That is just the the thing I have looked around before and there does not seem to be very much information on the exact capabilities of the ST. "US Navy Submarines Through 1945" goes into about as much technical detail as I can find on it.Because it used 3cm bandwith I know that it could not have had much range 10,000 yds in the most ideal conditions.It really had a range closer to 8,000yds.Of course we are also talking about an antenna that is only going to to be at most maybe 5 ft above the surface of the seas and that also reduces range.

Remember that it was a ranging radar and we know that most US Navy submarine attacks occurred from within 5,000yds.


It seems that the various radar sets had separate manuals because radar is not covered in any real detail within the Fleet Submarine manuals i know because I looked through all of them.

In the periscope manual it does describe how to test the ST but gives no information on how it was used or any information as to its range.In the manual it is clear that the set could use more than one frequency which would make it ever more difficult to detect.

Based on written information in books it seems like the ST was not "instant" you had to hold it on a target for several seconds to get a return.

I did find a manual for all types of radar in the US Navy it does not cover the ST or the SV though you can reason that the ST given its small size would not have had a very long range.

I figured 10,000 would be pushing it, i'd be ok with 5,000 yards.ill have to look up Thunder Below and see what Fluckey had to say about it, I remember he had in Barb I think for her last patrol
