AN/SPQ-9A came in a randome only. You could probably convert a SPG-60 from a SPG-51. The AN/SPS-52 is available as a photoetch from several vendors. AN/SPG-60 was deployed on the Spruance, Kidd, Virginia, California, and Tarawa class ships. Gold metal models has the SPS-52 in 2 or three of its 1/350 photoetch kits. Nope.
I wish I could find a kit of a Spruance or a Ticonderoga class ship it would make things soooo much easier. For the SPQ-9 dome i can’t find any references on size. I have some pictures but no points to set the size. As for the SPS-52 is its size close to the SPS-49 that Gold Metal Models has? If it is I can use it and hope no one notices. If I knew that I was going to have this problem 22 years ago I would have gone and asked the guys that worked on these radars this info, I just worked on the AN/SPG-51.
According to the Naval institute guide to naval weapons systems 1997-1998 the randome for the AN/SPQ-9A is an oblate spheroid. Its horizontal axis is 120 inches, and vertical is 96 inches.
The Diameter of the AN/SPG-51 is 92 inches. The antenna for the AN/SPG-60 was used for the STIR radar on the Oliver Hazard Perry class FFG. The AN/SPS-52 antenna is smaller than the SPS-48. The SPS-48 is 17 feet by 17½ feet.
On my box scale (close to 1/300) USS Ramsey kit from Monogram, I had to scratch build a new SPS-52 radar, as the one with the kit is inaccurate. It was very easily made from sheet & strip plastic and some very fine mesh. I have not tackled the very similar SPG-51completely yet. I have only thinned down the kit dish so far and will add some brass later on.
I have the Dragon 1/350 USS Kidd (Kidd class), USS Ingersoll (Spruance Class), and USS Bunker Hill (Ticonderoga class) in my stash. Do you need measurements of those systems in 1/350 scale (that I can do) or are you looking to pirate those parts (that I will not do) for your build? Those kits are pretty easy to find online. Italeri has also reboxed and released them I believe.
The Radar that shipped with the Monogram USS Ramsey isn’t the AN/SPS-52, it is an earlier version of that radar classified as the AN/SPS-39. It was an early 3D air search radar. It’s just plain ugly, Monogram didn’t mess it up.
