L'Arsenal has another fine detail set for the modeler of the World War Two warships of the USN, the Mk 37 Mod. 17 five-inch gun director. Earlier L'Arsenal released a Mk 37 director (Click for review of the L'Arsenal Early Mk 37)but it was the early mount. The Mk 37 Mod. 17 has significant differences to be found in the mount housing. The original Mk 37 had three series of three panels on the top and from facets of the mount. The Mod. 17 cut back this number to five total and added a commander's cupola to the left front face. The radar arrays of the brass photo-etch Mk 12 and Mk 22 are the same but the director housing and ends of the optical range finder are very different in appearance.
The Mk 37 director was the culmination of the evolution of gun directors in the USN in World War Two. First begun in 1936,the Mk 37 was first tested in 1939. For the first time the range finding mechanism was called a computer. Capable of tracking aircraft flying up to 400 mph vertical or 250 mph vertical, it was capable of tracking almost any threat. The Mk 37 was given a flat top as it was designed to accommodate radar from the beginning. Starting in 1941 Mk 4 DP radars were fitted to the Mk 37 but this was followed by the combination Mk 12 DP radar and Mk 22 "Orange Peel" AA radar. L'Arsenal is producing the Mk 37 Mod. 17 director in combination with the MK12 & 22 radars in 1:350 scale. These photographs show the production parts with the resin Mk 37 Mod. 17 body and photo-etched brass radars.
