N-0295M-011 by Photographer's Mate 2nd Class Daniel J.
