Re: Using Ultra to research the Luftwaffe

A little off-topic but an example of the usefulness of hindsight that was not available to Allied Intelligence at the time new ULTRA material was decrypted. This may make some smile...

In HW 5/651, CX/MSS/R.437/A/43 was the first mention of the R4M rocket.

Here is the Allied assessment (probably in consulation with Dr. Jones, ADI (Science)):

"NOTE - None of the above equipment previously reported. EG/R4M - suggested that R may equal RAUMBILD, stereoscopic principle, and the 4M may indicate some kind of range-finder on a 4-metre base."

Cheers

Rod
