 How do, Tom?

 TW> Been a long time since I have ran across that pone. BUT yes she did

You ran across her? More importantly, did you 'bump' into her? 

 TW> "invent" some sort of a device that improved upon the Submarine
 TW> Torpedo. That was back in the 40's so I doubt it was anything to do
 TW> with Acoustic Tropedos becasue it would many years beflre they were
 TW> put into use. In fact as I recall they didn't get used in WWII very
 TW> much if at all. They were just shoot and pray the ship didn't suddenly
 TW> turn and you missed.
 TW> They of course in most cases shot a spread of three or Four to try and
 TW> anticipate and sudden change in course.

Right, it was too technical to implement during WWII, FWIR. Perhaps it was
a workable system, but developing a prototype could have launched 300-400
conventional torpedoes.

 TW> Just jumped over and did a Google Search and did come across her
 TW> Invention. It was foe a system of Guiding a Torpedo form a partol
 TW> plane. It used a "Frequenct Hopping" system, WELL ahead
of it's time,
 TW> to make the signal fairly jam proof. IT was based o na system of
 TW> synchronizing Player pinaos and other self plating instruments the Co
 TW> Inventor with edy developed i nthe 20's. The radio system even used 88
 TW> different frequencies just like the 88 piano keys. It even used player
 TW> piano rol s i nthe synchroizing system.

Wow...

A) I never knew player pianos were ever synched, even on dry land.
B) Radio jamming was in its infancy then, wasn't it?
C) Sure today, with stepper motors, PLL, and such, but in the Forties!

I'll have a looksee when I get a chance, but WOW!!!

 TW> It was never adapted by the military being rejected by the hard headed
 TW> Military Brass.

Germany didn't have the population to win a war of attrition. USA did. But
I've seen a couple of WW* echoes where that could be better explored.

 TW> After the patent for the system expired it was taken and further
 TW> developed by Sylvania Electronics Systems using electronics instead
 TW> of piano rolls. It became a basic tool for Secure Military
 TW> communications and was installed o nships and first used i nthe
 TW> Blocade of Cuba in 1962. The concept still lives and lies behind
 TW> Anti-Jamming devices used today. An example is the
"MilStar" Defence
 TW> Communications Satellite system.

I can see a few security issues waking up once one searches for
"MilStar anti-jamming." <-|[ Again, I heard the lady had some
kinda brain in her, and what is more appealing than a smart woman that's
easy on the eyes?
