Go ahead and post it and I'll download it on Friday, since I will be busy for the next few evenings. We can call it Mk. 28 Mod 1.
Btw, what is the acoustic depth? Is that the min. depth that the torpedo has to run to get a good signal?
I couldn't find much information on the acoustic performance characteristics to compare the Mk. 24/27 to the Mk. 28. I know the former were developed by Bell Telephone Laboratories and the latter by Westinghouse.
