Your post reminds me of an older post I made about the Tallboy.
"Inspired by recent comments in the Keynes' cruisers story I offer this speculation about how to build a precision guided Tallboy-like all weather bomb using late WW2 technology.
https://en.wikipedia.org/wiki/ASM-A-1_Tarzon
This wikipedia article describes one version of the radio controlled bombs deployed by the Allies late in the war. A key point is they were steered unto their target by the operator visually tracking the bomb which had a flare attached to its tail so as to improve its visibility to the operator. This required daylight operations only in clear or nearly clear weather conditions.
Could these and similar heavy weight bombs have been dropped using radar guidance? Did the USAAF H2X radar of 1945 have the resolution to identify large structures like power stations, industrial complexes or dams. Or ships at sea?
If so then instead of the bomb being fitted with flares for visual tracking have instead a very low power radio transmitter on the same frequency as the H2X radar be fitted to the bomb. Very low power so as to not jam the radar return but instead it would show as a small dot on the radar scope. Also a low power SHF (less than 1 watt) transmitter would not require the cavity magnetron and a large power supply.
The radar operator would find and identify the target. The bomb would be dropped and the bombardier using the same or possibly a repeater scope would steer the dot onto the radar target using the same RAZON system. This system allows high altitude precision bombing at night and/or in overcast conditions. Opening up many important targets to precision bombing with Tallboys and Grand slam earthquake bombs while reducing the risk to the flight crews since they would bomb at night from at least 30,000 feet.
Ships at sea would also produce a strong radar return. This system could be used for attacking even the largest enemy warship. Even the Yamato would not have survived Tallboy or Grand slam hits. It wouldn't take many. And if it had been attacked at night from 30,000 feet they might not have even know they were being attacked meaning no evasive maneuvering. However if this system works even a maneuvering ship would still be hit.
If something like this had been worked up in 1942 than Barnes Wallis' designs would have shortened the war."
