	Subject: Voge speed spread diagram I am looking for a picture and/or info about the Voge speed spread diagram, used on WW2 subs to aid in computing firing solutions. It was created by LCDR Voge while he was in command of USS SAILFISH in early 1942. The diagram was in graph format and was based upon 200% target length coverage with a divergent spread. Don't know more about it but would be interested in any info you might have. Thanks, Urge
