Re: The Mark-68 Gun Director
My apologies, I haven't stopped by here for a while. I have a couple of thing to add here. According to the 15th addition of Ships and Aircraft of the US Fleet, the Mk-37 GFCS had a Mk-25 radar dish, which was 60 inches in diameter. The Mk-68 GFCS had an SPG-53 radar dish, which is 5 feet (60 inches!) in diameter. So while they are technically different antennas, you can easily kit-bash one for the other.
