A little more on SPG-59 -- here's the tangled nest of waveguides (with many removed) on the 3,400-element test installation on land. The calculating sphere is visible.

Of course, to preserve phase information, each of these had to be the same length to within a fraction of the wavelength of the radar.

You can imagine why this design did not mature into a practical service system! Planar phased arrays required much more in the way of computer horsepower, but were fantastically more practical with another ten or fifteen years of technological development.

Here is some much more in-depth further reading (PDF warning). I may need to revise my receiver-array setup.

I'm wondering how many people will actually use the SPG-59. Even the small one was a beast with huge power consumption.

After deliberation I think I might sit this one out as its out of my comfort zone.
If I do sot this out, then I'm more than willing to be a judge.

I can be a judge too as I propably wont have time to participate in this. Also as with Hood, USN ships are not my specialty at all

Not joining in Colo?

Hm, seems that with Hood, Golly, you and me, we've got enough judges.
