Prox or VT fuses were not authorized for use in the ETO until December 1944/January 1945. That is LATE WAR  5" Naval guns are the biggest AAA used in the Pacific by the allies.. they are THE "big guns" for Prox Fuses. They were allowed to use them earlier at sea for AAA since the odds of capture were almost zero. In the ETO 155 VT Fuses were devastating as they could be reliably airburst over massed infantry with incredible results.
There is a very good chow in History channel on its development.. the G Forces involved made the reliability quite difficult to acheive.. amazing they were able to actually.. |
Rgr that. Being mostly PTO fan, I'm not familiar with the history of their usage in ETO
. Will read some more about it, thanks!
