[Milsurplus] U.S. Made "V-1" Buzzbomb Transmitter

[Gene Smar]

Gents:

     Little Boy and Fat Man weapons both used four APS-13 "Archie's" as 
altimeter triggers connected in series-parallel.  Here's a good photo of the 
interior of L-11, the weapon that detonated over Hiroshima: 
http://en.wikipedia.org/wiki/File:Atombombe_Little_Boy.jpg .  Click on the 
photo and click on it again for an enlarged view of the interior showing at 
least two APS-13's arranged around the gun barrel.

      For an interesting discussion see http://cryptome.org/nuke-fuze.htm . 
I find it the cruelest of ironies that Little Boy and Fatman were both 
triggered through the performance of four Yagi-Uda antennas on each weapon.
